Posted By: fostertomDo you mean 300 underfloor insulation, or the 300 in the cavity? The former would defeat the purpose of the latter, if you did both.
Posted By: fostertomThat is a deeply impressive presentation - all said together in one place, comprehensive....Surprised you weren't already aware of it Tom, also check out Energiesprong. Seems like the right way to do retrofit at scale for identikit houses (social housing etc). Shame my house isn't identikit!

Hi Tom - I think if you tried sketching freehand the isotherms and heat flux lines you would soon see that the flux lines must diverge [...] A picture would help but...............
Posted By: mike7the flux lines must diverge as they leave the bottom of the insulation barrierYeah but they also converge as they approach it - it's symmetrical so doesn't matter that happens to the flux lines in between. Cant quite picture 'ratio of adjacent sides of each curvy square of your grid must keep constant' but feels like that'll be symmetrical too.
