Fibreglass Render Mesh

Fibreglass Render Mesh

Render looks great when it’s freshly applied — the real test is how it holds up over time, especially against cracking from movement, impact or temperature swings. That’s where this mesh earns its keep. Embedded within the render layer, it spreads stress evenly across the surface instead of letting it build up in one spot and crack, which makes a real difference to how long a render finish actually lasts.

Made from high-quality alkali-resistant fibreglass, it’s got good tensile strength and flexibility without being difficult to work with. It’s used across new builds, renovations and repair jobs, and being lightweight, it doesn’t add much hassle to the installation process — a useful material whether you’re a professional contractor or handling render work yourself.

What you get with it

• High-strength fibreglass reinforcement
• Alkali-resistant, so it holds up long-term
• Helps cut down on cracking in render
• Strengthens and stabilises wall finishes
• Light and straightforward to install
• Works for interior and exterior jobs
• Compatible with render, plaster and EWI systems
• Suitable for trade and DIY use

The details

Made from durable alkali-resistant fibreglass designed to reinforce render, plaster and external wall insulation systems. Good tensile strength, flexible, and resistant to moisture and alkaline conditions. Holds up across residential, commercial and industrial construction work.

Where it’s useful

External wall insulation (EWI) systems, cement render, lime render, plaster reinforcement, façade renovation, crack repairs, general wall strengthening. Commonly used on brickwork, blockwork, concrete and insulation boards across residential, commercial and industrial builds.

Suitable for both professional contractors and DIY users. It’s the kind of material that doesn’t show once the render’s finished, but makes a real difference to how well that finish holds up.

Why it’s worth having

For reinforcing render or plaster and keeping cracking to a minimum, this mesh does the job reliably. Alkali-resistant, strong, and easy enough to install — whether you’re putting in a new external wall insulation system or repairing existing render.
