Polyurethane (with TPU film) vapor-permeable underlayment membranes (UWMs) have become the standard on roofs, replacing older technologies. Pursuing our mission to find the perfect product, we succeeded in developing membranes with even better parameters using new materials and innovative technologies.
Meet MPFRoof – a modern underlayment membrane that provides excellent protection and comfort for your roof.
Our membrane combines two advanced layers: a strong needle-punched fabric and an innovative thermoplastic polyurethane (TPU) film. This combination guarantees:
- Extreme durability – resistant to damage during installation.
- Flexibility – easy and quick installation, adapting to all surfaces.
- High vapor permeability – effectively removes moisture even with minimal pressure difference.
MPFRoof performs excellently on both solid and battened decking, as well as directly on the roof structure. It is resistant to high temperatures (+120°C) and provides superior protection thanks to its high fire resistance class (B-s1,d0).
With MPFRoof, your roof will be durable, functional, and always dry. Choose our membrane and enjoy reliable protection and long-lasting peace of mind!

*When fastened directly to elements with reaction classes A1 or A2 or at any distance from them / D-s1,d0 when fastened directly to wooden and wood-based elements or at any distance from them.
** According to laboratory tests conducted under artificial aging, this period is determined with respect to the average annual UV exposure from the sun in Central Europe.
*** The period during which the membrane remains on the roof without the main covering should be as short as possible, and shorter the more sunny days there are.
