Cromar Protect 1F Felt is suitable for use in cold ventilated pitched roof spaces. Cromar Protect 1F is a strong, cleaner and cheaper alternative to traditional bitumen based 1F felts.
Unlike bitumen based 1F felts, Cromar Protect can act as a temporary cover to your property, prior to the slates or tiles being installed.
Cromar Protect 1F Felt is a non-permeable and non-breathable roofing felt. Manufactured in the UK, this 1F roofing felt is composed of lightweight yet durable three-layer polypropylene sandwich.
Installed quickly and easily, this roof underlay will protect your cold ventilated roof space from wind-blown water, snow and dust. Simply to install by draping horizontally over your joists. Slates or tiles are then installed in the normal manner.
