Frequently Asked Questions

What are the key characteristics of loft insulation?

Loft insulation works by trapping heat in air pockets and preventing it from escaping through the roof. It can be made from materials such as sheep’s wool, glass wool, or mineral wool.

The benefits of loft insulation include improved temperature control, reduced condensation issues, energy savings, and a longer lifespan for your home’s insulation. It is also eco-friendly and helps reduce external noise.

What are the different types of loft insulation available?

There are three main types of loft insulation: batt, blanket or quilt insulation, loose-fill insulation, and sheet insulation. Batt insulation is the cheapest and most common type, made of rock, glass, mineral fibre, or foil.

Loose-fill insulation is made of lightweight materials like cork granules, cellulose fibre, or mineral wool. Sheet insulation, also known as rigid insulation, is made of synthetic or natural materials.

How can I insulate my loft myself?

If you have an easily accessible and dry loft, you can insulate it yourself. Common options include using insulation rolls or blankets, which can be laid between and over the joists in the attic.

Insulation boards can also be used for both joists and rafters. However, it is important to ensure that the roof is in good condition and that the insulation meets current standards.

What are the advantages of insulating at rafter level?

Insulating at rafter level can provide a warmer roof space and reduce the risk of freezing tanks and pipes. Additionally, it allows for storage in the loft without raising the floor.

However, insulating at rafter level is more expensive than standard loft insulation, and it also requires insulating gable walls, party walls, and chimneys in the loft space to ensure effectiveness.

Are there any risks or drawbacks to consider with loft insulation?

Some companies offer to fix damaged or leaking roofs by spraying foam insulation directly onto the underside of the roof.

However, this method is not recommended as it can cause future problems and many mortgage companies are unwilling to offer loans for properties with foam insulation in the roof, making it difficult to sell such properties. It is important to ensure the roof is dry and in good condition before adding any insulation.

How can loft insulation increase the value of my home?

According to a UK government report, effective loft insulation can save up to £590 per year on heating bills and increase home value by 14%. It also improves the Energy Performance Certificate rating of your home.

Making energy-saving improvements in the home, including loft insulation, is a beneficial investment that not only saves money on utility bills but also adds value to the property.
