Klober’s air-open underlay has been installed on a Grade 1 listed manor house as part of a full roof refurbishment.
The underlay was specified by Philips Chartered Surveyors, who were responsible for a design specification to re-roof the entire property.
Klober’s Permo air was chosen for its water vapour resistance of 0.03MN/sg to ensure that the entire roof can breathe effectively.
Permo air is approved by the NHBC for use without supporting high level ventilation.
