FR (B-s1,d0) composite panel for facades

Aluminum composite panel with a fire-retardant mineral core and a fire reaction rating of B-s1,d0 (EN 13501-1). Es el panel más usado en fachada ventilada, rehabilitación de fachadas, marquesinas, revestimiento de columnas y rótulos de gran formato.

  • Fire-Retardant Mineral Core
  • Fire reaction class B-s1,d0
  • Thicknesses: 3, 4, 5, and 6 mm
  • Sheet size: 1,500 × 5,000 mm

FR Core

The most commonly used core for facades

Its thermoplastic core with mineral filler is fire-retardant: it has very limited combustibility, produces very little smoke and releases no flaming droplets, which is why it covers most ventilated facades where a non-combustible material is not required. Available in 3, 4, 5 and 6 mm. We supply it cut, milled and folded to size, ready to install. We install in Catalonia and ship worldwide.

On facades, 4 mm is the usual thickness; 3 mm is used for cladding and signs, and 5 and 6 mm where large pieces need extra stiffness. It is lighter and slightly more economical than A2, accepts every fold angle (90°, 135° and 180°) and can be roll-curved. At StarModul we help you choose the thickness and mounting system and machine every piece in our workshop on CNC equipment.

What is the FR panel used for?

  • Ventilated facades in new construction and renovation projects, with suspended, riveted, or gluedmounting systems.
  • Cladding for columns, canopies, overhangs, parapets, and balconies.
  • Corporate branding: facades of dealerships, gas stations, and retail stores.

If the project requires a non-combustible material, use the A2 composite panel.

Machining

FR is cut, milled, and bent (90°, 135°, and 180°) to make trays, and it can be curved using rollers. We do this in our workshop using CNC machines: see our machining services.

Frequently asked questions

What does B-s1,d0 mean?

This is the fire reaction class according to European standard EN 13501-1: very limited flammability (B), very low smoke emission (s1), and no falling burning droplets (d0).

What thickness should I choose for a facade?

The most common thickness for facades is 4 mm. The 3 mm thickness is used for cladding and signs, and the 5–6 mm thickness is used when greater rigidity is needed for large pieces.

How much does the 4-mm FR panel weigh?

Between 6.8 and 7.3 kg/m², depending on the thickness of the aluminum sheet.

How much does it cost?

As a general guide, composite panels cost between 40 and 60 €/m² depending on thickness, finish, and quantity. Our quote will break down the costs for materials, fabrication, and shipping. Request a quote.
