Retrofit Kingspan to pitched ceilings

Anonymous user 15/03/2024 - 2.45 PM

We’ve moved into a dorma bungalow with 2 bedrooms and a small bathroom upstairs - built this way in the 80’s, not converted. The whole house is ridiculously cold unless we have the heating on constantly. Precious owners installed a very good boiler 3 years ago and we’ve had it serviced and improved the radiators per room size. Problem is the speed at which the house loses heat. The hallway and upstairs rooms drop to 12 degrees over night if we don’t leave the heating thermostat on. Considering a thermal imaging scan and report but we assume it will say there’s a lot of heat loss from the pitched ceilings. The staircase has a full length pitched ceiling and the bedrooms each have 4 areas of pitched ceilings. We’ve had some of the government funded insulation companies come round for an assessment (my elderly mother lives with us so we qualify) but they’ve found that the loft insulation is ok and that there is some cavity wall insulation (another question - can we get that topped up privately as downstairs is also super cold). One company suggested that we retrofit Kinspan on all of the pitches ceilings and skim over. Any advice out there if it’s worth it and the process? Do we plaster board over it before skimming? What thickness of kinspan is recommended? Finally, our road is slightly inclined, so there is a gap under one side of the house. The downstairs bedroom and bathroom on that side have very cold floors despite thick carpet/underlay. What are cost effective options to help with this? Any advice would be greatly appreciated. Google rings up so many different opinions / options
