Spray polyurethane Blown cellulose

The high-performance solution for maximum airtightness and energy efficiency.

Spray polyurethane insulation involves applying a high-density expanding foam directly to the surfaces to be insulated. This material adheres perfectly to walls, floors, ceilings and foundations, creating a continuous barrier against air, moisture and heat loss.

Advantages :

  • One of the highest insulation coefficients (superior R-value)

  • Excellent airtightness: eliminates drafts and infiltrations

  • Also acts as a vapour and moisture barrier

  • Ideal for hard-to-reach or irregular areas

  • Resistant to mold, dust and allergens

  • Exceptional service life without sagging

Ideal for :

  • Basements

  • Exterior walls

  • Crawl space floors

  • Flat or pitched roofs

  • Garages, unheated spaces

An ecological, economical and effective option for thermal and acoustic insulation.

Made from fire-treated recycled paper, blown cellulose is mechanically projected into attics, ceilings or walls to create a dense mattress that slows heat transfer and dampens ambient noise.

Advantages :

  • Very good value for money

  • Ecological and recyclable material

  • Good thermal performance (stable R-value)

  • Noise reduction thanks to its soundproofing properties

  • Fire, insect and mildew resistant (treatment included)

  • Quick installation, no major work required

Ideal for :

  • Attics

  • Existing walls (with cavities)

  • Floors or suspended ceilings

  • Projects with optimized budgets or environmental objectives
