Thermoplastic ventilation grill GRIGLIA ANTIVENTO GRF

polypropylenesquarefor outdoor use

Product overview
GRF Windproof Grid by Eterno Ivica is a polypropylene panel designed to secure porcelain slabs on raised-deck installations and to resist wind uplift. It is the central element of the Windproof System GRF, ensuring stable, fixed tile placement for exposed outdoor surfaces.

Construction and formats
The grid is manufactured in polypropylene in a nominal 600 x 600 mm format with a height of 28 mm. The component integrates an adhesive guide for consistent application and built-in joint spacers, reducing the need for additional accessories. Page metadata also references an alternate panel size of 500 x 500 mm and a 40 mm height in a black thermoplastic material.

Advantages

• Resistance to wind-induced uplift for safe exposed surfaces.
• Improved load distribution through positive anchoring of the slab to the grid.
• Protection against breakthrough to maintain long-term flooring reliability.
• Integrated joint spacers remove the need for separate spacers.
• Compatibility with all Eterno Ivica supports.
• Accurate and uniform laying using the integrated adhesive guide.

System components

• Windproof grid: 600 x 600 mm polypropylene element that receives and secures the slab.
• Locking plate and safety screw: placed between grids at each corner to ensure system stability.
• Adhesive: applied via the dedicated guide to bond slab to grid.
• Support: adjustable pedestal base on which the system rests.

The locking plate
The locking plate is inserted between adjacent grids at each corner to stabilise the windproof assembly. It can be fixed to the support with an optional safety screw for additional stability; the screw may be installed later through tile joints without dismantling the decking.

Quick and easy installation

• Position and adjust supports: place pedestals on the installation surface and set required height.
• Secure slabs to grids: lay grids row by row and bond the slab to the grid using adhesive applied along the integrated guide.
• Insert locking plate: once grids are positioned over supports, insert locking plates between grids at every corner.
