Icopal Anderson SBS Torch-on Felt Silica Sand Underlay (16mtr Roll) is a glass reinforced, SBS modified bitumen membrane underlay that is used on high performance built-up systems on flat, pitched, or curved roofs. Torch applied; this underlay membrane is is impervious to water, insect attack, fungi, moss, lichen, and bacteria, and is unaffected by freeze / thaw cycling.

BBA approved and compatible with all materials normally used in roofing structures and finishes, Icopal Anderson SBS Torch-on Felt Silica Sand Underlay carries a 20-year manufacturer guarantee when installed in accordance with manufacturers guidelines.

Surface Preparation

All surfaces to receive Anderson SBS Torch-on Underlay must be smooth, clean, dry and free from all contaminates that may affect the adhesion and performance of the membrane. Surfaces must be free of sharp projections and mechanical fixings must be well driven to prevent damage to the membrane. Non-membrane surfaces, except insulation, must be primed with Xtra-Seal QD Bitumen Primer and left to dry completely prior to the application of the waterproofing.

Application

Anderson SBS Torch-on Underlay membranes are applied by torch-on application using a standard roofer’s torch. The membranes should be heated carefully ensuring the heat dispersible film on the underside is completely removed as work proceeds and checked for security ensuring a minimum 5mm bead of bitumen is extruded from all laps. Side laps must be a minimum 75mm with end laps a minimum of 100mm. The cap sheet side laps should be offset 300mm from the underlay to avoid a build-up of overlaps; end laps should also be offset.
