ADVERTISEMENT Even after 30 plus years on the market, Quanex’s Super Spacer® Premium warm edge spacer continues to stand up to the toughest demands for insulating glass (IG) production. The silicone based, all-foam formula offers manufacturers a premium energy-efficient and sustainable solution for high-volume production of dual- and triple-pane IG. As a true dual seal warm edge spacer line, Super Spacer Premium uses a high performing acrylic adhesive for its structural seal and is backed by a moisture vapor seal for maximum insulation properties. Adding a required hot-melt butyl or comparable low permeable sealant results in an unbelievably durable double seal that provides for amazingly consistent seal quality.
