CLERA WINDOWS + DOORS · PATIO DOORS GUIDE
A patio door is a large glass door that connects an indoor living space to an outdoor area, such as a deck, patio, or backyard. Patio doors are known for their floor-to-ceiling glass panels, which maximize natural light and provide an unobstructed view of the outdoors.
The two standard types of patio doors include sliding patio doors, where one panel glides horizontally along a track, and French patio doors, which open like traditional doors with two panels that swing on hinges.
In Canada, patio doors must be built to withstand significant temperature variations, and energy efficiency is a key performance factor when selecting a replacement unit. Look for multi-chamber vinyl frames, triple-pane glass, Low-E coatings, and ENERGY STAR® Canada certification.
Why Clera? Clera patio doors are manufactured in Canada and engineered specifically for the thermal demands of Canadian winters, with multi-chamber vinyl frames and advanced glass packages available.
