Loft-Roll-InstallationConverting your old, cold roof space into a fantastic new living area is a great way to add some extra space to your home. As we have already talked about, an under-used loft can give you a spacious new bedroom or a useful home office or gym.

One advantage to having your attic space converted into living space is that since the loft will become part of the heated part of the building, it will be necessary to insulate all the way round the envelope of the loft conversion. This will form part of the initial financial outlay of having your loft converted but should make your home far better insulated and therefore help maintain higher energy efficiency.

Heat Insulation

Loft conversions can be awkward to insulate properly, the sloping ceiling will need insulation cut and fitted between the rafters, and on top of them. As the plasterboard will have to be fixed to the rafters through the bottom layer of insulation, this insulation needs to be as thin as possible, so high performance insulation, such as foam board, will be required here. Similarly some of the walls and dormers will also need insulating with similar products before they are plaster boarded.

Insulating against sound

The new floor between the original living space and your new attic rooms will also needs soundproofing, and this is easily achieved by laying a mineral fibre quilt between the joists. Using heavier, denser sound insulation quilt, you are able to achieve a good level of noise suppression.

The same goes for any internal stud partitions between bedrooms or bathrooms. You should also consider insulating any party walls, both against heat loss and noise. A lining framework of timber stud will allow you to achieve both sound and heat insulation and this can be covered with sound-rated plasterboard.
