Ottawa’s Leader in High-Performance Windows
High-performance windows add thermal protection, reducing annual heating and cooling bills, and lowering the peak heating and cooling loads. Low-E4 glass employs a hermetically sealed system for optimum insulation from heat, cold and sound. This is caused by low-conductivity argon gas that separates the two panes of glass. Compared to ordinary dual pane glass, Low-E4 glass is significantly more energy efficient in summer and in winter.
Some other benefits include:
- High-performance windows help to reduce unwanted heat gain without sacrificing light penetration.
- High-performance windows can influence the type and intensity of transmitted radiation. The Low-E4 glass works like a sunblock to filter ultraviolet (UV) rays from damaging interior fabrics.
- Low-E4 glass features an invisible titanium dioxide coating, which makes cleaning easier. When sunlight hits the surface of the window, it loosens dirt from the glass, allowing rain to wash it away effortlessly without leaving water spots behind.
