A short installation guide of wooden countertops and kitchen islands

Solid wood countertops are natural products made of wood from trees approximately 120 years. Wood is a living material along with the more moisture receives, the greater the wood countertop will expand. The wood we found in solid wood worktops may be previously kiln dried to a humidity level of 6%, which is therefore essential that the worktop isn’t exposed to a constantly high level of humidity. Most of the humidity level in kitchens is around 50-70%.

The wood top must be attached to the cabinet box only using wood screws and washers. It isn’t recommended whatsoever to glue the top on the cabinet box; the superior and the box expand and contract at different rates, therefore cracks might eventually appear, most likely on the cabinets’ surface.

The proper way of installing a great wood top is employing metal fixings over the cabinet box (see our web site).
The metal fixings have to be uniformly distributed through the entire length of the top, spaced at the 1′ – 1.5′ distance from the other person. Across the width, the very best is usually fixed to every one metal support with three screws, one inch the middle, one toward leading edge and something toward the rear edge. The supports must be perfectly leveled; otherwise tensions can get in the wood, bringing about warping, cupping, or cracks.
We advise pre-drilling the screw holes in the wood countertop, to counteract cracks and splits. For the same reason, this is a good idea to never over tighten the screws. The finishing will considerably diminish the extent of such movements, but will not get rid of them altogether. Due to panel’s laminated structure, the lengthwise movements are insignificant, so the installer should observe the movements occurring over the panel’s width. In order to prevent the development of inner tensions, the holes inside the metal fixings ought to be elongated toward the movements (see our web page ).

When exposed to normal humidity levels – i.e. 50-60% – the worktop’s width will expand by 1/12”-1/24”, when exposed to a degree of 80-90%, this measurement may expand by up to 1/2″ or even more for many species. Therefore, when the rear fringe of the countertop is installed against a wall, the wall might restrict the top’s natural movements, ultimately causing undesired tensions from the wood. You need to, you can allow a 1/4”-1/2” joint involving the wall along with the countertop edge and caulk it using a thin bid of acid-free silicone.
Additionally, you can firmly fix the back edge towards the metal supports underneath and so, allow the natural movements that occurs at the worth of the opposite edge.
In this case, the holes within the metal fixings corresponding to the rear edge will be no larger than the screws diameter, even though the holes akin to the middle section as well as the front edge will likely be elongated.
