Mineralised wood wool construction boards with an A2 fire rating
DRVOLIT D A2 is made of mineralised wood wool bonded together with cementitious binders and additives to form a compact unit. The mineralisation process greatly increases the fire resistance of wood wool. Its porous internal structure and surface design make it an excellent insulator in noise protection systems.
Characteristics
- Flame-retardant material, A2 – s1 d0 fire rating according to EN 13501-1
- Thermal conductivity: λ=0.074 W/mK
- Good adhesion to concrete and an ideal base for plastering
- Resistance to wear, chemical effects, parasites and mould
- Neutral in combination with building materials and metals
- Good sound absorption and high vapour permeability
- Great mechanical properties
- Easy formatting and other installation processing
- High phase shifting capacity for delaying the heat transfer through the fabric of the building
Purpose, use and installation
- Base for plastering in a ventilated facade system
