Edgetech’s Super Spacer flexible foam-based spacer systems acts as energy-efficient warm edge spacers
in insulating glass windows. They significantly reduce energy loss to the outside, largely prevent condensation
and also contribute to the lifetime of a window. On average, worldwide, more than 300 million metres are sold
annually in over 90 countries.
