Sepa Light is a three-layer non-breathable roofing membrane for ventilated pitched roofs. It is a strong lightweight alternative to traditional 1F felt.
Suitable for use on ventilated pitched roofs.
All wind zones with taped headlap.
Wind zones 1-2 with batterned headlap.
Sepa Light should be laid in accordance with our installation.
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 and after installation
