About Vinyltek Windows
Not all new or replacement windows and doors are created equal. When you choose Vinyltek, you're selecting windows and doors that are Canadian made, ENERGY STAR rated, engineered with leading window glass technology and all backed by the best customer service in the industry.
Thermoproof Manufacturing has been making windows, patio doors and skylights on Vancouver Island for over 30 years. When manufacturing our products, we use only high quality pure vinyl that resists fading, chipping or peeling and never needs painting
