CB T&G Floor combines the basic qualities of Repo by Sorbes Chipboards (see CB) with a tongue and groove profile, offering a really practical solution for laying subfloors.
Main uses:
- Efficient construction of load-bearing subfloors in commercial and residential applications
- Just as suitable for new constructions as for the renovation of timber houses, cottages etc.
- Stable joints, with a completely smooth surface, forming a perfect substrate for parquet, linoleum, carpeting etc.
Ergonomic and practical features:
- Ideal heat and noise insulation characteristics
- Strong P4 board (load-bearing; higher-quality values for bending strength, internal bond and elasticity comparable with type P2)
- Boards with good holding strength of screws
- Special sizes for easy laying by one person
