DuO High Tech

DuO High Tech is a unique waterproofing membrane that has up to twice the lifetime compared to other standard products on the market. It is used for new construction and for the renovation of existing flat roofs with leakage problems.

The top side of the membrane is made of a hard UV resistant plastomer TPO-bitumen layer. This makes it very durable and gives it a high melting point that copes with the high temperatures in a tropical climate.

An extra strong composite reinforcement of polyester and fiberglass in the middle makes the waterproofing membrane tear – and puncture resistant and shrink-free.

The underside of the membrane is made of elastomer SBS-modified bitumen for excellent adhesion. The seam of the membrane is also made of SBS- modified bitumen providing perfect an SBS to SBS overlap for an optimal watertight result.

The membrane has an extra protection in the form of mechanically pressed natural slates. The slates loss over time is minimal (less than 3%) and that makes the Duo membrane practically maintenance free.
