Gaps in Engineered Timber Flooring Perth
Engineered floors are designed to minimize gaps, but no material will eliminate gaps entirely.
Engineered timber planks are comprised of several layers of different timber. The top layer is chosen entirely for an attractive appearance. The sub-layers are used for stability and strength. These multiple sub-layers are arranged in a criss-cross pattern. The grain of one layer is set 90 degree to the grain in the next layer. This helps improve stability as any expansion in the floor material will not be one direction.
An ordinary piece of timber will expand when exposed to moisture and heat. This expansion will be across the grain. So if the grain runs north to south the expansion will be east and west. A timber floor should be installed to accommodate this inevitable expansion in changing conditions. gaps are left between boards and at the edge of the room to allow some expansion.
The engineered floorboards have much less expansion than solid timber. This is because the expansion inherent in one layer pulls in a different direction to the expansion in the next layer, because the grain run in a different direction. Nonetheless a small amount of expansion will occur.
Reducing expansion problems.
Many installers will insist on leaving the timber to acclimatize in the room for a few days before installing. This means the timber will expand or contract slightly according to the conditions of that particular room. If the room stays roughly under the same conditions the timber boards in the floor should stay roughly the same.
Of course thee will be at least some changes in weather conditions, so the floor will expand and contract slightly. Engineered floors will only suffer slight changes compared to solid timber, but we must still make allowances for this.
We should leave a gap around the edge of the floor to allow expansion. This gap is covered by the skirting board. A 2 cm gap is usually fine.
Individuals floor boards are fairly straight, but never perfectly straight. So the installer should try and match each board so that it fits with the neighboring board; the sides should be neatly parallel. Installers should also leave some slight gap between boards to accommodate expansion. The tongue-and-groove edges on the boards that lock the floor together means the gap will not be deep, not decend to underneath the floor.

Whether floating or fixed to the sub-floor the engineered timber floor will be relatively stable if installed correctly. Using air-conditioning and humidity control will allow the conditions in the house, the temperature and humidity of the air, to be stable, which greatly helps the floor to stay neat and flat.
