Do I Really Need Underlay?

This is a question we’re asked frequently and the short answer is yes if you are laying carpet or wood, no for laying vinyl. There are a number of types of underlay available, the correct choice will depend on what kind of sub-floor you have and the type of room that’s being fitted. Underlay has many benefits besides making carpets feel softer and more luxurious, it’s a step that shouldn’t be skipped or scrimped on. 

Sub-floor Types

As with most things, starting with a good foundation will lead to better results in the long term. Getting the right underlay for your sub-floor will protect and preserve your new flooring, as well as making sure the groundwork is flat and smooth before laying the new floor. Most sub-floors will be either wood or concrete. Concrete bases need an underlay with a moisture barrier, a damp proof membrane (DPM) or a separate barrier to protect the floor from damp.  If the sub-floor is wooden the choice of underlay will depend on what is being laid on top. 

Carpet Underlay

For carpeted floors a layer of underlay has several benefits: not least that it will prolong the life of a new carpet. Underlay acts as a shock-absorber against wear and tear and will prevent the carpet pile from flattening, which can extend the lifetime of your carpet by up to 50%. Underlay also dramatically improves sound and heat insulation, underlay can cut your energy bills by up to 15% and reduce noise by up to 30%! 

Engineered Wood Underlay

As with carpet underlay, having a layer between the wood and sub-floor provides thermal and audio insulation. The acoustics of a room are improved when underlay is used with engineered wood, especially important for rooms in which you play music or cinema rooms. Underlay doesn’t sound proof a floor but it can reduce noise considerably, so is a must for rooms above the ground floor. 

Underfloor Heating

Underfloor heating systems can be used with underlay but you need to select the right type for both the kind of sub-floor and floor that is being laid. Again, there are different types of underfloor heating which require different types of underlay!
