If you are in the market for a dedicated film to apply to your building’s windows – perhaps because of concerns about winter glare, but also potentially heat gain – you might have presumed you would need to buy a film that is applied to the inside surface of your property’s glass, rather than to the outside.
After all, if glare reduction and heat control films are to be installed on the external surface of a building’s windows, there is an obvious thing they need to do: stand up to the outdoor elements.
In some circumstances, it might not be possible or easy to install a window film from the inside of the given property. This may be due to the internal surface of the windows not being very accessible, or because of the type of glass (as in the case of certain double or triple glazing, or laminated, Georgian-wired, heavy tinted windows).
Introducing Opalux-branded external reflective window films
If you already have some glare reduction or heat control films that are designed for internal application, and you’re considering installing them to the external surfaces of your building, we’re afraid this isn’t recommended. Such internal film hasn’t been designed and made to stand up to punishing outdoor weather conditions and ultraviolet (UV) rays.
This brings us onto the external reflective window films that we make available from the renowned Opalux brand. These films are produced with outdoor weather specifically in mind, so you can count on them providing years of longevity once installed.
No less importantly, however, the window films in this range have excellent credentials when it comes to driving down glare and rejecting heat gain, whatever the time of year.
At the time of us writing this, there are three films in this particular range, including:
• External Grey/Silver 10
Of the three films, this dual reflective film is the most effective at reducing glare, bringing it down by a whopping 91%. This 60-micron film rejects 85% of total solar energy, which helps make it an excellent choice for repelling severe solar heat gains.
If the achievement of one-way privacy is a big priority for you, External Grey/Silver 10 will produce this effect to a greater extent than conventional reflective films. Its effectiveness at hindering vision into a property helps bolster security, too.
• External Silver 20 (7 years)
If you’re attracted to the notion of investing in an externally applied window film that reduces glare by 82% and rejects 78% total solar energy, while providing a uniform outside appearance and daytime one-way privacy, this could be an excellent choice of product. Such characteristics enable this film to alleviate the discomfort that high levels of heat and glare cause.
This film comes with a seven-year warranty if it is applied to vertical glass, and a warranty of up to four years if installed on a sloping surface. Please note that this warranty will only be valid if installed by an approved installer; please consult the full warranty terms and conditions for further information.
• External Silver 35
When you are comparing externally applicable glare reduction and heat control films, you might be particularly anxious to make sure that – in addition to providing good solar heat and glare rejection – your chosen film provides good vision in both directions through the glass.
If this sounds like your priority list for an external window film, Opalux’s 70-micron Reflective Silver 35 product could be the perfect choice. This film transmits 30% of visible light, and reduces glare by a still very significant 66%.
