Veneered OSB Core6/19/15
We do a lot of flat panel jobs, and I was recently quoted some panels on an OSB core. I had never heard of it. Does anyone here have any experience using this product? Curious to hear about any experience with it. The price is attractive.
I have seen this. Two concerns...all OSB is not the same, so you should get a spec sheet for the OSB, to make sure it does not change from time to time. Even then, there is some poor OSB, so you might want to make sure that you have a well made product. Even then, well made products have different specs and therefore performance.
Second, OSB swells excessively the first time it gets wet, so if the product has a chance of getting wet, you might be very careful.
Another possible concern is that OSB surfaces can have wax and can be fairly unfriendly (rough, for example) for gluing (laminating). Certainly, specifications for the OSB core can help in this respect.
Bottom line is how much of a learning curve and experimenting do you want to do?
One of my clients, bought 4 of these panels, to lock together for a vacuum table and was so disapointed because they were not flat, they cut them up and threw them in the garbage
We got a sample of the "new" OSB core that is being used and had no issues. It is all about the core properties and processes. The OSB plywood we tried was NOT just a piece of stock OSB with a veneer face and back laminated on both sides. I would agree that would be an inferior product. But the plywood we tried had OSB core made specifically for laminating and we had no problems.
I would suggest that you ask questions of the plywood supplier. If they are simply going to Home Depot (or wherever) and buying standard OSB and laminating a veneer face and back on it, I wouldn't touch it. But if a nationally known plywood supplier comes to you with a "new" OSB core made for laminating, personally I would listen.
When particleboard core first came on the general market, it was considered "cheap crap", and people howled about how it would be the end of the industry. That didn't happen, in fact nearly everyone uses the stuff these days. I could see the same thing happening here.
