The Winframer thermal insulating and load bearing bracket support system from Iso-Chemie has been specified as part of energy efficiency improvements to a number of residential properties in Coventry.

Passivhaus certified and fire rated to up to 30 minutes, Winframer is a prefabricated installation frame, manufactured to accommodate cavities up to 250mm that allows windows to be supported independently from the face of the wall regardless of any external cladding being in place.

The product’s application in Coventry is seen as part of a solution to meet a wider Government strategy to reduce carbon levels in homes that have single skin or non-cavity walls.

Andy Swift, sales and operations manager – UK and ROI, said: “Using Winframer as a platform for the windows to be moved forward, allows a cavity wall to be created outside the existing one. This can then be filled with insulation to massively improve thermal efficiency.”

The composite Winframer brackets can bear heavy windows loads, including bi-fold doors, to provide a reliable, strong and high-performance support frame. Installation is quick with windows attached directly and secured mechanically using either standard fixing screws or fixing lugs in the usual manner.
