Over the past few days Darren mainly, but also with a little help from me, has worked on the outside of the staircase.
It has a breeze block interior, but then various layers have to be built up on the outside.
Firstly a 100 mm wide timber frame that is filled with 100 mm wide solid insulation.
On top of that goes large sheets of 60 mm wide insulation.
Then on top of that, as you can see in the same picture is a breathable membrane that comes in a big roll.
After that timber battens are screwed through on to the timber frame to make a seven metre tall sandwich.
That's all that we can do for the time being, but as I said a week ago, the scaffolding is coming down next week. Unfortunately I was wrong then, but hopefully it will actually be removed next Monday or Tuesday.
If it doesn't go soon I will lose my patience and start taking it down myself.
The final bit of the sandwich is a topping, so probably I should describe it more like a pizza instead of a sandwich.
Anyway, we are still keen to go with timber, and after receiving a giant quote a week ago, I have managed to get for about half the price, so we may be back on track.
