TekTherm™ AK-FR
A2 Fire-Rated Structural Thermal Break
Material Specification
TekTherm™ AK-FR Thermal Breaks are designed to be A2 Fire Rated as well as having a high compressive strength and low thermal conductivity. Compliant for use in buildings above 18m under Document B Building Regulations, this material allows specifiers to meet multiple requirements in one.
TekTherm™ AK-FR has been independently tested and meets A2,s1,d0 (Full laboratory report available on request). We can supply this as cut pads, strips or in any other shape within the parameters of the material.
