Porthole Posted February 21, 2022 Share Posted February 21, 2022 Hi there Be grateful for your comments. We have an integral garage and the builders have built a stud frame on the external wall to hide some pipes but the stud is coming off the wall quite a bit, so you lose roughly 150mm of the room, maybe because he is trying to square up the room. The garage is fairly narrow to start with so this does make the room a lot narrower. Can you please tell me if this is a necessary buildings regs requirement because we are converting a garage to habitable space? Bit disappointed about how much room we are losing. It was going to be a gym so didn't need to be too warm really. Many thanks Link to comment Share on other sites More sharing options...
Marvin Posted February 21, 2022 Share Posted February 21, 2022 (edited) Hi @Porthole If your garage wall is a party wall with another then this may be required for sound reasons. What's the other side of your garage wall? Is it a solid or cavity wall? More info please. Edited February 21, 2022 by Marvin Add info Link to comment Share on other sites More sharing options...
markc Posted February 21, 2022 Share Posted February 21, 2022 Nothing to say how thick or thin a wall needs to be, sound insulation can be achieved without big loss of space. im guessing it is more for ease than anything else, speak to the builder Link to comment Share on other sites More sharing options...
Polish Builder Posted February 21, 2022 Share Posted February 21, 2022 Hi @Porthole I used rock mineral wool non-combustible material with standard 45kg density in my extension to reduce the sound and get additional fire protection. Maybe that's the reason why they build stud frame to fit insulation slabs between the studs and then screw the plasterboards to skim it over. In my opinion RS45 or RWA45 will do the job there is no point using higher density insulation slabs (RW3 60kg or RW5 100kg density per m3) Fairly easy to find local supplier: https://insulationgo.co.uk/100mm-rs45-knauf-rock-mineral-wool-building-slab-45kg-density-acoustic-insulation-multi-application/ https://www.travisperkins.co.uk/cavity-and-internal-wall-insulation/rockwool-rwa45-semi-rigid-acoustic-insulation-slab-100mm-x-1200mm-x-600mm-2-88m2-pack/p/961938 https://www.ccfltd.co.uk/framed-wall-insulation/rockwool-rwa45-100mm-acoustic-insulation-slab-1200mm-x-600mm/p/961938 Link to comment Share on other sites More sharing options...
