Air tightness and insulation coming soon

The long gap since the post about insulation below the damp proof course does not indicate a lack of activity - just my lack of interest in groundworks.

Once the groundworks are complete (and essential things like gas, electricity and water which for various reasons are being moved into the garage) we are on to the main external wall insulation and lots of air tightness work - hurray. June will be busy!

One thing to consider if embarking on a refurbishment project is that there are chickens and eggs all over the place, making life complicated and slowing things down.

For example, if the gas meter is on the external wall and you don't want to create a major thermal bridge by only insulating round it, you have to move it. But if you want to put it on the external house wall, that has to be insulated before re-instating the gas meter. So what to do in the meantime? Live without gas? Pay to disconnect and then reinstate, which costs more?

In our case, we decided to move the gas meter to the garage wall. Which would have been very simple if the garage had been in a fit state, but with the whole structure sinking badly, we decided to rebuild. Only now is the new garage wall in place to receive the gas meter. The rest of the garage can't be built until the external wall insulation is complete. So installation of the gas boiler and MVHR unit will have to wait until we have a garage roof. And so it goes on.
