Flat roof recovery boards

Recovery boards for flat roof refurbishments

Recovery boards for flat roof refurbishments sit below the waterproofing layer and above the insulation and can provide extra resilience for both components. Where heavy loads are placed on the roof, flat roof recovery boards can help spread that load and reduce compression on the insulation below. The recovery board can also provide the waterproofing layer with extra resistance both to the effects of foot traffic and accidental damage during routine maintenance.

Recovery boards for flat roof refurbishments with smooth surfaces promote a stronger bond with adhered waterproofing membranes. This can increase the roof’s wind uplift resistance and enhance the weather protection it provides to the building below.

Non-combustible recovery boards for flat roof refurbishments can offer an additional layer of fire resistance to the roof and act as a thermal break between an external fire and any combustible materials that may be present in the build-up of the refurbished roof.

Recovery boards for flat roof refurbishments that have high densities can help to reduce sound transmission through the roof, providing enhanced sound insulation for the building occupants.
