Light-weight; easy to use, cut and handle the inserts have receptors which improve screw retention and help with accurate hardware positioning. Working alongside steel or aluminium reinforcements, they provide significant thermal benefits without affecting the strength of the window.
Commenting on the new development, Spectus brand manager Carmen Velilla said: “We were already doing our bit with multi-chambered frames but we were looking for a simple, cost-effective way to achieve even better thermal performance without compromising the structural integrity of our frames. Our new inserts do just that.
“The difference may be on the inside but this advancement is still a valuable selling tool for our customers. Once completed, the homeowner won’t know about the inserts but they’ll be sure to know about the benefits; a more efficient, better insulated home!”
