'Engineered' refers to the timber plank's construction. Engineered timber planks consist of multiple layers, opposed to solid timber which is one single 'solid' plank of wood.
Engineered timber is designed to be more stable than traditional solid timber planks. More stability ensures the flooring is less susceptible to cupping, bowing and warping.
This style of flooring works so that the grain runs perpendicularly, giving the flooring much more strength & stability - making any expansion or contraction with changes in different weather conditions. This type of timber is perfect for Australian building projects due to the volatile climate.
