A wide range of products to enhance thermal performance

As window components go, it’s one of the smallest and easiest to overlook – but if you want to offer your customers long-lasting, energy-efficient and environmentally-friendly windows, spacer bars are critically important.

For over thirty years, Edgetech have been pioneers in warm-edge technology – spacers made from highly advanced plastics and foam rubbers, that offer vastly better thermal performance than the metal spacers that were once widespread.

It’s helped homeowners save millions of pounds on energy bills over the last three decades – and now, as countries across the world wake up to the huge threat posed by climate change, interest in warm-edge is surging.

Spacer bars – small but vital

Spacer bars separate the two panes of glass in a double-glazed IGU. For decades, they were made of aluminium – but as a metal, aluminium is a conductive material, meaning the resulting windows lost heat easily.

Super Spacer® offered a solution. First released in 1989, Super Spacer was made of flexible, heat-insulating foam that’s 950 times less conductive than aluminium.

That resulted in dramatically improved thermal efficiency – delivering smaller electricity bills and carbon footprints. But Super Spacer can also reduce external noise pollution by up to 2dB, condensation by up to 70%, and has been successfully tested in temperatures from -40 to 85°C.
