Can you install hardwood floors over osb

So, can you lay hardwood floor over OSB? Not doing so will void the warranty and some OSB boards can have a 50 year delamination warranty. Although hardwood looks amazing, and OSB is definitely a good option. Is it a good idea to lay hardwood over OSB?

As a general rule the major factors that you want the underlayment — the material between the subfloor and the surface — needs to absorb moisture, sound, and provide some cushion. OSB is great for sound, and cushioning. And there are better options. Also, synthetic underlayments like foam are a better option because they provide all the benefits of a softwood like cork, plywood, or OSB.

But, none of the drawbacks such as expanding, and weakening with moisture. OSB will work, however, and will work exceptionally well if it never comes in contact with water.

OSB that has absorbed moisture on the jobsite shrinks as it dries, which can loosen around nails and staples that attach the hardwood flooring. This can result in squeaks and pops when occupants walk across the finished floor. Additionally, wet OSB under drier hardwood flooring can cause moisture to migrate into the hardwood and result in cupped flooring.

If the hardwood flooring is installed with excess moisture, it can shrink and create gaps. Managing Moisture To help ensure moisture content levels are appropriately balanced between the OSB substrate and hardwood flooring, it is crucial to acclimate the hardwood flooring to the interior environment and confirm that the OSB is adequately dry.

Hardwood acclimation; The NWFA recommends that hardwood flooring not be installed or even delivered to the jobsite until the building is enclosed and temperature and humidity conditions match those that will be present once the building is occupied. Some manufacturers recommend even longer.

Some exotic species of hardwood will take longer. The NWFA or manufacturer-recommended acclimation periods provide baseline guidance. Ask the Wood Flooring Guy. Q: I am installing hardwood on our main level. We have a open staircase and railing. Part of the upper level was carpet. I want to remove pro-board and lino in the rest of the main floor and install hardwood over the OSB that was under the carpet.

Can I install hardwood over OSB? I think it partly would depend on how thick the OSB is. When I look at my floor from the basement it is deffinetly OSB. The OSB is the Only floor under the carpet. I would also suggest using glue along the edges and the first couple of rows and the last few rows against the walls. I didn't and I notice it a little bit, but I don't really care that much since I did all the work myself. Indem Sie weiterhin auf der Website surfen bzw. Mehr erfahren. Small-Space Living.

I think this depends on how large the pegged area is. From the picture, it looks like red oak but have someone local look at it in person to confirm. The pegged look and strong bevels are rather dated and most of my customers don't like this look and bevels are hard to keep clean.

If it's a small area, I would rip it up and replace it; if it's large, have the flooring company do an estimate both ways. Usually if my customers can afford it, they'll rip it up and replace it. If they are limited on budget, they'll refinish it You can read about red oak vs white oak in this article.

I was doing testing on the effects of edge swell telegraphing through roof shingles with a couple engineers from major lumber companies way back about , and can even tell you that the edge swelling is not even the major cause of seeing the OSB through the shingles. In fact, I am in the middle of some more documentation on this problem on a 33 year old roof experiment that won't get done until the snow is gone next spring.

I am a general contractor as well as having an electrical license along with other professional licences and credentials. I was doing full engineering calculations for houses that went through the city review department by the time I was I spent several days at several different building departments around explaining to the plan examiners how the engineering hadn't changed from the previous versions of code books when they switched to the ICC codes, but rather they were just missing it before because they were not doing all the math.

Now it is just easier to see because it is in a chart form. I am not old, nor do I live in Texas. I don't even sit at home to do this. It is all done on my phone. Just shows how little you know. What others have said about preparing the surface is good advice. Like 1 Save. You'll have a nice, even and clean surface to install onto, well worth the effort, IMO. Valerie Noronha 15 years ago. I'm crossing my fingers that's what I have for my year old subfloors.

I'm going to bump this old thread back up Does Advantech subfloor take nails better than OSB? The right product for the right application. Boxers is completely correct. Check the grade! OSB is big flakes and strands, of wood going all different directions.
