Wooden Flooring Explained

If you're new to wooden flooring, then getting your head around the technical terms can be a bit confusing. In this hub we look at some of the mumbo jumbo and explain it real terms. This hub is brought to you by - A professional flooring services company in Nottingham.

Damp Proof Membrane

A Damp Proof Membrane or DPM, is plastic or foam sheeting that is placed over concrete, sand, or cement floors before laying wood or laminate floor boards. The job of the DPM is to prevent dampness transferring from the original subfloor to the wood, preventing it from warping or swelling.


Underlay works in the same way as a DPM, however is used on wooden subfloors like floorboards. It creates a layer of cushioning, to both improve the feel of the new wooden floor and provide sound insulation. An absolute must if you are laying wooden or laminate floor in an environment where there are further rooms below.



Screed is a plastic or latex substance which is applied to an uneven floor as a liquid. The liquid is then leveled out before drying to create a even and level subfloor before fitting a new wooden floor.

Expansion Gap

Wooden flooring expands in damp and humid conditions, so it is important to allow room for the flooring to 'breathe' An expansion gap is usaully between 5-15mm depending on the type of flooring and environment in which it used, and allows the wood to expand in the event of changeable conditions.

Tongue And Groove

Tongue and Groove refers to the method which laminate and sometimes engineered board affixes together. Each board ha 2 differing edges, the tongue side features a protruding ridge, which slots into a corresponding groove on the alternate side of the adjacent board. This created an interlocking system which prevents the boards from shifting around.
