Do I need underlay for luxury vinyl tiles?

So, you’ve decided to install Luxury Vinyl Tiles (LVT). Good choice! They look fantastic, are durable, easy to maintain and reasonably priced. But do they require LVT underlay? It’s a question we get asked time and time again – here at Carpet Underlay Shop – and the answer is a lot simpler than you might think.

A general rule-of-thumb for LVT underlay

It all depends on the type of LVT you have bought. Whilst some tiles come with an in-built layer of cushioning, others don’t – for these, LVT underlay is usually a worthwhile investment.

It’s also important to consider the thickness of the LVT. As a general guide, tiles that are less than 4mm thick shouldn’t be installed with underlay, as it can have a negative effect on the strength of the ‘click’ mechanism. However, for tiles that are 4mm thick (or more), LVT underlayment has a number of benefits and can help to improve the overall performance of your new vinyl flooring.

Reasons to invest in LVT flooring underlay

  1. Noise reduction

LVT underlayment has excellent acoustic properties. Made from high-density foam, it’s designed to absorb sound and will reduce noise by approximately 16-20db.  This can be particularly useful if you live in an apartment building or flat and do not wish to disturb the neighbours.

  1. Improved comfort

By adding an extra layer of foam between the tiles and subfloor, LVT underlay can significantly improve the comfort of the tiles – making them much softer and warmer underfoot.

  1. Stability

Luxury vinyl tiles usually just click into place. An adhesive isn’t required, which makes installation very easy – but it also means there’s potential for the tiles to move over time. Underlay is a great way to prevent this. Sandwiched between the LVT and subfloor, it’s foam texture stops any unwanted movement and can help to keep the tiles securely in place.  

  1. Moisture protection

Before fitting LVT, it’s important to test the relative humidity of the subfloor and make sure it falls below 75% – as dampness and moisture can cause the tiles to lift, curl and crack. If you think moisture will be an issue, it may be worth adding LVT underlayment. Most have an integrated damp-proof membrane and can help to reduce the risk of moisture accumulating beneath the tiles.
