To protect the Permo air at the eaves and to prevent ponding, Underlay Support Trays are available along with a range of adhesive tapes. Eaves closers are available for counterbattened roof structures. Wallint 50 and Wallint solar air barriers and vapour control layers.
Installation
Permo air should be laid in accordance with our installation details set out in the BBA approved certificate. An unsupported underlay should provide a drape between
rafters sufficient enough to ensure that any water will run away from the batten fixing nail penetrations at rafters, and allows it to drain to the eaves gutter.
Contact between the membrane and the roof covering should be avoided during and after installation. Permo® air should be laid with a maximum drape of 15mm.
