Substrate specification guidelines


Substrate specification guidelines
To avoid any misunderstandings we ask all our clients to read the following recommendations: -
  1. Substrates should be in birch ply. They should be precision made and must be prepared as for painting, accuracy is critical as any irregularities will show in the cladding. All countersinks should be filled and sanded - comparable to a car body panel please.
  2. As the substrate will be used in the forming of the cladding, it must be substantial enough to withstand beating with mallets.
  3. Square section edges must not be radiused.
  4. Dry joints must have both biscuits or similar and a minimum of 2 no. worktop connector bolts.
  5. IF SUBSTRATES ARRIVE WITHOUT BISCUITS OR BOLTS AT THE DRY JOINTS THEY WILL BE REJECTED.
  6. We are unable to correct woodwork defects.
  7. Flaps are not recommended as when clad they are extremely heavy. Further, they are usually left open which affects the patina that develops on the metal. The uneven colour is very noticeable.
  8. Adequate ventilation must be provided for under-bar refrigeration units to prevent heating locally.
  9. Coffee machines tend to heat the cladding locally and may cause damage. Sacrificial pads are recommended and will be made to accommodate services.

Common substrate problems
Most problems arise with curved sections: -
  • Curved plan sections cut with a jig saw can be uneven
  • Fascia not square to curved plan
  • Biscuits omitted from deep fascias
  • Deck not flat
  • Deck stepped at joins
