The FIR-STOCK® panel is a formwork produced in two traditional thicknesses: 21 mm and 27 mm, 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.

|Bending Resistance EN 789||MPa||40||35|
|Elastic-Modulus EN 789||MPa||10.000||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.
