The type of insulation that you choose depends on your circumstances. There are lots of advantages to choosing either rock mineral or glass wool insulation. Here are a few things to consider when making your choice. ●     Density - Mineral wool insulation is far denser than glass wool, which means that it performs better as soundproofing insulation.●     Installation - Rock mineral wool slabs are far more rigid than glass wool rolls. They are also resin bonded. Rolls are better for difficult, uneven areas that would not suit rigid slabs.●     Fire - Both rock mineral and glass wool acoustic insulation materials are rated A1 (non-combustible) on the Euroclass scale. The Euroclass scale regulates the classification of insulation materials across Europe.●     Moisture - Rock mineral wool is resistant to water. You do not have to worry about sag or rot when you choose rock mineral slabs as acoustic insulation for partition walls, cavity walls and floors. Glass wool insulation is not as resistant to moisture. When moisture takes hold of glass wool rolls, they become a breeding ground for bacteria, fungi, and mildew. People who live in areas with high rainfalls often choose rock mineral wool slabs.●     Price - If you are searching for cheap acoustic soundproof insulation products, you should browse through our glass wool rolls. Glass wool insulation is up to 10% cheaper than the rock mineral wool alternative. However, being less dense than rock mineral wool, it doesn’t achieve the same levels of acoustic performance.
