Icopal Top 400 P

The declared product is used as an upper layer in a two-layer waterproofing system from BMI Icopal, made for roofs with particularly high demands on waterproofing. The system consists of an upper layer (Top) and a lower layer (Base), 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. The product is used also for strips in the roof edges.

Icopal Top 400 P is used fully torched as an upper layer in roofing, typically with an underlay of one or more layers of Icopal Base.

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