## Overview

Knauf Loft Insulation Roll offers a versatile, eco-friendly mineral wool solution designed to dramatically reduce heat loss through roofs and floors. Available in thicknesses from 100mm to 200mm, it delivers excellent thermal resistance (up to R4.5) and acoustic performance while being non-combustible and low-itch for easy installation. With potential heating bill savings up to £1000 annually, it’s the smart upgrade for energy-conscious homeowners aiming for comfort and sustainability.

## Description

Knauf loft insulation will save you a lot of money by reducing heat loss through your roof. 35% of your heat is lost through your roof. Loft insulation can reduce heating bills by £350 per year (rising to huge savings of £700 to 1000/ year from late 2022 due to rising energy costs). Even making your loft insulation thicker to the recommended 270mm can save £200-300 per year, or you can go even further and aim for passivhaus standards with around 450mm thick insulation. PassivHaus design means you can use very little or no heating.Installation100mm based layer insulation should be fitted between wooden ceiling joists with a second top layer of 150mm/ 170/ 200mm fitted ‘cross layered’ at 90 degrees to the base layer to give 250mm/ 270mm/ 300mm total thickness. You may need a wooden plank/ crawl board to help you with installation and protect plastered ceilings. NOTE: 270mm thick is recommended minimum in England and Wales, 350mm is minimum thickness in Scotland (150mm between joists and 200mm at 90 degrees above). increasing the thickness of insulation maximises energy efficiency. In new build and Passivhaus super-insulated properties, an insulation depth of 400-500mm is recommended. This is achieved by using 3 layers of insulation, for example 100mm between joints with 150mm and 200mm thick layers at 90 degrees above. Maximising insulation to all roof, wall and floor areas can mean your property will require very little heating energy and it will retain heat for longer into the next day after heating is turned off.Product FeaturesLightweight and economic insulation quiltProvides thermal, acoustic and fire performanceNon-combustibleVery Low Itch (nice to install and nothing like the old itchy fibreglass)ECOSE Technology - softer to handle compared with traditional mineral woolProduct Specifications Thickness options, 100mm base layer, 150mm top layer, 170mm top layer, 200mm super top up layerRoll Width 570mmRoll Length 100mm thick 12.18m, 150mm thick 8.05m, 170mm thick 7.03m, 200mm thick 6.84mRoll Coverage, 100mm covers 6.94m2, 150mm covers 4.59m2, 170mm covers 4.00m2, 200mm covers 3.42m2R-Value (thermal resistance) 100mm = 2.25m2K/W, 150mm = 3.40m2K/W, 170mm = 3.85m2K/W, 200mm = 4.5m2K/WThermal Conductivity 0.044 W/mKStandard EN 13162Material, Mineral WoolCan be used in conjunction with top-up layers and loft storage solutions such as LoftlegsEnvironmental

Review: Great insulation - I have used this product in the past from B&Q, so I knew it was good. It was very well packaged. I would recommend this product to anyone needing this type of insulation. Good thickness and very effective. Easy to install and cut with scissors. I would recommend thin gloves, long sleeves and trousers as it is mildly itchy.
Review: It's half a roll - Half roll , just what I needed ,no waste and 15 quid cheaper than a full roll , it's a shame its not half price but that's how I works,

*by A***R on 21 January 2026*

Half roll , just what I needed ,no waste and 15 quid cheaper than a full roll , it's a shame its not half price but that's how I works,

### ⭐⭐⭐⭐⭐ Quite expensive for what you get
*by B***Y on 31 December 2025*

Comes poly wrapped not opened yet but lot smaller than expected my fault for reading sizes more accurately. This may expand when it’s opened. Don’t think will buy again as quite expensive for size of roll but needed it for a small job.
