Quick Question RE Hardwood Installation

[babyruthie]

Hi -

Still doing some research on installing the floor. I was listening to an online demo on laying a floor - and this one site suggested starting in the middle and then putting the groove to groove with a piece of tongue/molding in there to hole it and laying the floor in opposite directions towards the wall. I think it said that this was beneficial for expansion??

Is this true - is this something we should consider - it said for rooms over 13-14' W, Ours is around 12+

This molding/slip-tongue will also be needed for us when doing our transition pieces - there will be some spots that need the tongue to fit into the transitions. Where do I buy them - is it just molding?? Any suggestions on sizes?

Thanks...

Because of the angle of the fastener, the wood pushes against the path of least resistance. Splitting it with a spline/slip-tongue, makes the expansion force happen in opposite directions from the center. It helps, but is not the save all.

Supposedly it helps somewhat on floors that are fastened down..... it would nothing for a glued down installation. Also if you go that route you will now have two end walls to deal with as opposed to just one.
