150mm Loft Insulation from Knauf provides excellent thermal insulation when insulating the ceiling of your loft. Although this product is mainly intended for pitched roofs, its flexibility, lightness, and ease of use make it an ideal product to insulate suspended timber floors as well. 

Loft Roll insulation is a quilt insulation made of glass mineral wool, like all mineral wool products its density is quite low and while not totally soundproofing, only really low frequencies will leak through the insulation. It also boasts very good fire retardancy. 

Knauf 150mm comes in semi-perforated rolls 1140mm wide. This enables you to divide it into 2 rolls 570mm wide or 3 rolls 380mm wide. The installation process is simple enough, a first layer is placed between the joists, then a second layer should be added on top of it at a 90° angle to the joists. 

This insulation does not give out odors and will never rot. Nor does it favour the growth of fungi, mould or bacteria. It is also unsuitable for vermin.
