Fixing net - for wall-ceiling heating - 1000x1mm - 50m2 IVAR.FIXSIT-ST

Product detailed description

This reinforcement mesh is commonly used in residential and commercial buildings where wall or ceiling radiant heating systems are installed. It ensures structural stability for the finishing plaster layer over embedded heating elements. Installers working with thin-layer plaster systems use this mesh to prevent cracking and improve adhesion between the plaster and the substrate. The product is suited for both new construction and renovation projects involving hydronic radiant heating.

During installation, the mesh is embedded into the plaster layer after the heating pipes have been laid and fixed. It supports even distribution of the plaster and helps maintain long-term dimensional stability of the surface. The material is compatible with standard cement-based or polymer-modified plasters used in radiant heating applications.

Technical parameters

Installation and connection

Begin by ensuring the heating pipes are properly spaced and fixed according to the project plan. Apply a base coat of plaster and embed the mesh into it using a trowel. Ensure full coverage of the mesh without overlapping or gaps. Avoid stretching the mesh during application to prevent distortion. Common mistakes include insufficient plaster coverage, incorrect mesh orientation, or failure to secure the mesh around pipe junctions and edges.

Compatibility and accessories

This fixing net is designed for use with IVAR wall and ceiling radiant heating systems. It requires standard cement-based or polymer-modified plaster suitable for radiant heating applications. Additional materials such as corner profiles, edge trims, and expansion joints may be needed depending on the system design and building structure.

Technical background for designers

The mesh operates by distributing mechanical stress across the plaster layer, preventing cracks caused by thermal cycling and shrinkage. The glass fibre material offers high tensile strength and low thermal conductivity, making it suitable for integration into radiant heating systems. The effectiveness depends on proper embedding depth, plaster compatibility, and system design parameters such as pipe spacing and flow rate.

Service and operation

No regular maintenance is required for this product once correctly installed. Check for visible signs of plaster cracking or mesh displacement during routine inspections. If issues occur, repair the affected areas with appropriate plaster and ensure the mesh is fully covered and undamaged.

Frequently asked questions

Can this mesh be used with polymer-modified plaster?
Yes, it is compatible with polymer-modified plasters suitable for radiant heating applications.

What is the recommended plaster thickness when using this mesh?
Apply a minimum plaster thickness according to the plaster manufacturer's specifications to ensure full coverage of the mesh.

Is this mesh suitable for use with underfloor heating?
No, this product is specifically designed for wall and ceiling radiant heating systems.

How should the mesh be cut to fit around pipe bends?
Cut the mesh carefully with a utility knife, ensuring the reinforcement remains intact and covers all exposed areas of the heating system.
