Roofshield was recently used in the refurbishment of City College in Norwich. The benefits provided by the high performance Roofshield membrane were obvious to the roofing contractor, R.B. Watts.
Roofshield is an air and vapour permeable, highly water resistant roofing underlay, and has been made to the same specification for nearly 20 years, and has constantly met the evolving demands of the roofing industry to be the first choice of most roofing contractors.
The very low vapour resistance of 0.065MNs/g, combined with high air permeability, reduces the potential for interstitial condensation as far as possible, and does not require the use of a vapour control layer. This provides a robust and dependable solution that can be specified with confidence.
