30 minute fire rating
11th December 2018
ISO CHEMIE Iso-Top Winframer thermal insulating and load bearing bracket system for the installation of windows has achieved E30 fire rating, confirming it can protect the window area from fire for a minimum of 30 minutes.
Winframer, which already has Passivhaus certified status, is a structurally solid, pre-fabricated installation frame, manufactured to accommodate cavities up to 250mm. This allows windows to be supported independently from the face of the wall regardless of any external cladding being in place.
Andy Swift, national sales manager for Iso-Chemie, said: “E30 fire rating, together with Passivhaus certification, enables Winframer to be specified for applications where both energy rating and safety are crucial factors – an ideal future design solution.
“Widely used in Europe, we are seeing growing interest among UK specifiers in Winframer to provide a solution to the current flawed method of installing windows to walls using metal brackets, creating a thermal bridge and probable route for fire to escape.”
