• Energy Boost In Bristol

ISO Chemie’s thermal insulating and load-bearing bracket support system, Winframer, has been selected for a residential conversion project in Bristol.

Bristol architects Argyll Design Partnership specified the Winframer units for a private development involving the renovation of old stone cottages to boost energy efficiency.

The project utilises the ISO Chemie system to attach new windows, followed by the installation of insulation around the Winframer units and an exterior screed finish. This approach aims to significantly improve a building’s U-values and heat retention.

Passivhaus

Passivhaus certified and fire-rated for up to 30 minutes, Winframer is a prefabricated installation frame designed to support windows independently from the wall face, accommodating cavities up to 250mm.

This Bristol project aligns with a broader government strategy to reduce carbon levels in homes with single skin, cavity or non-cavity walls, which are notorious for energy, heat and sound loss.

Andy Swif, country director at ISO-Chemie says: “With new building regulations, property owners and window contractors need smarter solutions for refurb projects. By partnering with us, customers can achieve high-performance windows with efficient installations.”

Heavy loads

The composite Winframer brackets can support heavy window loads, including bi-fold doors, providing a reliable and high-performance support frame. Installation is straightforward, with windows attached directly using standard fixing screws or lugs.

A hinged insulation core and composite wood structural brackets integrate into the wall structure, ensuring compliance with window energy-saving regulations (EnEV) and the RAL quality assurance association.
