Laminate over pier and beam
Hi all,

I'm getting ready (hopefully ordering in the next few days) to install Quickstep laminate in about 400 square feet (Living room and hall) of my house. I tried to get you all the info you usually ask for off the bat :D

I live in the northwest and have pier and beam construction, house was built in the late 70s. No ongoing settling issues that I'm aware of (few small cracks in the outer perimeter concrete that haven't changed in 5+ years). Joists are 24" OC 2x10 or 2x12 (If it's important I can crawl under the house and measure), and the subfloor is 2x8 tongue in groove lumber with 1/2" OSB or Particle Board (not sure how to tell the difference) stapled to the 2x8s. There is a moisture barrier between the joists and the subfloor. The underside of the house is insulated.

The main question I have is that in the Quickstep video, they briefly show moisture barrier, then a plywood underlay, then a pad, followed by the laminate. That seems...excessive...based on my construction, and I can't find anything that looks like that in their written directions (which are awfully brief).

Thoughts on what I need between the 1/2" and the laminate in my situation? Apparently this construction style isn't common outside the NW and it's dang hard to find information...

Thank you!

Particleboard and OSB have distinctive looks. It's not hard to tell them apart. See the pictures below and look at the file names (hovering over the pic will reveal the file name).

Since you already have a moisture barrier, you do not need a second one. The pads for laminates come in a large variety. You don't need one with an attached moisture barrier. But you may prefer to have one that helps give the laminate a more solid sound when walking on it. Many people complain about the sound coming from laminate flooring. Those cheap foam pads don't muffle the sound well. I've been away from sales and installation long enough that I can't give you a good recommendation, but some of our other members can.

Ahh ok, now that I see the pictures I know the difference. It's particle board (if that makes any difference).

I'm definitely open to recommendations on what kind of pad to use!

Thanks for the fast response!
