Why Choose Industrial Glass Wool Insulation?

Apr. 11, 2023

Glass wool (originally also known as glass fiber) is an insulating material made from glass fibers, which are arranged using an adhesive to form a wool-like texture. Glass wool and asbestos are made from mineral fibres and are therefore often referred to as 'mineral wool'. Mineral wool is a generic term for fibrous material made by spinning or drawing molten minerals. Glass wool is the product of a furnace at a temperature of around 1450°C of molten glass.


Composition of glass wool

Fibers are spun from molten glass. The process is based on spinning molten glass in a high-speed spinning head, somewhat like the production of marshmallows. During the spinning of the glass fibres, a binder is injected. The glass wool is then formed into rolls or sheets with different thermal and mechanical properties. It can also be produced as a material that can be sprayed or applied to the surface to be insulated.

The wool is pre-cut, while the blankets are supplied in continuous rolls. Compressing the material reduces its effectiveness. Cut it to accommodate electrical boxes and other obstructions, allowing a free path for air to pass through the wall cavity. Two layers of blanket can be installed on unfinished loft floors, perpendicular to each other, to improve the effectiveness of preventing thermal bridging. The wadding can cover the joists and uprights and the space between them.

The gaps between the lint (bypasses) can be places for air to seep in or condense (both of which reduce the effectiveness of the insulation) and require special attention during installation. For the same reason, careful weathering and installation of the vapor barrier is required to ensure that the lint performs optimally. Air infiltration can also be reduced by adding a layer of cellulose loose fill to the top of the material.


Glass wool insulation for industrial use and its applications

Glass wool is lightweight, thin, and environmentally friendly and is an excellent insulator. Glass wool is made from glass fibers, which also contain a certain amount of silica sand and recycled glass. It can be divided into loose wool and superfine wool. Loose wool is often used in the manufacture of glass wool and glass wool panels and also protects against thermal compression.

Why choose industrial glass wool insulation:

One of the best things about Glasswool insulation is that it is made from 80% waste material. It is arguably the most environmentally efficient element used as an insulator in any industry.


It is a thin layer of glass, light in weight, and easy to install anywhere.

It is waterproof and weather resistant. It will reduce defects in any building work. In addition, it has fireproofing properties.

These products are non-destructive and therefore no health-hazardous activities can occur. Other elements can lead to affect our body mainly the eyes.

It also has density properties that make it more robust.

Glass wool panels also have excellent sound insulation. It also helps to prevent sound transmission.


Uses of glass wool insulation:

  • For roof insulation: In order to install roof insulation, we need lightweight elements but powerful. It clarifies any industry where roof glass wool insulation is considered efficient and easy to apply to the roof.

  • For suspended ceilings: ceilings made of lightweight glass wool blankets benefit more than any other element.  

  • For pipe insulation: glass wool insulation can be used for pipes with thermal insulation material. It can be produced by applying thermal insulation in the pipes.

  • For cavity insulation: glass wool is considered a durable and flexible element for use as a filling cavity in buildings and houses. As mentioned in the article above, it is both waterproof and fire resistant, which is why it is used as a drywall filler and cavity filler in buildings.
