Liquid and sheet foams emit a range of hazardous gases and vapors, leading to allergies, asthma, cancer. Therefore, this type of insulation may not be used indoors, and I would not recommend even outside since any masonry – brick, cement, concrete, not to mention the tree is permeable to gas molecules, in addition, we rarely organize a separate ventilation system in the house more often – ventilated. Styrofoam less dangerous than the foams, but also not recommended for internal insulation. Product of cotton insulation is a suspension of microscopic glass shards – or mineral fiber that can penetrate mucous membranes and lungs. Another danger – the fibers are fastened together formaldehyde resins, which is the source of allergies. Because after the weatherization work on the need to seal the layer of insulation and completely clean the air in the room. Eco-friendly foam insulation does not have harmful fumes and limitations of the above materials.
In addition, a significant difference is their water vapor permeability (this can not provide even cotton insulation – because we have to use vapor barrier). Another problem with heaters – aging. Leafy heaters lose their performance characteristics for 3-7 years. Quilted insulation have a nasty trend and pressed zamokat (through aging gidrobarer included). In 5-7 years there is an urgent need to replace them. Foam insulation – the longest period of operation, some foam heaters have a lifetime manufacturer’s warranty. What insulation would you recommend for insulation in the private use of a private home is unacceptable neekologichnyh uteliteley, because it is a grievous resource – the health of residents, especially children. Because – for insulation of private homes – eco-friendly foam insulation or, in extreme cases, cotton, and wool must be chosen from water-based adhesive, with mandatory sealing and fine-cleaning the air.
