• No. They're not insulated anywhere at all so the whole wall is a cold bridge. The windows will be the only insulated part. Got to love Victorian houses. The downstairs extension is ludicrously well insulated - you can almost feel the bulk of it when you're in there, it sort of deadens sound too. But the rest of the house leaks heat terribly.

  • Ah, fair enough. We're spending a fortune insulating as much of the original house as possible, but a big part of me has a sinking feeling we're pissing in the wind...

    I reckon your insulated suspended floor will make a massive difference, especially to airtightness.

  • Downstairs feels really different. Hard to explain, but it feels more still, and muffled. You can definitely sense the insulation under the floor. I think it should be much more comfortable. The thermostat is showing higher indoor temperatures but it's really hard to compare like for like with weather changing.
