How it works
Windproofing with active moisture management
SOLITEX FRONTA QUATTRO wall lining membranes are equipped with state-of-the-art non-porous, monolithic polymer membranes that actively manage moisture. They offer significantly higher levels of structural protection compared with conventional, microporous membranes.
New standards: monolithic SOLITEX membrane
pro clima SOLITEX FRONTA QUATTRO has a non-porous, monolithic polymer membrane, which provides excellent protection against driving rain.
Compared to conventional wall lining membranes in which permeability is achieved via air exchange through the microporous membrane, a SOLITEX membrane enables active diffusion along the molecular chains. At the same time, SOLITEX FRONTA QUATTRO has a diffusion resistance with an sd-value of 0.05 m, an g-value of 0.25 MNs/g and a water vapor permeance of 65.5 US perms.
Its active moisture transportation makes the monolithic polymer membrane extremely quick drying, which optimally protects against ice forming on the membrane in winter. If ice should form, permeable wall lining membranes turn into vapour barriers (ice is impermeable) and then become moisture traps.
Additional features of the monolithic polymer membrane are the reliable protection against substances that impregnate wood (drops of water cannot penetrate the membrane even at reduced surface tension because there are no pores) and the particularly high thermal stability (melting point polymer about 200 °C (392 °F), PP about 140 °C (284 °F)). This thermal stability gives the plastic its extremely high ageing stability.
Top performance for all requirements
The functional film is reliably protected between two robust, particularly tear-resistant protective and covering fleeces made of polypropylene – ideal if there are high stresses when laying the membranes.
- The covering fleece is also water repellent and provides optimum protection against penetrating water. It protects the underlying specialist film from damage and UV radiation.
- As a result of the black colour of the outer covering fleece, the membranes are anti-glare.
- The membrane can be exposed to the elements for up to 6 months.
