Verified by manufacturer 11 days ago
BBA Agrément Certificate
Certificate type
Modified bitumen SBS polymer waterproofing membrane base layer.
Application
- Primarily used as a base layer.
- Can be used as an air and vapour control layer (AVCL) within a built-up warm roof.
- Intended for flat roofs, terraces, podiums, car parks and bridge decks, tunnels, foundations and underground structures.
- Suitable for application in low temperature conditions.
- Used in new build and refurbishment applications.
Description
Paraflex NT3 is a modified bitumen SBS polymer waterproofing membrane for use as a base layer or air and vapour control layer, under Paraflex waterproofing systems. The membrane compound is reinforced with a synthetic non-woven continuous filament polyester fabric, enabling plasticity, elastic behaviour and superior resistance to mechanical damage. The lower face is coated with Termotene® fusible film which aids unrolling and facilitates torch bonding to various substrates.
Features and benefits:
- Paraflex remains flexible at low temperatures and exhibits high resistance to thermal stress.
- Special formulation ensures high mechanical performance, cold flexibility at temperatures down to –25°C and excellent fatigue strength.
- Contain no asbestos, tar or other dangerous substances.
- Certification: BBA, NSAI, FM approved and CE marked.
