How to insulant curved ceiling / how much insulation
Anonymous user 26 January 2021 - 11.26 AM
Sorry I've been struggling to fine and answer for this... The loft of my house is very low and the upstairs rooms all have curved ceilings where they meet the walls. My loft condensates really badly, I'm getting some tile and ridge vents installed to help with that. But especially in the winter the ceiling gets wet and really cold. I'm going to replace the insulation as it's wet, currently it's the old lose fluffy insulation. For these curves what and how much insulation should I be using for air flow ect.. Should o use kingspan between the timber or a roll of new insulation? As I'm conscious of the airflow with it being very small spot. I'm going to take down the curved plasterboard and reboard it so access will be okay Thanks in advance

Make sure the ventilation airways aren’t blocked with insulation, as this will will cause condensation as it can’t breath. If the problem on the curve continues after that , it needs replacing with foil backed plasterboard. Also ensure the insulation depth is a minimum of 270mm

Hi I have insulated a number of properties with curved (sloping) ceilings, and recommend you use “Easy fit rafter insulation” (Available for wickes) £11 a pack of 3. You need to slide these down between the joist to sloping ceilings. They are profiled so can snap off to fit! Access is via loft, not alway easy to access but a good Handiman should be able to deal with, if not able yourself? Also (or alternatively) you could insulate sloping ceilings / cold walls from inside bedrooms etc With a thermal insulation paper “ Wallrock kv600” thermal liner This you paste on with thermal liner paste. (Check on google). Very effective and less disruptive than taking down ceilings etc. Hope this helps Tony
