The 172 g/m² fiberglass mesh in a 1 x 50 meter format is the essential reinforcement material for ensuring durability and stability in a wide variety of construction, masonry, and thermal insulation projects. Specifically designed to prevent cracks and fissures, this mesh offers superior resistance to structural movement and temperature changes, guaranteeing professional and long-lasting finishes on facades, walls, and floors.

Thanks to its excellent flexibility and lightness, it is extremely easy to handle and install, adapting perfectly to different surfaces. It is the ideal complement to external thermal insulation composite systems (ETICS), as well as for mortar rendering, plastering, and repairing damaged walls. Its alkali-resistant treatment ensures that the material does not degrade upon contact with cement or lime, maintaining its reinforcing properties intact over the years.

Main Features

• Optimal weight: 172 g/m² which provides a perfect balance between tensile strength and handling.


• Practical dimensions: Roll 1 meter wide by 50 meters long, ideal for covering large areas efficiently.


• Anti-alkali treatment: High resistance to corrosion in alkaline environments such as cement and mortar.


• Crack prevention: Effectively absorbs and distributes mechanical and thermal stresses from the substrate.


• Versatility of use: Suitable for SATE systems, reinforcement of plasters, facade cladding and renovation of interior and exterior walls.

Frequently Asked Questions

What exactly is the 172 g/m² fiberglass mesh used for?

This mesh is used as a reinforcing element embedded in layers of mortar or cladding. Its main function is to prevent the formation of cracks and fissures caused by thermal expansion, building settlement, or impacts, significantly improving the cohesion of the cladding.

Is it compatible with any type of mortar?

Yes, thanks to its anti-alkali treatment, it is designed to perfectly withstand the alkalinity of cement, lime and gypsum mortars without suffering deterioration or losing its reinforcing capacity over time.

How should it be correctly placed on the construction site?

It is generally applied by placing a first layer of mortar or coating on the surface, pressing the mesh against this fresh product so that it is completely embedded (preferably in the outer third of the layer), and then smoothing it by applying a second layer. It is recommended to overlap the different rolls by at least 10 centimeters.

What advantages does it offer in SATE insulation systems?

In facades with thermal insulation, the mesh absorbs the stresses caused by solar radiation and sudden temperature changes, protecting the insulation and the final coating from breakage and detachment.
