I'm seeing a lot of architects specifications call for a "Industrial grade particleboard core hardwood plywood, 7-ply, 1-inch thick core" for the core of laminate countertops.
Isn't that two different types of core?
Has anyone ever seen this?
I see "confusing" specs from architects all the time. They don't really know what those specs mean, thus they throw in everything they find that they think may be relevant. It is not unusual at all for them to "mix" specs for two or more materials into one spec (like yours).
I have learned over the years not to try to correct them (the architects), most don't take well to someone else correcting their lack of knowledge, even if it's in their best interest and you do it very gently.
In some cases, the request is so ambiguous (or has mutually exclusive details) that you have ask for clarification, but in most cases (like this one) I simply quote what I know will work best for that application and qualify accordingly.
In this case, I'm sure you know that particleboard core will work much better than veneer core (a ply product). I would simply quote as PB core (with appropriate density & thickness) and hope for the best.
Thank you John.
I would not use that product. I think its called classic core but I may be wrong. From columia forest produsts. I would prefer IPB for the core and add a backer if needed. Ply wood will deform badly, but hey I am not the architect. Check AWMAC specs.
Thank you Dave.
