Save money and the environment with Knauf Loft Insulation. With loft insulation installed, you’ll pay less for your energy bill and reduce your carbon footprint. For those planning a DIY installation, you’ll be pleased to know that Crown Loft Roll 44 is designed for simple installation.

Cost Effective

Insulating you loft will save you money on your energy bill. A quarter of heat loss in an uninsulated house is through the loft. By installing insulation, you’ll be saving money off your heating bill and helping the environment. With the price of electricity and gas beginning to skyrocket, loft insulation is rapidly becoming a must have choice for both the money savvy and the eco-conscious.

On average, a household that installs loft insulation saves £205 per year off their heating bill. That means a DIY installation costing £300 will pay for itself in less than 18 months. If you’ve already got some loft insulation and you’re installing a top up, you can expect to save around £60 per year. A DIY top-up costing £200 would pay for itself within four years.

Environmentally Friendly

A well-insulated home is an environmentally friendly home. Installing loft insulation to the recommended thickness will reduce your carbon footprint by about 1 tonne per year – 10% of the average Brit’s annual carbon emissions.

Crown Loft Roll is classified as having zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP). It is free from CFCs and HCFCs and any other material with ozone depletion potential in its manufacture and content and represents no known threat to the environment.

Easy to Install

Crown Loft Roll 44 Combi-cut is designed for easy installation. It comes perforated to save you time on installation.The perforations allow you to divide the loft roll into 2 rolls of 570mm width or 3 rolls of 380mm width.

Loft Roll 44 is made from lightweight and flexible mineral wool. Mineral wool insulation is designed for use at ceiling level in lofts with pitched roofs. It can also be used to insulate floors and partition walls – useful for both warmth and stopping noise travelling. Mineral wool insulation is non-combustible – so it provides some protection against the spread of fire. It will not rot, smell, or encourage the growth of fungi.

Basic installation instructions are included (and see our guide). For DIY installation, you’ll also need your own DIY manual.
