| Service | AiroTech can provide a quote for installing natural insulation using either Gutex woodfibre(Thermofibre) or cellulose blown insulation. |
| Overview | We use blown-in insulation to fill enclosed spaces (voids) between timber framed stud walls, ceilings, joists and rafters. This method of insulation fills awkward or inaccessible areas leaving no uninsulated air gaps. We can also install blown-in insulation (off-site) into prefab timber cassettes |
| Operatives | Our dedicated team of installers have been trained to take density measurements prior to carrying out the blown insulation installation. This ensures a consistent depth/breadth of insulation ‘to avoid slumping in for example walls’. |

Advantages of natural Gutex blown wood fibre
We only use blown-in insulation products which come with environmental product declaration (EPD) and declaration of performance (DOP) certificates i.e. Gutex wood fibre.

Frequently Asked Questions
Yes – if the existing insulation has settled or deteriorated, additional material can be added to bring it back up to optimal levels.
Yes – by improving thermal performance, it helps retain heat in winter and keep interiors cooler in summer. This can significantly reduce heating costs and associated carbon emissions.
Yes – when correctly installed, the materials and methods used conform to UK building regulations and meet current energy‑efficiency standards.
No – the process is fast and non‑invasive. A small hole is drilled into the area to be insulated, the material is blown through, and the hole is neatly sealed afterwards.
Many wood‑fibre products are treated for fire resistance and are compliant with safety standards. Always confirm the fire rating with the installer.
It helps maintain a moisture‑free indoor environment, delivers exceptional comfort, and contributes to the long‑term preservation of your property’s value.
Blown‑in wood‑fibre insulation is durable and can last 25 years or more, depending on installation quality and material density.
Blown-in insulation is a method of filling roof spaces, walls, or floors with loose insulation material using a specialised blowing machine. The material – often natural wood-fibre, cellulose, or mineral wool – is densely packed into the cavity, forming a seamless thermal layer. This technique is ideal for hard-to-reach areas and irregular spaces, offering excellent coverage, reduced heat loss, and improved energy efficiency. It is a fast, non-invasive solution suitable for both new builds and retrofit projects.
Airotech installs blown‑in wood‑fibre insulation, a natural material known for enhancing indoor air quality and providing excellent thermal comfort.
