Mineral Wool Insulation vs Fibreglass

For many decades, fibreglass insulation (also known as glass wool insulation or glass mineral wool) was the standard for home construction. So what are the main drawbacks? First off, fibreglass is sourced from non-renewable materials, specifically plastic reinforced with glass fibres. Fibreglass Insulation is made from up to 30% of recycled glass, like Knauf DriTherm 37 (which is specifically designed for installation in external masonry cavity walls). Secondly, fibreglass insulation has been linked to adverse health impacts, including irritating the skin, eyes, and respiratory system.However, mineral wool and fiberglass exhibit a notable similarity in their composition and function. Specifically, glass and stone mineral wool insulates by capturing and retaining air within its intricate structure, thereby offering efficient thermal and acoustic insulation for various applications.Let's consider the properties and differences between glass and stone mineral wool:● Eco-friendly - Mineral wool is made of up to 80% recycled content, whereas fibreglass is only made from up to 30%.● Weight - Mineral wool insulation slabs are far heavier than fibreglass slabs. They do not bend or sag as easily as fibreglass insulation slabs.● Installation - Firm mineral wool slabs can friction-fit into place between studs and joists. Installing fibreglass can be more complicated because it requires staples and/or wires.● Fire resistance - Both fibreglass and mineral wool insulation are classed as A1 non-combustible on the Euroclass scale, which means that they do not burn.

How to Cut Mineral Wool Insulation Material

Mineral wool slabs are soft and easy to manipulate. Despite the slabs being dense and thick, you can handle them with ease. There are a few different ways to cut mineral wool that does not require expensive equipment. One of the most popular ways to cut mineral wool slabs is with a serrated blade or with a woodcutting handsaw.The first step is to mark the measurements on your slab. Marking measurements can reduce the possibility of mistakes. Once you have marked your measurements, you can begin cutting or sawing. It is important to cut insulation in a clear, open environment. You should also use safety equipment like goggles and aprons.
