Due to the fact that hot air rises, another major area of domestic heat loss is that lost through the roof of your property. Figures show that 25% of the heat that you generate may be lost through the roof of your property and this can be dramatically reduced with the correct installation of loft insulation.

Ideally, loft insulation should be installed by experts to ensure that it is fitted safely and correctly. Where loft insulation is added, it is important that all wiring is dealt with safely and it is essential to ensure that all pipe work and tanks in the loft space are lagged (insulated) correctly, since there will no longer be the same amount of heat escaping into the loft space to protect pipes from freezing.

It is possible to fit loft insulation yourself, though it can be a messy and unpleasant job. Care should be taken to ensure that the insulation does not interfere with the ventilation of the loft space, since this could lead to condensation and this in turn could cause problems with the various timbers that make up the roof structure.

There are 3 types of British Standard loft insulating materials:

• Mineral Wool Quilt.

This is a roll of mineral wool which is unrolled and they laid flat in the loft. Ideally it should be laid in between the joists initially and then another course laid on top running across the joists. This will ensure the best possible levels of insulation.

• Blown Mineral Wool.

Using the same material as above but as loose fibres rather than in quilt form, this granular or ‘loose fill’ insulation is blown into place with specialist equipment and is ideal for use in areas where access is difficult or the use of mineral wool quilt is impractical.

• Blown Cellulose Fibre

Another type of granular or loose fill insulation that is blown into place with specialist equipment and is ideal for use in areas where access is difficult or the use of mineral wool quilt is impractical.

Blown materials may not be suitable for draughty loft spaces as the insulation may be disturbed by high winds.

It is important to ensure that the loft hatch is also insulated – it is obviously impractical to do this with blown materials and it is possible to buy polystyrene sheets of various thicknesses (the thicker the better the insulating properties) and these can be cut to size with a sharp knife and stuck to the top of the loft hatch with a suitable adhesive.

Loose fill insulation can also be installed as a DIY project.
