IKO Perforated Vent Felt
IKO Perforated Vent Felt

IKO 20x1m Torch-On Venting Layer is composed of a perforated glass reinforcement which is saturated and then coated in polymer modified bitumen. A fine sand finish is applied to the top surface and a thermofusible film to the back surface. The thermofusible film over the perforations melts during application of the under layer and allows bitumen to flow through the perforations and spot bond to the deck.
