Klober’s Permo therm board offers an insulation solution for pitched roofs.
The Permo therm board boasts the design of a Kooltherm insulation board, with an integrated underlay and tongue and groove edges. Self-adhesive edge strips have been added for sealing laps.
Preventing air leakage with Permo therm
Permo therm has been developed to prevent air leakage. Unlike square-edged boards, it can be fitted over the roof rafters to provide additional space within the roof area; suitable for all pitches, it has obtained LABC approval.
At 80nn thick, it can be laid on boarded or un-boarded roofs, from left to right and vice versa.
Whilst no ventilation of the batten/counter-batten cavity is required with most slates or tiles, Klober recommends the provision of ventilation for tight-fitting roof coverings.
