Yes. New homes in the GTA are built to code, but building code does not require high-performance glass. Most new builds use standard double-pane windows that meet minimum energy standards but still let in significant solar heat and UV radiation. Window film closes the gap between what your builder installed and what your home actually needs.
This is especially relevant for new builds in Markham, Vaughan, Brampton, and Mississauga where homes feature large windows and open-concept layouts designed to maximize natural light. That same light brings heat, UV damage, and privacy issues that the builder did not solve.
What New Homes Are Missing
Builders install windows that meet Ontario Building Code requirements. These windows provide basic insulation and weather sealing, but they do not block significant amounts of solar heat or UV radiation. Standard Low-E coatings on new windows block some UV but typically reject only 25 to 40 percent of solar heat. Professional solar window film blocks up to 80 percent.
The result is new homes that look beautiful but overheat in summer, have fading hardwood floors within 2 to 3 years, and cost more to cool than they should.
Will Film Void My New Window Warranty?
This is the number one concern from new homeowners. In most cases, professional-grade window film does not void window warranties when installed correctly with compatible products. At Proferred Film Solutions, we check the glass type and manufacturer specifications before recommending any film. We use Madico and SolarGard products that have established compatibility with all major window manufacturers.
If your builder installed a specific brand of window, we verify compatibility before any installation.
Best Time to Install Film on a New Home
The ideal time is within the first year of moving in, before UV damage starts accumulating on your floors and furniture. Many homeowners wait until they notice fading or heat problems, but by then the damage is already done. Installing film early protects your interior investments from day one.
What New Homeowners in the GTA Are Installing
Based on our experience in Markham, Vaughan, and across the GTA, new homeowners most commonly install solar film on south and west-facing windows (the biggest heat problem), UV protection film throughout the home to protect hardwood and furniture, and privacy film on ground-floor bathrooms and street-facing bedrooms.
