Wood is a truly unique material: it moves, expands and contracts. You could say it "works". Just like DIY enthusiasts on all of their projects. This organic character is what makes the material feel so welcoming and cosy – and unfortunately, also what makes it so tricky to fasten wooden flooring. The soft boards are not only complicated to install, but also exert extra pressure on the screw connections when they start to move – which explains why flooring so often creaks.
What do I need to know?
Because wood is always moving, you need screw connections capable of absorbing this. After all, even if the dimensions of screw holes and engineered wood boards change, screws must continue to hold the subfloor firmly in place on the floor joists. When fastening solid wood flooring on floor joists or wood subfloors, screws need to be positioned on top of the groove and inserted at an angle. Always make sure you are using the correct head shape to guarantee that the tongue of the next board can slide smoothly into the groove of the previous one.
