DASATOP

Advantages

• Best possible reliability thanks to ‘sub-and-top’ installation
• Protects building structures: humidity-variable s_d value allows for installation into the spaces between rafters and over the tops of the rafters
• Time-saving installation: no adhesion to rafters required
• No insulation cover necessary
• Easy to work with: particularly robust thanks to fleece reinforcement
• Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme

Areas of application

Suitable as a ‘sub-and-top’ vapour control (alternate terms: vapour check or retarder) membrane and airtight membrane for all structures with diffusion-open roofing underlay membranes (e.g. SOLITEX). If the roofing underlay membrane is installed onto sheathing, the maximum permitted s_d value of the underlay is 0.2 m (maximum g value: 1 MN·s/g ; minimum perm rating: 16.4 US perms). Also suitable in combination with wood-fibre underlay panels and MDF panels, and with fleece-laminated foam insulation materials (PUR, PIR, EPS etc.) with a thickness of 50 mm (2”) and greater.
