If access is easy and your loft joists are regular, you can use rolls of mineral wool insulation.

The first layer is laid between the joists — the horizontal beams that make up the floor of the loft — then another layer is laid at right angles to cover the joists and make the insulation up to the required depth.

If you plan to use the loft or attic for storage, you will want to lay boards over the joists. To get enough insulation, you can raise the level of the floor so you can fit enough mineral wool beneath the new floor level. You can do this by fitting timber battens across the joists, or you can buy purpose-built plastic legs that fit on the joists and support the new floor. Insulation stops heat escaping from living spaces, so it will make your loft space cooler, which could introduce or worsen existing damp or condensation problems.

If you are installing loft insulation yourself, please keep in mind that you may need to increase ventilation. Get professional advice before installing insulation to see if you can fix any damp problems first. An alternative way to insulate your loft is to fit the insulation between and over the rafters — these are the sloping timbers that make up the roof itself.

You can use rigid insulation boards, carefully cut to size, or you can have foam insulation sprayed between the rafters. Whichever approach you use, you will need a specialist professional to insulate your roof — this is not a DIY job. Some companies may offer to fix your damaged or leaking roof by spraying foam insulation directly onto the underside of the roof without first fixing the problem. We do not recommend that you do this. As with any type of insulation, you need to make sure that the roof is dry and in good condition before any insulation is added.

If you want to use your loft as a heated room, then you need to take a slightly different approach, and create a proper room in the roof. If you want to use your loft as a living space, or it is already being used as a living space, then you need to make sure that all the walls and ceilings between a heated room and an unheated space are insulated.

Make sure you insulate all the areas of wall and ceiling round any dormer window, and that you use high performance glazing for the window, or for any skylights. As with warm loft insulation, this is not a DIY job.

You will need a professional installer to ensure that the insulation is appropriate and complete, and that adequate ventilation is provided where needed. Air needs to flow in and out of your house so it stays fresh, dry and healthy.

A good installer will be sure not to block or seal any intentional ventilation. In Northern Ireland, building regulations require adequate ventilation when installing loft insulation. This usually means installing more vents if there are not enough.
