We’re approaching conservatory season – but there’s one potential problem...

Britain seems to be very much a nation of conservatories and the people who love them. Certainly, here at Opalux, we believe there’s nothing quite like being able to relax in one’s own conservatory, perhaps while reading a book or tapping away at a laptop. Conservatory ownership and use can be an utter pleasure – until the very moment that it isn’t.

We are referring, of course, to the excessive heat and glare problems that can sometimes make conservatories less than pleasant places to be, at the very time of year when we might most look forward to using them.

Some potential solutions make more sense than others

You might have considered various potential remedies for restoring a hospitable environment to your conservatory. A lot of conservatory owners look into having shutters or blinds installed, for example. However, this might have undesirable consequences for the conservatory’s appearance, to say nothing of the need to constantly get up over the course of the day to adjust such window coverings.

If it is excessive heat gain rather than glare that is your biggest problem, you might open a window or door, or consider more sophisticated ventilation solutions. But again, these measures can be a hassle, and leaving a window or door open could also be a security risk.

There’s no need to compromise when you select our heat reflective material for windows

Thankfully, a solution exists that really can be installed at your conservatory, and then forgotten about. We are referring to our solar reflective films that are specifically designed to be fitted to polycarbonate windows or rooflights, with options available for both interior and exterior application.

The ‘polycarbonate’ aspect is an important detail, given that if you apply a standard reflective film on your conservatory windows or rooflights, it is likely to bubble up. This won’t be a problem when you instead select our heat reflective material for windows made from polycarbonate, thanks to the special adhesive that they use.

What options do we give you for this highly-rated film?

As we mentioned above, we can give you both internally and externally applied versions of this product. The film meant for interior installation is the well-known Opalux Suncool SO-10SC-iBF solution, while the exterior product is External Reflective Silver 20 for Polycarbonate (SO-20RS-eBFSR).

To give you an idea of the performance that can be expected, the latter film transmits just 15% of solar energy, reflecting 50% and absorbing 35%. It also filters out 99% of ultraviolet (UV) rays and reduces glare by a whopping 81%.

When you are looking for conservatory-ready heat reflective material for windows that can be depended on to significantly cut solar heat and glare while also being scratch-resistant and reducing energy use for cooling, you can’t expect to find a superior product anywhere.

Now’s the time to talk to our friendly and capable team

It may ‘only’ be March, but now is the time of year when we often start to see a surge in demand for window film products for conservatories like yours – so don’t wait too much longer to purchase!

Call the Opalux technical department now on 0845 026 1125 or email, and we will provide advice in light of your specific needs, in addition to a highly competitive quote for the most suitable product.


Just a few of the functions that Opalux solar control films could serve at your premises

When many end users and specifiers enquire to us about sourcing an Opalux window film, they may initially have in mind something with a very specific purpose. They might desire the best window film to reduce glare at their premises, for instance, or it may be the product that would be most effective at lowering oppressive summertime heat that is of most interest to them at first.

However, it is any one or more of the following benefits that you might actually receive from your final Opalux window film, depending on the product you ultimately choose.

Improved aesthetics

Window film can really help to provide a more uniform look to glass than might otherwise be the case. With both reflective and low-mirror products available right now from Opalux, we can help you to achieve the appearance – whether mirrored or muted – that you feel would best suit your own buildings.

Glare reduction

This is one of the most common reasons that prospective customers of ours have for requesting solar control film. Glare can be a menace that prevents the occupants of buildings from using premises comfortably and productively. This, in turn, could make window film to reduce glare a better alternative to such measures as blinds or having trees planted near buildings.

The rejection of heat gain

Both overly warm and overly cold environments can be less-than-optimal ones in which to work for people in offices and similar premises across the UK. Nonetheless, at this time of year, it is excessive rises in temperatures that are likely to be the biggest problem. A dedicated window film could therefore be greatly useful for repelling a large proportion of the heat that would otherwise imperil occupants’ comfort.

Enhanced privacy

While the change in appearance that Opalux solar control films often bring to the glass to which they are applied is in many ways simply a consequence of the window film needing a tint if it is to have solar protective properties, there’s another pleasant side effect that such tinting can bring: greater privacy for those inside the buildings. Our solar reflective films, for instance, are known for their silver mirrored external look during the day, which prevents those from outside easily peering through the glass.

Better safety and security

While making your buildings less vulnerable to the whims of wrongdoing intruders might not be your very first priority when you are in the market for solar protection window film, we certainly offer solutions here at Opalux that combine these qualities. We offer dedicated safety and security films, for instance, that filter out up to 99% of potentially harmful ultraviolet (UV) rays, while also being strong against attempts to break the glass, and helping to hold together shards of shattered glass if breakage does occur.

As you can hopefully see from the above examples, specifiers and end users with responsibility for buildings don’t need to limit themselves to purely seeking out the best-suited window film to reduce glare or heat gain.

Instead, multiple benefits can be offered by one product – and when you contact our technical department today, we can assist in directing you to the film that would represent the best match to your preferences and requirements. 

Now is the time to invest in solar protection window film for the spring and summer

Whether as a specifier or end user, you might have noticed the brightening skies and creeping temperatures in recent weeks, and considered the implications that this will have for the buildings for which you have responsibility, and the people using such premises.

If – as has been the case in certain parts of the UK lately – snow has been falling near your buildings, it might not seem that purchasing a product to repel excessive heat gain and glare should be much of a priority for you. But you can be sure that such conditions will arise during the spring and summer, with all of the consequences they'll have for users of your residential or commercial sites.

In that situation, you won't want to be caught out and have to rush your decision to buy solar protection window film, especially given the sheer wealth of such products available through suppliers like Opalux. In short, now is the time to start comparing your options.

You'll have a lot to think about when picking between window films

Presumably, if you're specifically on the lookout for solar protection window film, your main priority in such a film will be solar protection. Sure enough, we have solutions across our range here at Opalux, that offer various levels of heat rejection and glare control, to help to ensure the continued comfort and productivity of your buildings' users throughout the summer months.

These characteristics must also be balanced, however, with such other factors as cost, visuals and where the window film in question is to be installed. We offer both internally applied and externally applied versions of our solar reflective and low-mirror window films, for instance, with the external films sporting a more durable construction to enable them to withstand outdoor conditions.

But you will also want to consider whether the premises where the solar protection window film is to be applied better suit the highly mirrored, but uniform appearance of our reflective films, or instead the much more muted and neutral aesthetic of our low-mirror films.

Speaking of appearance, clear heat control films can also be sourced from us, for those settings - such as retail shops and motor showrooms – where it really is imperative for the highest level of visibility through the windows to be maintained.

Dedicated solar reflective films for polycarbonate are available from us, too. These particular films are designed for use on polycarbonate windows or skylights, and are much better suited to this job than standard reflective films, which tend to bubble up when applied to plastic rather than glass.

Take the time now to seek the right advice about window films

One of the other reasons we're asking you to take action now on sourcing solar reflective window film, is the simple fact that it can take a little while to decide on the ideal one for your intended application. Indeed, you will require specialist advice if you are to be absolutely sure of making the right choice for your buildings.

Such advice can be sought right now from the Opalux technical team, who can be reached by calling +44 (0)845 026 1125 or emailing Don't hesitate to contact us now to ensure you are as well-informed as possible before selecting a given solar protection window film, as well as to request your free survey and quotation.


The best glare reduction films do so much more than just reduce glare

Glare, it is fair to say, is a real menace for many office workers and other occupants of commercial buildings. It can be an issue right through the year, but it is often as the spring and summer loom that end users and specifiers consider more formal arrangements for tackling it in their buildings – especially as it is during these seasons that excessive heat tends to become more of a worry as well.

There are various ways in which one may conceivably control the amount and/or impact of glare in a given interior space, including adjusting the light levels and rearranging where computer screens are positioned. Another option, though, is to look to dedicated glare reduction films.

Such window films provide a direct intervention between a window and an interior space to help to make troubling and distracting glare a thing of the past. What you might not have realised if you are interested in glare reduction films, however, is just how useful the leading ones can be in a wide range of other ways, including to enhance the appearance of a building, reject excessive heat gain, and maximise the privacy of occupants.

We have the window film that will suit your own setting 

Whether you are a specifier or end user, it is important to be aware of the very real differences between different glare reduction films, in light of your specific requirements.

The options that we can presently offer here at Opalux, for example, include solar reflective mirrored films such as the Reflective – Silver 20 (SO-20RS-iSR), which doesn’t merely reduce glare by 82%, but also rejects 78% in total solar energy, and filters up to 99% of potentially harmful ultraviolet (UV) rays. Such effects help to make a building’s occupants more comfortable, in addition to reducing energy tax liability and boosting their daytime privacy, thanks to the reflective outward appearance.

Alternatively, there may be a more architecturally sensitive setting in which you are interested in fitting glare reduction films, and where highly mirrored reflective films would be undesirable. In that case, the much more muted look of our low-mirror films is likely to be much more to your satisfaction. These films are still impressive in their performance, though, as in the example of the Lower Mirror – Neutral Grey 20 product (SO-20NG-iSR), which rejects 70% in total solar energy, transmits 18% of visible light and, of course, slashes glare by 80%.

Talk through your window film needs with our friendly and capable staff

We could cite similar examples of the multidimensional benefits of our glare reduction films right across our range – and if you would like to receive more tailored advice and guidance for your own particular needs, you are very welcome to contact our technical team directly. Give us a call today on 0845 026 1125 for an in-depth discussion, and to arrange a free survey and quotation. 


Do all of our heat reduction films deliver the same level of performance?

Now that we are into February, more and more specifiers and end users are entering a ‘spring’ and ‘summer’ mindset rather than a winter one. It is a transition that also extends to the solutions they may consider for lessening the amount of heat experienced by users of their buildings.

Window films that are specifically dedicated to repelling any excessive rises in temperature can certainly be one convenient and cost-effective solution.

But if you are interested in heat reduction films for your own buildings, can you expect the exact same level of effectiveness, regardless of whether the product you purchase is a solar reflective film, a low-mirror film or a clear heat control one?

The short answer is... no

No type of window film is ever quite the same as another. This is why you are always advised to scrutinise the technical specifications of any particular heat reduction films you look at, and to discuss your requirements with professionals like our own here at Opalux, prior to placing an order.

Such differences are down to the various trade-offs that must be managed when one is attempting to reduce heat through the use of window film.

One good rule of thumb to follow, for instance, is that the more important it is to preserve a natural and clear appearance with the window film you install, the less effective you can often expect the window film that you buy to be at reducing excessive heat and glare from passing through the glass.

This is demonstrated by such an acclaimed clear heat control film of ours as the Specialist Heat Control – Clear (SO-70IR-iSR) product, which – while it transmits 67% visible light to ensure a clear and natural look – also transmits 50% solar energy, with the rest being reflected or absorbed. Nonetheless, this may still be a perfectly satisfactory level of heat rejection for the kind of setting where this film is likely to be used, such as a retail store or motor showroom.

If, though, it is maximum heat rejection that you desire in a window film, and you are not concerned at all about enabling those outside to continue seeing through the glass, such a solution as our Reflective – Silver 20 (SO-20RS-iSR) film is likely to be much more appropriate.

This particular film rejects a total of 78% solar energy, but also has a highly reflective and uniform external appearance during the day. This makes it difficult for outsiders to look through the window – a potentially very significant privacy and security benefit.

We can point you in the direction of window film that truly works

Even if the rejection of excessive heat gain is a major priority for you when seeking to buy window film for your buildings, the combination of other priorities that you are likely to have makes it crucial to carefully think about these factors before deciding on a given product.

This is a task that can be made much easier when you first get in touch with the Opalux team. You are welcome to call us on 0845 026 1125 or email, whether to ask us any technical questions, arrange a survey or request a quote, to ensure you really do benefit from the very best-suited product, at the right price.


Opalux Mani-Fest® is a simple, fuss-free health and safety solution

Glancing at much of our online window film range, it might be easy to think that here at Opalux, we only supply products for the purposes of repelling excessive heat gain, minimising glare, maximising security and/or enhancing privacy.

But that is not, of course, the case, especially given that we are also such a reputable source of glazing safety manifestation.

What do we mean by ‘manifestation’, anyway?

Manifestation is the name given to a type of treatment given to many glass surfaces – including glass windows, doors and partitions – in order to maximise their visibility. This, in turn, helps to prevent the users of nearby spaces colliding with the glass, and potentially suffering injury as a result.

We can be your trusted, go-to source of such film

Opalux Mani-Fest® window film is available in standard and bespoke forms alike, to match the most specific requirements you have for the intended setting.

Our standard manifestation, for instance, simply consists of frosted manifestation dots or squares that can be purchased ‘off the shelf’ on 50-metre rolls, or a continuous 50m x 50mm frosted strip.

There’s no more straightforward a way of satisfying the requirements of the Building Regulations and the Workplace Health Safety & Welfare Regulations, with regard to window or glass partition manifestation.

All that you have to do is follow the enclosed fitting instructions, pulling the length required from the roll and ensuring two bands of manifestation are applied to the glass surface in question, aligning with each other vertically, as well as horizontally with adjacent panels.

But we can also answer more demanding needs

If you have slightly more specialised expectations with regard to the glazing manifestation that you wish to purchase from a supplier like Opalux, you may be pleased to learn that we also offer manifestation on a bespoke basis.

This means that by negotiation, you can have Mani-Fest® 50-metre rolls created by us to your own specification. This service is subject to a minimum order quantity of 750 linear metres, and enables you to have manifestation produced that incorporates your own choice of repetitive mark or logo, within certain design limits.

In the event, however, that you would like to enjoy even greater design freedom than this, there is also the option of asking us about freeform manifestation.

Again, the basic purpose of such manifestation is to make the glass easily visible, and therefore safer, except that you will also have the utmost scope to introduce whatever imagery you desire to your building’s office partitions, windows and reception areas.

You’re just a few steps away from the ideal product

Window film in all of its shapes and forms is very much our speciality here at Opalux, and always will be! We’ve been serving end users’ and specifiers’ most discerning window film requirements since 1976, and we can do much the same when you are in the market for glazing manifestation.

Call 0845 026 1125 or email today, and you’ll be able to have the necessary detailed discussion with our technical department, to make sure we devise the most suitable solution together.


Transform your windows’ appearance – or not – with the most suitable window film

Inevitably, if you have reached the point as a specifier or end user where the installation of window film at the property for which you are responsible seems to be the best step for accomplishing certain practical or aesthetic needs, there will be competing priorities that you are forced to carefully consider.

We touched on the aesthetic aspect above, for example, and you only need to casually glance over the range of window films outlined on the Opalux website, to appreciate just how much leading window films can vary in terms of appearance, while also still fulfilling key practical requirements.

The impact of our window films isn’t merely ‘skin-deep’

Many of our customers, for instance, are specifically interested in heat reflective material for windows. This is a type of window film that – whether it is designed to be applied on the inside or outside surface of the glass – literally reflects a certain proportion of the solar energy it comes into contact with. Sure enough, these films also look reflective, sporting a highly mirrored appearance.

However, while some specifiers and end users quite like the opportunity that such film gives them to achieve a uniform look for the glass of the given building at the same time as boosting solar control and privacy, this may not be a very suitable aesthetic for historic and listed buildings.

The fact is that irrespective of your practical needs in the realm of window film, it’s perfectly possible that the building for which you are seeking such a product is of the more architecturally sensitive variety. That’s why a solution that swaps such a mirrored look for something more understated and neutral, such as our low-mirror films, may be the wiser choice for certain settings.

Something else that’s more than possible, though, is that you need to source a high-performing window film for a building where you’d rather the appearance of the windows wasn’t visibly altered at all. In that case, our state-of-the-art clear heat control films may intrigue you, these products being particularly useful for the likes of retail shop windows and motor showrooms.

Looks may not be everything, but they can be very important in your window film

Are you unsure of the exact combination of appearance and performance characteristics that would best suit the environment where you are seeking to have window film installed? Or would you simply like to request a competitive quote, while ensuring the product you are already carefully considering is definitely the one that our technical team would also recommend?

Whatever your specific requirements might be, we would be pleased to assist you here at Opalux; call us now on 0845 026 1125 or email, and we will be able to do precisely that. 


How to make glare less of a problem at your business premises this New Year

In a world in which more and more workers spend a considerable amount of their office time sat in front of and concentrating on a computer screen, glare can be a sometimes surprising compromise to productivity levels.

Even worse is that it is not, contrary to popular belief, an issue that only ever arises during the summer; it is the winter months, after all, when the sun tends to be low in the sky during hours when the typical office staffer is still working.

Regardless, January marks a New Year, as well as the start of a steady transition to more spring-like conditions in the months ahead. This means your office-based firm may need to think increasingly urgently about ways of reducing glare, and putting the chosen solutions into practice before the summer arrives.

So, what could those solutions be?

Plenty of potential measures for reducing glare in an office have long been tried. You might have arranged for those employees of yours who wear glasses to swap them for spectacles incorporating an anti-glare coating, for instance, or you may have attached anti-glare screens to their monitors.

Another possibility could be to rearrange the layout of your office, so that any artificial light sources used in the space are not positioned in a way that makes glare more likely. It’s a similar situation for natural light, too, so ensuring none of the computer screens in your office are directly facing the window – which the sun may sometimes stream through – could be another very wise idea

Alternatively, perhaps you could simply fit some window blinds or curtains around your office? These are an affordable, fuss-free and ‘low-tech’ solution, but they can also collect dust. This is to say nothing, too, of the sheer inconvenience of your employees having to manually adjust them over the course of the day and week, in line with the light conditions at any one time.

There are good reasons why so many firms choose window films

Even if you have never considered using window film to reduce glare, here at Opalux, we can guide you to the product in our renowned range that represents the best match to your full range of requirements.

Window films make great sense as a means of lessening the amount of glare experienced by your workers in 2020. They enable your employees to continue appreciating the view through the glass, without having to continually intervene to ensure glare is actually still being prevented.

Furthermore, our window films are known for their impressive aesthetics and performance, the latter including not only glare reduction, but also the reflection of solar energy gain and the filtering of potentially harmful ultraviolet (UV) rays.

Why not, then, call the Opalux team now on 0845 026 1125, to talk to us in more detail about how the right window film to reduce glare from us could bring benefits extending well beyond glare reduction? When you do, we will also be able to arrange a free survey for you, and provide the most competitive quote you will find in this industry.


When does it make sense to invest in our clear heat control film?

As effective as dedicated solar protection window film can be for such crucial purposes as reducing glare and heat that could otherwise pass through glazing and pose discomfort for the occupants of a building, this type of film often comes with an obvious drawback: the visual one.

Allow us to explain. If you have previously browsed our range of solar protection window film options here on the Opalux website, you might have noticed that they almost all necessitate the appearance of the window to which they are fitted being drastically altered in some way.

In the event, then, that it isn't desirable or even acceptable for your building's windows to be given a reflective or low-mirror look, but you still wish to enjoy at least some of the benefits a solar protection window film can give you, our clear heat control film may seem very appealing. But what are some of the factors you should bear in mind before purchasing it?

This film offers great heat control, but not good glare control

Good examples of settings where our clear heat control films are often fitted include retail shops and motor showrooms - types of business, we're sure you'll agree, that depend to a huge extent on passers-by being able to easily see through the window.

This priority, and the fact that such businesses can have problems with excessive interior heat gain, could mean a clear heat control film from us would be an extremely wise purchase if your own intended application falls into this category.

It's crucial to appreciate, though, that unlike our reflective or low-mirror solar protection window film, our clear heat control films don't do very much to reduce glare. If, then, you ultimately purchase this film, you are strongly advised to have another plan for addressing glare in the intended setting - the use of curtains, blinds or awnings, for instance.

Peruse the specifications of our industry-leading films... and then get in touch

The Opalux website showcases comprehensive information on our clear heat control films. These include the Specialist Heat Control - Clear (SO-70IR-iSR) product, as well as the Supreme XL - IR Heat Control/Clear (SO-70XLIR-iSR) film, both of being these designed for interior application. An exterior film, the Specialist Heat Control Clear External (SO-70IR-eSR) product, is also available.

Once you have familiarised yourself with these possibilities for your next clear solar protection window film, don't wait any longer to enquire directly to the Opalux technical department.

This will enable you to make the big step forward to arranging a quote, so that whether you are a specifier or end user, you can be sure of obtaining the right window film at the right price.


Which is the best glass film to reduce heat and glare – solar reflective or low mirror?

The sheer variety of options for heat and glare control window film might understandably feel a little overwhelming if you are not accustomed to purchasing such products. Nonetheless, for many of our customers here at Opalux, their choice often comes down to one between solar reflective and low mirror film.

The differences between these two broad categories of glass film to reduce heat and glare may seem largely self-explanatory – the former type of film has a highly mirrored, reflective appearance, as opposed to the latter film’s more muted look.

So, what implications do these differences have for the decision you might make when in the market for glass film to reduce heat and glare, and what else do you need to know about these products?

Why the difference in appearance matters at all

First things first – why should it concern you whether the next window film you buy is a solar reflective or low mirror one? The short answer is that your ultimate choice between these two looks will have a big impact on not just the aesthetics of the buildings where these films may be applied, but also certain practical factors.

Solar reflective film, for instance, helps to give your buildings’ glass a uniform reflective look – which in the process, hides internal clutter and occupants from the prying eyes of outside observers.

Those specifiers or end users who especially desire a more neutral appearance, meanwhile, may select a low mirror film. This is likely to be a particularly pressing priority for historic or listed buildings, which are – after all – more architecturally sensitive settings.

Certain outcomes, however, may not vary much at all

Whether or not you ultimately invest in solar reflective or low mirror window film, when you purchase yours from Opalux, you will be able to look forward to the highest standards of performance.

Indeed, in this regard, there may not be much difference at all between the two broad categories of film. Our Reflective – Silver 20 film (SO-20RS-iSR), for example, transmits just 13% of solar energy through the glass, reflecting 52% and absorbing a further 35%. It reduces glare by 82% and filters out as much as 99% of potentially harmful ultraviolet (UV) rays.

This compares to the Lower Mirror – Neutral Grey 20 product (SO-20NG-iSR), with its 14% solar energy transmission, 27% solar energy reflection and 59% solar energy absorption. It lowers glare by 80% and in common with the aforementioned film, provides 99% UV rejection. Both of these films also come with a decade-long product warranty for the greatest peace of mind.

We’ll help you to determine the ideal choice of film

With so many possibilities available on the present market for glass film to reduce heat and glare, it makes sense to get in touch with the Opalux team at the specification stage to ensure you really are making the most appropriate choice of window film for the application you have in mind.

Simply call +44 (0)845 026 1125 or email today to have that conversation, including requesting a free survey and quotation from our highly capable and experienced technical staff.
