VentiLight (VentiLight Stripe Torch 10x1 m)

The declared product is used as an under layer in a two-layer waterproofing system from BMI, marketed under the brand Icopal, made for roofs with particularly high demands on the waterproofing layer.

The system consists of an upper layer (Top) and an under layer (Underlay), both based on SBS-modified bitumen. SBS increases the elasticity of the waterproofing layer and provides increased joint strength and service life. Two separate waterproofing layers provide a good protection against leakage. Products are either welded or glued with liquid bitumen into the substrate. In this EPD it has been assumed that the product is fully welded.

Two-layer waterproofing systems are defined in the product standard EN 13707 Flexible sheets for waterproofing.
