Description
Ordinary roofs are often simply plastered with cement and mortar. Temperature changes and wall settlement can easily lead to cracks, and over time, the surface layer can become hollow, peel, and leak. Roofing mesh, on the other hand, acts as a reinforcing layer, firmly holding the mortar layer together, distributing tension, and effectively preventing roof cracking and peeling, thus extending the roof's lifespan.
Miniature cracks in the roof are a major cause of leaks. Rainwater seeps into the roof and walls through these gaps, causing mold growth on interior walls, peeling paint, and water seepage from the roof. Laying a layer of roofing mesh reinforces the overall structure, seals these tiny cracks, reduces roof leaks at their source, and provides more stable waterproofing.
Differences in specifications and sizes of roof nets
The specifications and dimensions of roofing mesh vary depending on the material and intended use. Below is an introduction based on the wire diameter, mesh size, and dimensions:
Wire Diameter
It's not recommended to choose a wire diameter that's too fine; generally, 0.8-1.2mm is recommended. If you want a more secure roof, you can choose a thicker wire.
Mesh Size
Common mesh sizes are 15×15mm, 20×20mm, and 25×25mm. The appropriate mesh size can be selected based on the thickness of the concrete.
Size
Generally, it's custom-made based on the roof's dimensions, but widths up to 3 meters are possible. You can also purchase rolls and have them cut to size.
Waterproof and thermal insulation effects of roof net
Roofing mesh is also very important for waterproofing and insulation, especially in rural areas. Heavy rain can cause water to leak into the house, causing inconvenience. In cold winters, the house can also be extremely cold. Roofing mesh can be helpful in these situations.
• Waterproofing: The mesh structure efficiently drains water and traps debris, effectively preventing water infiltration caused by clogged drainage channels.
• Insulation: It remains flexible even at -30°C, preventing freeze-thaw cycles that can cause cracking and failure of the insulation layer. Combined with adhesives, it ensures a tight seal in extremely cold regions.
Roof netting also protects against small animals, such as those that nest on rooftops, which can damage the roof over time.
What should we pay attention to when installing roofing mesh?
Material Inspection: Check that the specifications meet your requirements and verify the quality, including ensuring the mesh is free of rust, secure welds, and a tight weave.
Supplementary Materials: Wire tie wire or special clips for mesh overlaps, as well as other installation tools.
Mesh Installation: Different mesh types require different installation methods. For concrete roofs, the mesh should be positioned in the upper middle portion of the concrete layer, ensuring it is completely enclosed. Secure with concrete nails to prevent the mesh from buckling during concrete vibration.
If the roof of your home is made of other materials, if you want to install a roofing mesh, please consult customer service for details.
