Reinforced high tear-resistance roofing underlay
Advantages
- Excellent occupational safety, even for large-sized roof tiles, in accordance with DIN 4426
- 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
Diffusion-open roofing underlay for installation hanging freely across all the rafters or else over roof sheathing, MDF and wood-fibre underlay panels, and over all thermal insulation materials, including blown-in insulation materials. Fulfils the requirements of DIN 4426, Clause 5.2 “Devices to protect against falls on roofs” (Table 2 – Tensile strength for sarking membranes as per DIN EN 13859-1, 5.2.6, such as ≥ 450 N/5 cm) for large distances between roof battens due to large-sized roof tiles.
