The Underlayment / sarking membrane Top 150 is a 3-layer, highly vapour- permeable underlayment and is suitable for insulated, ventilated and unventilated pitched roofs, also with formwork, even if they are fully exposed to water, for example in the form of precipitation, and also in the case of closed joints as a façade membrane. It is characterised by an increased tear resistance, which makes them much easier to work with.
It is not necessary to maintain a ventilation slit between the membrane and the thermal insulation (mineral wool, fibre glass) for the installation – the product can be applied directly to the thermal insulation. The Underlayment / sarking membrane Top 150 is suitable for bonding with virtually all types of roofing – it is recommended for metal and aluminium roofs as well as for concrete and clay tiles.
