The Benefits Of Glass Scrim

There are many different applications where a scrim, a mesh of different types of fibers, can be used to add strength to a particular product while still providing flexibility to the desired degree.

Glass scrim is commonly used when there is a need to boost the strength of a particular product, such as concrete or even for asphalt or plastics. However, unlike a rigid material like rebar (reinforcing bar) which is commonly used on flat horizontal or vertical concrete forms, scrim allows for easy contouring and sloping without the need of complex shaping.

Manufacturing

The glass scrim is produced by specialized machines. The material, which is known as yarn, is a glass fiber that is fed into the machine in a continual process. This creates the horizontal and vertical components of the web or mesh. Unlike a true weave, the warp and weft fibers are not intertwined, but rather they are bonded together using a chemical process or heat, and sometimes both.

With this type of processing the mesh or the scrim produced is flat and even. Each small to large component of the scrim is identical to all the others, free from the strain or tension irregularities that can occur with a true woven product.

Advantages of Glass

With the choice of glass fibers as the scrim material, the result is a product that can be used in both alkaline conditions as well as in acidic conditions. It is also resistant to any type of rot and degradation through exposure to water, which is one of the reasons you will find this material in most construction types of applications.

It is not uncommon to find glass scrim used for cement work, including floors and walls. It is also used to provide strength yet flexibility around sinks and fixtures where there may be a need to create a contoured surface. This type of scrim is also commonly used when cement or other types of materials are used to make forms that are not standard in shape or size.

Scrim can be used in duct systems and products. It allows maximum flexibility yet also is very strong, and it can handle hot or cold temperatures, or changes between the two extremes, without shrinking or expanding. This not only prevents damage to the ducts but it extends the life, helping to save the cost of repairs and replacement over the life of the system.
