A Carpenter's Guide to Specifying Board

Written for the trade: board selection by application, thickness by span, edge treatment, hardware compatibility, and the questions worth putting to a supplier before ordering.

This one is written for the trade rather than the homeowner. If you are specifying board for somebody else's kitchen, you are carrying the risk of the decision — the customer sees a finished kitchen, and any failure two years out is your phone that rings.

Specify by load path, not by material preference

The useful question at every component is what is actually acting on it.

Things carrying weight across a span — shelves, cabinet bottoms, anything with a rail in it. Plywood, 18mm, and add a rail beyond about 600mm of unsupported span. Deflection is a function of span, thickness and load, and it does not care how good the sheet looked in the yard.

Things taking a repeated mechanical fixing — hinge plates, runner fixings, rail brackets. Plywood again, and where the job forces a fixing into fibreboard, get it into the face rather than the edge. Edge fixings in MDF are the classic slow failure: nothing wrong on handover, a dropped door at eighteen months.

Flat visible faces. Laminated MDF. Nothing applied on site matches factory laminate for evenness across a run of doors sitting next to each other, and the Alnoor Lasani ranges arrive finished on both faces, which also takes a variable out of the warping question.

Profiled or moulded work. Plain MDF, then finished. This is the one job plywood does badly, because routing exposes the ply lines. Worth pricing separately since it changes both the material and the finishing sequence.

Comparing a cheaper quote

When a customer brings you a cheaper number, it is almost always grade, glue type, measured thickness, core quality or sheet size rather than a better deal. What actually drives board prices takes each of those apart. The one worth checking on delivery is measured thickness: a sheet sold as 18mm that measures under throws out every hinge and runner calculation on the job.

Edge treatment is the specification, not a finishing detail

Almost every fibreboard failure starts at an edge. Not a face — an edge.

Band every cut edge, including the ones facing the wall and the underside of a base unit where nobody looks. The back edge of a sink cabinet is where swelling starts, precisely because it is the edge that gets skipped.

If you are quoting against somebody who has not priced full banding, you will look more expensive and you will be right. It is worth naming on the quote so the customer can see what the difference actually buys.

Hardware compatibility, before the carcass is cut

The sequencing error that costs money is cutting carcasses and then choosing hardware.

Pull-outs, baskets, corner mechanisms and waste units are made for specific cabinet widths. Corner solutions in particular cannot be retrofitted in any sensible way once the box exists. Decide which cabinets get drawers, where the bin goes, whether the tall unit is shelved or a pull-out, and what the corner is doing — then cut.

The Wellmax range we carry lists the sizing for each item, and the accessories guide covers what fits what.

Moisture, realistically

Not every cabinet needs the same treatment, and specifying BWR throughout is over-building the dry two-thirds of a kitchen.

Sink cabinet, anything in a utility run, anything against a cold external wall: BWR, banded properly, and consider PVC shutters rather than laminate where it is genuinely wet. The rest of the run does not need it. The shutter comparison covers where PVC earns its place.

What we hold

A-Grade plywood, 3mm to 25mm. The full Alnoor Lasani LMDF collection across nine ranges, as an authorized dealer. MDF, door skin, imported timber and Chawla PVC through Janjua Timber Merchant and Aziz Wood House, the two family shops beside us — which is usually one trip rather than three. Wellmax hardware for the moving parts.

Bring a cutting list and we will work out sheet counts against it and quote the day's rates. Estimates are free, and returns are accepted under our return policy, which matters when over-ordering by a sheet is normal on a kitchen.

Good to know

Questions we get asked

Which board holds a hinge screw best?

Plywood, because the screw threads bite into timber fibre running crossways. A screw into an MDF or LMDF edge is biting into compressed fibre, and under the cyclical load of a door opening daily that seat gradually loosens. Where fibreboard has to take a fixing, the fixing wants to be into the face rather than the edge.

Can I order to a cut list rather than by the sheet?

Bring the cut list and we will work out the sheet count with you at the counter, including the offcut you will want to keep for adjustments. Order by the sheet and you carry the yield risk yourself, which on a job with several different thicknesses is where quantities usually go wrong.

Can I rout a profile into LMDF?

No — routing through the laminate exposes the core, so profiled edges are a plain MDF job that then gets finished. If a design calls for moulded door edges, that is one of the few places plain MDF is the right specification rather than a compromise.

Do you supply cut to size?

Tell us what the job needs when you bring the cutting list and we will tell you what we can do on it. Estimates are free and we quote against the day's board rates.
