Putting compliance in the frame. With an increased focus on compliance with thermal, fire and acoustic performance for external walls, ROCKWOOL Timber Frame Slab has been engineered with an optimal density offering a low thermal conductivity, exceptional resistance to fire and outstanding sound absorption. The non-combustible stone wool insulation has dimensions specifically designed to enable quick and easy installation into timber frames. Manufactured using ROCKWOOL stone wool, Timber Frame Slab has the highest Euroclass A1 non-combustible reaction to fire. Acting as a barrier to fire, the slabs can withstand temperatures of up to 1,000°C. The use of stone wool insulation also makes Timber Frame Slab an effective thermal insulator, maintaining comfortable indoor environments by protecting against fluctuations in outdoor temperatures. ROCKWOOL Timber Frame Slab has been tested to BS EN 13162, achieving a thermal conductivity of 0.034 W/mK. The tailored dimensions and weight of the slabs makes handling and installation simpler and also minimises waste. The optimised product weight increases the amount the coverage per pack and compression packing technology improves both transport and storage efficiency. ROCKWOOL Timber Frame Slab has been developed with a unique physical structure meaning it keeps its shape over time, regardless of changes in temperature and humidity. The dimensional stability supports performance for the lifetime of a building without sagging or slumping. Accreditations: CE Marked Low thermal conductivity of 0.034 W/mK Non-combustible and non-toxic, rated Euroclass A1 Non-direction stone wool fibres offer outstanding sound absorption
