Supply and fit-out of sandwich panel systems for roofs, facades, walls, and cold rooms, with EPS, PUR/PIR, and rock wool insulation options according to the intended use.
This sector supplies and fits sandwich panels used in roofs, facades, walls, cold rooms, warehouses, hangars, light buildings, and fast-build units. The content of this page is shaped by reviewing catalogs from specialized companies in the same field to understand common product lines and practical specifications.
The core idea of sandwich panels is combining two outer metal sheets with an internal insulation core, giving the panel good rigidity with low weight and improved thermal and acoustic performance. This makes the solution suitable for projects requiring fast installation, a clean industrial appearance, and better insulation than traditional cladding.
We help clients select panel type, insulation thickness, metal sheet type, accessories, and fixing method according to project use: warehouse, cold room, industrial facade, hangar roof, or an operational unit that needs quick installation and future serviceability.
Panels designed for insulated metal roofs, helping water drainage while providing surface rigidity and fast installation on purlins.
Used for external and internal wall cladding, with choices between flat, ribbed, or concealed-fixing appearances for a cleaner finish.
Panels with larger insulation thicknesses and tighter joint details for spaces that need temperature control, reduced air leakage, and lower energy loss.
The insulation core is selected by priority: economy and light weight, fire and acoustic performance, or high thermal performance for cold rooms and insulated roofs.
When a softer appearance closer to wood or stone is required, decorative panel finishes can be used for field offices, prefab units, and selected service facades.
The range includes 3-rib and 5-rib roof panels, facade and wall panels, concealed or capped fixing panels, cold room panels, and decorative options such as wood or stone pattern finishes when available from the manufacturer.
The choice depends on function. EPS is suitable when economy, light weight, and fast installation are the priority. Rock wool is suitable where fire and acoustic behavior are more important. PUR/PIR is typically selected when thermal performance, panel thickness, and energy control are critical, especially in cold rooms.
A sandwich panel system is not complete with panels alone. Accessories control corners, edges, joints, and help reduce water and air leakage. Ridge caps, edge caps, internal and external corners, flashings, and screw types are selected according to building shape, water flow, and wind direction.
| Item | Common values | Selection note |
|---|---|---|
| Useful width | Often 1000 mm | Depends on joint system and manufacturer. |
| Minimum length | Around 2.4 m in some systems | Longer lengths depend on transport and handling. |
| Roof and wall panel thickness | 30 / 40 / 50 / 60 / 80 / 100 mm | Selected by insulation need, spans, and budget. |
| Cold room thickness | 50 / 60 / 80 / 100 / 120 / 150 mm | Higher insulation needs generally require greater thickness. |
| Approx. PUR density | Around 40 ±2 kg/m3 | Always confirm in the final quotation. |
| Metal sheet | Painted galvanized steel or aluminum depending on availability | Common sheet setup in some systems: 0.50 mm top and 0.40 mm bottom. |
| Panel type | Best use | What we review before supply |
|---|---|---|
| Ribbed roof | Hangars, warehouses, workshops | Slope, purlins, wind and rain direction, transport lengths. |
| Wall/facade panel | Industrial facades, units, partitions | Fixing, corners, openings, final appearance. |
| Cold room | Food, medicine, healthcare, chemicals | Temperature, thickness, joints, doors, floor. |
| Rock wool | Areas needing higher fire and acoustic behavior | Required rating, load, and moisture protection method. |
We define whether the project is a roof, facade, cold room, warehouse, or prefab unit.
We compare thickness, core type, sheet type, and fixing method with budget and required performance.
We define flashings, corners, ridge caps, screws, and joint details before ordering.
Coordinate lengths, quantities, and deliveries according to transport, installation, and site sequence.
