Cellulose Insulation

We install cellulose fibre insulation, a high-performing carbon-negative product. Cellulose fibre is made from recycled newspaper. The paper is shredded and natural inorganic salts added for resistance to fire, mould, insects and vermin. The final product does a great job of keeping buildings warm, and can be blown into voids to achieve exceptional airtightness.

Our chosen insulation is Warmcel, a high-quality product well-established in the UK.

Is Cellulose Insulation Right for Me?

We can install cellulose insulation in most lofts, floors and timberframe walls. In many cases cellulose fibre can also be blown into voids which cannot be accessed using traditional insulations. To find out whether cellulose insulation is right for your project please feel free to get in touch.
