Fibreglass Base Sheet
BP fibreglass base sheet is a multipurpose waterproofing material made of a strong and stable fibreglass mat coated on both sides with a prime formulation of SeBS modified asphalt and surfaced (top and bottom) with fine mineral matter.
BP fibreglass base sheet can be used as the underlayment material on roofs having a slope greater than 2/12 in conjunction with BP RR701 Cap sheet to build a 2-ply roofing system.
BP base sheet may also be used in built- up-roofing systems as the first ply/vapor retarder.
BP base sheet can be mechanically fastened or adhered with hot or cold adhesive.
