R-VALUE: 40.0, SUITABLE FOR: new construction, retrofitTHERMAL PERFORMANCE: At R-3.5 per in., the cellulose in this system yields an overall value of R-40.PROS:• Familiar building process means lower labor costs with readily available materials.• If cellulose is used, the project has a lower environmental impact.• Large moisture-storage capacity allows wall cavities to dry gradually.CONS:• Fairly involved insulation process can add to labor costs.• Reduces interior space by 3%.
Swedish company Träullit produce Dekor Tiles from an environmentally-friendly recyclable material, made from ‘wood-wool’, cement & water. This combination of natural components is simple & clever. Wood fibres make the tiles sound-absorbent & give the product a heat-insulating, heat-retaining quality. This contributes to lower energy costs, reducing environmental impact. Cement provides strength, moisture resistance & fire protection. http://www.traullit.se/product/produkter/traullit-dekor/
Luffa Acoustic Wall Tiles by Luffa Lab aka Mauricio Affonso - luffa is a fast growing tropical vine plant from the same plant family as the cucumbers, pumpkins and courgettes. Luffa fibres form a complex network of cellulose that act like an open cell foam material that is both extremely strong and lightweight. Makes it a viable material for applications such as packaging, filters, low cost splints and acoustic insulator.
