Thermoseal Group recently added a series of new sizes to its Thermobar warm-edge spacer series. New sizes include: 14.5 millimeters, 18.5 mm, 21.5 mm and 23.5 mm spacers with bespoke corner keys to suit. Recent additions also include Thermobar Interbar and fittings in 11.5 mm by 22 mm and 15.5 mm by 22 mm sizes, which also come in black, gray and white. Thermobar Interbar is the Group’s alternative to its Duplex fittings range, which is used to simulate multi-pane windows with standard Thermobar warm-edge spacer.
