Alternatives to glass and mineral wool insulation

Installing glass wool loft rollMineral wool is one of the most popular materials used in domestic and industrial insulation applications. According to AMA Research, in 2016 it accounted for around 30% of the insulation product market’s overall value. Mineral wool and glass wool products are popular among building contractors and DIY enthusiasts for many reasons, including their lightweight, low-density build, ease of installation and fire protection performance.

Naturally, with increased popularity comes occasional reduced availability. So, what alternatives to mineral wool insulation are available? And which provides the best value for money and performance? Sheep’s wool insulation is one of the best choices.

Sheep’s wool insulation

With the increased focus in recent years on environmental issues and recycling of materials, natural insulation has come to the forefront of the market. One of the most popular examples is sheep’s wool, a material which has been used for centuries in textiles and other applications. Sheep’s wool does not cause itching, so it is easy and completely safe to install with no personal protective equipment.

SheepWool Insulation supplies a range of high performance, superior quality, natural insulation products based on pure new sheep’s wool. Their products are effective in helping to reduce heat loss and sound transfer in a wide variety of applications.

Aisling MacDonald from SheepWool Insulation explains that the main benefit of sheep’s wool is its breathability. “SheepWool Insulation is the only range on the market to use only 100% pure sheep’s wool. Pure wool is completely breathable, which ensures that you have ‘healthy’ insulation in your home,” she says. “Because of its ability to breathe, it will absorb moisture and therefore protect surrounding timbers, especially in older buildings.”

MacDonald adds, “Many other ‘natural insulation’ solutions will feature added elements such as polyester, which makes it less effective long-term. Our pure sheep’s wool is completely natural, breathable, and lasts a lifetime. It will also engage in air purification and provide high acoustic insulation performance. SheepWool Insulation is healthy for the building and healthy for those living in the building.”

There are several other common alternatives to mineral wool, glass wool and sheep’s wool insulation. A relatively recent addition to the natural insulation category is recycled polyester, which is available from SupaSoft and YBS. Other natural solutions include wood fibre and hemp insulation. For a more traditional approach, insulation board is available in PIR, expanded polystyrene (EPS), extruded polystyrene (XPS) and more. Multifoil insulation from SuperFOIL, TLX and others offers top thermal insulation performance.
