Energy efficiency is a growing priority in UK construction, and fire rated cavity closers and cavity trays play a significant role in improving wall performance. Fire rated closers eliminate cold bridging around windows and doors, while cavity trays prevent moisture from compromising insulation and structural components. Together, they help maintain consistent internal temperatures and reduce energy loss.
Closers are installed to seal the exposed cavity around openings, providing thermal insulation as well as fire resistance. Their ability to resist fire for up to 30 minutes also contributes to occupant safety, making them a multifunctional solution. In combination with cavity trays, they ensure the cavity remains dry, protecting insulation from water damage and maintaining its thermal properties.
Cavity trays are positioned at roof abutments, gable ends, and above openings to direct rainwater safely out of the wall. Proper moisture management prevents damp, mould, and potential degradation of the insulation layer, ensuring that energy efficiency targets are met over the long term. Pre-formed trays are straightforward to install, making them practical for both new-builds and refurbishment projects, particularly when used in combination with a fire rated cavity closer to protect openings and enhance both thermal performance and fire safety.
For modern housebuilders, using both fire rated cavity closers and cavity trays is essential for achieving EPC targets and delivering homes that are both safe and energy-efficient. Their combined use supports sustainable building practices, reduces heating costs, and ensures compliance with building regulations, contributing to overall project quality.
