Garage to home cinama conversion

[john59]

My aim is to erect a concrete sectional garage and convert it into a dedicated home cinema. The problem I will have is the floor regarding cold and damp how would you prevent any damp penetrating through the timber supports for the new floor that will be laid on top. Soundproofing is also a problem I will encounter, any suggestions peeps. And the roof will have to be replaced because the one that was on it was corrugated asbestos. Answers on a postcard please, or on here if you want Regards.

try avtalk and avforum sites

you can spend many happy hours on them getting all the info you need about constructing a home cinema

be careful - it could cost two arms and two legs if you go silly

Ta for the reply swelec, I am a regular on the sites you mentioned but the info I need is not there so asking on here seems a better option.
Regarding the floor, a visqueen sheet on the concrete should stop any damp from coming through to the wooden floor supports, correct?? and polystyrene infill should prevent cold from coming through aswell, correct??.
For the studing on the walls how should I fix the timber to the concrete ready for the insulation and plasterboard? is it simply a case of drilling through the wood and into the concrete then fix by screwing into a rawl plug?

Thanks in advance.
Regards.
John.

Not a good idea because the rain outside will penetrated to the fixing then into the timber studs creating damp problem. There are many ways of doing it and the way I would do it is to put down a dpm with a rigid insulation board, there are many difference type, here one of them then T&G chipboard flooring glued together acting as a floating floor. Leave a approximately 50mm gap all round the room and build a stud work frame like a caged 50mm away from the wall so no timber is touching the outer wall as it will now have a cavity wall and will a need air-vents on the outside for ventilation in the cavity area. You may need to hide some wiring in the cavity area before fixing plasterboards but first check with the electrician's on here for what is allow. Also make sure the outer wall is seal on the bottom to prevent the rain creeping in.

The same principles apply as building a music studio conversion, your best resources are:
