Glasswool Pipe Section - InsulShop

Description

&#; For hot and steam pipe applications

huamei Product Page

&#; Fibrous material with HD foil facing

&#; Non-combustible material

&#; Easy to install pre-formed pipe sections

Glasswool pipe section is a non-combustible fibre-based insulation with a density of 64 kg/m3. The product is a good thermal insulator with a k-value of 0. W/mK. Glasswool is generally used for heating applications up to 340 degrees Celsius, such as steam pipe or hot water. It is not great for chilled applications, because the fibrous nature does not provide a vapour barrier. InsulShop faces the 1 metre long, pre slit pipe sections with a HD foil, to make it easier to work with on site.

Note of caution: When handling and processing Glasswool, the dust and fibres that get released are irritants to skin, eyes and the respiratory system. Make sure you wear the appropriate safety equipment.

Glass Wool: Applications and Thermal Conductivity

Aug. 26,

Glass wool is an insulating material made from glass fibers called borosilicate glass, which is arranged using an adhesive to form a wool-like texture. It consists of silica sand, recycled glass, and fixative, forming the perfect combination to provide excellent insulation and coating for houses.

 

Glass wool - thermal insulation (originally known also as fiberglass) is an insulating material made from fibers of glass arranged using a binder into a texture similar to wool. Glass wool and stone wool is produced from mineral fibers and are therefore often referred to as &#;mineral wools&#;. Mineral wool is a general name for fiber materials that are formed by spinning or drawing molten minerals. Glass wool is a furnace product of molten glass at a temperature of about °C. 


From the melted glass, fibers are spun. This process is based on spinning molten glass in high-speed spinning heads somewhat like the process used to produce cotton candy. During the spinning of the glass fibers, a binding agent is injected. Glass wool is then 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.

Applications of Glass Wool

Applications of glass wool include structural insulation, pipe insulation, filtration, and soundproofing. Glass wool is a versatile material that can be used for the insulation of walls, roofs and floors. It can be a loose-fill material, blown into attics, or, together with an active binder sprayed on the underside of structures. During the installation of the glass wool, it should be kept dry at all times, since an increase in the moisture content causes a significant increase in thermal conductivity.

 

Glass wool is particularly used as an interior thermal and acoustic insulation material. They are most often used under pitched roofs, on wooden floors, or on interior walls. Glass wool is mainly found in the interior of houses because it rapidly loses its insulating value when exposed to moisture.

Thermal Conductivity of Glass Wool

Thermal conductivity is defined as the amount of heat (in watts) transferred through a square area of material of a given thickness (in meters) due to a difference in temperature. The lower the thermal conductivity of the material the greater the material&#;s ability to resist heat transfer, and hence the greater the insulation&#;s effectiveness. Typical thermal conductivity values for glass wools are between 0.023 and 0.040W/m&#;K.

 

In general, thermal insulation is primarily based on the very low thermal conductivity of gases. Gases possess poor thermal conduction properties compared to liquids and solids, and thus make a good insulation material if they can be trapped (e.g. in a foam-like structure). Air and other gases are generally good insulators. But the main benefit is in the absence of convection. Therefore, many insulating materials (e.g. glass wool) function simply by having a large number of gas-filled pockets which prevent large-scale convection.

 

Alternation of gas pocket and solid material causes the heat must be transferred through many interfaces causing a rapid decrease in heat transfer coefficient.
