What options are there?
- Matting – Also known as quilt and blanket insulation. This is the most popular way of insulating a loft but it’s also used to insulate floors and stud walls.It is sold in rolls of varying depths and is usually made from glass fibre, rock fibre or sheep’s wool.
- Loose-fill – This is sold in bags and then poured out. Made from cellulose fibre, mineral wool, cork granules or vermiculite, it can be ideal for the corners and less accessible areas of your loft.
- Rigid insulation boards – This type of insulation is used for ceilings, walls and floors. It’s usually made from polystyrene, polyisocyanurate (PIR) or polyurethane (PUR). The pieces have to be cut to size before fitting.
- Blown insulation – Made from fire-resistant cellulose fibre (mineral wood or recycled newspapers) this can be used to insulate stud walls or lofts. It must be installed by a professional.
