Attic, roof slope and partition insulation.

A well-insulated home is more comfortable summer and winter, and brings energy bills down for the long term. As an RGE-certified business, we offer the full range of insulation techniques, from blown-in fibres to eco-friendly materials.

Attic insulation by blowing

For lost-space attics (unconverted), blowing remains the fastest and best-performing method. A machine projects loose insulation onto the attic floor, covering the entire surface — including hard-to-reach corners — with no thermal bridge. A half-day to a full day depending on the surface.

Rolled glass wool on roof slopes, linings and partitions

For converted attics, roof slopes, wall linings and partition interiors, we install panels or rolls between rafters or metal studs. Vapour barrier and air tightness applied according to best practice.

Which insulation should you choose?

There is no single best insulator — only one best suited to your project, budget and ecological sensitivity. Here are the solutions we install:

Material
λ (W/m·K)
Cost
Strengths
Glass wool
0.030 – 0.040
The best-known price/performance ratio. Widely used in attics and linings. Good fire resistance.
Rock wool
0.034 – 0.040
€€
Excellent fire resistance and good acoustic performance. Ideal for acoustic partitions.
Cellulose wadding
0.038 – 0.042
€€
Made from recycled newspaper. Ideal blowing in lost-space attics. Very good summer phase-shift.
Wood wool
0.036 – 0.042
€€€
Bio-sourced, vapour-permeable, excellent summer comfort. Well-suited to eco-renovation.
Hemp wool
0.039 – 0.045
€€€
100% plant-based, regulates humidity, no health risk. For demanding ecological projects.

λ: thermal conductivity. The lower the value, the better the insulator performs at equal thickness.

Financial aids & RGE certification

Our RGE certification (E-E195231) lets you access all energy renovation aids: MaPrimeRénov', Energy Savings Certificates (CEE), the zero-rate eco-loan, as well as local aid from the Departmental Council. We help you put the application together.

How an insulation worksite unfolds

  1. Audit & quote

    Site visit, surface measurements, recommendation of the most suitable system.

  2. RGE subsidies

    We cost the project with subsidies included and guide you on MaPrimeRénov' / CEE applications.

  3. Installation

    Blowing or panel installation by our team, following technical standards.

  4. Certificate

    Hand-over of the works report, RGE certificate and maintenance advice to preserve performance.

Attics, lining, eco-friendly: let's talk?

We prepare a detailed quote after an on-site visit, subsidies included.
