How much does laminate flooring actually expand? I mean 'proper' all artificial laminate, rather than engineered.
The reason I ask is that I will be installing a board parallel (e.g. not at right angles) to a wooden threshold, I would strongly prefer not to have to use one of those threshold cover strips, but if I butt the laminate up with no gap, would it be likely to expand and buckle? This is in a conservatory, so is subject to extreme variations in temperature.
