Soffit Insulation
URSAPAN BLACK, URSA WALLTEC BLACK and URSA WALLTEC REFLEX slabs are for use as a soffit insulation under concrete, timber or metal flooring systems.
URSA WALLTEC BLACK - thermal conductivity 0.032 W/mK.
URSAPAN BLACK - thermal conductivity 0.035 W/mK.
URSA WALLTEC REFLEX - thermal conductivity 0.032 W/mK.
Design
URSAPAN BLACK, URSA WALLTEC BLACK and URSA WALLTEC REFLEX may be used to achieve the required U-value in the floor and also to enhance its acoustic performance.
URSA WALLTEC BLACK and URSA WALLTEC REFLEX both have a class leading thermal conductivity of 0.032 W/mK.
All three products deemed are non-combustible with a fire classification of Euroclass A1 (the highest possible rating) when tested to EN 13501-1 Reaction to Fire
Larger slab size means 12.5% fewer boards to install and 12.5% fewer fixings required.
A typical 150mm concrete slab will give approximately 50 dB Rw; this can be improved to over 65 dB Rw with URSAPAN BLACK, URSA WALLTEC BLACK or URSA WALLTEC REFLEX slabs and 2 layers of plasterboard as the suspended ceiling finish.
