Internal insulation.

[Mark]

OK - its getting cold, and this year I want to do something about about it.

We have some walls of stone, some of solid brick. Some with Lime plaster some with the previous owners concrete on them.

What is thought the best way to insulate the walls internally?

I've read loads but find a lot of info confusing and not especially relable looking (seems common to give a figure for conductivity and call it resistance for example).

Im thinking insulation material against the wall, studwork and then either laths or clayboard or similar. What has worked for people without loosing too much space?

I read that current thinking is not to worry about insulation getting damp as long as it doesnt rot so not to worry about air gaps - but that seems strange as well?

Suggestions / thoughts welcome. Even daft comments.

A lime/hemp render applied direct to the walls to a depth of three inches is excellent.
You can buy the stuff ready-mixed from IJP/Lime Technology (just add water and trowel on), although I know that Nigel at Ty Mawr is working on his own version which should be slightly cheaper.

Please do conserve any original plaster though... all too easy to rip and strip and end up with nothing very historic...

Wassup? Lost your voice, or are you posting from the library? :wink:

Heavy hand-embroidered tapestries hung on the walls would help.

Well - I never thought I'd see the day when the mighty Goddess Nemesis cowered in a corner.

Not cowering, just bored.

Are horse brasses insulating?

tbh not much of the plaster in this house is worth preserving, every downstairs room has had the concrete fitted 3 feet high where they put the non-working injection dpc in. The only bits without are where I've redone the plaster.

I was leaning towards studwork/laths with insulation behind as being hopefully efficient and not taking up too much internal space and also not resulting in flat walls (I can plaster really badly without even trying)

My (lack of) plastering ability was very slightly involved in my house choice. There's no way I could produce smooth plastered walls, but I'm pretty certain I can do 'lumpy'. :wink:
