External wall insulation - Timber frame

Reed_Richards

My advice would be to wait out a winter before you contemplate any major work done on your house and find out which parts (if any) are prone to being cold and which parts stay warm and cosy.  This will give you some idea of where you need to concentrate your efforts.

Did you have a survey done before you bought the house or just rely on whatever your mortgage lenders did?  Those fake vents make me nervous. 

I had a RICS survey but that's it 

Also fair shout about winter. I thought about getting an IR thingymajig from banggood too

Another comment I would make is that, normally, in a timber frame house, the windows will be fixed into the timber frame as it is built and made weathertight first.   

Your windows sit right out in the brickwork, with hardly any external sills, whereas ours sit well recessed when viewed from outside.   Do you have very deep internal sills?

Our external walls are 300mm thick overall......a 100mm timber frame with Rockwool batts as insulation, inside that a vapour barrier and then foil backed plasterboard.  

On the outer side of the timber frame is plywood sheathing then the cavity, then the facing brick outer skin, which as said is not intended to be load bearing.

Your white outer cladding looks to be instead of the brickwork, and would not have any great insulation value.

Our house was built in 1988.

Hey 

I'm not aware of that? I do want to enerphit albeit assuming the cost is worth it, so that's something there

I didn't realise the cladding wouldn't be useful for insulation

The point I cannot get you to grasp is that all your functional insulation is on the inside of the cavity. The plastic cladding is not useful insulation and the single layer of brick is not great either but even if it were it wouldn't matter because cold air can get into the cavity.
