Q. Is Thermobar Warm Edge Spacer bendable?



Yes. However, as Thermobar is made with an engineering plastic, it needs heat to bend. This can be manually bent using a heat source, or bent using automated bending machines. With Thermobar, it is important that it works using traditional automated bending machines, as well as the new ones entering the market, so we work with a wide range of warm edge bending machine suppliers to optimise the speed that the product bends and maximise output.

Q. What is the Thermal Conductivity Value of Thermobar Warm Edge Spacer Tube?



Thermobar Warm Edge Spacer tube has a thermal conductivity value of 0.14W/mK on a 15.5mm airspace - with or without its gas barrier tape. This is the value as per IFT-Rosenheim physical testing (this includes desiccant and PIB). There is a Bundesverband Flachglas (BF) Data Sheet downloadable on the BF website certifying this figure. Please note that you'll also find a data sheet for Facades hosted on the BF site.

Thermobar is also Passive House approved and offers a phA rating for Arctic Climates (phA+ with Hot Melt secondary sealant).  

We are proud to have manufactured our own British-made product which offers one of the best thermal performances available worldwide.
