When you search for a reliable bitumen felt supplier, you need to understand the differences between felt types. Bitumen felt—also called roofing felt, asphalt felt, or bituminous roofing sheet—serves a key role in waterproofing for residential, commercial, and industrial projects. In this article, we explain the common grades, highlight modern modifications such as SBS bitumen membrane and APP bitumen membrane, and outline the advantages of self-adhesive systems.
What Is Bitumen Felt?
Bitumen felt provides waterproofing by combining a saturated base mat—typically polyester or fiberglass—with oxidized or modified bitumen. Manufacturers supply it in rolls and offer various grades, including 2mm, 3mm, and 4mm. Contractors often install it as a base layer or a protective top layer on flat roofs, foundations, and underground structures.
Traditional Roofing Felt
Manufacturers produce traditional bitumen felt using oxidized bitumen and cover its surface with sand or fine minerals. Builders often choose it for smaller residential roofing projects or use it as an underlay beneath shingles. Although it provides basic waterproofing, it doesn’t match the elasticity or temperature resistance of modified bitumen types.
SBS and APP Modified Felt
Modern construction often requires improved durability, which is where SBS (rubber-modified) and APP (plastic-modified) bitumen felts come in.
SBS bitumen felt is flexible and cold-resistant, ideal for detailed surfaces.
APP bitumen felt offers superior heat resistance and UV durability.
As this article serves general guidance, you can find more technical specs on our dedicated pages for SBS membranes and APP membranes.
Self-Adhesive Bitumen Felt
For flame-free installation, self-adhesive bitumen felt is an excellent choice. It bonds to surfaces without torching, making it safer and faster to apply. This felt is often reinforced with SBS for improved flexibility and is ideal for smaller rooftops or repairs.
