Lastra panels are designed with a fiberglass-reinforced composite body; this structure created through a blend of stone powder, special resins and fiberglass provides a much lighter, more durable and more workable surface compared to natural stone cladding.

The panels have defined dimensions: they are produced at approximately 298 cm × 131 cm.
The thickness ranges between 12–20 mm, and the surface relief depth is around 14–20 mm.
With a unit weight of approximately 9–10 kg/m², the lightweight structure offers major advantages in transportation, installation and structural load.

In terms of fire safety, Lastra is classified as A2 non-combustible / limited combustibility, providing high safety for both interior and exterior applications.
Its resistance to high temperatures and stable surface performance make the panel long-lasting and reliable.

The material composition and surface coating are engineered to resist water, moisture, frost and UV radiation. Thus, in outdoor applications such as façades, balconies or garden walls, the panel preserves its form, color and texture for many years. It shows high resistance to impact and mechanical stress; cracking, delamination or deformation do not occur on the surface.

When installed using the screw + anchor mechanical fastening method, Lastra panels can be used across a wide range of architectural solutions — from interior walls to exterior ceilings, column surfaces and niche details. Its lightweight, stone-like structure applies minimal load on the bearing surface while providing an aesthetic, practical and safe cladding alternative.

From an environmental sustainability perspective, Lastra reduces the need for natural stone and the environmental destruction associated with stone quarrying.
Its lightweight nature decreases energy consumption during transport and installation.
Its long service life minimizes maintenance needs and ensures resource efficiency throughout its lifecycle. With these qualities, Lastra is a strong cladding solution that supports sustainable architecture and offers advantages in green building certification systems such as LEED, BREEAM and WELL.

Lastra is a prestigious wall-cladding panel that unites the character of stone with modern building comfort and environmental sensitivity — bringing historical texture into contemporary spaces.
