room calculator

this calculator has a great rep around the www. I find it super useful, and love the way it graphically depicts the hot/cold spots in a given set of dimensions.

It seems that everyone here has to deal with this eventually -- what are your tricks to tame small rectangular room problems?



I find smatterings of details for room treatments involving Owens Corning 703, but very few details on actual implementations.



What are people doing for a low cost solution? Are you hiring consultants to measure your rooms?
