Applications
Loft Roll 44 200mm insulation roll is primarily used for the thermal insulation of pitched roofs at ceiling level, yet it can also be used to thermally insulate floors.
Primary Applications:
- Pitched roof at ceiling level
- Timber joists
- Floor systems
When installed at ceiling level, the insulation is typically laid in two layers. The first layer is placed between the joists, while the second layer is laid over the first, at right angles to the joists. While the first layer provides adequate thermal performance, the second layer enhances the thermal resistance of the overall setup.

Customer Reviews
I've used this several times and it's a good roll. It's what I normally lay lofts with.
Turned up when it should've and the driver was very helpful
Arrived on time and my partner said it was simple to roll out and fit in the loft
Very easy to install in my loft. Make sure you wear gloves, this stuff itches if you don't.
Literally rolled it out across my existing insulation in my loft to give me an extra layer
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.
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
Good insulation for loft, thank you.
Very good service and the insulation is very good
Kept us warm this winter
So easy to install!
