Thermal Efficiency

A key feature of our double glazing is its innate ability to provide an incredible level of thermal efficiency for your Cardiff property. Expertly designed to trap the natural warm air found within your interior, our glazing effectively reduces the amount of heat transferring from your home to the outdoors, significantly reducing heat loss as a result. Our valued customers are able to enjoy U-values as low as 1.3 W/m2K.

Said natural heat is retained and reflected back into your home, ensuring that you and your loved ones can enjoy a warm and cosy temperature regardless of the weather outside. This is achieved through the small vacuum of space that sits between the panels of glass. As such, homeowners can enjoy a consistently comfortable interior temperature without the need or cost of their central heating. Save money on your heating bill as you enjoy comfortable warmth.
