SBS Asphalt Roofing Paper , Black Torch Down Roofing Felt 4mm Thickness

4mm Thickness Torch Down Asphalt Roofing Felt Black PE Film Smooth Surface

Introduction:

Torch down asphalt roofing felt is a 4mm thick, SBS modified asphalt waterproofing membrane reinforced with a non-woven spunbond polyester carrier. The top surface and underside are both covered with a printed burn off polyethylene film.

Performance:

The unique formulation of high quality asphalt and SBS polymers and copolymers creates an extremely elastic sheet that provides excellent weathering properties. The hardness of the compound is changed during the year to make installation easier, regardless of the ambient temperature; the membrane is softer in winter and harder in summer. The polyester reinforcement enhances the mechanical characteristics, elongation and tear strength of the membrane, plus adds increased puncture resistance.

Application:

Application procedure may vary slightly depending upon site conditions. However, given below are general guidelines.

1.Priming:

Apply asphalt primer to a clean smooth and dry surface by brush, roller or spray.

2.Allignment:

Unroll and allign the membrane and re-roll correctly before torching. Overlap shold be at minimum 100mm.

3.Torching:

Use gas burner to heat substrate and underside of the membrane. Allows membrane a fast and safe laying. Roll forward and press firmly against the substrate to bound.

4.Sealing:

Heat both the overlaps and use round tipped trowel to seal the overlap. Excess compound should be smoothened pressed into seam using hot trowel.

5.Upstand:

All angles and abutmens should be sealed with extra care to ensure full boundage. Seal the edges well into into the grooves and protect with polysulphide sealant.
