R-value wall calculator
All the best!
Ref. to “how to look at R-values” here is my private favorite:
In the free/private versions some limits apply – like that stuff like a Mooney wall ( frame members at 90°) can not be done. You fake that with all frame members parallel and accept the last differences/mistakes.. (Mooney wall, service cavity etc.)
Calculation is in 2D – have a look at the profiles across the wall/roof/slab.
Some of the results are R-value, condensation risk, etc. Better check yourself!
Canada is one possible location – then the climate zone can be used for a heat loss estimate of a whole structure etc. – really helpfull. Also then some input and some output numbers are imperial if chosen.
I would conside this as a step before doing beOpt.
Here below a screenshot of a typical 2×6 , 24 OC, with some external wood fiber insulation, ventilated cladding (a german fiber cement board in this case) – wall.
P.S. – this is not a promo. I trust that some might find it usefull. For me – I use that in an ongoing reno to judge condensation risks.
