How to Insulate an Attic Conversion

How to insulate your attic:

1. Measure the distances between the rafters, joints and studs prior to purchasing your insulation. An insulation board, like Kooltherm K7 Pitched Roof Board, is a good choice for an attic conversion.
2. Use your measurements to mark out where you need to cut your insulation boards. Your boards should be lightly butted, with a tight fit between them. Measuring your space and cutting your insulation accurately is a key part of ensuring you’re insulating your space correctly. Any gaps in the rafters, joints or studs will allow warm air to escape, resulting in lost heat, higher energy bills and potential water vapour.
3. If you are cutting boards you should use either a fine-toothed saw or score with a sharp knife. If you’re scoring your boards, snap the board over a straight edge and then cut the facing on the other side.
4. To install your insulation, simply fit the cut boards into the spaces between your rafters, joints or studs, and continue until all the space is filled. You may find you have to cut a few pieces to ensure a perfect fit.
5. Once you have put your boards in place, you may notice some small gaps, you are going to want to fill these and can easily do so by using an expanding urethane sealant which insulates and stops draughts in small spaces, but it is not to be used on a large scale.
