We have a slightly eccentric house, one that has been heavily extended so is a mix of old and new. On one corner, there's a small "tower" that we need to insulate. It's only a small room so I'm trying to avoid insulating from the inside ideally if possible. No cavity sadly. External insulation might work, but probably spendy as it's an odd shape. Any words of wisdom from the STW experts? My thoughts are just shove as much insulation in the roof space as we can and update the old double glazed window for now. North and East facing, elevated and is in the wind.
Is that tower an actual room or a fancy skylight for the room below?
Look ps to small to be a room in itself. If you aren’t wedded to it, I’d think about demolishing it and replacing with a lantern. Prob not what you want to do though…..
Ah re read , you said it is a room. I’d be putting external insulation and cladding it to match the rest of the second floor. It will be expensive. Another solution might be a really big heavy thermal curtain on the door where it joins the house and accept it’s going to be cold, b7t hopefully stop some of the heat drain?
Pic doesn't give much scale, it's roughly 2.5m sq internally. That side faces the street so we'd have to go through planning for external insulation I think. How spendy are we talking? 10K?

Multi foil is relatively quick , clean and easy to fit inside. With minimal loss of space.
Seal it off and store a madwoman in it.
updating a double-glazed window is almost certainly a loss in terms of CO2 and money.

That wont be helping, will it? Is it a bathroom? Try vent it somewhere else if its an extractor.
H.H.Holmes called and says he wants his hotel back. And also asked if you wanted to buy life insurance, then he asked me if I wanted to buy life insurance.
now he’s asking to to go to the basement with him. Back in a mo.
It's a bedroom and that is just a hole from outside to in. We're assuming it's had damp before so have just left it, but I am sorely tempted to fill it in.

She occupies the rest of the house I'm afraid 🙂
Will check out that foil @paton, cheers

I'd probably start there then!
I'd stick as much insulation above as you can and 25mm or 50mm kingspan on the interior walls. It won't be perfect but it will be a lot better than now and I imagine a lot cheaper than cladding the outside.
I love it. It calls for big double glazed windows in the outer facing walls and a large floor mounted telescope.
I should add that the vent is covered on the inside with a sliding plate (hit and miss cover?). I'm wary of condensation if we block it completely
If you go for internal insulation where will the dew point be in the wall? And what's the wall construction? Block with decorative elements outside or really timber and plaster of some sort?
Good point murray, it is either brick or stone (brick I suspect) all the way up and rendered. I think the dew point would potentially up being somewhere in the insulation, or between insulation and the inside of the wall. Could I work that out somehow?
