Why choose MDM VENTIA membranes?

High vapour permeability
VENTIA membranes effectively remove moisture from within the roof, protecting thermal insulation and the roof framework against damp and deterioration.
Weather resistance
Products in this range resist UV radiation, changing temperatures and strong winds, contributing to the long service life of the entire roof structure.
Wide choice of models
The range includes VENTIA NEO, VENTIA NEO V, VENTIA GOLD, VENTIA UNIVERSAL, VENTIA ECO and others. Each membrane meets different project needs, from energy-efficient construction to standard detached houses.
Easy installation
The membranes are also available with adhesive strips (e.g. VENTIA V), making installation quicker and easier and increasing the watertightness of the roof slope.
Polish product, proven in practice
MDM is a brand with many years of experience, whose solutions are trusted by hundreds of thousands of clients and contractors across Europe.

Key:

Mass per unit area – weight of 1 m² of membrane (the higher it is, the stronger the membrane).
sd – diffusion resistance coefficient (the lower it is, the better the vapour removal).
Adhesive – “V” versions have factory-applied adhesive strips, making installation easier and increasing watertightness.
