What is a sandwich panel
A sandwich panel is a roof (or façade) element made of two metal sheets with an insulating core between them. It combines weather protection, thermal and acoustic insulation and fast installation in one piece, making it the most common solution for industrial halls, warehouses and farm buildings.

Gutters, flashing and trims: the details that prevent leaks
A roof's lifespan depends on the details as much as on the panel. We fabricate and install custom gutters, flashing and trims, ensuring proper water drainage and watertight joints at parapets, skylights and gables.
Have an asbestos-cement roof?
If your current roof is asbestos-cement, AV Metal handles safe removal and the new roof in the same project. See our asbestos-cement roof replacement service.
Frequently asked questions
What sandwich panel thickness is best?
It depends on the insulation you need, the span between supports and the building use. We advise the right solution after the site visit.
Is a sandwich-panel roof noisy in the rain?
Panels with an insulating core significantly dampen rain noise compared with single sheet or asbestos-cement.
Do you repair leaks?
Yes. We locate the source and repair, or partially or fully replace the roof if needed.
Do you do roofing on new builds?
Yes — new builds and refurbishment, including the supporting structure where applicable.
