Loseley House is a Grade 1-listed Elizabethan manor house in Guildford. Philips Chartered Surveyors were responsible for a design specification to re-roof the property as partner Philip Acton explained. “The whole house was re-roofed, with Klober’s air-open underlay, Permo® air, chosen because of its high vapour permeability.
The house and gardens are of immense architectural interest and require products of the highest performance. With a water vapour resistance of 0.03 MN/sg,
Permo air will ensure that the entire roof can breathe effectively’. Permo air is approved by the NHBC for use without supporting high level ventilation.
