Key Features and Benefits
Euroclass A2 (s1, d0) Standards: Enhances fire safety and supports fire risk-averse designs throughout the building's lifespan.
W1 Class Water-Holdout: Ensures weatherproofing performance against water, wind, rain, and dust.
U-value Preservation: Optimizes thermal efficiency when installed in the building envelope
Superior Breathability (0.416 MNsg / SD 0.08m): Provides excellent water vapor permeability for better indoor air quality
All-in-One Weatherproofing Solution: Exceeds rigorous fire risk and weatherproofing requirements, offering reliable protection
Lightweight Product: Reduces logistical complexity, saving costs and lowering carbon footprint during transportation
Wider Roll Dimension (1500 mm): Increases productivity by covering more area quickly, reducing labor time and ancillary use
6 Months Free Exposure & UV Resistance: Offers flexibility in project scheduling, minimizing UV exposure risks
25-Year Warranty: Provides long-term assurance on performance properties, ensuring durability and peace of mind for users
DuPont™ Tyvek® Trifecta™
Tyvek® Trifecta™ doesn’t produce droplets or emit smoke when subjected to flame, making it a great choice for fire risk averse build-up designs of external walls cladding. It is engineered for fast and easy installation with non-combustible A2 tape.
Airtight and watertight yet vapour-open, the Tyvek® Trifecta™ non-combustible breather membrane also contributes to energy conservation and climate control, improving the comfort of occupants and contributing to higher internal air quality.
A Comprehensive A2-s1,d0 Fire Performance System
DuPont offers a complete A2 fire performance system, for non-combustible weatherproofing and condensation risk management, for all building types. Backed by 25-year DuPont Warranty: improved fire safety throughout the building’s lifespan.
