Acoustical Glass Wool insulation
Acoustical glass wool is an insulating material produced from glass fibers arranged into a texture like wool using a binder. The procedure traps millions of little pockets of air between the glass, hence creating an excellent thermal and acoustic insulation. Glass wool is formed into products with varied densities and thickness. Glass wool is made in slabs or in rolls with varied mechanical and thermal properties. Also, it may be made as a material that can be applied or sprayed in place, on the surface needing insulation. Glass wool is lightweight and offers considerable advantages during installation and transport. Additionally, glass wool is chemically inert having no impurities like sulfur, iron shots, and chloride. The product does not corrode metal and does not support growth of mold. It is made from inexhaustible raw materials and in every stage is environmental friendly.
Principles of Function of Glass wool
Gases have properties of poor thermal conduction in comparison to solids and liquids, thus making a good insulation material if their trapping can be done. For increasing the effectiveness of a gas (like air) it may be broken into small cells which cannot transfer heat effectively by natural convection. In convection, gas flows in a larger quantity, driven by temperature and buoyancy differences. In small cells it does not work well where the density difference is less to drive it.
With a specific end goal to achieve arrangement of little gas cells in man-made thermal insulation, polymer materials and glass can be utilized for trapping air in a foam-like structure. The same principle utilized in acoustical glass wool is utilized in other man-made insulators, for example, syro-foam, rock wool, wet suit neoprene foam fabrics, and fabrics, for example, polar fleece and Gore-Tex. The air-trapping property is likewise the insulation principle utilized in nature in down feathers, and insulating hair, for example, natural wool.
Health Problems by Glass Wool and Fiber Glass
Fiberglass will irritate the skin, eyes, and the respiratory system. Possible symptoms include irritation of skin, eyes, throat, nose, dyspnea (breathing difficulty), hoarseness, sore throat, and cough. It is demonstrated by scientific evidence that fiber glass is safe to install, manufacture, and use if work practices that are recommended are followed for reducing temporary mechanical irritation.
Uses of Glass Wool Insulation
Acoustical glass wool is a thermal insulation that comprises of entwined and adaptable glass fibers, causing it to “package” air, bringing about a low density that can be varied using binder and compression content (as given above, these air cells are the real insulator). Glass wool can be a material that can be loosely filled, blown into storage rooms, or, together with an active binder sprayed on the bottom of structures, panels, and sheets that can be utilized for insulating flat surfaces, for example, ceiling tiles, cavity wall insulation, roof tiles, ducting, and also curtain walls. It is likewise used to protect piping and for soundproofing. Acoustical glass wool absorbs sonic energy and is usually used to improve the acoustic performance of ceilings, walls, roofs, and floors.
