I have a bedroom extension above my garage (built before I purchased house) which always feels cold. I have insulated the loft space well above it but can feel the cold in the carpet which leads me to want to insulate the garage ceiling - I have a decent roller door so drafts minimal into garage.
Been reading threads on here and think that celotex or similar is best bet on garage ceiling. But looking at plastboard options like http://www.planetinsulation.co.uk/ZPL4025.php but wondered if I can then tape between the boards and then expanding foam around the edges or if it would be better to do without plasterboard so can tape joints better? Advice much appreciated!
Also would like some advice as to which of these or an alternative is better?
