PM MAXIM-TEC
Roofing underlay
Ideal for your application
- As a breathable, water and wind resistant roofing membrane for the best possible safety on pitched roofs with rear ventilated and non-ventilated designs.
- For renovation and new construction, including under photovoltaic systems and solar thermal power.
- As underlay and waterproof membrane for roofs and walls.
- Also very well suited as a sarking membrane and as temporary roofing material.
Applications
For pitched roofs with ventilated and non-ventilated constructions, for roofing (EN 13859-1) and walls (EN 13859-2), also suitable as a sarking membrane. Fulfils the ZVDH product data sheet for underlay membranes class UDB-A and waterproof membranes class USB-A. When used as temporary roofing, a nail sealing strip is required.
5 top-class finishing advantages
- Even, smooth polyester staple fibre technology:
Prevents formwork or rafters from becoming caught as on continuous filaments. - Full-surface grid embossing:
Ensures easier cutting – allows for fast and economical installation. - Homogeneous, tear-resistant PET base material with specialised TPU coating:
Makes the membrane puncture-resistant and able to handle loads evenly in all directions. - Integrated self-adhesive edge on the top and bottom – two adhesive strips on top of one another:
Bonds faster and firmer, with a better seal – strong even at low temperatures. - Extra-wide sealing lip:
Holds tight against wind and weather, while also protecting against moisture.
