Frosted window films can provide so much more than privacy

The most obvious application of a window film with a frosted effect may be to enhance privacy, but it is easy to overlook the vast range of ways in which the very best such window films make this possible – as well as what other purposes our industry-leading products in this category can serve.

This much is demonstrated by the extensive stock of frosted window films that we can offer at present from no fewer than three of the most respected brands in the window film world today: Opalux, Mactac and 3M.

We can cater to your privacy requirements, without compromise elsewhere

One of the greatest concerns that both specifiers and end-users can frequently have when they are considering investing in privacy screening films, is ensuring that privacy can be provided at the same time as allowing a good level of natural light through the window.

Thankfully, this is a priority that can be addressed by Opalux’s present translucent frosted window films such as the Fine Acid Etch Bronze, Fine Acid Etch Smoke or Fine Acid Etch White film. The latter is an especially popular choice of frost film for rooms where 24-hour total privacy is required, representing a more flexible alternative to privacy glass over a building’s lifetime.

Alternatively, you may take the greatest interest in our MACal frosted window films. These particular products deliver an exceptional performance both indoors and outdoors, and may be your choice if you wish to decorate your windows or glass decor with an etched, frosted or sandblasted effect. Two matt finishes are available for these acclaimed films: frosted and dusted.

Finally, we would also urge you not to overlook 3M’s highly respected glass films if you are interested in creating unique ‘special effects’ on your windows. Whether you opt for the dusted or frosted varieties of the 3M window films we offer in this category, you can look forward to not only superb two-way privacy, but also sustained high light levels, quick retro-fit installation and the scope to incorporate graphics into the film, as could help to perpetuate your brand’s corporate identity.

Could any of these frosted window films – or the other privacy, solar control or safety-oriented products elsewhere in our range – be the right ones for your own intended application?

Whatever your priorities, by calling Stockfilms today on 020 8441 0449, you can receive the advice and guidance that you require to make the most informed choice at the first attempt, and are even welcome to request free A4 samples before committing to any purchase. Then, we will be delighted to present you with the most competitive quote for the film that ideally suits your needs.




Make sure you only purchase heat control films that also make perfect aesthetic sense

It doesn’t exactly surprise us here at Stockfilms that we receive so many enquiries about heat control films at this time of year, when temperatures are at their most elevated. However, it’s also vital that if you are a specifier or end-user looking to invest in such window films, you are aware of the other requirements these products must fulfil in the context of your particular application.

After all, it is during this sunny season that your buildings will be shown off to best advantage – but not so much if you fail to select window films that help to make such a great impression.

Effectiveness at reducing heat gain shouldn’t be your only requirement from window film

You may take an interest in our heat control films in the first place due to how they can help to reject the excessive heat gain that could make your buildings a less-than-pleasurable place for your occupants to be. Sure enough, we offer an extensive variety of window films that can repel a large proportion of solar energy, at the same time as significantly reducing glare and transmitting a level of visible light that suits the practical requirements you have for the given space.

There is a significant cosmetic difference, however, between our reflective window films and such options as our low mirror, tinted, coloured and specialist heat control films that cater to a variety of aesthetic priorities.

As with our reflective window films, we offer low mirror window films in both internal and external variants, with these products being an excellent choice if a more neutral tinted look is desired, at the same time as a good level of heat and glare control. We can also provide non-metallised tinted window films in a range of shades, which enables varying levels of daytime privacy to be achieved.

You might also turn to Stockfilms for coloured window films that enhance the decorative appeal of any glass while achieving optimal heat and glare rejection. Or perhaps your given application would best suit a Clear Heat Control film (SO-70IR-iSR) that very much lives up to its name, being almost invisible in appearance, but still delivering a good heat control performance?

Don’t accept anything less than industry-leading heat control films

With architectural and automotive window films available in our stock to cater to every visual and practical requirement here at Stockfilms, there’s no need for you to look further for proven, sophisticated and cost-effective heat control films.

Give our friendly and receptive customer service team a call today on 020 8441 0449, and we’ll be able to guide you in the direction of the most suitable window film for your particular requirements, followed by the best possible quote.






You’ve got plenty of options for internally applied low mirror window films

Deciding between different window films intended to enhance solar heat and glare control isn’t just about comparing the performance statistics for these products. That’s because, whether you are an end-user or specifier, aesthetic considerations will always come into play, and it is here where our low mirror window films for internal application can truly prove their worth.

As synonymous as window films often are with a highly reflective appearance, this isn’t always a desirable aesthetic for many of our customers, who may nonetheless still desire a good level of solar heat and glare control in whatever product they select.

So, what do these films offer other than low reflectance?

Whether you are interested in internally applied low mirror window film mostly on account of its low visual impact or its performance, it is important to carefully compare the relevant figures for these products, given that they don’t offer identical levels of solar heat and glare control.

Our Bronze 20 (SO-20SB-iSR) film, for example, sports a muted bronze hue from both inside and outside the building to which it is applied, and only transits 20% of visible light, while reducing glare by 77% and rejecting 75% of total solar energy. This compares to the Bronze 35 (SO-35SB-iSR) product for which the equivalent figures are 35%, 53% and 55% respectively.

One can observe a similar trend across our assortment of Neutral Grey low mirror internal window films. This range begins with a Neutral Grey 20 (SO-20NG-iSR) film that, in accordance with its name, allows the transmission of 20% of visible light, while achieving 80% glare reduction and rejecting 70% in total solar energy. The Neutral Grey 50 (SO-50NG-iSR) product at the other end of this range, meanwhile, enables 50% of visible light to be transmitted; it also lowers glare by 45% and rejects 50% of total solar energy.

Finally, our trade customers are also able to choose between Cool Grey 20 (TSO-20CG-iSR), Cool Grey 35 (TSO-35CG-iSR) and Cool Grey 50 (TSO-50NG-iSR) films; the former of these rejects a greater proportion of total solar energy, and also achieves the most pronounced level of glare reduction.

We can guide you towards the most suitable choice for solar heat and glare control

We realise here at Stockfilms that our customers frequently begin their search for window film with widely varying applications, circumstances and requirements in mind, thereby increasing the importance of them receiving the best possible advice before committing to a purchase.

Such advice is precisely what the seasoned technicians in our team are excellently qualified to provide, alongside the most comprehensive and competitive quote for your needs. Simply call 020 8441 0449 today for the best-tailored support and pricing information. 

Sometimes, shade material may be better suited to your needs than window film

Are you seeking a solution that will enable you to allow natural light into a room, but not the excessive heat and distracting glare so often accompanying it? In which case, you may be dissatisfied with a situation in which the occupants of the given space have to continually adjust fabric shades on the windows during the day – which may lead you to look into window film.

It isn’t always conventional window film that represents the best answer to such a quandary, though, as is perhaps especially well-demonstrated by our shade material. We give you various options for shade material, which is also a great choice for situations where there is sometimes a need for privacy, and sometimes not.

Which varieties of shade material can we offer at present?

At the time of typing, Stockfilms offers no fewer than four different shade material products: bronze/bronze, bronze/silver, grey/silver and grey/silver/grey.

The specifications of these shade material options are not identical, so it’s well worth carefully considering these differences before making your selection. It is our grey/silver and grey/silver/grey products that offer the most impressive glare reduction, for instance, in excess of 90%.

Of these two films, it is the grey/silver/grey option that is the thickest at 100 microns, this product incorporating an additional layer of silver metallised polyester between the films to maximise heat rejection while still ensuring a low-impact appearance to the glass.

This same extra layer is also present in the 100-micron bronze/bronze shade material, which is bronze in colour to ensure a neutral look in the room. This particular film provides good solar heat and glare control, as well as full or partial privacy, protection against ultraviolet (UV) rays to minimise the fading of interior furnishings, and good visibility from the inside looking out.

Finally, we can also offer a 75-micron bronze/silver film that is silver to the exterior face, thereby helping to ward off prying eyes from outside. The silver also reflects away more heat than a more neutral appearance would make possible.

Allow us to help you in selecting the right window film

As you can see, different window film or shade material options suit different priorities, so it’s important to be sure about your own pressing needs when you come to specify one of these products. Call the Stockfilms team today on 020 8441 0449, and we’ll be able to assist you in choosing the product in our range that will best answer those needs, and at the right price.

Coloured vinyls from us are just the thing for injecting creativity into windows

We will always be proud here at Stockfilms of the exceedingly wide range of applications for which our window films can be used. However, some of our products are certainly better known than others, with one of our perhaps unjustly overlooked ranges surely being our selection of coloured vinyls – of which transparent, translucent and opaque versions are available.

Why would you wish to buy these distinctive window films?

Naturally, the exact settings in which one may be inclined to install window films like these may vary according to the variant that is selected.

As one might expect, our transparent coloured vinyls are a popular choice among those specifiers and end-users that are interested in creatively decorating windows without compromising the ability to see through them. We are pleased to offer MACcrystal 8400 vinyls that are transparent, coloured and glossy; no fewer than 16 different colours are available for them, and they are often used in the manufacture of illuminated signs made from opaline acrylic sheets.

As aforementioned, though, translucent coloured vinyl window films are also available, and as their name indicates, they do still allow the passage of plenty of natural light into a room; however, they also have a role in enhancing privacy. While our MACal 9700 vinyls in this category usually appear translucent when backlit, they tend to look opaque when they aren’t illuminated.

If you want to go opaque, go opaque...

Finally, opaque coloured vinyl is another speciality of ours – or more specifically, white, black and coloured variants of our MACal 9800 Pro window film. Customers can choose between a matt or gloss finish for the black or white versions of this product, whereas if one opts for the coloured film, some 99 hues are available.

All of these opaque 66-micron window films are designed for long-term interior and exterior graphic applications where high performance is expected.

Sure enough, they incorporate a specially formulated acrylic adhesive to enhance their durability, and can be expected to last for between five and seven years, whether they are used for equipment identification, fleet marking or window graphics.

It couldn’t be simpler to enquire to our professionals

Would you appreciate further advice and guidance so that you can be sure of selecting the window films from our extensive online range that will best serve your intended purposes? If so, not only are we able to help you in this regard, but we always recommend, in any case, that our customers first get in touch with our technical department before placing any order.

Simply call 020 8441 0449 today to talk through your priorities for your next window film purchase, and to request a great-value quote from one of the industry’s most trusted wholesale distributors.



Opalux’s Mani-Fest™ products can be invaluable for boosting safety

Many of us have had moments of colliding into glass due to not even realising it is there, but this isn’t merely embarrassing – it could actually be a health and safety risk, and indeed, a legal one.

That’s because there are regulations that specifically call for large uninterrupted areas of glazing to be marked. The Workplace (Health, Safety & Welfare) Regulations 1992 state: “Every window or other transparent or translucent surface in a wall or partition... door or gate shall, where necessary for reasons of health or safety... be appropriately marked or incorporate features so as, in either case, to make it apparent”.

Whether or not you were aware of this regulation, window films exist that can address such a requirement. Here at Stockfilms, we can offer Opalux’s acclaimed Mani-Fest™ Glazing Manifestations in Opal Frost, which comply with the regulations in a neat and unobtrusive way.

What else should you know about Opalux’s glazing manifestations?

These window films come in the form of 50mm ‘dots’ or ‘squares’ with 50mm or 100mm spaces. From a company’s point of view, they just don’t provide the necessary safety marking, but also help the firm to discreetly reinforce its visual identity to anyone using the space in question.

Opalux Mani-Fest™ Glazing Manifestations are also extremely convenient, being provided on a 50-metre continuous roll that enables the installer to apply the film on as many window panels as required, while the small, compact box makes it easy to carry around. The box also incorporates a re-sealable lid, giving the user further assurance that the manifestations will remain in good condition for whenever they’re next needed.

Any contractor using these glazing manifestations should also be appreciative of the paper application tape that allows water to permeate it, thereby making these window films easier to work with when they are being applied to the glass. The lack of artwork, plotter cutting, weeding or masking needed when one purchases and applies these film products also frees up machines and operators for more rewarding work. 

Contact us today about these fuss-free window films

Why look elsewhere for easy-to-use and effective manifestation products for any of a wide range of settings? Phone the Stockfilms team today on 020 8441 0449 to discuss the window films we can supply in accordance with your business’s most demanding requirements.

We can bring you the right window film solutions for the better management of light

While there is a broad range of applications that the leading window film products can have, you may be especially conscious at this time of year of the remarkable quality of the natural light that filters into your premises – or for that matter, its undesirability in certain circumstances.

Thankfully, alongside our established selection of solar control films that we have long been pleased to offer here at Stockfilms for superior heat rejection and glare reduction, we can also bring our customers the benefit of a wide range of sophisticated light management films.

What options may appeal to you across this in-demand range?

Whether you are seeking to block out, diffuse or reduce light as an end-user or specifier, Stockfilms can supply the window film to suit.

If it is light reduction that you are interested in achieving at a given site, for example, our non-reflective and non-metallised Slate films provide an excellent solution for better controlling how much light is permitted to enter a room. They achieve this without the need for a mirrored external appearance, as is so often the result of the installation of window film.

Instead, our Slate films can be specified in a range of shades for the tinting of clear glass, with the lighter options tending to be used to match the appearance of existing tinted glass.

Renowned blockout and diffuser products are also available

As we mentioned above, Light Blockout window film can also be purchased from us for when a completely opaque appearance is desired to ensure 24-hour privacy. You may apply such window film to glass partitions, for instance, where there are shelves or other items close to the glass that you do not wish to be seen.

Options in this blockout category include 3mil Blackout and 3mil Whiteout films, which both block all vision, except that the latter allows a small percentage of natural light through the glass. Black Light Blockout and White Light Blockout films are also available for controlling light flow in internally illuminated signs.

Finally, 30% and 60% Light Diffuser Films are also present in our stock; these are mainly used for fluorescent lighting applications, and still provide for the transmission of a high level of light. These 70-micron films can be applied both internally and externally, enable better light diffusion and uniformity in illuminated signs, and provide a white uniform appearance in both reflective and transmitted light.

We’re always at the other end of the phone

Are you still struggling to decide on the light management films that would best serve your own requirements as a specifier or end-user, or would you simply appreciate some more advice?

Call the Stockfilms customer service team now on 020 8441 0449, and you will be able to receive such advice and guidance, as well as to request free A4 samples and receive a competitive quote.

What are the best ways to extend the lifespan of your window film?

There’s much more to ensuring that your fitted window film lasts for longer than simply selecting the most appropriate brand and type of window film to begin with – although these are undoubtedly crucial elements.

As it happens, there are various ways to bolster your window film’s longevity at every stage of its useful life.

Ensure your chosen window film is up to the job

While we take great pride in our exceptionally engineered window films here at Stockfilms, the fact remains that different window film options are geared towards different needs. This inevitably impacts on the amount of time for which you can expect a given installed window film to last.

Quality of design and manufacture will doubtless affect the likely operational lifespan of a particular window film, but so will the conditions to which it is subjected.

Window film that is continually exposed to the elements is especially vulnerable to rapid deterioration, which is why it is so crucial to select dedicated external window film for such settings.

We offer internal and external Silver 20 window films, for instance, which both provide excellent solar heat and glare rejection. However, the latter film is of a weather-resistant construction incorporating additional UV barriers to guard against the potentially ravaging effects of constant sunshine, and also uses a strong waterproof adhesive.

Purchasers of window film are also advised to pay close attention to the warranty attached to the given product that they are considering. Referring back to the Silver 20 films, for instance, the internal version comes with a 10-year warranty, compared to the external film’s seven years.

Are you installing and maintaining your window film appropriately?

As we have detailed in our Frequently Asked Questions (FAQs) section, we recommend that window film is only fitted by a professional installer, not least given the ease with which it can be damaged if an inexperienced amateur attempts to take on this task.

However, the right cleaning and care of your window film, as we have explained on the relevant page of our site, can also make a major difference to the product’s lifespan.

The cleaning of your film, for example, will bring the best results if you wait for 30 days after installation. Nor should brushes, coarse paper towels, pure ammonia or industrial strength cleaners be used. Instead, only a soft clean cloth should be used for both washing and drying.

Ask our technical staff any maintenance questions

If you are in any doubt about the steps that you should be taking to keep your window film in good condition – and therefore delivering the best attainable results – for longer, you are always welcome to call the Stockfilms customer service team on 020 8441 0449.

We can advise you on whether you are taking the right care of your window film – and even whether you are using the right window film on your building’s glass at all.

Can architectural window film be installed on a car?

It is understandable why many of those investigating options for automotive window films find themselves wondering: “Can architectural window film be installed on a car?”

After all, the broad purposes of automotive and architectural window films tend to be very similar. Whether you are looking to purchase window film to be applied to a building or a vehicle, you are likely to be interested in a product that can reduce distracting glare for occupants, while also preventing excessive heat gain and perhaps enhancing security and aesthetics, too.

However, the bottom line is that architectural window films are not recommended for application to the glass of an automobile window, and there are various good reasons for this.

The two popular types of window film have several vital differences

While the general benefits of automotive and architectural window film tend to be much the same, various technical differences between the two are likely to mean you will be wasting considerable time and money if you attempt to apply architectural window film to a car.

One key factor is that automotive window films are specially designed to shrink onto the curved glass that constitutes the typical vehicle’s windows. The adhesive of such film attaches itself to a vehicle’s glass in such a way that a smooth, seamless and wrinkle-free appearance can be achieved.

You cannot expect such a professional finish to be attained if you attempt to apply an architectural window film to your car window. This is largely due to the non-shrinking nature of architectural window films, which are usually applied to the flat surfaces of home or office windows.

It is also crucial to bear in mind the need for visibility through a vehicle’s window when you are looking to install a window film on a car. Some architectural window films are designed to reduce visibility through the glass to an extent that would pose a danger to drivers and other road users and pedestrians alike, if this film was applied to the window of a car.

Above all else, you should always have your film professionally installed

The question “can architectural window film be installed on a car?” is not the only one that must be answered. This is because, even if appropriate window film is selected for a given application, it must also be installed correctly in order to provide the best possible results.

It is for this reason, as well as the ease with which window films can be damaged if they are improperly handled, that we always recommend a professional installer fits any given window film – whether intended for automotive or architectural use.

Call the Stockfilms customer service team on 020 8441 0449 today, and we can advise you as to the most suitable window films for your desired application. Indeed, we can also provide free A4 samples of all of our products on request.

Can window film be used on low-E windows?

While low-emissivity glass – or low-E glass as it is commonly described – can be a highly invaluable form of glass for preventing heat from escaping through a building’s windows, you may understandably have other needs that could be served by an appropriate window film.

A low-E coating on glass, after all, may be excellent for boosting a household or business’s  energy efficiency while reducing monthly bills and minimising the building’s carbon footprint, but it doesn’t address other needs that occupants may have – for example, to reduce glare or enhance the safety of the windows.

This is where the right window film can come in, which may lead you to ask the question: “can window film be used on low-E windows?”

The short answer is yes, it can be... but there are also some other factors to bear in mind.

The type of low-E coating makes a big difference

The biggest question is not so much whether window film can be used on low-E windows, but instead whether it should be.

How you answer this question for your own building will depend on such factors as the type of low-E surface used on your glass, as well as where the low-E surface is located in the window system, and what effects you desire from your window film in terms of minimising heat gain, reducing heat loss or other potential benefits.

Two basic types of low-E window surfacing exist. One of these is a conductive coating that is applied to glass during its manufacture, while the other is a more complex arrangement of multiple layers of metals and conductive coatings. This latter type is only deposited on the glass once it has been made.

The first type of low-E glass can help slightly in reducing the amount of heat that escapes from a building, but isn’t very effective at keeping heat levels low in a building in hotter conditions. The second type, though, is renowned at reducing heat within a building in this way, while also minimising how much heat is lost from a building through its windows.

If, then, you are buying window film with the specific intention of reducing heat gain within a building, it could work very well on low-E glass of the first, less effective type.

But location is a major factor, too 

However, the wisdom of using window film on low-E glass will also be largely determined by the exact location of the low-E surface in the window system.

For example, if the low-E coating is on the room-side surface of the innermost pane of glass, using window film may make the low-E glass less effective at reducing the amount of heat lost from the building, or eliminate this benefit altogether. This might not be such a great concern, however, if your chosen window film also offers strong heat loss reduction.

It is much more common, though, for low-E window systems to consist of double pane windows in which the low-E surface faces the air space between the panes. If this is the case for your own low-E windows, you will be able to install window film without the glass’s existing heat loss reduction benefit being eliminated.

The specific form of window film that you should select for your building will hinge on factors like the above and the other purposes that you intend the window film to serve – for instance, to reduce glare or limit heat gain in the building. 

If you are yet to have low-E windows installed in the given building, however, or if you desire a low-E effect for existing windows, we are pleased to be able to offer dedicated low-E window film that offers a host of other benefits alongside the traditional greater retention of heat within a room.

So, can window film be used on low-E windows? Yes it can be, but you will need to take into account all manner of practical factors and the intended benefits when you are looking to select a window film that can be depended on to deliver worthwhile results.
