SOLITEX MENTO PLUS
Reinforced roofing underlay
Advantages
- Extremely robust thanks to reinforcement: suitable for blown-in insulation materials
- Flexible planning of construction schedules thanks to 4 months of outdoor exposure
- Well-protected building components: highly diffusion-open and maximum protection against driving rain and hail
- Dry building components: pore-free TEEE functional film actively transports moisture to the outside
- Permanent protection thanks to the high resistance to ageing and heat of the TEEE functional film
- Provides protection during the construction period: suitable as a temporary covering
Areas of application
For use as a diffusion-open roofing underlay over roof sheathing, MDF and wood-fibre underlay panels, and over all thermal insulation materials, including blown-in insulation materials.
