Window Insulation
Problem addressed
According to the US Department of Energy, about 30% of a home’s energy is lost through windows. However fully replacing windows can be expensive with high embodied carbon.
Overview of start-up
Window Insulation has a low emissivity coating which can be applied to existing windows providing proven energy savings and improved occupant well-being. The window insulation solution is a simple coating that can be applied onto existing glass and to any window type, shape or style.
The insulating coating reduces the transmission of heat into homes in the summer, reducing the temperatures during the warmer months while not affecting the amount of light passing through the windows. During the winter, the coating traps heat indoors by blocking certain wavelengths of the electromagnetic spectrum. This results in less energy needed to heat homes in the winter. The solution does reduce g-factor (from approximately 0.85 to 0.68 for a single glaze window) and therefore solar gains in winter, but it also significantly increases the retention of paid heat.
According to information supplied by Window Insulation, the benefits of this energy-saving alternative to costly window replacements include:
The window insulation results in increased occupant well-being, healthier working environments, reduced risk of skin and eye damage, and reduced damage to furnishings. The solution is proven to be maintenance free for 20 years and causes no significant change to window appearance.
What makes the start-up innovative?
Window Insulation provides a unique market solution with a coating that can be applied to existing windows to reduce their energy use. Their technology is similar to a low-e coating, but it performs better than some factory applied coatings. Window Insulation’s solution is also twice as durable, does not contribute to fire risk, and can be applied seamlessly.
How the start-up has been designed to scale-up quickly
They use a drop shipping distribution model and have access to large material volume. Additionally, Window Insulation has a partner training facility to allow widespread adoption of their solution.
