# Click LVT expansion gap for small room

Posted 6th Mar 2020
How much of an expansion gap is required for a small room when fitting CLICK LVT?

Looked online and the videos say 5mm all the way around the edge but the floors space in the videos is a lot bigger than mine.

My room size is 1.40m by 2.60m (bathroom).

Please can someone confirm if I should still have a 5mm expansion gap or smaller.

1. You'll be able to get away with a smaller gap as the room is small. The coefficient of expansion is essentially a ratio - so if 5mm is sufficient for a 5m meter run, in theory a 1mm gap is sufficient for a 1m length (however practically you may need something larger).

Also - in a bathroom your not likely to get great temperature difference compared to a conservatory for example.

For example if a room is 5m by 100m it would not mean that the expansion gap has too be increased from 5mm too it 100mm that theory doesn't seem correct.

It was correct when I went to university to study my engineering degree and as far as I'm aware the laws of physics haven't changed since then.

If something which is 1m long expands to 1.001m when the temperature increases from x to y, then 100m of the same material would expand to 100.1m for the same temperature increase. This is why we have expansion gaps between rail track at every joint, rather than just a gap at each terminus railway station.

For a large floor, an expansion joint (or several) in the middle would be required, not just a 5mm gap around the perimeter.
3. Yes 5mm still it doesn't matter about room size as it's for the laminate too expand and contract too big a small a gap and it could Push the laminate up and lift it up when it expands. 5mm isn't really that much anyway is it

Its click type LVT

Its click type LVT

Which brand? What do their guidelines say Is it going up to the skirting or under it? Are you going to put silicone etc around the edge. No point having a gap in a wet bathroom and ruining your LVT from the bottom up.

So if a room is 5 metre by 6 metre the gap is still 5mm on each edge?

I just thought a smaller space would lend itself to a smaller expansion gap than a bigger space.

Its Tegola from carpet right. Its going in a bathroom which is tiled from ceiling to floor and has no skirting. Was going to use silicone where wall meets floor.
8. It is made by Moduleo. They have an installation guide here: moduleo.co.uk/sit…pdf

REQUIRED EXPANSION GAP • Moduleo® Click is a “floating” floor. The panels should not be glued or fixed to the subfloor below. • A 5mm expansion joint must be incorporated at the perimeter of the room/area.

Get it from a different place will be a cheaper same stuff.

Ok I didn't realize would see thought as each peice is separate the size of approximately 5mm is adequate. Good job as I am thinking of laminate for a Room 5M by 5m , what size gap will I need and how do I put a good in the middle won't the board's get damaged.
