Product Description

Alucrownstone is a fabricated stone panel wall cladding system utilizing a composite panel made by laminating a natural stone layer to an aluminum honeycomb panel with aviation grade epoxies.
Alucrownstone is fabricated and then attached to the wall with a series of aluminum extrusions.
Alucrownstone can feature a large range of natural stone finishes, including granite, marble, limestone and sandstone. The natural stone composite panels are suitable for interior and exterior use, being highly weatherproof and suitable for high impact areas.

Why use Crownstone over traditional solid stone??
1,Lightweight-Crownstone is only 1/5 of the weight of its equivalent in traditional stone. This means that the product is much easier to handle and to ship, lessening damages, and improving onsite efficiency and safety.
2,Simpls installation-Crownstone offers far improved attachment over traditional solid stone. The solid stone anchoring system exposes the weakest properties of the stone, whereas the fixing systems offered with Crownstone are rapid and align with common systems already used in Australia.
3,Flexibility-Alucrown panels, using stone as a veneer over the honeycomb core are much flexible than dimensional stone. As a result the panels are much less prone to fracturing and cracking and better able to withstand building movement and extreme weather events.
4,Stability-The thin stone found on Alucrown panels lack the torsional force the thicker traditional stone. This means the lightweight Alucrown systems doesn't experience the stability failure that occurs in traditional stone.
