Isolation Products Are Classified Into The Following Groups
Mineral wool is an inorganic substance made from mineral fibers (siliceous sand and basaltic rock), with excellent thermal and acoustic insulation properties, combined with exceptional protection against fire. Rock wool, Glass wool
Recent news: Knauf Insulation presented, for the first time, at the Novabuild Fair its new insulation product: SUPAFIL Mineral Wool to inject
Polymeric products: They are those with the highest performance, but it is necessary to avoid those that have used HCFC hydrochlorofluorocarbons or chlorofluorocarbons CFCs, and that produce toxic residues.
Extruded polystyrene (XPS): It is high performance insulation and high resistance to weathering agents and aging. It is the only thermal insulator able to get wet without losing its properties.
Expanded polystyrene (EPS): It is high performance insulation and high resistance to weathering agents and aging.
PUR / PIR polyurethane: it is used in the form of rigid panels or application projected on site of light, rigid foam, with more than 90% of the cells closed and very insulating. It has a high adherence on any surface, it does not absorb environmental humidity and the price ratio insulating capacity is excellent. It has a high degree of combustion that makes it be replaced by other products such as mineral wool that is flame retardant.
Polymeric Insulation Products Can Cause The Following Negative Impacts On The Environment:
VOC emissions of volatile organic compounds or chlorofluorocarbons CFCs,
Filtrations to wastewater of high loads of organic compounds,
Production of large quantities of used solvents and non-recyclable waste,
High energy consumption in manufacturing.
Reflective light products: reflective multilayer sheets (LRMCs) sheets and thermo-reflective screens, composed of synthetic or natural fibrous materials, which reduce thermal transfer by conduction-convection (polyester, wool, linen, hemp …) and materials with air bubbles that reduce thermal transfer by conduction-convection.
Cellular glass: insulation made of recycled glass, which is sponged by thermal processes appearing a network of air bubbles inside. It is an insulator with excellent mechanical characteristics and low water absorption. It is a non-combustible material.
Natural products: they are ecological because they require light manufacturing procedures, but they need to be treated against insects and fungi, and the precaution must be taken that they do not become saturated with water because they lose their insulating properties.
