This standard 21/30438582 DC BS EN 14509-2. Double skin metal faced insulating panels. Factory made products. Specifications is classified in these ICS categories:

• 91.100.60 Thermal and sound insulating materials

This document specifies characteristics of factory-made structural double skin metal faced insulating sandwich panels for use in elements for structural applications in roofs, in external and internal walls (including partitions) and in ceilings in buildings (hereafter referred to as structural sandwich panels).

The sandwich panels consist of two faces and insulating core either by using an auto-adhesive bonding technique or by using a separate adhesive layer.

The face materials covered by this document are:

1. steel,

2. stainless steel,

3. aluminium,

   NOTE

   Aluminium covers aluminium alloys.

4. copper

The insulating cores covered by this document are:

1. rigid polyurethane (PU) (see 3.1.15);

2. expanded polystyrene (EPS) (see 3.1.13);

3. extruded polystyrene foam (XPS) (see 3.1.14);

4. phenolic foam (PF) (see 3.1.12);

5. mineral wool (MW) (see 3.1.11).

For sandwich panels the coating of faces can be either organic and/or metallic coating.

This document specifies procedures for assessment and verification of constancy (AVCP) of performance of characteristics of sandwich panels.

This document does not cover the following:

1. sandwich panels used for stabilization purposes having insulation core material of phenolic foam;

2. sandwich panels consisting of two or more clearly defined layers of different insulating core materials (multi-layered) or of materials per face;

3. curved sandwich panels;

4. perforated sandwich panels;

5. sandwich panels used as ceilings when fastening is under permanent tension load;

6. special type of fastening such as ‘T’ support for ceiling, threaded rods with clamps for wall, omega and clamps for wall and ceiling, injected joint with flashing and threaded rods for wall and ceiling;

7. fasteners;

8. sandwich panels, placed on the market as a part of clean room kits, conditioning room kits, cold storage room kits and cold storage building envelope and building kits.
