Is insulation practical here?

Jim1000

hello guys,

I am doing up an old house which has an extension at the back built in the 80,s. This extension will be used as a kitchen now. 3 walls are exposed and the fourth side is internal. There is a little aeroboard in the cavity. The walls are sound and are in good shape.
Anyway I was going to put on 38mm insulated slab on this, but there will be a range in this kitchen against one wall and almost all available space left will be covered in kitchen units, right up to the ceiling. There will be a small space of wall between the countertop and the bottom of the overhead units which will not be covered.
I was thinking about fitting the units having to use longer screws etc.
Someone suggested to me as almost all the wall will be covered anyway, there is not such a need to insulate. And perhaps later if it proves to be an issue, I can always have the wall pumped.

Just wondering what you folks think of that.

Thanks a lot,

Rabbo

The units won't provide any additional insulation to the walls. I would get the walls pumped and look at installing additional insulation to attic

tks rabbo,

The ceiling above the kitchen will be well insulated. This will be a bedroom.

If you have the money, I'd pump the walls and stick up insulated slabs

OP, have you thought about pumping the cavity and externally insulating. This would be a far superior job than internally insulating and wont reduce your internal space. Plus not issues with fixing to the wall.

thanks lads,

I realize the units would not necessarily provide much insulation, but wouldn't they at least make some difference? It is a sizeable air gap after all. And if they are well stocked, which knowing my wire they will be, it is a big mass area.

The wall where the range is going is a flat wall with no chimney at the moment. I will be boring a hole in the wall and installing an external flue. How do I manage the insulation against this wall internally?

Cheers

Whatever about how you do it, OP, definitely insulate. We had a similar room, in this case a garage, with three exposed walls and a half-outside roof. We insulated underfloor (the only place in the house) in the ceiling and in the three exposed walls. The difference is staggering. From a freezing, almost unusable room it is now a comfortable bedroom.

Just for balance, if money was very tight I wouldn't bother just yet as you have the option to wait and see. If you've cash to spare do it. If its cold in the future you can still do it then by pumping or external. I'd concentrate on insulating your floors and ceilings and wait and see on the walls.

It really depends if its north or south facing windows?
