Our Wood-Built Homes: created with high-performance insulating material
IGC Bois invites you to discover a selection of 4 insulating materials. Choose the material best-adapted to your insulating requirements to create your wood-built home.
Cellulose lining Cellulose lining is obtained from unsold newspapers, grounded and mixed with various other elements, which make it highly-resistant.
An extremely absorbent material, very permeable to water, but highly flame and fire-resistant. In addition, it is a way of recycling printed press.
Recognized as a key recycling method, offering an extremely favourable eco-balance, this material uses low-level grey energy. It is recognized as the insulating material which combines the best ecological and economical value. Its Qualities: • Highly flame and fire-resistant
• Renewable material
• Excellent economy/ecology value
Roofing Felt This flexible insulating material is made from a mixture of sand and recycled glass, to which specific resins are added. It is presented in the shape of rolled-up mattresses, which are easy to use.
It is water-repellent and non-capillary, meaning it neither absorbs nor holds water.
Although it is a non-renewable source, it is widely available. Its Qualities: • Can be recycled and used as an insulator as is
• High-insulating qualities
• Resistant to fir and water
Cork Used in Mediterranean regions, cork-oak provides a first harvest of bark after 25 years of growth. A new usable bark is then only available ten years later. The bark is reduced to granules which are expanded through steaming and transformed into panels or used as is.
Cork has a relatively reduced usage as it is not geographically widespread and it grows very slowly.
Its production energy cost is quite low and essentially linked to transport.
It is waterproof and highly flame and fireproof. It can also be recycled and used as an insulator as is. Its Qualities: • Can be recycled and used as an insulator as is
• High-insulating qualities
• Resistant to fir and water
Wood Fibre Made from untreated sawmill leftovers and from thinning wood, wood fibre panels are conglomerated with their own resin. This wood’s natural insulation capacity is increased through a defibering process.
This material, which comes from resinous and hard wood, and also from recycled wood, is a totally renewable energy resource and is widely available.
Often used for roof cladding, wood fibre panels supplement other insulators and strengthen the roof’s insulating performances by eliminating thermal bridges. The eco-balance is highly positive. Its Qualities: • Waterproof
• Totally renewable
• Widely available
