Solar Solve can supply window films that is used to help comply with current government guidelines for bomb-blast protection
Safety and security films are designed to make glass safer, both by strengthening it against breakage and helping hold in place dangerous shards of shattered glass in situations where breakage does occur for whatever reason.
Clear safety and security films offer a quick retro-fit solution avoiding costly and disruptive replacement of glass.
They are optically clear and invisible when installed, and being scratch resistant, are suitable for most non-abrasive window cleaning methods.
They also screen out 99% of UV radiation reducing fading and deterioration of soft furnishings and other vulnerable items.
Tested and certified to EN 12600 Class 1B1, 200-micron safety film is used to help comply with current government guidelines for bomb-blast protection. Multi-laminate safety and security film is now widely used by government agencies as well as many commercial organisations concerned to address the real corporate risk of bomb-blast, or industrial explosion.
Safety and security film can be purchased in either half or full rolls.
Not all films are suitable for all glass. The absorptance of the glass and the film, the size of the pane, the thickness of the glass and the construction of the window should be considered in terms of single pane, insulated glass, treated (with a low-emissivity coating), laminated or toughened.
Advice on the appropriate selection of film for the glass is vital to ensure that the glass does not crack as a result of thermal stress. However, it is possible that a pane of glass may break subsequent to the application of an appropriate film, because the glass pane has been damaged during the glazing of the window, or as a result of movement of the building or other physical stresses that are not apparent at the time of the film application.
The chances of glass breakage occurring subsequent to the application of film is very small. However breakage can occur and it is impossible to predict the edge condition of the glass without removing it from the frame – an approach that is not practical.
Adhesive window film should only be applied to flat glass. It should never be applied to polycarbonate (plastic). We do not recommend that metalized (reflective) window film is applied to wired glass, double glazed units or highly tinted glass as thermal cracking can occur.
What is Adhesive Window Film?
Adhesive window films are constructed from a multi-lamination of micro-thin polyester. They also have a scratch resistant coating (SR) to protect the film surface and enhance durability (except films for external application).
Most films are applied to the interior surface of a glass window in a home, commercial building, or vehicle. They have a scratch resistant coating on the outer surface to protect the film. Window film is specifically designed to protect windows from heat caused by sunlight, as well as IR and UV light. To do this, dyes and metals are layered between layers of polyester film which are bonded together. The type, amount, and quality of the dyes and metals used in the manufacturing process determine the quality, durability shade, colour, heat absorption, UV reflection, security, etc. of the finished product.
Drying or ‘Curing Out’ Time
The performance of window film is not fully effective immediately. A ‘curing out’ period should always be allowed of up to 30 days after installation when the remaining application solution between the film and glass evaporates. During this period the film is still performing to its full solar control and safety capabilities. As the film begins to dry out, it is common to see bubbles, haze, streaks, and other visual defects in the film as it cures. This is completely normal, and these will disappear as the film dries out.
Firm ‘squeegeeing’ is vital to reduce or eliminate a ‘clouding’ effect caused by water condensation during the ‘curing’ stage. If clouding occurs it should only take a few days to clear completely. Drying conditions, however, should be adequate, including room temperature and ventilation, otherwise clouding can remain for a longer time.
A ‘light line’ is a gap left around the edge of the window film (approx. 2 – 3mm) after application to the glass. It ensures that the solution used to apply the film can be more easily removed when ‘squeegeeing’, and avoids the potential for water and suspended dirt particles to move under the film by capillary action. It also ensures that the installed film does not touch the frame margin which could lead to lifting and peeling of the film.
Tiny water bubbles between the film and glass are normal. About 10 – 15% of the moisture stays between the glass and film immediately after installation. This moisture will disappear through condensation as the film is porous. Bubbles that do not disappear can be removed by bursting with a fine needle or sharp utility knife.
‘Inclusions’ are small particles of dust trapped between the film and the glass and should be removed by peeling back the film from the glass and flushing out using water, before the adhesive begins to take effect.
Window films filter out over 99% of UV rays, reducing the main factor in fading. However, additional factors such as solar heat, visible light, humidity, and the presence or absence of chemical vapors also contribute to fading. Therefore, the greatest protection from fading is offered by tinted or metalized window films that reject larger levels of heat and visible light, in addition to UV.
Maintenance / Cleaning
The cleaning process for a filmed window is similar to unfilmed glass. Before cleaning make sure that the film has fully cured. We recommend waiting 30 days before cleaning after the film is installed. Use a soft clean cloth, soft paper towel or clean synthetic sponge that is NOT abrasive. Soapy water or a normal glass cleaning solution which contains no abrasives is fine to use. Dry with a soft clean cloth.
All films are covered by a manufacturer’s 5-year Guarantee against peeling, cracking, demetalization and delamination.
