What is Loft Insulation?

Loft insulation consists of a layer of material lining your roof space that traps heat. It can either be laid between the horizontal beams along the floor of your roof space or in the rafters that support your roof. Loft insulation is an excellent way of limiting heat loss from your home.

How does Loft Insulation work?

Loft insulation materials work by blocking the passage of hot air through the material and preventing it from escaping.

Materials such as glass fibre limit the transfer of heat as it is a poor conductor of energy. The material’s fibres trap air providing a layer of insulation to your home.

As heat rises it is essential that your roof space is properly insulated to improve its energy efficiency. Around 30% of your home’s heating can be lost if your roof area is not insulated.

Buildings regs recommend loft insulation of 270mm as a minimum. For optimal efficiency it should also be fitted with as few gaps as possible. This helps to reduce heat loss and reduce energy bills.

Types of Loft Insulation

There are different types of loft insulation available to choose from. The most suitable type depends on your individual requirements.

Blanket insulation: The most common type of insulation for loft spaces is blanket insulation. Blanket insulation comes in rolls of fibre or foil and is laid between the flooring joists. For those on a budget, blanket insulation is the most cost-effective option. An added benefit is that it’s quick to install.

Sheet insulation: Also known as rigid insulation, consists of solid boards of either synthetic or natural materials. These boards provide high levels of insulation, are fire and moisture resistant. They are finished with plasterboard resulting in a clean and tidy look. Sheet insulation is more expensive than blanket insulation.

Spray Foam Insulation: Spray polyurethane foam (SPF) or spray foam insulation is a very effective insulation solution. As a material, it is flexible and versatile, bonding well to a variety of materials, including wood, steel, and plasterboard. SPF can be used to insulate walls, roofs, lofts and floors.
