Glass wool, for thermal and acoustic insulation, is composed of more than 95% of natural raw and recycled materials – 80% recycled glass and sand – and saves up to 90% of the energy used to heat and cool the building in which it is laid.
The amount of energy required to produce it is significantly less than the energy required in many other insulating materials (ratio of at least 1 to 4).
Thanks to continuous investment in people, technology and resources, Isover offers a complete range of solutions in glass wool which is characterized by its sustainable vocation thanks to the recent innovation introduced on the market, Isover 4+ glass wool.
Introduced in the domestic market in May 2014 and produced entirely in Italy, within the plant of Vidalengo Caravaggio (BG), Isover 4+ is the new glass wool colour ivory, made of recycled glass, sand and a special binder – Saint-Gobain’s international patent – made from natural and renewable raw materials, developed to provide greater well-being and sustainability in the interventions of acoustic insulation within a building.
Isover insulation has an average life of about 50 years, after which energy saving and non-CO2 emissions are 300 times higher than that used for its production, transport and installation.
Not everyone knows that the total raw materials used for the production of bitumen-polymer membranes, about 27% comes from recycled material, peculiarity of the industry that allows you to limit the consumption of virgin natural resources. This amount covers mainly polymers: almost all of those used in the production of bitumen-polymer membranes is composed of recycled material.
From the legislative point of view, the Directive 2008/98 / EC sets the goal of increasing the percentage of recycled material coming from construction and demolition scraps, as well as the Consolidated Environmental Matter focuses on scraps recovery to aid reduction of landfill.
New European and national regulations do not allow anymore to landfill processing scraps and membranes from demolition. Considering that approximately 80% of these products consists of a precious binder material (polymer-modified bitumen) derives not only the possibility, but also the advantage, of recycling.
