What Is Knauf Loft Roll 44 100mm Insulation Roll? 

100mm Knauf Loft Roll 44 Insulation Combi-Cut (13.89m2/Roll) is an advanced thermal insulation roll designed specifically for pitched roofs at ceiling level.

100mm Knauf Insulation Loft Roll 44 comes in partially cut (Combi-Cut) rolls for use with timber joists at 400mm or 600mm centres, or uncut as a full-width roll, helping you maximise on-site efficiency. 

It also offers excellent thermal and fire performance with a thermal conductivity of 0.044 W/mK (numerically implied in its title) and an impressive A1 Euroclass fire rating.

Characterised by its odourless, rot-proof, and non-hygroscopic properties, Knauf Loft Roll 44 100mm insulation roll is designed to resist vermin and prevent the growth of fungi, mould, or bacteria, ensuring a healthier and safer environment.


Where Is Knauf Loft Roll 44 100mm Insulation Roll Used? 

Loft Roll 44's primary use is for the thermal insulation of pitched roofs at ceiling level, although it can also be used to thermally insulate floors. These 1140mm wide short-length rolls are supplied partially perforated to produce either 2 rolls 570mm wide or 3 rolls 380mm wide.

Primary Applications: 

  • Pitched roofs at ceiling level 
  • Floors


When used at ceiling level it is usually laid in two layers, with the first layer between the joists and the second layer over, and at right angles to the joists. A first layer gives sufficient thermal performance, but a second layer will improve the thermal resistance of the buildup even further. 

The rolls are easier to install correctly than other insulants such as rigid boards because they adapt to any slight imperfections in the substrate and knit together, eliminating any air gaps.

I've used this several times and it's a good roll. It's what I normally lay lofts with.

Peter Evans on

Turned up when it should've and the driver was very helpful

Kevin Jupp on

Arrived on time and my partner said it was simple to roll out and fit in the loft

Keeley Jarvis on

Very easy to install in my loft. Make sure you wear gloves, this stuff itches if you don't.

Dean Thistle on

Literally rolled it out across my existing insulation in my loft to give me an extra layer

Si Gayle on

I laid this in the loft between the battens, then I laid the 200mm over the top for extra warmth. Easy to install and cut, make sure you have protective clothing, you'll get itchy otehrwise.

Jim N on

Best price on the web delivery date was so soon I couldn't believe it until the 30 packs arrived on time Olga could guarantee availability so I'll be back to Materials Market
