Lay as one floor when underfloor heating involved

[heathmount]

Hi

I'm going to install under floor heating in my bathroom and I want to tile both the bathroom and the hallway outside. Are there any issues with having the tiles flow continuously between the two rooms or is it advisible to have a profile strip at the doorway due to the potential difference in tile temperature of the two rooms? I don't want to put the ufh in the hallway as well.

thanks

Hi,

You'd need an expansion strip in the doorway whether you had UFH in one room, both, or neither.

Even when tiling a couple of rooms that will probably always be the same temperature, you'd still need a strip. And it is due to the different rates of expansion/retraction just given the fact the rooms wont both have exactly the same conditions and floor sizes.

So yeah, you need some form of a break in the doorway.

As above

if it's all the same type of substrate, would an uncoupler not take up the expansion?

no........

[doug boardley]

what if there's no pre-formed expansion joint in the concrete (assuming it's concrete)?

no........
