Product Description
Glass Wool Blanket
Glass wool board/glass wool blanket is processed by putting the thermosetting binder into the glass wool, by pressing and heating, and then, by curing. They are widely used for insulation, ventilation and the adjustment of air-conditioner in commercial industry and residential constructions.
Meanwhile, they have the effect of energy-saving insulating, sound-controlling and improving the indoor air quality. Glass wool building blanket is manufactured in custom sizes. It is used on the slabs of non utilized attics, betweenthe rafters of utilized attics, for horizontal applications where no load isapplied, for metal and sandwich roofs.
Building blankets are a popular option for insulating non-utilized attics. Among the many types of insulation materials available, glass wool blankets stand out for their exceptional properties. The lightweight nature of glass wool blankets makes them easy to transport and maneuver to the desired location on the roof. This makes it easy to cut and apply the blanket to the required areas.
One of the primary advantages of using a glass wool blanket is that it is highly resistant to tearing and other forms of damage during application. This helps ensure that each piece of blanket can be utilized effectively, with no waste pieces. Additionally, glass wool blankets can be easily adjusted to fit any type of roof, making them a versatile choice for a wide range of applications.
To optimize the performance of a glass wool blanket in an attic, it is important to ensure that the upper part of the insulation is properly ventilated. This helps reduce the risk of condensation in winter and facilitates the discharge of overheated air from the attic. It is also important to avoid covering the insulation with nylon or similar covers, as this can interfere with ventilation and reduce the effectiveness of the insulation.
For those looking to maximize the efficiency of their glass wool blanket, using an aluminum foil faced building blanket can be a wise choice. When rolled out with the foiled face on the heated side, these blankets can help reflect heat back into the attic, reducing heat loss and increasing overall energy efficiency. By considering these factors and selecting the right insulation materials, homeowners can ensure that their attics are well-insulated and energy-efficient.

Glass wool batt insulationGlass wool is an insulating material made from glass fiber arranged using a binder into a texture similar to wool. The process traps many small pockets of air between the glass, and these small air pockets result in high thermal insulation properties. Glass wool is produced in rolls or in slabs, with different thermal and mechanical properties. It may also be produced as a material that can be sprayed or applied in place, on the surface to be insulated. The modern method for producing glass wool was invented by Games Slayter while he was working at the Owens-Illinois Glass Co. (Toledo, Ohio). He first applied for a patent for a new process to make glass wool in .[1]

Gases possess poor thermal conduction properties compared to liquids and solids[2][3] and thus make good insulation material if they can be trapped in materials so that much of the heat that flows through the material is forced to flow through the gas.[4] In order to further augment the effectiveness of a gas (such as air) it may be disrupted into small cells which cannot effectively transfer heat by natural convection. Natural convection involves a larger bulk flow of gas driven by buoyancy and temperature differences, and it does not work well in small gas cells where there is little density difference to drive it, and the high surface area to volume ratios of the small cells retards bulk gas flow inside them by means of viscous drag.
In order to accomplish the formation of small gas cells in man-made thermal insulation, glass and polymer materials can be used to trap air in a foam-like structure. The same principle used in glass wool is used in other man-made insulators such as rock wool, Styrofoam, wet suit neoprene foam fabrics, and fabrics such as Gore-Tex and polar fleece. The air-trapping property is also the insulation principle used in nature in down feathers and insulating hair such as natural wool.

Natural sand and recycled glass are mixed and heated to 1,450 °C (2,640 °F), to produce glass. The fiberglass is usually produced by a method similar to making cotton candy. Molten glass is forced through a rapidly spinning metal cup, called a 'spinner'. The centrifugal force pulls the glass through small holes in the spinner. The newly created fibers cool on contact with the air.[5] Cohesion and mechanical strength are obtained by the presence of a binder that &#;cements&#; the fibers together. A drop of binder is placed at each fiber intersection. The fiber mat is then heated to around 200 °C (392 °F) to polymerize the resin and is calendered to give it strength and stability. Finally, the wool mat is cut and packed in rolls or panels, palletized, and stored for use.

Glass wool is a thermal insulation material consisting of intertwined and flexible glass fibers, which causes it to "package" air, resulting in a low density that can be varied through compression and binder content (as noted above, these air cells are the actual insulator). Glass wool can be a loose-fill material, blown into attics, or together with an active binder, sprayed on the underside of structures, sheets, and panels that can be used to insulate flat surfaces such as cavity wall insulation, ceiling tiles, curtain walls, and ducting. It is also used to insulate piping and for soundproofing.

Installing glass wool batts as ceiling insulationBatts are precut, whereas blankets are available in continuous rolls. Compressing the material reduces its effectiveness. Cutting it to accommodate electrical boxes and other obstructions allows air a free path to cross through the wall cavity. One can install batts in two layers across an unfinished attic floor, perpendicular to each other, for increased effectiveness at preventing heat bridging. Blankets can cover joists and studs as well as the space between them. Batts can be challenging and unpleasant to hang under floors between joists; straps, or staple cloth or wire mesh across joists, can hold it up.
Gaps between batts (bypasses) can become sites of air infiltration or condensation (both of which reduce the effectiveness of the insulation) and require strict attention during the installation. By the same token careful weatherization and installation of vapour barriers is required to ensure that the batts perform optimally. Air infiltration can be also reduced by adding a layer of cellulose loose-fill on top of the material.

Fiberglass will irritate the eyes, skin, and the respiratory system. Potential symptoms include irritation of eyes, skin, nose, and throat, dyspnea (breathing difficulty), sore throat, hoarseness and cough.[6] Fiberglass used for insulating appliances appears to produce human disease that is similar to asbestosis.[7] Scientific evidence demonstrates that fiberglass is safe to manufacture, install and use when recommended work practices are followed to reduce temporary mechanical irritation.[8] Unfortunately these work practices are not always followed, and fiberglass is often left exposed in basements that later become occupied. Fiberglass insulation should never be left exposed in an occupied area, according to the American Lung Association.
In June , the United States' National Toxicology Program (NTP) removed from its Report on Carcinogens all biosoluble glass wool used in home and building insulation and for non-insulation products.[9] Similarly, California's Office of Environmental Health Hazard Assessment ("OEHHA"), in November , published a modification to its Proposition 65 listing to include only "Glass wool fibers (inhalable and biopersistent)."[10] The United States' NTP and California's OEHHA action means that a cancer warning label for biosoluble fiber glass home and building insulation is no longer required under Federal or California law. All fiberglass wools commonly used for thermal and acoustical insulation were reclassified by the International Agency for Research on Cancer (IARC) in October as Not Classifiable as to carcinogenicity to humans (Group 3).[11]
Fiberglass itself is resistant to mold. If mold is found in or on fiberglass it is more likely that the binder is the source of the mold, since binders are often organic and more hygroscopic than the glass wool. In tests, glass wool was found to be highly resistant to the growth of mold. Only exceptional circumstances resulted in mold growth: very high relative humidity, 96% and above, or saturated glass wool, although saturated wool glass will only have moderate growth.[12][13]
