Refurbishment projects present unique challenges, particularly when it comes to fire safety and moisture management. Older buildings may have damaged or poorly installed cavity trays, or gaps around window and door openings that compromise thermal performance. Fire rated cavity closers and cavity trays are essential for addressing these issues, ensuring that refurbished properties meet modern standards for safety, energy efficiency, and durability.
A fire rated cavity closer seals openings to prevent cold bridging and restrict fire spread through the cavity. In older properties, unprotected cavities can act as hidden pathways for flames, making fire-rated solutions critical. These closers are typically rated for up to thirty minutes, providing valuable time in emergency situations and helping properties comply with UK Building Regulations.
Cavity trays manage moisture at key structural junctions, directing water safely to weep vents and preventing damp from reaching internal walls. In refurbishment projects, trays may need to be retrofitted to accommodate new roof levels, added insulation, or extensions. Correct installation restores the building’s moisture barrier, protects internal finishes, and reduces the risk of long-term damage, especially when combined with a non combustible dpc to provide a durable and fire-safe damp-proof course.
By using fire rated cavity closers and cavity trays together, refurbishment projects can achieve performance levels similar to new-build construction. This combination provides both fire safety and moisture management, helping older properties remain safe, dry, and energy-efficient for years to come. Contractors and developers must ensure proper installation to maximize long-term benefits.
