Don’t depend on air conditioning alone to keep your company’s offices cool!

It would be easy to presume, as temperatures at your organisation’s premises remain persistently high despite the traditionally cooler time of year we are now entering, that you have little choice but to crank up the air conditioning and hope for the excessive heat to pass. However, it’s important to consider the adverse effects that this could have on your company’s energy bills – and as a consequence, its energy efficiency as well.

No company wishes to pay elevated air conditioning bills at a time when energy seems to be more expensive than it’s ever been – so how could a window film or two from Opalux help to keep everyone in your offices cool for a reasonable price?

We are experts in energy control window film

Just imagine how much less of a requirement your firm will have for air conditioning if it installs a solution that prevents as much as 80% of heat from the sun passing through its glazing and into its buildings. You might think the only thing capable of this would be an expensive piece of equipment, but that’s not the case, as one of our acclaimed window film products can also do the job.

Remember that unlike almost any other option for preserving hospitable temperatures at your company’s premises, a window film is a passive medium. Once you have fitted it to your office’s glazing, you don’t need to operate complex controls or intervene in any other way. Instead, it’ll simply get on with the task of rejecting solar heat gain and as a result, lessen your air conditioning’s load.

With any energy control window film that you purchase also potentially greatly reducing your company’s carbon footprint, there are reasons to invest in such products besides the immediate practical benefit of employees who feel more comfortable and better able to focus on their work.

How much could you hope to save with our energy control film?

Browse our complete selection of heat and glare control window films today – encompassing the likes of solar reflective films, low mirror films, clear heat control films and dual reflective films – to discover the possibilities for window film that not only gives your air conditioning systems less work to do, but also fulfils a variety of other aesthetic preferences and practical needs.

You might even go as far as enquiring about our energy saving computer simulation that enables you to gain a more accurate estimate for how much you could save as a result of the installation of an Opalux window film.

Our low mirror window films are excellent for both glare and heat reduction

Are you, as a specifier or end-user, on the lookout for window film to reduce glare and heat, but without the highly mirrored look that our solar reflective films have? In that case, you might wish to consider our low mirror window films, which provide a more subtle, neutral appearance while still delivering brilliant practical results.

Both internally and externally applicable versions of our low mirror films are available, while you can also choose between the two hues of grey or bronze. But what else do you need to know about the precise specifications of these sought-after window films?

Not all of our low mirror options produce the same results

While our various low mirror window films have certain things in common – including remarkable filtering of ultraviolet (UV) rays while still letting a high level of light to pass through the glass – the exact results that they deliver in other respects can vary.

The distinction between the internal and external versions of this popular film is vital, for instance, because the exterior versions have been designed to withstand the elements. We would therefore strongly advise you not to fit interior low mirror film to the outside of your buildings.

Then, there are the different levels of glare control to consider. Our internally applied Neutral Grey 20 film (SO-20NG-iSR), for instance, is capable of reducing glare by 80%, but this percentage falls to 60% in the case of the Neutral Grey 35 variant (SO-35NG-iSR), and 45% when you choose the Neutral Grey 50 film (SO-50NG-iSR).

If, meanwhile, you are specifically on the lookout for internally applicable bronze low mirror window film to reduce glare, you should note that our Bronze 20 film (SO-50SB-iSR) cuts down glare by 77%, while 55% glare reduction can be expected from the Bronze 35 product (SO-35SB-iSR).

The ideal glare reduction film for more sensitive settings

When there is a pressing need to lessen glare within the buildings used by your organisation – or whatever entity you are serving as a specifier – you don’t need to give up on the idea of installing window film, simply because of what may be the architectural sensitivity of the buildings in question.

Indeed, our low mirror window film to reduce glare here at Opalux is designed squarely to be fitted to properties such as listed buildings, where a more muted visual impact is desired. Call our technical team today on +44 (0)845 026 1125, and we can help you to select the product that best suits your requirements, as well as provide a free survey and quotation. 

Want heat control, but also a natural, clear appearance? We might have just the right film for you

When you are in the market for some form of glass film to reduce heat but don’t need whatever product you buy to also lessen the amount of glare at your business premises, you may understandably find many of the obvious window films on the market to be far from brilliantly-suited to your requirements.

After all, at certain business sites such as retail shops or motor showrooms, there is often extensive glazing in need of glass film to reduce heat. However, a solution like our solar reflective film may be a less than ideal solution, due to the accompanying need for the windows to be kept natural-looking and clear.

If your company premises have this combination of requirements, you may well have ruled out buying any of our low-mirror films for similar reasons. There is, though, an excellent alternative in the form of our clear heat control window films, which really are what they sound like.

A sophisticated solution for lessening heat, but maximising light

The state-of-the-art nature of these spectrally selective window films should not be understated. Our clear heat control films really do go a long way to rejecting the excessive heat gain that may presently be a problem at your workplace, without causing any noticeable appearance in daylight levels or otherwise altering the appearance of the windows at your site.

All of this means that your customers, clients and even employees may not even be aware that you have installed glass film to reduce heat, other than feeling the benefit of much more hospitable conditions.

Although glare control is a key feature of many of our window films, this is not the case for our clear heat control films, not least as the typical users of these products have often already adequately tackled any glare problems by other means, such as through the use of curtains, blinds and awnings.

Order the window film that matches your exact requirements

We’ve always dedicated ourselves here at Opalux to supplying window film for a vast range of potential applications, contexts and needs – and much the same is true of our clear glass film to reduce heat.

Both internal and exterior versions of this innovative film can be specified, delivering the significant minimisation of heat through the windows of your premises that helps to boost comfort and productivity for everyone entering your buildings. In the process, you can also lessen the pressure on your cooling systems and shield interior furnishings from accelerated heat-related deterioration.

Call the Opalux technical department today on 0845 026 1125 to receive informed advice and guidance on the most appropriate window film for your organisation’s circumstances and needs, as well as a free survey and quotation.

What are the best ways to minimise glare in your workplace?

Optimal lighting conditions are essential if the workers in your business’s buildings are to be as productive as you need them to be. All too often, however, this is not the case in workplaces up and down Britain, to such an extent that remedies need to be considered.

Glare – which arises when excessively bright light intrudes into a person’s field of view – is one such problem. Glare can occur directly, such as when sunshine enters through bare windows, but also indirectly, as in the case of light bouncing off highly reflective surfaces.

Various means exist of tackling glare

You may have tried various ways of reducing glare on your company’s premises already, such as the fitting of shades or diffusers to unshielded lamps and bare windows.

Another possibility is to creatively rearrange your organisation’s offices so that light is redirected onto walls or ceilings, away from computer screens or other areas that your employees need to focus on if they are to work effectively.

You may even go as far as having any especially reflective surfaces at your business premises refinished. Meanwhile, if you have moved your workers to a darker area of the office to avoid glare being a problem, you could provide them with task lighting that can be adjusted according to their needs.

When you are devising solutions for glare in your workplace, it is also important to appreciate the often relative nature of the problem, with a bright light source likely to be more of an issue in a room that is otherwise gloomy, than it will be in a well-lit space. Simply equalising differing levels of illumination in one space could therefore greatly help.

Our glare reduction films could be a crucial solution

With both solar reflective and low mirror glare reduction films able to be ordered from Opalux by specifiers and end-users alike, your organisation may need little more than the right window film to achieve a drastic fall in glare at its premises. One product that you may consider is our Reflective – Silver 20 (SO-20RS-iSR) film, for instance, which is capable of minimising glare by an astounding 82%.

There are many more renowned glare reduction films to choose from across the Opalux range, so to receive tailored guidance on which one may be the best match to your own organisation’s application, why not call our technical team now on +44 (0)845 026 1125 or send us an email?

5 strengths of our external reflective solar protection window film

If the amount of solar heat and glare that penetrates your organisation’s buildings is a problem affecting the comfort and productivity of your workers, an obvious step is to invest in appropriate solar protection window film.

But what makes our externally applied reflective films an especially sound choice? Here are just five of their qualities.

Weather resistance

You may choose external rather than internal solar protection window film for various reasons, with the most common justifications including the simple inability to reach the inside of the window, or the glass being a type that doesn’t lend itself well to the internal application of protective film.

Whatever the exact situation for you when you come to purchase this film, you will be thankful for its weather resistance that will ensure it delivers excellent glare and heat control for years to come.

A silver reflective outward appearance

One of the most immediately noticeable aspects of this particular range of solar protection window film is its combination of a uniformly reflective outward appearance and a mere light tint from the inside.

Indeed, such a contrast helps to provide vital privacy for your workers, as they’ll be able to see freely outside, but people outside won’t be able to see easily inside.

The rejection of excessive heat

At this time of year of all times of year, it becomes apparent just how important it is to keep your workers cool, which will be much harder to achieve if harmful ultraviolet (UV) rays can penetrate the glass with ease.

Our Silver 20 and Silver 35 external reflective solar protective films both provide up to 99% screening of such UV rays, which could be crucial to ensuring your staff’s comfort.

The ability to lessen glare

Glaring reflections off computer screens are, at best, distracting, which could greatly hamper your employees’ productivity. In a worse-case scenario, high levels of glare are hardly good for the occupants of your building from a health and safety point of view, either.

That’s why you may be so thankful for the 82% glare reduction that our external Silver 20 film can deliver, as well as the 66% less glare that the Silver 35 film can give you. 

Protection for your interior furnishings, too

The above qualities can also be instrumental in keeping such items as your building’s furniture, fabrics and artworks in optimum condition for longer when you fit our external reflective solar protection window film. These films can therefore save you considerable money and hassle in the long run, in more ways than one.

Opalux is no less than one of the UK’s most trusted window film brands, so why look anywhere else for the solar protection window film that will give you years of impeccable performance and a better environment for everyone using your buildings? Simply contact the Opalux technical team now to arrange your free survey and quotation.

How can you keep your workplace cool during the summer?

With recent news headlines having drawn attention to intensifying heat around the globe, now may be as good a time as any to consider whether your organisation is doing everything it can to protect its workers from the adverse effects of heat.

After all, an overly warm workplace can be problematic in a number of ways. If your staff are to be at their happiest and most productive, you should be looking to keep the temperature at your premises roughly between 13 degrees C (56 degrees F) and 30 degrees C (86 degrees F).

If your workers’ activities are more strenuous than average, it is advised that you target the lower end of this range, whereas for workers involved in activities of a more sedentary nature, a temperature at the higher end will probably be most suitable.

At this time of year in particular, your workplace may be at risk of becoming too hot, rendering your workers more tired and less energetic, as well as more likely to suffer from heat (muscle) cramps. Too much heat could also be responsible for lower concentration that may make your workers more susceptible to accidents.

5 quick tips for helping your workers to cope with the heat

  • Provide desk, pedestal and/or ceiling-mounted fans
  • Ensure windows can be opened
  • Move workstations away from direct sunlight or other heat-radiating objects or situations
  • Allow your workers to take breaks if necessary to get cold drinks or cool down
  • Install heat reduction films like those that we supply here at Opalux

There can be no better source of industry-leading heat reduction films

Solar control is one of our key specialities here at Opalux, which means you can order dedicated films from us that are as effective at reducing glare as they are at lowering the amount of heat experienced by your workers.

Indeed, you don’t merely have a business or moral duty to ensure your workers can focus on their assignments in comfort during this especially hot summer and beyond. That’s because, by installing our heat reduction films, you could also be better fulfilling your legal obligations, in accordance with the Workplace (Health, Safety and Welfare) Regulations.

Our acclaimed Reflective – Solar 20 (SO-20RS-iSR) film, for instance, is capable of rejecting as much as 99% of ultraviolet (UV) light, while also reducing glare by 82%. It is just one of the many trusted and high-performing heat reduction films we are delighted to offer to organisations and premises with a wide range of specialised requirements that may also include privacy and aesthetic concerns.

5 lesser-noticed benefits of Opalux solar control window film

You may initially browse our selection of solar control films here at Opalux with an interest in purchasing the product that will best reduce the amount of heat that builds up in your buildings or those to which you are looking to fit such window film.

However, such films can also bring many other less-often-publicised advantages, such as the below.

Maximum control over glazing appearance

If you are interested in buying this type of window film for a practical purpose, you may be concerned about it having an undesirable effect on the way the given building’s glazing looks.

Thankfully, we can supply solar control films here at Opalux that also offer just the right appearance for the given application – whether you would prefer a reflective uniform appearance, a muted grey or bronze aesthetic, or no discernible cosmetic difference at all. 

Applicability to plastic, not just glass

Users of buildings or conservatories that use polycarbonate instead of glass for their windows or skylights can suffer from many of the same problems that lead Opalux customers to order from our range of conventional solar control window film – in short, excessive heat gain and glare.

It is therefore fortunate that we are also able to provide solar reflective films that have been manufactured with a specific adhesive, meaning they can be fitted to plastic without bubbling up.

Greater privacy

Not only does glazing through which external observers can easily see potentially serve to make a bad impression – for example, if your offices are often cluttered – but it could also have security implications if there are many expensive items inside that could tempt a prospective thief.

This is why the utmost daytime privacy may be a benefit that you would like your chosen solar control window film to achieve. An acclaimed internally applied Opalux film such as Reflective – Silver 20 (SO-20RS-iSR) could be perfect for ensuring this.

Less expenditure on cooling

If the rooms of your buildings reject excessive heat gain as a result of Opalux solar control window film having been installed, this also has the advantage of lowering your cooling costs.

Not having to depend so much on the air conditioning equipment at your premises also helps to reduce Climate Change Levy liability, thereby further lessening any unnecessary spending by your organisation.

Keeping the building’s occupants safe

As recent headlines have sadly given us cause to reflect on, severe heat gains are not only responsible for discomfort – they can also imperil a person’s health and safety.

You may therefore request the installation of solar control window film as a means of better ensuring your firm’s compliance with the Workplace (Health, Safety and Welfare) Regulations. This will also give you the peace of mind of knowing that your building’s users are as well-protected as possible.

Yes, glare can be a big problem in a conservatory, too

If you have only recently acquired your dream home conservatory, the last problem that you will want to have to experience is difficulty reading a book or a computer screen due to glare. However, this is an issue that arises with conservatories all too frequently, which is why you may wish to investigate the various forms of window film to reduce glare now on the market. 

Polycarbonate roofs can be affordable, but problematic

It’s unsurprising that conservatory roofs are often made from polycarbonate, given that this material is – after all – about three to four times less expensive than a glass roof. Unfortunately, though, polycarbonate roofs are just as vulnerable to glare as glass ones are, potentially spoiling your attempts to read, work or watch TV in your conservatory due to the bright sun obscuring your vision.

Thankfully, there are solutions on hand here at Opalux to give you vital relief from glare as a conservatory user. These include a translucent metallised film that is designed to be applied from the inside – known as Opalux Suncool SO-10SC-iBF – and a metallised silver solar protective film that doesn’t merely reduce heat and glare, but also provides one-way privacy during the day.

The latter of these films has the code SO-20RS-eBFSR, and incorporates the polycarbonate-friendly adhesive that you would expect from a product conceived with this type of conservatory roof in mind. It is highly effective simply as window film to reduce glare, delivering 81% glare reduction, but also offers so many more benefits, including up to 99% ultraviolet light (UV) filtering and a uniform outside appearance. Indeed, the film sports a silver reflective look from the outside, and a much less noticeable light tint when viewed within the conservatory.   

The ideal window films for a variety of requirements

While you may initially approach us with a need specifically for window film to reduce glare, we realise there may be various other things you would like your chosen product to do. This is why we are dedicated to supplying the most advanced and relevant selection of window films for a variety of requirements. Furthermore, we urge you to contact our technical team to benefit from the assistance that we can provide with the selection of the most appropriate solution.

Call us now on +44 (0)845 026 1125 or email, for all of the help that you could require to decide on and source suitable window film to reduce glare and heat – or for almost any other set of requirements.



Our solar reflective products have an excellent track record as glare reduction films

The decision to purchase solar reflective window film for your existing building or ongoing construction project may be made for any number of reasons. The reflective appearance of such films can be one key factor, not least in giving you exceptional daytime privacy. But the uniform look of these films can also be appealing simply from an aesthetic point of view, and then, there is their effectiveness in rejecting solar heat gain.

If, though, it is the reduction of glare that is the main result you wish to gain from any window film you purchase, you will also have much reason to be pleased with any solar reflective films you order from Opalux.

Whichever option you choose, exceptional glare reduction is guaranteed

Glare is a menace for many of those who own and use buildings for which window film may be purchased. It can be detrimental to comfort and productivity, making it a particular problem in commercial properties.

You may therefore be interested in buying relevant glare reduction films, such as Opalux’s Reflective – Silver 20 (SO-20RS-iSR) film that decreases glare by an astounding 82%, or the Reflective – Silver 35 (SO-35RS-iSR) film that can deliver 66% glare reduction. These are both internally applied solar reflective window films, with the range-topper – Reflective – Silver 50 (SO-50RS-iSR) – yielding an also-impressive 47% glare reduction.

These films do, of course, vary in other respects, with the Silver 50 film, for example, transmitting somewhat more solar energy through the glass than Silver 20. Nonetheless, they also have certain characteristics in common, such as their quick, retro-fit installation process and rejection of up to 99% of ultra-violet (UV) rays.

We have great external reflective films for lessening glare, too

In some circumstances, it may be necessary to apply film to the outside of your building’s glazing instead of the inside, such as if internal access is not possible. This is why it is fortunate that if you are seeking a combination of a solar reflective appearance and suitability for external application, we have several options – External Reflective – Silver 20 (SO-20RS-eSR) and External Reflective – Silver 35 (SO-35RS-eSR) – that bring exceptional results.

Such results include high levels of glare reduction that mirror the performance achieved by the interior-applied versions of these two films.

Don’t forget, too, that we can even give you External Reflective Silver 20 for Polycarbonate (SO-20RS-eBFSR) film, which is perfect for many polycarbonate substrates such as conservatory roofs, and delivers 81% less glare. For all kinds of solar reflective glare reduction films, then, Opalux is the only brand to which your organisation ever needs to turn. 

Enhanced solar protection window film is available to ward off harmful UV

The havoc that ultraviolet (UV) light from the sun can cause in all manner of buildings should never be underestimated. Even premises where there may not seem to be much in need of protection can suffer from excessive UV, which is responsible for warping and cracking wood, fading the colours of fabrics and even damaging artworks over time.

Then, there are the rather more sensitive and specialised settings in which solar protection window film may be needed, such as museums and retail stores.

This is why it is so fortunate that we are able to supply the highest standard of enhanced UV protection film here at Opalux – but here are some of the things that you should know before ordering.

Going beyond standard UV protection

One of the great advantages of choosing Opalux for your own premises’ polyester window film is the fact that all such products we manufacture contain UV absorbers rendering them capable of blocking up to 99% of UV rays in the 300 to 380-nanometer range of the solar spectrum.

However, there may also be circumstances in which you require enhanced UV protection covering up to 400 nanometers and beyond. This is precisely what is provided by our Specialist UV Control – Clear film (SO-CLUV-iSR), which surpasses the requirements of leading conservation experts who have researched ultraviolet filters.

This film is not only able to be installed quickly, but is also scratch-resistant and depended on for the protection of exhibits, displays and furnishings from UV radiation.

But it is our UV Control – Amber 81 solar protection window film (SO-AMUV-iSR) that is even more impressive, its amber colour signalling its exceptional blocking capability. Like the SO-CLUV-iSR film, it exceeds the standard museum test requirements for low UV transmission and colour distortion. But it goes even further than this, providing excellent blocking up to 400 nanometers and keeping transmissions below 10% right through to 500 nanometers.

Ask us for help with choosing the right specialist film for you

Whatever the set of circumstances that might lead you to consider our enhanced UV solar protection window film, you should always consult the Opalux technical department before making your choice, so that you can be guided to the product that suits your every need.

It may be that you require not just a quote for such window film, but also a deeper discussion and site visit from an Opalux approved dealer. So for the utmost peace of mind, don’t hesitate to call us on 0845 026 1125, or fill in and submit our straightforward online contact form
