Fiber and wood wool

File ecological insulation: wool and wood fiber: insulation

Still confidential on the French market, insulation panels made of wool and wood fibers have more than satisfactory thermal and sound performance. Ecological and practical, these materials only made abroad are worth knowing. After conducting the survey among the few resellers present on our territory, HandymanDuDimanche invites you to discover these two insulators that we too often tend to confuse.

How it works?

Wood wool consists of wood fibers, lignin (naturally present in wood), but also synthetic binders, such as polyester, or natural, such as corn starch. Wood fibers, made from agglomerated chips without any chemical additives, are much more environmentally friendly than their counterparts. However, we add on these two insulators anti-organic minerals, to protect them from fire, and sometimes even natural latex to seal them. Thanks to the natural properties of wood, they protect us from both heat and cold. Not content with enclosing the air, the open structure of the pores of the wood also absorbs the sound waves.

Properties

The wood wool, flexible and light, is packaged in panels, in bulk or in rolls. It is mainly used to insulate floors or ceilings. More rigid and above all much heavier, the wood fibers are found only in panels. With inertia and a density 4 times greater than that of wool (270kg / m3), they offer us much more comfort. The panels are installed vertically in the under slopes, crawling, roofing or directly against the walls.

Advantages and disadvantages

Made from renewable materials, these wood-based insulation offer the advantage of being durable and fully recyclable. As efficient in summer as in winter, and relatively cheap, these panels are excellent value for money, between 10 and 30 euros per square meter. Easy to set up, they are within the reach of all good handymen. Regret that the wood fiber is reserved for solid frames because of its weight. Only manufactured abroad, these materials require transportation that requires a significant amount of energy and increases their ecological footprint.

Just as effective as cellulose wadding, hemp, sheep's wool, cotton or linen, fiber or wood wool panels are part of the wave of green building, even if they not all meet European standards.
