Thanks to Peter Warm and his THERM settings and libraries, I now have my first working model which appears to be correct and putting our sensible results.
I am now in the PSI from THERM pw30 excel spreadsheet and have successfully copied out external and internal U-factors into S and T 16 which have transferred to the appropriate boxes. What do I put into U 16 to give me L2D ?
I am hoping that once L2D is in place the rest of the sheet will self fill but would be interested to know whats next if this is not the case.
Any help or advice would be appreciated.

Hi Peter
Well my first advice would be to do Pete’s Therm course if you haven't done already….But, what kind for junction you are looking at? It would also be useful to have a screen shot of your excel sheet completed so far and maybe the detail your are assessing?

Hi Ruairi
I intend to do the course at some stage but the next one is not until May. I am looking at a 90 degree corner in a timber frame wall.
I attach a screenshot from excel which has a drawing in it and the report from Therm. I have had a go at a mathematical calculation which brought out a psi of 0.00818 which I suspect is quite wrong so if a can work through the speradsheet I would be more confident in the result.

Excellent, seems to make sense, thanks Ruairi.
I will give that a go. - 19 December 2011 at 9:37 pm #38316
great manual Ruari!!
I'd echo your point about doing the course. I had been using Therm for a few years but still learnt a lot on the course.
Pete's sheet is great but it's good to do the long hand calculation (as Ruari has outlined) as well so you can get a feel for what psi values are about.
