Product Overview

Traditional wood or metal louvres are expensive to install and rot or rust when exposed to the elements. We created a stone-based ribbed panel that gives you that architectural grille look without the maintenance headache. This solves the durability problem for exterior louvre designs.

The 1200x2400mm panels feature parallel ribs with a 2.5-4.5mm thickness. This grille-like pattern is perfect for adding verticality to a building's facade or interior feature walls. We offer this in all our standard mineral colors to match your palette.

Exterior Facades & Columns

Lightweight facade cladding on commercial buildings, architectural columns, and archways where the panel weight and flexibility change what's buildable.

Installation notes for Ribbed Panel

1. Prepare the substrate

For Ribbed Panel, use a sound, dry and clean wall. Remove loose finishes and correct dampness before bonding the 2.5-4.5mm flexible stone panel.

2. Dry-fit the first panels

Check the 1200*2400 layout around openings, corners and trims before bonding.

3. Apply stone adhesive

Use the specified polymer-modified stone adhesive with a notched trowel. Press the panel firmly and keep the adhesive bed continuous.

4. Seal exposed edges

On outdoor or wet-area work, seal cut edges and panel joints with a compatible flexible weather sealant.

Final adhesive, substrate and sealing decisions should follow the project specification and the supplied technical data sheet.
