Laminate and Wood Flooring Underlay

With the surface suitably prepared, you can start to install the underlay. Unroll the underlay from wall to wall and trim using a sharp knife. Make sure that edges meet but don’t overlap as this will result in an uneven surface. If you are using a damp-proof membrane however, you will need an overlap. Around the pipes it’s recommended that you leave a 10mm gap.


There are many diverse types of underlay that work with laminates including:


The purpose of acoustic underlays is to reduce the transfer of sound through the floor making it a great option for upstairs.


When warmth is your preference, then thermal underlay is necessary. Thermal underlays can offer a certain degree of thermal insulation, keeping your room warmer for longer.

Underfloor Heating

The right underlay is important when it comes to underfloor heating. The wrong underlay can prevent heat from rising through the floor, making your heating less effective. The best underlay is paper felt which allows the heat to transfer through while offering a suitable layer of protection.

Damp Proof Membrane (DPM)

There are some sub-floors which will need the installation of a damp-proof membrane. Concrete is just one example. The damp-proof membrane will prevent moisture from rising through the floor and causing damage to your laminate.

Trims and Profiles

Trims are useful tools that can create a seamless effect across the surface of the floor. Typically, this will involve the gaps between floors that are of different heights such as between a laminate and a vinyl or a laminate and carpet.

Five in One Profile

This product can be used on Pergo and Quickstep floors and is suitable for five different uses. It can serve as a bridge between two floors of the same height, two floors at different heights or make a smooth transition from laminate to carpet. It’s also suitable for use as stair nosing.

Carpet and Tile

Trims should provide a consistent appearance and fit in with the flooring, being part of the surface rather than something that looks like it's been added. These trims can facilitate the transition between thicker and thinner floors.

Pipe Covers

For a more consistent look and finished appearance, you can add pipe covers around radiator pipes. Pipe covers are available in two halves which can be glued together, and they sit loosely on the floor.
