CHARACTERISTICS

FIR-STOCK® panel is a formwork produced in 27 mm thickness, externally covered with a plastic overlay.
The polyolefin based plastic overlay allows a perfect, uniform, smooth, and impression free concrete finish, improving the result of the traditional three ply spruce panels:

  • Abrasion resistance is considerably higher
  • When nailed does not splinter
  • Less release oil is needed
  • Faster cleaning with high pressure water
  • Panel’s lifespan increases considerably

RECYCLABLE

The FIR-STOCK® panel consists of birch plywood core overlaid with a polyolefin based plastic sheet. A study has shown that it is possible to re-use the FIR-STOCK® panel at the end of its lifecycle. The panel, ground down with other materials, has been used as material to manufacture some products as shown below, injected with an open mold using Plastech technology (read more).
