In recent years, and in years to come, energy codes for buildings have and will continue to become stricter. This is driven by a desire to reduce the environmental impact of a building as well as to reduce the cost to maintain that building.
One area that many people look to when trying to improve a building is in its windows. Older buildings, constructed decades ago, or longer, were fitted with single pieces of monolithic glass, providing poor insulation. Eventually, IGUs, or insulating glass units, were created to improve insulation. IGUs were created using 2 pieces of glass and a spacer and therefore were much thicker than the original windows. Unfortunately, this meant choosing improved insulation at the sacrifice of the building’s original appearance. Additionally, switching to the IGUs also meant the costly process of ripping out the original window sashes.
To offer an alternative, VIG, or Vacuum Insulated Glazing was created to provide the best of both worlds. Pilkington Spacia™ is a VIG that provides the thermal insulation of an IGU with the thickness of a standard monolithic piece of glass. Pilkington Spacia™ is perfect for historical restorations and retrofitting projects.
