Why Cellulose Fibre?

Devana install only cellulose fibre insulation. Why? Because it offers an unmatched array of advantages over conventional products like fibreglass. 

Made from recycled newspaper, cellulose fibre is a superb insulation material. It's environmentally friendly and offers a good thermal barrier. In tandem with superior airtightness provided by the blown installation method, cellulose fibre outperforms many typical insulation products. All this means you can rely on Devana, and cellulose insulation, to keep you warm in winter.

The Installation Methods

We use a blown system to install cellulose fibre in timberframe walls, floors and roofs. This tightly packs insulation into every corner to provide great airtightness. Installation is fast and we can often pump insulation into voids which are otherwise inaccessible. 

Where insulation is being added to an existing structure, the blown installation method eliminates the need for major building work.
