How it is made
A sandwich panel has two metal sheets — usually lacquered or galvanised steel — with an insulating core between them, such as polyurethane or mineral wool.
Benefits
- Thermal and acoustic insulation
- Watertight and durable
- Light weight and fast installation
- Many finishes and colours
- Suitable for roofs and façades
How to choose the right panel
- Required insulation: sets thickness and core type
- Distance between supports (purlins): sets minimum thickness
- Building use: industry, warehouse, agriculture, food
- Fire-resistance requirements
- Finish and colour
Sandwich panel vs. asbestos-cement sheet
Compared with asbestos-cement, sandwich panels offer insulation, lower weight, better watertightness and no asbestos. If you have an asbestos-cement roof, see our roof replacement service.
