Layers of laminate flooring

The laminate floor is manufactured  of multiple layers which have been joined together to form sturdy boards. The top most layer is transparent and property to stand up to high wear against scratches, burns, dents and stains. The decorative layer offers a laminatefloor its aesthetic look ranging from wood species to ceramic or stone designs. A core (central) layer, made from high or medium density fiberboard, supports the weight and stress . Strength and stability is further ensured by the lowest stabilizing layer. Lets find out more about these layers.

1. Overlay (The surface wear layer)

The surface layer has a resin-based coating, made of several coats of extremely tough-wearing aluminum oxide or melamine. It is a highly wear-resistant material that gives laminate flooring an excellent size and shape capability, and strength. This top layer is very similar to the layer on counter or kitchen worktops,in fact 40% stronger. It makes the laminate flooring highly resistant to scratches, burns, dents, stains, etc.

2. Decorative layer

This is the name given to the photo rendering of the design which is made to imitate the surface of a natural material, such as real hardwood. Through this layer,patterns ranging from authentic wood reproduction, ceramic and stone designs; give an aesthetic look to the laminate flooring.

3. Core layer

This is the central layer of a laminate floor board that supports the weight and stress of foot traffic. Also called the core board or “carrier board”, it is made up of either medium density fiber-board (M.D.F.) or high density fiber-board (H.D.F.). An M.D.F. is a durable engineered wood product that resists moisture and is saturated in resins to make it extremely hard. This feature helps prevent moisture penetrating the boards.

While the MDF is termed as a bit more structurally sound, the high-density wood core absorbs glue better at the joints. Both materials provide a durable, trustworthy core.

4. Stabilizing layer

The bottom layer is the stabilizing layer.The layer provides strength and stability to the laminate board. It is made up of moisture resistant resins. The laminate is more stable with a laminate or melamine backing than those with paper backings in preventing potential water damage.

Pressure Lamination:

The elements of these four layers undergo one of the following two processes in order to be recognized as laminate flooring:

In DPL (direct pressure laminate) the decorative covering layer and stabilizing layer are pressed together onto the core layer by means of pressure treatment.

In HPL (high-pressure laminate) the decorative paper and overlay are pressed onto an additional layer of high strength paper. Later the layers are glued together by means of high-pressure. This makes the flooring a lot tougher and more resistant to dents etc.

The laminate floor generally manufactured in thickness varying from 6 mm to 12 mm. More the thickness, more durable is laminate floor.

The resulting products can come in thickness varying from approximately 6mm to 12mm, the thicker generally being the more durable.
