Fit floorboards to a concrete conservatory floor

[Magic94]

About 3 months ago I had a Conservatory built it has French doors that step down onto a concrete floor I want to fit a floor with floorboards that raises the level about 4 inches. The concrete base has a damproof membrain. The concrete is not quite level, before the Conservatory was added the rainwater settled at one side. What is the best way to fit the wooden floor. I thought wooden beams screwed to the concrete and shims under the beams to level the any variations.

That's the answer.

Can you insulate between the wood too.

Yes I thought I would put insulation between the beams I was going to use 4 x 2 inches as the floor needs raising about 4 inches

Hi
It has been suggested I fit what is called a floating floor. Fit the beams round and across the floor leaving a 10mm gap to the wall which allows for any expansion and then complete as previous, Should the beams be fixed or allowed to float, which is best ??

The beams should be fixed.

What type of "wooden floor" are you having?

I had researched on the internet and found this - (Profloor Dynamic Batten provides excellent levels of impact and airborne sound insulation. The unique dual foam not only provides the performance characteristics but enables minor irregularities in the surface of the sub-floor to be taken up)they are then covered with 18mm / 22mm tongue and groove chipboard found this @ http://www.siginsulation.co.uk/Literature/Acoustic Brochure.pdf if you have time to look what do you think of it.

Thanks

1) I meant what type of floor are you having, not what sort of joists. As in floorboards, floating floor etc.

2) Who is living under your conservatory floor?

Ah.

18mm / 22mm tongue and groove chipboard

You said floorboards.

I thought you meant floorboards.

I assumed that too. The only time chipboard is classed as "wood" round here is when it goes into the "wood" skip at my local tip.

Rumour has it that chipboard used to be made out of wood, rather than past-use-by-date Weetabix.

I don't understand No.2.

It was the site advertising the joist's that states 18 / 22 mm chipboard. The floor will be covered by carpet so the finish is not important.
The floating floor suggestion is because of the changes in temperature and humidity causes the wood to expand and if the floor is fitted against the wall the boards buckle but I could fit ordinary floorboards.
As I understand it engineered boards are best but they are expensive

Oh good grief. I think everyone here, myself included, assumed to wanted an exposed wooden floor. There's no point in fitting engineered wooden flooring, or floorboards, if youre just going to cover it all with carpet. Use 18mm flooring grade chipboard.

Those expensive (I'm sure) composite joists are designed to reduce noise transmission through the floor to the room below.

Unless you have somebody living under the floor of your conservatory they are a waste of money.
