Section through sandwich panels: metal faces and insulating core

Technical guide

Three components, one system.

A sandwich panel consists of two outer faces and an insulating core, bonded so that they work together under load. This composite action gives a higher load-bearing capacity than the layers would have separately.

A
Outer faces
Pre-painted galvanised steel, pre-painted aluminium or stainless steel; optionally a PVC/TPO membrane or GRP. Rigidity, impact protection and sealing.
B
Insulating core
PUR, PIR or basalt mineral wool. It bonds the faces, provides insulation and adds to the strength of the assembly.
C
Coil coating finishes
Polyester (PE) 20 µm · PVDF 25 µm · Plastisol / PVC 100 µm · Polyurethane 20 µm · Laminated PVC film 120 µm.

Insulation and materials

Insulating cores and metal faces.

The core and the metal face are chosen according to the thermal and fire requirements and the exposure environment of the project.

PUR

Polyurethane

Polymer produced by the reaction of isocyanate and polyol. Provides insulation and adhesion to the faces; light and wear-resistant, for thermal and acoustic insulation.

λ: 0.022 W/(m K)
Density: 38–40 kg/m³
Closed cells: 95%

PIR

Polyisocyanurate

Rigid three-dimensional network with high thermal resistance and better fire performance than PUR; forms a charred layer when exposed to flame.

Reaction to fire: B-s1,d0
Density: 38–42 kg/m³
λ: 0.022 W/(m K)

MW

Basalt mineral wool

Fibrous material made from volcanic rock melted at 1,350–1,400 °C. Thermal insulation, sound absorption and fire class A2-s1,d0. Recyclable.

Reaction to fire: A2-s1,d0
λ: 0.038 W/(m K)
Sound insulation Rw: 30 dB

DX51D+Z

Pre-painted galvanised steel

Hot-dip galvanised with 100–275 g/m² zinc, approx. 5 µm primer and coil-coated in RAL colours.

Reference: TS EN 10346 / TS EN 10169

AW 3000

Pre-painted aluminium

Light, corrosion-resistant and easy to work; tensile strength 175 MPa, temper H16–H26.

Reference: TS EN 573-3 / TS EN 485-2

304

Stainless steel

At least 10.5% chromium; also used in cold rooms for corrosion resistance and hygiene.

Reference: TS EN 10088-2

Special applications

Solutions for demanding environments.

Pitch 2–7%

PVC / TPO membrane

For roofs with a pitch between 2% and 7%. Above 7%, panels with two metal faces are used.

Chemical environments

GRP surfaces

Glass-fibre reinforced polyester, resistant to chemicals, acidic environments and abrasion: livestock farms, poultry houses, food processing.

80–200 mm

MODULIX CS cold rooms

Special joint for sealing and thermal insulation, insulation thickness 80–200 mm, widths 800–1,200 mm.

Colours

RAL groups from the technical documentation.

Metal faces are available in a wide range of RAL colours. On-screen shades are indicative.

Frequently asked questions

Quick answers.

Can't find your answer? Ask us directly

Which sandwich panel thickness should I choose?

Thickness depends on the required thermal insulation and the spacing between purlins. MODULIX panels have 40–200 mm of insulation; for example, a roof panel with a 60 mm PUR core has U ≈ 0.37 W/m²K. The load tables in the catalogue show the span each thickness can carry.

PUR, PIR or basalt wool: which core is right?

PUR and PIR give the best insulation for a small thickness (λ 0.022 W/(m K)); PIR performs better in fire (B-s1,d0). Basalt wool is class A2-s1,d0, also insulates against sound and is chosen when fire requirements are strict.

What lengths and widths are the panels?

PUR/PIR core panels are supplied in lengths of 2,500–13,600 mm and basalt wool panels in 2,500–12,500 mm. The standard effective width is 1,000 mm; some facade panels come in widths of 800–1,200 mm.

Do you deliver sandwich panels across Romania?

Yes. We coordinate sourcing from manufacturers in Turkey, road and sea transport and customs formalities, with delivery in Romania and across the European Union. Availability and lead time are confirmed with the quote.
