External wall insulation (EWI) is an incredible way for improving the energy efficiency of your home and helping save money on maintenance and those rising energy bills. Rockwool mineral wool (or “stone wool”) is a fantastic insulation material and is definitely something you should consider when it comes to improving the thermal insulation of your property.
There are two types of insulation used in a variety of applications and both perform slightly differently.
Whilst fibreglass is made up of thousands of glass fibres from a mixture of natural and recycled glass, rockwool is made of natural fibers of volcanic rock and other sustainable materials and agents that do not deteriorate over time.
Both achieve excellent levels of thermal insulation however rockwool has a number of added characteristics that make it an exceptional material for external wall insulation.
Rockwall insulation retains heat exceptionally well and prevents your home from losing or gaining heat through its walls and roof. Less energy is required to heat up or cool down the building – making subsequent energy bills lower in cost.
Rockwool mineral wool insulation is non-combustible and fire resistant to a melting temperature of over 1,000 degrees making it superior to other materials and vastly improving the fire safety and resilience of any home or commercial property.
Rockwall insulation has excellent sound-proofing qualities. Whilst it traps air and retains heat it also absorbs sound waves and prevents them from reverberating for a much warmer and quieter home. Rockwool can be used in walls, floors, and roofs for superior soundproofing qualities.
Whilst an incredibly sustainable option and environmentally friendly (containing up to 75% recycled materials) rockwool mineral wool insulation is also highly water-repellent and breathable. This allows moisture to escape through the fibre network thus reducing the possibility of mould and bacterial growth inside of your home.
Rockwall insulation has fantastic long-term performance and does not degrade or lose it’s effectiveness over time. In fact it’s proven to be one of the better materials for it’s efficiency over it’s lifespan on the property. Rock is one of the most hardened and robust natural materials you can find and rockwool insulation won’t move, shrink, or crumble.
Rockwool with it’s shorter fibre strands also provides rockwall insulation with incredible compressive strength. As rigid slabs they are easier to install than other insulation materials and can be fitted tightly together to minimise any possible gaps to maximise thermal performance. The lower density will help with slight imperfections in the substrate whilst the higher density top layer is the perfect surface for the application of the render.
Rockwool insulation has been designed and crafted to be the best insulation material for EWI.
