Proteus Waterproofing provided a bespoke roof specification to remove the existing roof coverings back to the structural deck and install a new Built-up Roof system comprising of new Rockwool
(non-combustible) insulation meeting the current building regulation requirement of 0.18 U-Value. The insulation was then waterproofed with the two-layer Proteus Pro-Felt® Ultima Plus system, BBA certified for a minimum 30 years.
