MW U
Product description
MW U is a wall sandwich panel with a hard mineral wool core and concealed fixing system. Available in 80, 100 and 120 mm thicknesses, it achieves fire resistance EI 120 in the maximum configuration — a key parameter for fire separation partitions. Class A2-s1,d0 classifies the mineral wool core as a virtually non-ignitable material that neither sustains nor spreads fire. The concealed fixing system delivers an aesthetic facade with no visible fasteners. Acoustic insulation Rw = 32(-2;-3) dB and joint airtightness add further functional value. Core lambda 0.044 W/(m·K) is typical for hard mineral wool.
