Penguins Fibreglass Mesh is a critical component in External Thermal Insulation Composite Systems (ETICS) and is widely used in:
Residential and commercial facade insulation projects
Systems using EPS or mineral wool insulation boards
Areas prone to structural stress, thermal movement, or surface cracking
High-performance EWI projects requiring certified and long-lasting materials
Ideal for:
Insulation contractors
Building envelope specialists
Construction firms focused on energy-efficient facade solutions
By integrating IS165 into your insulation system, you ensure superior resistance to cracking, better stress distribution, and a longer lifespan for your facade.
Before Installation:
Ensure the insulation board surface is clean, dry, and free of dust.
Prepare your reinforcing adhesive according to the system manufacturer’s instructions.
Embedding the Mesh:
Apply a base coat of adhesive evenly using a notched trowel.
While the adhesive is still wet, press the Penguins Fibreglass Mesh into the surface using a stainless steel trowel.
Overlap adjacent strips by at least 10 cm to ensure structural continuity.
Smooth out any wrinkles and ensure the mesh is fully embedded and not visible.
Apply a second layer of base coat (wet-on-wet) to cover the mesh completely.
Allow to dry before applying finishing render or topcoat.
Storage Tips:
Store in dry conditions, off the ground, and protected from direct sunlight.
Avoid contact with water prior to installation.
