Hi All,
Starting a new build and am so confused about insulation, probably the most important part of the build. Any advise welcomed.
The blocks I will be using is standard 4" solids and I guess the standard cavity is between 100 -110mm, my question is would much have to change in order to have a wider cavity lets say 120mm or 130mm? Would the extra width mean different foundations, more pressure on weight of roof etc. I was thinking of going with the pumped insulation in the walls, however I have no idea even after reading posts here of which type to go for? If I did decide to go with pumped insulation is there then a need to dryline the walls?
Also what kind of insulation do you need in the floors, the house is a bungalow, the guy doing my groundwork has not mentioned insulation is it standard to put insulation in the floor.
Roof insulation then is another question would you be better to use pumped or rolls of sheeps wool? I really am confused!!!
Hi Birroc, thanks for reply, using a 150mm does this mean I would not have to change my foundations as everything there is standard or would I have to tell the man whos doing my groundwork that I need the 150mm cavity as I am getting the site cleared today, breaking an entrance and stripping soil, Maybe its too late for this?

Also baldyman27, thanks for your response also, however I am not using underfloor heating, sticking with stove + back boiler + oil and solar panels.
I starting building 10 months ago. Built a 150mm cavity and filled it with beads. I have to say that the house feels toasty even though we're not in yet and there is no insulation in the attic yet. Only problem with the 150mm cavity was the 'cavity closers' at top but you can buy bigger ones. Not dry-lining. I like solid walls.
Can I ask Birroc if you used a standard concrete block for the inner leaf or a 'QuinnLite' type one and what width?
Hi Guys,
I was talking to my engineer, builder and they were saying to me that the bead type insulation can fill the cavity to much and not leave room for air flow thus causing water to seep through the blocks and other materials.
