What Is Rockwool Insulation?
Rockwool is also known as mineral wool that is similar to fibreglass and comes with easy-to-install batts. As the name suggests, Rockwool is made of rocks but not in a way you imagine it in the first place.
The natural rock is heated in a furnace until it melts into a liquid. It is heated to 3000 degrees where the magma like liquid is then exposed to a high-pressure jet of steam or air. Finally, it is spun at high speed into long fibre stands. There it is. The strands are then compressed into thick, dense mats which are quite convenient-sized batts of insulation.
Properties of Rockwool Insulation
Rockwool insulation originates from volcanic rock. Compared to other chemical products like polyurethane foam, Rockwool is a vapour-permeable material.
This means that is the risk of damp is relatively low because the damp can freely circulate and evaporate. This is why Rockwool insulation is popular for cavity wall insulation as there are higher chances of cavity getting in touch with the damp.
Many insulation materials lose their insulation value in years to come. However, this is not the case with Rockwool insulation. The initial value of Rockwool material is retained for a much longer time, which makes it worthy of investment and the house will be insulated for decades to come.
- Rockwool is made from natural and sustainable material.
- It contains more than 70% of recycled content.
