Glass isol is a popular roofing material. This rolled sheet has a flexible backing made of fiberglass or fiberglass, which makes the work simple and convenient. The base on both sides is covered with a special binder based on bitumen, so the roof does not crack when bending, while maintaining water tightness. So that the layers do not stick together during storage, the lower part is protected by a polymer film, it easily melts when heated. A special lining or topping can be used as a top coat. Choosing the right glass isol is not difficult if you listen to the recommendations of our experts.

How to choose stekloizol

Purpose. Stekloizol is widely used in construction. For different designs, a canvas with certain properties is required.

  1. When it comes to waterproofing a foundation, ceiling, or installing an intermediate layer in a roofing pie, you can use the available types of glass isol with the designation HPP. The lining coating improves the heat and noise insulation properties of the structure, increases water resistance.
  2. Products of the CCI brand have a more solid basis. This material can also be used for waterproofing foundations and floors. In addition, it is perfect for inexpensive roofing of a garage or shed that is rarely walked on.
  3. Roll materials with the designation HKP and TKP are distinguished by maximum resistance to mechanical stress. Manufacturers manage to achieve wear resistance and durability by sprinkling the upper part with granite or slate chips. The purpose of such a canvas is the finishing (top) layer of the roof.

The foundation. In the marking, the first letter indicates the type of base.

  1. Fiberglass (X) allows you to get an inexpensive rolled product, which is used in cases where it is not subjected to a constant high load. Stekloizol on this basis is used for waterproofing the foundation and floors. In the roofing cake, it takes the place of the lining.
  2. Fiberglass (T) is highly durable. Stekloizol with this marking is able to withstand the frequent walking of people on the roof. Therefore, its scope is the formation of the upper layer of the roof.

Density. Stekloizol differs in thickness, and as a result, in density (kg / sq. M). The higher the density, the better the insulating properties of the material. But this increases the load on the building structure. The thickness varies between 2-5 mm. A thin material (2-3 mm) is suitable as a lining, and for a topcoat it is better to give preference to a canvas with a thickness of 3-4.5 mm.
