The UK’s national system for rating Energy Efficient Windows – BFRC – has awarded Thermoseal’s Thermobar Warm Edge Spacer Tube an even lower energy value of 0.16W/mK¹ with or without its gas barrier tape. Thus, Thermobar has a universal value of 0.16W/mK for both plastic side and taped side.
The BFRC’s recently revised chart of approved spacer bar conductivity values has awarded Thermobar Warm Edge Spacer Tube with an even lower value of 0.16W/mK¹ with or without its gas barrier tape. This makes it the highest performing warm edge spacer tube recognized by the BFRC (the UK’s national system for rating Energy Efficient Windows).
This update is following further testing at IFT-Rosenheim. Thermoseal Group, manufacturer of Thermobar, has submitted additional samples of different cavity sizes of Thermobar to an independent test house. These tests have proven that Thermobar (with gas barrier tape) and Thermobar LITE (without gas barrier tape) have the same test results. Therefore, BFRC calculations have been altered to reflect this so that Thermobar no longer has a different value for its tape/backed plastic material. Thus, Thermobar has a universal value of 0.16W/mK for both plastic side and taped side.
Mark Hickox, Sales Director at Thermoseal Group comments: “We are proud to have manufactured our own British-made product which tops the charts against other warm edge spacer tubes imported into the UK market.
If you compare the taped bar value with the value of our nearest rival supplying a comparative structurally reinforced spacer tube, they are required to use a value of 0.29W/mK compared with our value of 0.16W/mK. This makes Thermobar the highest performance warm edge spacer tube… And it’s British!”
