Cellulose wadding is an ecological and recyclable material made from carefully sorted recycled newspapers or cuts of new paper from the printing industry. In addition to its ecological advantages, cellulose wadding provides excellent thermal and phonic insulation. Micro-organism resistant and rot-proof, it is open to water vapour diffusion. All these qualities mean that cellulose wadding is one of the best insulation materials in terms of ecological and technical value for money.
Compared with synthetic materials, cellulose wadding insulation requires very little energy for production and thus helps to protect the environment. Use of cellulose wadding therefore fully complies with low environmental impact sustainable development by reducing greenhouse gas emissions.
Jetfib’ouate bags come with measuring gauges which are used as markers during blowing (in attic spaces).
These gauges enable the fibres to be evenly distributed while ensuring the required thickness is applied (graduations in cm and R-values).
Room in roof
Insulation of the slopes between rafters
Cold attic spaces
Insulation unrolled on the floor (blowing)
Insulation between uprights (insufflation)
Between joists (manual application)
