Installing a timber floor

[CSG2306]

Hi all,

The end room in by bungalow 14' x 12' has a quarry tiled floor. It used to be the garage, but was converted into a bedroom many years ago.

I would like to raise the floor 8" to bring it up to the level of the other floors in the building.

First and foremost do I need permission, is there any regulations that I have to comply with, and most important of all "How do I do it"

My thoughts were to lay 1" insullation on the existing floor, and use 6" x 2" joists infilled with insulation with chipboard flooring on top.

I would be grateful if someone would tell me the correct way.

Thanking you in anticipation.

Regards

How about a "floating" floor CSG................lay 7 inches (approx 180mm) of rigid foam board (insulation)........Celotex and Kingspan are the most common...................cover with polythene as a vapour check layer.......lay 18mm tongued and grooved chipboard over............T&G joints MUST be glued with PVA........terrific level of floor insulation.........certainly no planning permission needed........ :o)

Hi The Builder,

I spoke with the suppliers of the insulation board that you suggested, unfortunately they informed me that it would not be suitable for laying a "floating floor".

The reason they gave was that the floor would eventually compress under normal wear and tear and become uneven.

Thank you for your suggestion, I was prepared to give it a go as it sounded great but!!!!!!!

I will have to return to plan "A"

OK then CSG................sod 'em LOL
Everyone's covering their a$$es so much these days..................these boards are routinely laid UNDER concrete floors, and concrete screeds..................if they feel like that, then put a floating floor over good old (cheap) polystyrene boards..I've done that many times................with NO problems...............

Hi csg, if you want THE info, contact the manufacturers they will have the answers. I tend to agree with The Builder, for this is a common form of construction in Scandinavia, also with concrete rafts and many constructions are decades old and still maintain their integrity
