Thanks for the reply. Yes what is pictured is just the inside of the garage into the wall. Being a compete novice I may have been incorrect in calling it a cavity. If I was to rip the plasterboard back, what would you recommend insulating with to achieve the .28? The floor also is lower than the house so I have been looking at building a timber subfloor and insulating below? thanks

I want to begin looking at converting my garage and knocking into the kitchen to extend. I understand that walls between heated rooms do not necessarily require insulating although the wall to the outside will. I have used a hole saw into the plasterboard to try and find insulation although there is none. First question would be what sort of insulation would be required to pass building control? Since the walls have been sheeted and taped I was looking into the option of filling the cavity with poly beads. Any thoughts.

Like everyone in this section im new to the forum and look forward to gaining some guidnace and direction on a future self build. Having recently moved into a new home, i have decided to convert my integral garage and extend my kitchen. I dont even know where to start although i will begin posting some questions soon. Any help from you guys would be awesome!!
