What is Argon Gas?
Argon is a colorless, odorless, and non-toxic gas that naturally occurs in the Earth’s atmosphere. Argon is chemically inert, meaning it does not react with other substances under normal conditions, making it ideal for various industrial and scientific applications. Our double glazed units are filled with Argon Gas for improved thermal performance and condensation prevention.
What is a Thermal Spacer
Thermal spacers contribute to the structural integrity and longevity of double glazed units by providing stable support and reducing stress on the glass panes and seals. This helps to prolong the lifespan of your windows and minimize maintenance requirements over time. Thermal spacers improve the energy efficiency, enhance the comfort and help prevent condensation. Our double glazed units include a thermal spacer.
What is Low-E Glass?
Low-E Glass, short for low emissivity glass, is a high-performance glazing solution engineered to minimize heat transfer and maximize energy efficiency. It is coated with a microscopically thin layer of metal or metallic oxide that reflects heat while allowing visible light to pass through. This advanced coating helps to keep heat inside during the winter and out during the summer, resulting in significant energy savings and improved comfort year-round. Talk to us about upgrading to Low-e glass.
