At Thermo-Bilt, we use a better glass for better replacement window and door products.

High-performance, energy-efficient vinyl windows and doors in Toronto are today’s standard, but we always raise the bar to remain first in the glass. Our replacement windows and doors are built with glass from Cardinal, a tech-forward manufacturer that’s glass science obsessed. Through superior glass engineering and rigorous testing, they’ve developed layered glass that lasts longerstays cleaner, and maximizes thermal performance.
