Roundtower’s Glass Fibre Meshes offer high-performance crack prevention and reinforcement for both building conservation and contemporary plaster/render systems. Suitable for interior and exterior use, these alkali-resistant meshes are especially effective when working with lime mortars, traditional substrates, and insulation systems.
This mesh is ideal for absorbing and dispersing stresses caused by temperature changes, movement, and curing—all while minimising cracking and mechanical damage.
