Unilin the manufacturers of Durélis VapourBlock use up to 80% recycled wood for the production of its structural construction panels. All wood is sourced from FSC or PEFC certified forests. During production wood is crushed and thoroughly purified, after which high quality construction panels are manufactured. Wood which is too heavily contaminated is separated and burnt in a bio-power station to produce energy for powering production. The goal of all these initiatives is to achieve CO2 neutral production by 2015.
