This is the strongest construction of engineered wood on the market and can be placed on any type of subfloor, as well as underfloor heating. As the name suggests, it is made using multiple layers of ply wood, which are tightly fused together and then topped with a layer of real wood veneer.
As the same suggests, three-ply consists of 3 layers of plywood, tightly fused together and then topped with a layer of real wood veneer. Because it contains fewer layers than the multi-ply, it is a slightly cheaper option. However, it still provides great strength and can also be laid on any type of sub floor.
HDF or High Density Fibreboard, is a very hardy material and is the core layer used in this particular type of engineered flooring. As with all engineered flooring, it is topped with a layer of real wood veneer. The HDF core makes for a very robust floor, which can withstand heavy foot traffic. Although this type of engineered can be laid on any type of sub floor, HDF can act like a sponge if it is repeatedly exposed to moisture. Therefore it is not a good option if you are renovating a room with high levels of moisture.
