Index Torch on System for Timber Substrates

Rollbase Polyester-V

Rollbase Polyester-V is an APP modified bituminous membrane that is nailed on to timber or metal substrate where torching is inappropriate. It is used as a base for torch adhesion of other sheets. The underside is coated with an exposed nonwoven polyester fabric, which is absorbent and traps the remaining humidity from wooden substrates or old waterproofing membranes. It is reinforced with a fiberglass to ensure the dimensional stability. The top surface finish: polyethylene film. Weight: 2.0 kg/m2. (Sika NZ Approved Contractor Only)

Mineral Proteaduo Triarmato

Mineral Proteaduo Triarmato is a multi-layer composite polymer-bitumen, torch-applied roof  waterproofing membrane. The upper layer is APP modified, which provides good heat resistance, the under layer is SBS modified, increasing the elongation and cold flexibility properties. It is reinforced with a dimensionally stable composite inlay of a fibreglass matt compressed between two layers of non-woven spunbond polyester fabric. The underside of the membrane has a thin polyethylene burn-off film for easy application. Top surface finish: mineral granules. Thickness: ~4.0 mm. (Sika NZ Approved Contractor Only)
