When it comes to materials for loft insulation your loft, the material you choose can make a significant difference to your home’s energy efficiency, helping you save on heating bills. From blanket insulation to rigid insulation boards, there are a number of options available. Choosing the right loft insulation material can also help to reduce noise and air leaks, as well as protect your precious belongings stored in your attic.

Blanket insulation, which is often made from recycled paper and mineral wool fibres, is an affordable option for insulating your loft. Its natural properties make it effective at retaining heat, and it’s available in thicknesses of up to 270mm. If you’re using blanket insulation, it’s important to ensure that all gaps, holes and voids are filled prior to installation to increase its effectiveness. You should also avoid obstructing any soffit vents or airflow pathways to prevent moisture accumulation.

Blown fibre insulation, or blown-in insulation, is another popular choice for lofts. It’s typically a mix of fibreglass, mineral wool or cellulose fibres that are blown into place by a professional installer. It is typically softer and more flexible than other types of insulation, making it suitable for hard-to-reach spaces. It’s important to note that cellulose insulation is irritant to the respiratory system and requires protective equipment during installation.

Rigid insulation boards, such as glass mineral wool, PIR or EPS foam are a more expensive loft insulation option. However, they can offer excellent thermal performance and are a good choice for those who want to insulate their loft without the need for accessing the roof space. They are also designed to be waterproof, which makes them a good choice for areas with frequent rainfall.
