270mm Loft Insulation

The recommended depth of blanket style insulation (glass or mineral wool) for a loft is 250 to 270 mm. If you already have insulation, but it was put in some time ago, it is worth checking the depth, as only a few years ago the recommended depth of insulation was 200mm, and before that it was as low as 100mm.

At Gill Insulation, we are able to supply and install loft insulation to industrial and commercial buildings only; we do not work on residential properties.
