Steel Frame Slab
Manufactured using ROCKWOOL stone wool, Steel Frame Slab is Euroclass A1 non-combustible and able to withstand temperatures in excess of 1,000°C.
Stone wool makes Steel Frame Slab an effective thermal insulator, maintaining comfortable indoor environments by protecting against fluctuations in outdoor temperatures in both summer and winter. ROCKWOOL Steel Frame Slab has been tested to BS EN 13162:2012+A1:2015, achieving a thermal conductivity of 0.034 W/mK.
The tailored dimensions and lower weight of the slabs makes handling and installation quicker and easier, as well as minimising waste. The optimised product weight also increases the coverage per pack and compression packing technology improves both transport and storage efficiency.
ROCKWOOL Steel Frame Slab has been developed with non-directional stone wool fibres, meaning it absorbs noise and keeps its shape over time. The dimensional stability supports performance for the lifetime of a building by preventing sagging or slumping within the frame.
