Cromar 1F Underslating Felt

Are you doing a restoration/new build project? Are you worried about potentially harming bats? Then our Cromar Bitumen 1F Felt could be your solution. This felt is darker and has a rougher surface which allows bats to have a better grip and maintain a safer environment within any structure.

This Cromar 1F Underslating Felt is primarily intended for use as an underslating felt on pitched roofing.

Storage and Handling:

Do not drag rolls across rough surfaces, you should lift them instead. Rolls must always be stood on their ends on a dry surface. If you’re using pallets do not stack more than two pallets high. Avoid mechanical damage and damp storage conditions.

Composition and Manufacture:

The base carrier consists of paper fibre formed into a material core of 150gm/m².  The carrier material is saturated then coated both sides in continuous operation using liquid penetration and oxidised bitumens. Prior to its final coating a hessian backing is introduced which adheres to the back of the sheets. This therefore provides extra strength. The coated material is finished with fine sand on both sides.
