Bayonet’s Kiwi made Pauloid Bituminous Roof Underlay is your essential second line of defence against moisture and drafts.
Expertly designed for ease of use and quality, this is bitumen impregnated paper at its finest. Fully self-supporting down to 10 degrees, there’s no need for netting – just attach it directly to your timber or steel framing. Could it get any easier? Well actually yes, it could! This roof underlay also comes with printed laying lines so overlapping is a breeze. Can be used under any roof cladding and also provides temporary protection against the weather before you get your wall cladding or roofing material up.
