Donald Insall Associates specified Roofshield, the renowned pitched roof underlay, for the roof refurbishment. The roof structures of historic buildings can be complex in nature and demand careful consideration of moisture management, and condensation control. Many vapour and air permeable underlays use an airtight VP film layer to achieve their performance, whilst Roofshield’s patented SMS (Spunbond Meltblown Spunbond) structure allows high levels of airflow, in addition to the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible. It has an extremely high degree of vapour permeability, as well as air permeability, so will still perform in conditions in which air tight alternatives will not.

The high performance of Roofshield, backed by two BBA Certificates, has been successfully used in preserving and protecting the fabric of a wide range of historic and listed buildings for more than 21 years.

Nigel Smith, Director of Claude N. Smith comments on the use of Roofshield. “Roofshield was chosen by the architects as they required materials of the highest specification for the project. It has been excellent to work with, is exceptionally strong and durable and its superior air permeability ensures comprehensive protection for the historic college buildings.”

The one year project is due to be completed in October 2019, with additional projects confirmed for the re-roofing of Christ’s College and Clare College.
