Choosing the Right Loft Insulation for Your Conversion

Loft Insulation

The importance of effective loft insulation

If you’re looking to make the most of the roof space in your home by carrying out a loft conversion, you will need to make sure you adhere to the latest edition of the statuary Building Regulations. This will mean insulating your roof in the proper way (choosing the right loft insulation material). There are many different types of insulation that can be used, some more expensive than others but all with great properties. The following is an overview of the types of insulation that can be used in your conversion.

Polyurethanes

There is a number of gas-based, plastic foam, polyurethane material insulation types. The best known and most popular are Kingspan and Celotax. They are fairly expensive but are much better at insulating than air-based mineral wool insulation types. This type of insulation is excellent where space is at a premium.

Blown-in

On some occasions it is possible to use wool, fibres and plastics that are not dry fixed but rather blown into position with a nozzle. The most popular type of insulation in this form is Warmcel which is constructed from a combination of recycled newspaper and cellulose fibre. Blown-in is a technique widely used in timber frame houses.

Multifoils

Made up of thin layers of aluminium foil and foam padding, Multifoil has excellent insulation properties and can be put to good use in houses with sloping roofs.

Extruded polystyrene

Extruded polystyrene is much denser than its expanded counterpart and is most widely used under loft flooring. There are several different suppliers of this type of insulation but Knauf is a recommended choice.

Natural minerals

The popularity of natural materials as insulation is becoming immensely popular. Wood fibres and hemp are both available in roll and slab variations and are excellent for insulating roof spaces and any timber walls that you have in your conversion. More popular than these though is sheep wool. This is a wonderful material with excellent insulating properties and is much better to use that fibre glass and mineral wool insulation; however, it is also more expensive.
