Class 1 & Class 0 panels

Shadbolt_class_1_and_class_0_veneered_panels

Shadbolt panels can achieve Class 1 or Class 0 flame spread performance without the use of impregnation treatments or intumescent lacquers.

This means that our panels preserve the natural beauty of our wood veneers and ensure a consistent appearance throughout a scheme.

Applications

  • Panels can be used as linings to brick or block walls, in stud partitions, or in proprietary partition systems.
  • Panels can also be used for casings to columns, radiators, ducts etc.

Features

  • Class 1 or Class 0 performance means that panels can be used as wall linings in any location without restriction under Building Regulations B2.
  • Preservation of the natural beauty and variety of wood veneer.
  • Abrasion resistance and durability is equal to standard finishes.
  • The same finish can be provided on doors, frames, non fire-rated panels, trims and skirtings, giving consistent appearance throughout a scheme.
  • Excellent mechanical performance and stability in varying temperature and humidity conditions.
  • Available with FSC® certification as standard.

Construction
Panels have a high-density homogeneous timber particle board with a wood veneer facing. Hardwood edge lippings may be exposed or concealed, square or shaped as required.

Size
All panels are purpose-made to sizes required, up to a maximum of 3000mm x 1220mm.

Appearance
Panels are veneered and factory pre-finished with two coats of clear non-intumescent lacquer, either semi-matt (20% gloss) or high gloss. The appearance is the same as that of a standard panel or door with the same veneer, so that a uniform appearance can be achieved throughout a scheme.

The veneer may also be tinted, stained or limed before lacquering, see Finishes.

Spread of flame
Shadbolt panels achieve Class 1 or Class 0 performance as defined by Building Regulations Approved Document B Appendix A.

These results have been achieved in independent tests and copies of test reports are available. There is an ongoing programme of testing to BS EN 13501-1: 2002.

Class 1 and Class 0 requirements
The locations where Class 1 and Class 0 ratings are required are shown in the tables below, based on Building Regulations (England and Wales) Approved Document B2 Wall and ceiling linings.

The National and European classifications are not automatically equivalent. Products cannot claim a European class unless tested accordingly.
