Non-Combustible Structural Safety for Multi-Story Building Envelopes
DELTA-FASSADE FIREPROTECT A2 is the professional standard for facades requiring elevated fire restrictions, such as high-rise complexes, corporate headquarters, schools, and healthcare facilities. Built on an ultra-robust glass fabric substrate, it permanently safeguards external thermal insulation against harsh weather elements while serving as a critical fire defense layer. [1, 2, 3]

Key Technical Advantages & Features:

Non-Combustible Fire Class (A2-s1, d0): Certified under EN 13501-1 to severely hinder the spread of structural flames, minimize smoke development, and produce completely zero burning droplets or debris.
Open-Joint Cladding Design: Optimized for permanently rear-ventilated cladding systems featuring open joints up to 20 mm wide and a maximum opening ratio of 20% of the total area.
Elite Vapor Permeability: Boasts an exceptionally low Sd-value of approx. 0.06 m, ensuring outstanding breathability so that structural construction moisture dries out fast, keeping insulation perfectly dry and energy-efficient.
Extended Outdoor Exposure: Offers high UV stability allowing the membrane to remain fully exposed to open weathering for up to 16 weeks during the structural build phase before cladding installation.

Ideal Applications:
Equally compatible with hölzerne (timber) or metallische (metal) stand frame systems across a wide matrix of open-joint or closed-joint stone, composite, and metal façade architectures.
