Cavity formers ensure window openings are ready for installation.
Benefits of Cavity Formers.
Built-in thermal efficiency
Cavity formers incorporate an insulated core, which not only improves thermal efficiency for Part L Building Regulations compliance, but also saves time on site because no additional insulation needs to be fitted.
Cavity formers are very easy to install and eliminate the time-consuming process of fitting.
Prevent cold-bridging, condensation and mould
Using rigid cavity formers achieves a close fit around all building apertures to prevent draughts. It creates an effective damp-proof barrier and prevents cold-bridging, condensation and mould growth.
Eco-friendly made from 100% recycled material
Cavity formers are manufactured entirely from recycled post-consumer waste. Today, with the Code for Sustainable Homes offering credits to builders who use sustainable materials and energy-efficient products, Cavalok cavity closures are the obvious choice for every new-build project.
