A free trial of Thermoflex Warm Edge Spacer is now being offered by Thermoseal Group, giving potential customers the opportunity to sample the high performance flexible spacer with a lowest thermal conductivity rating of 0.135W/m2K.

Sales director Mark Hickox said: “After much investment to ensure its superiority, we are delighted to be able to offer UK sealed unit manufacturers this opportunity.

“Thermoflex Warm Edge Spacer achieves the highest Passivhaus rating of phA+ for arctic climates and the best edge resistance within the Passivhaus component database of spacers – 6.30m K/W. Psi values are as low as 0.027W/m2K and are the result of continual investments in equipment and skills for testing and benchmarking Thermoflex in comparison to that of other leading flexible spacers.  

“The nearest competitor thermal conductivity value is 0.15W/m2K (as opposed to 0.135W/m2K for Thermoflex), which means that Thermoflex can be exchanged within current Window Energy Rating (WER) simulations, whereas competitor products cannot be exchanged within a WER incorporating Thermoflex warm edge spacer without a new simulation being required.”
