Keep the heat on the right side of the glass!

A breakthrough treatment available in Canada

SketchThermo, is a thermal insulation liquid coating for windows that blocks ultraviolet (UV) and infrared rays (IRs), while maintaining visible light transmission. This eco-energetic solution means that a window can receive a maximum of natural light while reducing indoor temperatures by 3°C to 5°C in the summer, for example. The result: a notable reduction in energy costs while offering greater comfort. Expect similar savings in the winter, since our thermal barrier prevents heat from escaping through windows.









SketchThermo advantages and benefits

Reduces heat penetration through windows in the summer and reduces the need for air conditioning

Reduces heat loss in the winter and diminishes heating needs

Minimal impact on visible light transmission (VLT)

Return on invested capital (ROIC) within 3 to 4 years (Depends on windowing ratio and insulation.

Reduces the impact of harmful UVs on materials inside a building

Reduces condensation 50% on the window’s glass surface, thus diminishing window dripping and the potential influx of mold contamination

High resistance to climate changes and with over 20 years of durability

Greatly reduces air temperature by up to 5°C in ideal conditions
