Since locating our new central heating boiler into the loft I find
need to convert from cold loft to warm loft to limit excessive ga bills in the winter from the frost thermostat being constantly on.
The question is - what would be the best way to achieve this?
The house is a 1950's semi with no sarking under the tiles (tile visible from inside loft). Present insulation is 200mm glass fibre o loft floor.
Most loft insulation manufacturer websites I have visited assum sarking is present.
Thanks in advance for any advice
