What do VLT, TSER, IRR UVR in the specifications mean?
VLT—Visible Light Transmittance
This is the amount of visible light that passes through window films, brightening up the interior.
TSER—Total Solar Energy Rejection
Total solar energy rejected by the film by either reflecting it away or absorbing it and reradiating it back outwards. Solar energy includes infrared, visible, and ultraviolet light.
Infrared light is the biggest contributor to what we feel as heat. This measures how much of that heat is either reflected or reradiated outwards, resulting in a more comfortable interior.
Ultraviolet light is the biggest contributor to material degradation, such as fading paint, aging leather, and even skin cancer. Reducing ultraviolet light would result in greatly improved visual longevity for interior furnishings, and a much healthier interior environment, too.
These four measurements are the most crucial figures to determine a window film’s efficiency and effectiveness, and we test our films to make sure they meet our minimum standards.
How are films installed?
For best results, we recommend that our professional film specialists install Sunbloc window films. DIY installations are possible but difficult, and inconsistencies might arise.
The first step is preparation. Our trained personnel will measure your windowpanes, allowing us to send a price quotation within a few days. If acceptable, other install preparations would be made, with a few assessments such as the need for protective covering and scaffolding in the area.
Next, we would thoroughly clean the glass before actual installation. A solution would then be sprayed onto the surface to allow easier film alignment, and, upon removing the film’s release liner, we stick the film onto the glass and align it as needed. Using a squeegee, we remove excess solution and dry the edges, and there we have it!
Do note that we only install on interior surfaces, and not on the outside. Direct exposure to the sun can cause immediate color fading, and, in the case of the latter, heat trapped by films could damage glass. We also do not install on non-glass surfaces such as polycarbonate and acrylic, as well as uneven or damaged surfaces. Should clients insist, no warranty would be given on the installation.
How do I take care of my window films?
After a few days of curing, and anytime after, you can easily clean panes with window films installed in the same manner you would normally clean glass. Water is fine, as well as most glass cleaners, as long as they are ammonia-free. Spray the cleaner on and gently wipe with a soft cloth. Use of abrasive materials (brushes, but why would you?) is not recommended.
