| ROTHOBLAAS Flexi Band 100 100MMX25M 10 Rolls/Box |


Reinforced hydrosafe® high-performance vapour check, suitable for all fibrous insulation materials.
Air barrier, smart vapour control, and dense-pack reinforcement all in one. INTELLO Plus is the keystone to long-lasting airtightness and intelligent vapour control in walls and roofs.
- Best possible protection against moisture damage to structures and mould because this product is humidity-variable with a variation of a factor of over 100
- Can be combined with all fibrous insulation materials (including blown-in insulation)
- Permanent protection: officially tested and certified performance (ETA-18/1146)
- Protected winter building sites thanks to hydrosafe® behaviour
- Test winner in April 2012 with the German product-testing foundation ‘Stiftung Warentest’
- Easy to work with: dimensionally stable, no splitting or tear propagation
- Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme
- Vapour Variable: Low Class II vapour retarder in winter (<0.13 Perm), protects against condensation and maximum vapour openness in summer (13.2 Perm) to facilitate rapid drying to the interior. Protects the assembly during construction high humidity periods (70% RH) with a DIN 68800-2 compliant, hydrosafe value of 1.6 perms
- Works with a wide range of insulation materials, including Gutex wood fiber and cellulose dense-pack, Havelock wool, stone wool and fiberglass. The semi-translucent material allows dense packed, blown-in insulation to be inspected after installation
- Living Building Challenge Compliant — Red List Free
- Complies with NBC part 9.36.2.9
- Complies with NBC, BC, ON code as per CAN/CGSB 51.33-M89 independent lab testing
- PHI Certified Class A Passive House Component
- Pro Clima Intelligent Airtight system (TESCON VANA tape, ROFLEX gaskets etc) allows for fast, reliable installation
- Certified to ICC-AC528-Humidity dependent Vapor Retarders - ICC ESR 4854
Areas of application
Vapour check (alternate terms: vapour control or retarder) membrane for use on roofs, walls, ceilings and floors on structures that are open or closed to diffusion on the exterior, e.g. flat/steep roofs and green roofs, after appropriate design calculations have been carried out.
