High quality as a commitment

Our business started in Poland about 28 years ago. In the meantime, our expertise has been recognized in many other countries.

We put a high-quality offer and customer relationship at the heart of our business.  

We provide high-performance membranes for roofs and walls, hip & ridge tapes, and lathing mesh from glass fibre. We control all parts of production thanks to our 2 plants, located in Poland and Germany. We make regular investments to keep the manufacturing process updated & adaptable to new solutions. Our teams are experienced and are active members of our quality process.
