Installation Tips

Should be installed in line with the details set out in the BBA approved certificate and the terms laid down in BS5533

An unsupported underlay should provide a drape between rafters sufficient enough to ensure that water will run away from the batten fixing nail penetrations allowing draining from the eaves gutter

Contact between the membrane and the roof covering should be avoided during installation

Should be laid with a maximum drape of 15mm
