IKO Protorch is a high performance torch-on cap sheet. It is a robust membrane, weighing 5kg/m², and is ideal for roofing professionals. IKO ProTorch membranes are polyester based and incorporate a specially blended SBS modified bitumen coating with fast flow properties. Torching speeds are further enhanced by a thermofusable film and selvedge edge.

IKO ProTorch can be used as the cap sheet on suitable pour and roll or torch-on underlays as part of a built-up system or as refurbishment overlay to existing asphalt or selected mineral surface felt.
