Produkty
Polyurethane (with TPU film) vapor-permeable roofing underlayment membranes (MWK) have become the standard on roofs, replacing other outdated technologies. In pursuit of our mission to find the perfect product, we have succeeded in creating membranes with even better performance by using new materials and innovative technologies.
Introducing MPFRoof – a modern roofing underlayment membrane that ensures excellent protection and comfort for your roof.
Our membrane combines two advanced layers: a robust needle-punched nonwoven fabric and an innovative thermoplastic polyurethane (TPU) film. This combination guarantees:
- Extreme Durability – Resistance to damage during installation.
- Flexibility – Easy and quick installation, adapting to any surface.
- High Vapor Permeability – Effective moisture management, even with minimal pressure differences.
MPFRoof performs excellently on both full and open decking as well as directly on roof trusses. It is resistant to high temperatures (up to +120°C) and provides excellent protection due to its high fire reaction 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 attached directly to elements of fire reaction classes A1 or A2, or at any distance from them. D-s1,d0 when attached directly to wooden or wood-based elements or at any distance from them.
** According to laboratory tests conducted under artificial aging, this period is determined based on the average annual UV exposure by the sun in Central Europe.
*** The recommended period for the membrane to remain uncovered on the roof should be as short as possible and depends, among other factors, on the construction of the membrane.
