Chipboard grades and where to buy square-edge flooring grade for delivery

Dec 09, 2014 5 Replies

I do have a question, below, about where to buy board suitable for flooring but before I get to that I thought some folks might be interested in info I found out about grades of chipboard. (Strictly, I think these may be grades of particleboard - perhaps leading to the "P" in the grade name. Maybe someone can confirm whether that's right or not.)



Chipboard grades



P1 - "General purpose" P2 - Boards for making cabinets, not load-bearing P3 - Moisture resistant, not load-bearing P4 - Load bearing for dry conditions P5 - Load bearing, moisture resistant P6 - Heavy duty load bearing for dry conditions P7 - Heavy duty load bearing, moisture resistant

From some specs it seems that the differences between the normal and heavy duty load-bearing grades (e.g. between P4 and P6) is not the thickness (such as 18mm or 22mm) but the rating of how far apart the joist centres can be:



P4 and P5: 450mm P6 and P7: 600mm



Others say that 18mm is for 450mm joist spacing and 22mm for 610mm spacing.



Sizes



It seems that it's not possible to buy flooring-grade chipboard in 8x4 sheets. At least, I couldn't find any. Instead, square-edged P4-P7 seem to come in 3050 x 1220mm sizes.

Anyway, that's just background. Can anyone tell me a good source of chipboard with the following spec


  • flooring-grade P4 and P5 (I need some of both)
  • 18mm thick
  • square edged, i.e. not tongued and grooved
  • with a UK delivery service (to Aberdeen, in this case)

The board sizes are not that important as long as they can be delivered. Within the spec, lowest cost would be best.



I also need some plasterboard sheets as follows


  • some for moist environments (a bathroom)
  • some with thermal insulation properties
  • some regular

so if one supplier will deliver both chipboard and plasterboard that would be a bonus.



Anyone know of a good supplier of such materials? I am not trade registered so it would have to be a retailer.

Cutting a very log story short, I don't think you will find square edge boards meeting your specification as it is not possible to meet those specs without tongue supported edges.

If you (understandably) wish to use square edge boards then you will need to use thicker ones and/or additional edge support.

I have just laid a deck of 18mm square edge USB3 for roofing (as I could not get T&G in time) and I had to use additional plates of usb underneath (in place of noggins) to get the rigidity that the deck required.

It took an age for me to drive the screws required for those extra plates so I would suggest you consider going T&G for your application and cut the tongues if you need access in the future (with attendant reinforcement as required).

On the trade supplier requirement, if you are buying enough then you don't need it. You simply call (or email) for a quote against a supply list and argue the toss if you don't get the price you want. First call is to the supplier you least likely want to deal with (say travis perkins), practice your script and ask for a quote (for James Harris Trading). Work up to your favoured supplier and you will have ironed out your previous inevitable mistakes in the script. My local small outfit has 'cash1' for walk ups and 'cash2' for at approx 30% discount for those that have a bit of volume (say 200quid) and make an effort. Haggles are dealt with on the basis of, "Your price for OSB3 is fine but TP will do 12mm PB at 10% less, will you do a price match?".

Actually, around Cambridge, phoning up and asking for a price before you walk in the door will get you a 20% discount. (No haggling, trivial amount).

Thanks. That turned out to be accurate: I could not find flooring-grade (P4 or above) 8x4 sheets and had to for T&G, much of which I'll have to rip the edges off.

I have a bathroom to floor (which will be T&G) but apart from that all the rest is for areas above new pipework or to replace sections of old flooring so needs to be square-edged. I want to leave the areas above central heating and gas pipes so that the boards can be taken up later - hence the square edge rather than T&G for much of the job. Although this is for square-edge sections the boards will be well supported including all the edges.

As you mentioned, I had to opt for T&G boards. Having got a shopping list ready on the Wickes web site their server kept experiencing an error when asked to go to the checkout section. I eventually phoned the order in but, unfortunately, they then said that Aberdeen does not qualify for free delivery and the cost to deliver would be ?80. That was a little on the high side!

Understood. I personally hate both haggling and the companies who vary their prices according to what they think they can get away with. I once had a salesman in a local store which I won't name try to charge me ?75 for something I eventually got him to come down to ?25 on. That's ridiculous and exploitative. Some people pay such figures and the companies get away with it.

In the end I got the products I needed from B&Q. Even for small bulk orders (5 or more) their prices dropped markedly. From their web site I didn't think they stocked what I wanted but to my surprise they had a bigger range in store. As the order was over ?300 delivery was free and should arrive today. I have to say that the staff in the Garthdee warehouse were especially helpful. So as long as the order arrives in good condition, this time it's thumbs up for B&Q.

Snip tale.

B&Q?

You bother to think & write & ask about good suppliers for your many & varied list of gear, get replies telling you what to do, then go to B&Q? Now you are gushing with praise even tho you haven't received anything yet?

Do I smell a rat here?

I rung around for prices on some plasterboard recently. Wickes were as cheap as the best price from a local BM's (list prices, with whatever discount it is for bulk orders).

I hadn't planned on buying it from them particularly, but was buying some other stuff (flooring mostly), and this also meant I could get it all delivered free.

Another advantage was that whilst a BM delivery driver would have plonked it on the drive, it came in a van with two chaps from the local store and they unloaded and carried it into my house and put it where I wanted. Good service and I'd use them again.

And their ply was better than the similarly price stuff from a local timber merchants
