Klober air-open underlay for Grade 1 listed manor house

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