Challenges
For funding purposes, the roof area was inspected and separated into two phases. Phase 1 of the roofing works presented a number of potential fire risks with combustible substrates and penetrations. The existing make-up performed poorly when tested against current building regulations.
Solutions
Following minor remedial works, the existing waterproofing system was inspected and deemed suitable for use as the air and vapour control layer. Thermal and acoustic upgrades were introduced through the installation of Hytherm MW mineral wool insulation, ensuring building regulation compliance and an acoustically sound teaching environment in compliance with BB93.
To complete the installation, Hyranger reinforced bitumen waterproofing system was installed, achieving a 20 year insured guaranteecovering waterproofing system materials supplied by Axter. In accordance with the NFRC’s Safe2Torch guidance, cold applied liquid waterproofing was required for detailing to fire risk areas; in this instance, Starcoat R was the system of choice due to uniform aesthetical finish and cost efficiency.
