Thermobar Interbar to meet changing requirements for energy efficiency

Thermobar Interbar, manufactured by Thermoseal Group, is a bespoke range of bar designed to replace existing internal aluminium systems that simulate multi-pane windows.

It is a plastic alternative which helps to improve energy efficiency and minimise the potential for condensation on an insulated glass (IG) unit around the surface mounted system. According to BS EN14351, using internal aluminium systems can result in a u-value penalty on the sealed unit which can significantly affect the energy rating of the unit. We suggest that this will eventually affect the Window Energy Rating (WER) system which currently does not take into account internal Georgian or multi-pane systems. This new bar is designed specifically to complement Thermobar Warm Edge Spacer (although it can be used with other warm edge spacer systems) which is officially at the top of the list of the most thermally efficient spacer systems suitable for use with both PU/PS and hot melt sealants as per figures published on the new Bundesverband Flachglas (BF) Data Sheet – 0.14W/mK. Thermobar Interbar can be supplied with compatible centre and edge keys in 11.5mmx18mm and 15.5mmx18mm. It is currently in stock in black, but grey and white alternatives will be available in the New Year. Mark Hickox, Sales Director at Thermoseal Group, says: “Our innovation centre is working tirelessly to expand our range of cost-effective warm edge accessories. Thermobar Interbar has been in development for over 2 years and we have received some excellent feedback from our customers using it so far.By manufacturing the products ourselves we can provide energy efficient solutions at a competitive price.

“We are currently asking our customers to speak to our area sales managers so we can demonstrate how cost-effective our warm edge solutions are when replacing aluminium alternatives and helping to improve the energy efficiency of their units.”
