Home Cinema room too COLD

[freyster]

[FONT=Arial]Hi All,

I've recently gutted my back room where the old cinema room use to be as it was constantly cold; due to having 3 external walls with no insulation.

As I've taken the wall back to the old plaster, I wanted some advise on how to insulate the room as its an old Victorian semi detached house so no cavity walls, just solid walls. (currently the room still has the old plaster on the wall)

I was considering building a timber frame work and insulating it with rock wool or celotex about 50mm and then installing 15-20mm Thermal plaster boards.

Will this be sufficient to keep the cold out and room warm as it was unbearable . Also should I go for rock wool or celotex. I will be loosing space in the room but I would rather keep the room warmer then cold.

Any help, guidance, advise will be much appreciated as this is all new to me.

Thanks

Hi,

If the room was unbearably cold, then a stud work frame with insulation in and plasterboard finish may be better for you as then you can fix insulation within the voids.

Rockwool and celotex are both options, celotex will cost more but is a higher performance board so will take up less room than rockwool for the same amount of insulation benefit.

Hi

Thanks for getting back to me and advising me to go for the celotex.

Do you recommend a 50mm board of celotex as it ranges from 10 to 120, i thought in the middle range should be sufficient esp as having thermal boards put in.

Also where the joints will be in the celotex board should I tape this with the heat tape or duck tape so that no air gap is present. Also tape the celotex board to the timber frame.

Thanks

if you are framing it out then use metal as the insulation can be tucked in tot the stud making it continuous.

What sort of metal frame would I use and where would I buy this from.

Also once the metal frame is up, how would I fix the thermal plaster boards on top?

Thanks

metal studding from most builders merchants. slot insulation in the screw you insulated plasterboard over the top.

or

use marmox panel on the walls and then PVA and skim them

What's the ceiling like - is the heat disappearing up there too?
