Cold Slab And Expansion Of Engineered Joints

We've had an engineered floor installed this past fall and recently it has been pretty cold-in the teens sometimes-and I wonder if the cold will cause expansion of glued-down engineered flooring. I know the installer made some mistakes in a few areas but recently I have noticed an increase of "air" at the end joints of some of the 5 1/2 planks.

Will the cold do this or is it a problem with faulty installation?

Things shrink when the temperature decreases. You can't change physics. Everything known to man expands when it gets hot and contracts when it gets cold.

It sounds like a ventilation and insulation problem with the structure.

That's what I thought. Whew, I won't have to call the flooring store after all.

Will the small gaps disappear when the weather gets warmer-say summertime or will I have to use caulk to seal the gaps?

My guess is, yes. The small gaps should disappear when the weather gets warmer as the flooring expands back to it's originally installed temperature.

So, no, I would not caulk anything... not just yet. Give it a season to learn how it acts in your various temperatures.

Thanks, I'll leave it alone until late spring and see what happens.
