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
The product’s impermeability keeps the original mechanical characteristics of the wood constant over time, preventing rapid deterioration.
|Type||F / 27|
|Bending Resistance EN 789||MPa||35|
|Elastic-Modulus EN 789||MPa||8.500|
HIGH ABRASION RESISTANCE
Thanks to the plastic overlay the panel displays a high abrasion resistance.

The images demonstrate the nailability of the FIR-STOCK® panel and the absence of splintering, which is common in phenolic film faced plywood.
EXCELLENT RESISTANCE TO CHEMICAL AGENTS
Thanks to its polypropylene based surface, the panel resists cement alkalis and other corroding agents.
SIZES AND STRUCTURE
The FIR-STOCK® panel can be supplied in standard dimensions, and other dimensions are available upon request.

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).
