A client is asking if we can specify solid wood cabinets, with the idea that particleboard or MDF cannot be durable enough for K-12 school projects. My understanding is that MDF would be more durable than particleboard, and that there is not even a place in MasterFormat for solid wood cabinets, so they must not be used all that often anymore. Does anyone else specify solid wood cabinets? Suggested # & title? Or any thoughts on specifying good durability if MDF is used? We have sometimes specified exterior grade plywood instead for countertops in potentially wet locations like at sinks. |

I’d contact AWI for an answer to this question. |

Another option I'm now thinking of is all cabinets/countertops are veneered or PLAM over plywood -- so just eliminate MDF and particleboard or only allow the for backs, drawers, etc. Then a new spec section is not needed. The original question is still of interest to me though. |

I saw a solid wood cabinet once. It was hewn from a single block of wood. Of course you can specify it. Michael Chusid, RA FCSI CCS 1-818-219-4937 www.chusid.com www.buildingproduct.guru |

Chris, are these cabinets MDF with PLam of just solid MDF? There's some neat powder-coat finishes available that may add to the durability of exposed MDF but it's not cheap. I would expect PLam over MDF to be much more abuse-resistant than solid wood unless they're willing to pay a lot for thick, solid lumber that won't split over time. Think about the costs for jointing, sanding, and finishing. Besides, the Architect will need to detail what they want. Do they know what they're doing with that? As for PLam over plywood, most fabricators don't like that because PLam likes to delaminate from plywood. As for marine grade plywood at wet areas, I do specify that but prefer going solid surface at that point. I'd be curious to see the cost difference. I suppose you can use bolted plywood, screwed and glued to solid blocking, but then you're going to end up with kids getting lots of splinters. |

The client says MDF is fine just not particleboard. And to use MDO plywood for the shelving. |

Sounds reasonable. MDO takes paint better than most veneers. |

In addition to sinks, other potentially wet areas are the bases/toe kicks. Solid lumber or other wood that won't swell is something to consider specifying for these locations, even if the rest of the cabinets include typical composite wood products. |

We have clients who want Wood Veneer Cabinets referred to by some as solid wood cabinets. "Solid wood is lumber that has been milled directly from trees. Other types of wood, such as plywood, medium-density fiberboard or veneers, are manufactured from wood composites." |

Ha. Depends entirely on what definition of "durable" is being used. Dimensional stability in the presence of fluctuating RH? - MDF is the clear winner. Ramming a library cart into a base cabinet at full teenage sprinter speed? Who knows - what is the ASTM test standard for that?? kinda silly to say solid wood is better without having even the slightest bit of evidence to back the statement up. You'd be better off NOT acquiescing to this request due to the potential negative consequences in using "soild" wood, IMO. |

It seems to me that making sure you have durable casework is the goal. However, getting there by selecting materials may not work. Lot's of things can still go wrong: the hardware or the joinery may be insufficient, shelving too thin for the span, drawer slides inadequate, etc. What you should strive for is performance. The Architectural Woodwork Standards include requirements for casework integrity. Also, SEFA, for lab casework, has durability standards. Also, regarding plam vs. wood veneer. I don't think it's clear cut that plam is more durable. If it chips or is scratched, it may show more than wood veneer. Wood is somewhat repairable, plam is totally not. Laminates for the edging can come loose (I'd usually spec rubber edging for durability). I'd call AWI for advice, although they'll also push their quality inspection service. You may want that if there's a lot of casework involved. |

Section number and title? 664100 Architectural Wood casework. No need to drill down to children. Or can back-drill up to 064023 Interior Architectural Woodwork. |
