Traditionally windows used a highly conductive metal spacer bar to hold the two panes of glass apart, which sucked heat from inside to the outside. Super Spacer® is a non-metal, pre-desiccated, structural foam spacer system which provides excellent perimeter insulation for sealed glazing units and significantly simplifies insulating glass production.
80% of the energy lost through a window occurs at the edge of the glass because of the highly conductive nature of aluminium spacer. Super Spacer® is 950 times less conductive, blocking heat loss and reducing energy costs. Super Spacer reduces window U-values by up to 0.2W/m2K allowing windows to achieve the highest Window Energy Ratings.
