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.


Winter conservatory use is much pleasanter with the right window film in place

The colder, darker and wetter months may not be a time of year when you would ordinarily expect many heat and glare problems at your home. However, the fact remains that these issues can occur during any season. In fact, the low-lying sun might make glare an inconvenience that necessitates some kind of urgent solution – including in your conservatory, or wherever rooflights are installed.

This is where such solutions as the solar reflective films for polycarbonate that we supply here at Opalux can really come into their own.

These are both heat and glare reduction films that differ from the many other such films we provide, given their special adhesive that prevents them from bubbling up when applied to plastic rather than glass. But what else makes these films so different and special?

Take your pick from our interior or exterior product

As is the case elsewhere in our range of heat and glare reduction films, our solar reflective films for polycarbonate come in versions that are designed to be installed on the outside surface of the conservatory window or rooflight, and on the inside.

The interior film is the widely acclaimed Opalux Suncool (SO-10SC-iBF) product that takes the form of a translucent metallised film. It can be depended on to provide immediate shading and relief from the sun’s harsh rays, during those times – even during the winter – when there can be an outbreak of such sun.

If, however, you are specifically on the lookout for a film that can be applied on the outside surface of your rooflight or conservatory window, it is another Opalux product – the External Reflective Silver 20 for Polycarbonate film (SO-20RS-eBFSR) – that can come to your rescue.

This film’s performance statistics tell their own story about its effectiveness in repelling heat gain and glare. Not only does this product reflect 50% of solar energy and absorb a further 35%, but it also reduces glare by 81% and filters out up to 99% of harmful ultraviolet (UV) rays. All of this is good news for your interior furnishings, as well as your own health. 

The appearance of this film from the outside, meanwhile, is silver reflective during the day, and a much less noticeable light tint on the inside.

Benefit from a much more hospitable interior space this Christmas

The festive season may bring a whole host of priorities that don’t apply at any other time of year, but one of the last things that you will want to have to experience is unexpected heat and glare making for a less-than-pleasant experience in your conservatory or similar space.

This is why our technical department here at Opalux would be delighted to assist you in your efforts to select the most appropriate film for your own setting, even visiting your site if necessary, before providing a competitive and accurate quote.

Call 0845 026 1125 or email today for a more in-depth discussion of your requirements, so that we can guide you to the most suitable options among our acclaimed heat and glare reduction films.


Both convenient and sophisticated, our anti-graffiti window films will give you peace of mind

Graffiti is a truly unwanted blight on our communities. However, it can be even more problematic when found on windows, given the need it often causes to have entire vandalised panels replaced – unless, that is, some kind of protection has been applied to the glass beforehand.

It is such protection that can be provided by the anti-graffiti window films we manufacture and supply here at Opalux. This film works on a straightforward basis; it acts as an optically clear sacrificial coating that absorbs any graffiti applied to it. As a result, the film can be simply removed and replaced with a new film to restore the window’s previously immaculate appearance.

How and where may these films be used?

It is important to appreciate that the window films in our anti-graffiti range here at Opalux are not, strictly speaking, designed solely for the purpose of protecting a window against graffiti.

That’s because they are, in fact, safety and security films, which means you can also count on them to make your building’s glass safer. This is achieved by not only strengthening the glass against the risk of breakage, but also helping to hold together dangerous shards of shattered glass in the event that the glass does break.

In addition, while these films are by no means heat reduction films, they do reject a consistent 19-20% of solar energy that comes into contact with the glass. Moreover, they filter out 98-99% of harmful ultraviolet (UV) rays, showing a versatility that helps to make these films invaluable for more reasons than one, right through the year.

Finally, one cannot forget – of course – these window films’ considerable usefulness as anti-graffiti films. With the thickness of these films varying between 100-micron and 200-micron, they are highly effective at preventing glass from being scratched or etched by graffiti operators. However, the thicker films in this range are recommended in settings where there is a strong chance of heavy-duty tools being used to apply the graffiti.

A full range of window films to cater to your specific needs

There is a broad variety of purposes that window films can serve, encompassing the likes of privacy management, solar protection, safety and security enhancement and visual effects.

So, if you are unsure as to the product that will be the best match to your requirements as a specifier or end user, our technical team here at Opalux will be delighted to provide you with the necessary guidance.

Indeed, every prospective customer of ours is urged to get in touch with us before making any product decision; simply call +44 (0)845 026 1125 or email for all of the information and advice you will need, along with a free survey and quote.


Privacy can be achieved in so many ways with Opalux window film

The task of ensuring privacy for the occupants of an internal space so often goes hand-in-hand with effective light management, which helps to explain why Opalux has such a stellar reputation as a supplier of window film with true privacy-boosting credentials.

One only needs to browse our current range of privacy-oriented window films, in fact, to see such options as standard translucent privacy films, frosted vinyl plotter-cut graphics, patterned films for semi-privacy, and digitally printed translucent designer films.

So, which of these window films are likely to represent the best choice for your own privacy requirements or those of the end user that you are specifying such products for?

For both total or semi-privacy, our standard translucent films may do the job

Our highly regarded standard translucent privacy screening films – namely the Fine Acid Etch – White (PA902) and Frost Vinyl (PV900) products – are proven, versatile options. Both of these films sport a finely textured matt finish, are suitable for application to new and existing glass alike, and can provide two-way privacy without seriously reducing levels of natural light.

These particular films allow for a high level of freedom in the initial glass specification, so that it can be determined at a later date precisely where privacy is and isn’t required. There may be certain areas like meeting rooms and reception areas, for example, where total screening isn’t needed, a certain level of through-vision being acceptable or desirable.

All in all, such translucent window film does a great job of providing the exact level of privacy needed in a variety of settings, while giving the user the scope to remove, replace or update the film over time in line with changes in how the spaces are used.

But we also offer many other specialised solutions

Naturally, it might be the case that your needs as a specifier or end user deviate slightly from those set out above. If so, an alternative product from our range of privacy window film may be the best one for your given setting.

Those alternative options include, among others, our opaque privacy films, which are not see-through or translucent, but do not entirely block all light transmitted through the glass. In the event that the latter is a benefit you do seek in a privacy window film, we can supply dedicated total light-block film instead.

Finally, if it is one-way privacy that you would like to achieve with a daylight-facing window, this can be achieved by fitting a solar reflective film or dual reflective film, a mirrored finish being provided from the outside.

In short, you have a lot of options for privacy-enhancing window film when you source such a product from Opalux. This, in turn, is one reason why we would always urge you to get in touch with our company directly when you are attempting to select the best possible solution.

Call +44 (0)845 026 1125 or email, and we will be able to discuss your requirements for such a window film, and guide you to a solution that ideally matches your aesthetic, practical and budgetary priorities alike.

Opalux external low-mirror films combine a subtle appearance with high performance

For many of those seeking to purchase our solar protection window film here at Opalux, there can often be a friction between the competing priorities of aesthetics and practicality. Yes, you are probably motivated to order such window film in the first place due to a wish to better protect a building’s occupants from the adverse effects of excessive heat and glare... but a given film not having the right look for the building for which it is intended, could be a deal-breaker.

That’s one reason why we are proud to be able to offer low-mirror film alongside the reflective films that you may have initially considered for your building. As its name suggests, the former type of film doesn’t have the latter’s highly mirrored outside appearance, its more neutral look lending itself well to architecturally sensitive settings, such as historic buildings.

But what if it isn’t either possible or advisable to have such solar protection window film fitted on the internal surface of the given building’s glass? In that case, you may have good reason to look to our externally applied low-mirror window films.

So many benefits beyond their exterior-grade construction 

As you might imagine, a window film that is installed on the exterior surface of a building’s glass needs to be able to resist the weather and other elements that could otherwise cause it to deteriorate quickly. That’s why our external low-mirror window films have been made to be true exterior-grade films, complete with a scratch-resistant coating and long warranties.

But it isn’t, of course, just their strength in the face of adverse outdoor conditions that makes our external low-mirror window films such a fine choice. That’s because they also have that low-mirror appearance, in the two available hues of grey and bronze. These are understated window films from the inside, too, simply giving off a light tint.

Then, there is the formidable performance that these products deliver as solar protection window film to consider. When you wish to achieve significant heat and glare reduction, in the process providing a better experience for the occupants of your buildings and helping to reduce energy costs in the long run, these are films that you can depend on. Indeed, their credentials are strengthened further by their high level of filtering of potentially harmful ultraviolet (UV) rays.

Equip your building with only the best solar protection window film

With an extensive range of window film products available from Opalux, we’re the people to talk to when you are in need of a film that will bring real results in terms of appearance, heat control, glare reduction and any number of other aesthetic and practical needs.

Simply email or call 0845 026 1125 now to ask us any questions about the window films that may best suit your needs, as well as to arrange a free survey.



If you want to reduce glare as much as possible, which window film should you choose?

As will be appreciated by anyone who has ever needed to make a decision on the most suitable window film to reduce glare for a particular building, it is by no means only the glare reduction statistics for a range of films that will guide the ultimate choice of which product to order.

Nonetheless, it is still instructive to look closely at these figures when you are specifying window film for a building where glare could otherwise be a major problem. It is also important to inform yourself as to which of our window films are geared towards glare reduction at all.

Which window films of ours are unsuitable for reducing glare?

One category of window film among our present offerings here at Opalux that does not lend itself well to significant glare reduction, is our clear heat control film. These products are, however, otherwise state-of-the-art, due to their effectiveness at rejecting solar heat and ultraviolet (UV) rays while still preserving a ‘natural’ appearance with a high level of visibility through the glass.

They are not, though, window films to purchase if glare reduction is a priority. Indeed, the typical buyer of such films will either be unconcerned about glare, or will have ensured it is dealt with by other means, such as the use of curtains, blinds and awnings.

So, how do our other products compare?

If you are seeking out glass window film to reduce glare, it is ultimately either our solar reflective or low-mirror films that you will be choosing between. Our Reflective – Silver 20 film (SO-20RS-iSR), for example, is capable of decreasing glare by a whopping 82%, while its Lower Mirror – Neutral Grey 20 (SO-20NG-iSR) counterpart is similarly impressive, providing 80% glare reduction.

There is, however, another category of heat and glare control film here at Opalux that is aimed at those whose windows aren’t glass at all. For polycarbonate windows and rooflights, such as those found on conservatories, we can offer such highly effective products as External Reflective Silver 20 for Polycarbonate (SO-20RS-eBFSR), which delivers its own very impressive glare reduction of 81%.

Don’t accept anything less than the best in window film

All in all, whatever your exact requirements may be when you are in the market for window film to reduce glare – even beyond the glare reduction requirement itself – you can be sure of being guided to the right choice with the assistance of our team here at Opalux.

Get in touch directly with our friendly and informed professionals now to discuss your needs from your next window film, whether you are a specifier or end user. When you do, we will be able to arrange a free survey and quotation, so that you also benefit from the very best value for money.

Our internally applied heat reflective material for windows continues to deliver the goods

If it is a Google search for ‘heat reflective material for windows’ that has brought you to this page, you are presumably on the lookout for a solution that will reflect or repel the heat that can otherwise so easily rise and make your buildings’ internal spaces less than pleasant places to be.

Indeed, on the subject of internal spaces, it is important to note that such heat reflective material – otherwise known as window film – is available for both internal and external application.

While there are certain contexts in which internally applied film will make the most sense and others in which you may deem an external window film to be the best choice, an internal film undoubtedly offers convenience when it is not necessarily easy or simple to access the outer surface of your building’s glass.

So, what solar reflective films for internal application do we presently have in our stock here at Opalux, and what benefits will you be able to expect?

Different window films suit different requirements

While the basic principle of heat reflective material for windows as mentioned above may remain the same across the wide range of products on the market, we do see customers with many different requirements here at Opalux, and therefore seek to provide the most specialised and suitable window films for them.

You are likely to look to our Reflective – Silver 20 (SO-20RS-iSR) product, for instance, if it is the very best possible level of heat rejection that you desire in your choice of internally applied film. This product transmits just 13% of solar energy, while reflecting 52% of this energy and absorbing 35% of it. It also offers remarkable glare reduction capabilities of 82%.

However, while this particular window film is an excellent solution for tackling severe solar heat gains and glare problems in a building, all of this does mean lower levels of visible light are transmitted through the glass.

If, then, you require a higher amount of visible light transmission and are prepared to also accept a higher level of solar energy transmission and lower glare reduction to accommodate this, such a product as our Reflective – Silver 35 (SO-35RS-iSR) or Reflective – Silver 50 (SO-50RS-iSR) film may turn out to be more suitable.

Don’t accept anything less than an industry-leading product

Whatever window film you purchase from Opalux, you can be sure of the same impeccable standards of design, manufacture and effectiveness, as we have become renowned for over the decades since we were established in 1976. Our professional and friendly customer service team can also provide highly responsive and informed technical support.

Let’s ensure that you benefit from only the finest possible heat reflective material for windows, whether as a specifier or end user; call the Opalux team now, on 0845 026 1125, for all of the assistance and guidance you’ll need, as well as a competitive quote.


Your plastic conservatory rooflight deserves the right heat reduction film, too

While this time of year is one during which many of us retreat indoors a little more often than may have been the case during the summer, that doesn’t necessarily mean excessive heat ceases to be an issue.

The British weather has long been unpredictable in that way, of course. However, it may be that while you are enjoying your conservatory, you soon become aware of what heat reduction films like those from the Opalux brand could do for your experience of using such a building.

Polycarbonate windows and traditional window film sadly don’t mix

Unfortunately, if you were concerned about the adverse effects of high levels of ultraviolet rays (UV) and heat passing through your plastic conservatory rooflight to the space below – for example, discomfort for the users of the conservatory, or the quick deterioration of interior fabrics – you would probably be left dissatisfied by a ‘conventional’ reflective window film.

That’s because – as effective as such heat reduction films can undoubtedly be when applied to glass – they can have a tendency to bubble up if they are instead fitted to a plastic surface.

Thankfully, we have the perfect alternative product here at Opalux, in the form of our solar reflective film for polycarbonate windows and rooflights. There are both interior and exterior variants of this product available, depending on your preferences and requirements, and both have an exceptional track record of helping to make conservatories and similar buildings much pleasanter places to be, whatever the season.

Films that answer all of your pressing needs

While the interior version of this film is the renowned translucent metallised Opalux Suncool product (SO-10SC-iBF) that has its own great reputation for providing immediate shading and relief from the sun’s rays, the exterior version (SO-20RS-eBFSR) should also not be overlooked.

The latter film is, of course, designed to be installed on the outside surface of a polycarbonate window or rooflight, and brings a host of benefits – including impeccable solar heat and glare reduction and one-way privacy during the day.

As aforementioned, you may also specify such films as the above if you are worried about the lifespan of your furniture and furnishings being shortened as a result of them being constantly exposed to the harshness of the sun. Sure enough, these particular heat reduction films are highly trusted as a solution in this regard, thanks to their powerful filtering of damaging UV rays.

We can help you to make the most appropriate choice

Don’t forget, too, that it’s very easy to ensure you select the right heat reduction window film for your requirements when you simply get in touch directly with the Opalux team, as you can do by calling 0845 026 1125.

When you take this step, we will be able to answer any technical questions you may have, in addition to arranging an on-site visit if necessary, so that we can give you an accurate and competitive quote.
