BBA Agrément Certificate
Certificate type
A UV stable liquid applied waterproofing system suitable for many roof types.
Application
Satisfactory for use as a waterproofing layer in:
- Warm or cold exposed roofs on flat, completely flat and pitched roofs with limited access.
- Inverted roof specifications using aggregate ballast on flat roofs, including completely flat roofs with limited access.
- Protected inverted roof specifications using pavers or other suitable protection on flat roofs, including completely flat roofs with limited or pedestrian access.
- Green roof specifications on flat roofs, including completely flat roofs with limited or pedestrian access or pitched with limited access.
- Roof garden specifications on flat roofs, including completely flat roofs with limited or pedestrian access.
- Podium decks.
- Balconies with pedestrian access.
- Walkways.
Suitable substrates:
- Concrete.
- Plastic.
- Wood.
- Metal.
- Reinforced bitumen membranes (including mineral surfaced).
- PUR or PIR insulation boards.
- Mineral wool insulation batts.
Description
ParaFlex FD is a three component unsaturated polyester resin waterproofing system reinforced with a polyester fleece reinforcement that determines the breaking strength and elongation at break and provides for even layer thickness.
Features and benefits:
- With the correct primers, ParaFlex FD adheres to almost any substrate and the attachments are made permanently waterproof.
- Combination with most bitumen and plastic roof sealing sheeting is also excellent.
- BBA certified.
- Resistant to roots in conformity with DIN EN 13948 (FLL guidelines).
- Resistant to spreading fire and radiant heat, as specified in DIN 4102, Part 7.
- Fireproof as defined by BS 476, Part 3, 2004.
- Durability: Exposed applications should achieve an initial life expectancy of at least 35 years. When fully protected and subject to normal service conditions in an inverted roof specification with an open covering (e.g. aggregate pavers), the system can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated.
- Properties in relation to fire, buried applications: when used with one of the surface finishes detailed in Part iii of Table A5 of Appendix A of Approved Document B of the Building Regulations (England and Wales) or Technical Booklet E, Table 4.6, Part iv of the Building Regulations (Northern Ireland), would be deemed to be of designation AA.
- Resistance to wind uplift: The system will resist the effects of any likely wind suction acting on the roof.
- Resistance to foot traffic: The system can accept, without damage, the limited foot traffic and light concentrated loads associated with installation and maintenance operations. However, reasonable care should be taken to avoid puncture by sharp objects or concentrated loads. For areas of pedestrian access such as balconies and walkways, an anti-slip finish is applied.
- Curing time: With hardener and accelerator: Rainproof after 20 minutes. Walkable after 30 minutes.
