reet then cockends.

 

im about to start converting my garage which currently has a concrete floor 130mm below the kitchen floor.

 

i was to use kingspan Thermafloor k3 sheets so a separate vapour control layer wouldnt be required, but the thickest i can find is 70mm.

 

anybody have any experience in such an area, if so, what do i do?

 

ta muchly

also 6" joists will take me over my 130mm limit.

 

will 4" still do the job?

 

Spanner in works again....according to

 

http://www.planningportal.gov.uk/england/g...5315233135.html

 

should be min 150mm between top of slab and underside of timber. Assume reason being airflow.

 

So reckon 70 insulation & 60 sand/cement screed is the way to go. Light steel mesh for shrinkage cracking (A98)

 

So basically you should have listened to the woman right at the start

oh ffs...

 

right, back to airbricks, kingspan TF70 and and a shitload of screed.

 

at least its a much simple job now.

 

cheers

1m? isnt that much!

 

Anyway good luck. You'll save yerself loads not employing a builder to manage it.

 

But only you to blame when it goes wrong

do i need screed?

 

father in law reckons 100mm kingspan and then just board it out.

Aye. Costswise if it's OK do that.

 

100mm insulation, 18mm chipboard & carpet and you're about there.

and fuck the building regs off?

 

?400 bricks/bricky

?300 window fitted

?200 kingspan

?100 boards

?40 skirting

?400 plasterer

?150 flooring

?100 decorating

 

?1790 all in. (plus ?2250 to smiffs obviously)

 

next door cost just shy of ?9k

 

lovely!

Word of warning.

 

The floor will move if you just plonk floorboards down on top of 100mm kingspan.

 

What you going to fix the boards to? Screw into the kingspan? Dont be daft, it's glorified polystyrene.

 

You'll put weight on one half of the room and the floor will lift on the other like a see-saw.

 

 

If your worried about the airflow and all that goes with it, insulation and screed is the way to go but get someone in because you will fuck the screed up if you dont know what you're doing.

Should the kid not be in bed by the time the footie's on and if not watch it in the pub.

what about that rubber type flooring you get in kids play areas ,internal and external stuff.you can get different colours and it will save on carpet etc.www.abacuspg.co.uk ,www.sitr.com ,this type of stuff.

While we're on about building, I'm after putting a new roof on my garage (Because I'm keeping it as a garage) I'm after some box profile tin covered in plastic type stuff, any ideas, please.

Its cheap enough from most building merchants. CW Berry in Leyland are reasonable or Buildbase in Farnworth.

I thought you house building types could get round all your energy calculation stuff by bunging more insulation in the loft at the same time as you do a garage conversion or a conservatory

 

 

Round here they won't let you convert a garage unless you have 2 parking spaces other than the garage - and you're not allowed to pave over part of a garden to get another space.
