Frequently Asked Questions

A heat control window film is a thin, multi-layered film applied to glass that blocks infrared radiation, which is the primary cause of heat buildup inside a vehicle. Unlike basic tinted films, heat control films maintain a cooler interior without significantly reducing visibility. They also block up to 99% of UV rays, protecting occupants and preventing interior fading.

Clean the glass thoroughly before beginning. Prepare a soapy water solution at a ratio of 1:10 soap to water in a spray bottle. Cut the film slightly larger than the window. Peel the backing liner and spray both the glass and the adhesive side with the solution. Align the film on the clean glass, press down gradually, and use a squeegee to remove all air and water from the centre outward. Trim any excess film and allow 3 to 5 days for complete curing. Professional installation is strongly recommended for windshields.

For small bubbles, use a soft squeegee or a microfiber-wrapped card to push them toward the nearest edge. For lifting edges, apply a small amount of mounting solution beneath the film and press firmly back into place. If the film exhibits widespread peeling, extensive bubbling, or discolouration, complete removal and replacement is the recommended course of action. To avoid such incidents use Cosmo Sunshield.

Nano-ceramic window films offer the best heat control performance. When evaluating options, look for a high Total Solar Energy Rejected (TSER) percentage and strong infrared rejection capability. Cosmo Sunshield Ultra Cool Series is a notable option, with variants ranging from the 7090 for bright interiors to the 5095 and 1595 for progressively higher heat rejection and privacy
