Over the past couple of weeks we've had had lots of advice on the wall and roof sections both structurally and thermally.  We've started to put together some options for further discussion and some costing.

This plan gives us close to R50 walls, R90 roof, and an R30 break between the 1st floor and the basement.  ( This basement situation is still to be worked out on many levels)

I think we have clarified that the interior stud wall on the new 3rd floor that is non load bearing can be wood.

We're also kicking around the idea of a recycled epdm membrane instead of the Tyvec layer on the roof – could be interesting.

I have not detailed the front and rear walls – but I believe we will build them out of wood – not steel stud, but otherwise be a similar section.

Some final notes - I have a line on some used XPS – enough to do the 6” on the roof and 6” in the basement.  The tenant has agreed to move out on June 6th – so we will have a project schedule out soon.

Section options are as follows:
