What it's used for

  • Upper floor decking laid over timber joists in new-build and renovation projects
  • Loft conversions where a solid, load-bearing floor deck is required
  • Ground floor construction over joists where moisture during build is a concern
  • Mezzanine floors and timber frame construction requiring a structural walking surface

Fitting and handling

Store boards flat and off the ground, under cover, before installation to prevent moisture uptake from the slab or ground beneath. Apply PVA or flooring adhesive to the tongue and groove joint before tapping boards together, then fix through the face or secret-nail through the tongue at each joist, using ring-shank nails or screws at no more than 300mm centres. Leave a 10mm expansion gap around the perimeter of the room before laying any finished floor covering such as carpet, laminate, or vinyl.

FAQ

What is the difference between P5 and standard chipboard flooring?

P5 chipboard is manufactured with a moisture-resistant resin binder, making it significantly more tolerant of site moisture during construction than standard P4 or plain chipboard. It is less likely to swell at the edges if exposed to temporary dampness, though it is not waterproof and should not be left permanently wet.

Should I use 18mm or 22mm P5 chipboard for my floor?

For most domestic upper floors with joists at 450mm centres, 18mm is generally sufficient. Where joists are at 600mm centres, or where the floor will carry heavier loads such as in a loft conversion used as a habitable room, 22mm is the recommended choice for additional stiffness and load distribution.

Can P5 chipboard flooring be used in a loft conversion?

Yes. P5 tongue and groove chipboard is widely used in loft conversions across the UK as the structural floor deck. The interlocking T&G profile spreads loads across adjoining boards and reduces squeaking over time, making it well suited to habitable loft rooms. Always check that your joist sizing and spacing meet building regulations for the intended use.

Easy and quick to assemble, looks great!
My husband loves to collect different fragrances. I could have worse “problems” than him smelling good, I guess! But it has meant bottles galore. I grabbed this to bring some order to the chaos. It arrived in pieces with screws and a little screwdriver (it was so cute!) In all, it took me about ten minutes or less to assemble. It was super easy and the instructions were perfect. The pieces are labeled so there is no doubt you’re doing it right. When putting the spinner on the bottom, there is a hole you can rotate so you can attach the screws one at a time through the hole. It’s very sturdy once put together and holds all the heavy bottles with no issue. It truly does hold a ton! It looks way better than bottles all over the table. The black is very modern and clean looking. I did take photos of a spot where the faux leather was peeling up a bit from the edges, but I was able to use a credit card to smooth it down pretty well. This is a great organizer that look way more expensive than it is. He was super excited when he got home from a late meeting and I had put it together for him. He got right to work loading it up with bottles. And of course, it would be great for makeup or any other things of similar size you would want to organize. A great value to tidy up your space!

This product is not worth the price.
The screws were still very loose even after being tightened, and they couldn't be made to fit tightly. This resulted in the entire product being loose and unsteady. I spent 31 US dollars on this defective item. I'm very regretful. I will return it. The overall workmanship is not perfect. It's too bad!!!

Smooth Rotating Organizer – Looks Great & Holds a Lot
This was a hit in our house. I originally got it for myself, but my wife quickly pointed out that she has about 20 perfumes while I only have a few colognes… so it officially became hers. The assembly was very easy, with clear instructions that made putting it together quick and straightforward. Once assembled, it has a really nice black wood grain finish that looks clean and modern on a dresser or bathroom counter. The 360° swivel works smoothly, which makes it easy to access everything without having to move bottles around. It also holds a good amount, so it’s perfect for anyone with a growing collection.

Very nice little box.
This is a great little jewelry box. I don’t have tons of jewelry right now, so this fits everything well, and the leather-look material is very nice. I like the simple design and organization, and it is a nice size to travel with. It looks really pretty sitting on my dresser and goes with the aesthetic of my home well.
