RDH Research + Forensics
This company does research and "forensic" investigation on projects and then shares their findings. My favorite resource is the "R22+ Effective Walls in Residential Construction in B.C." because it describes many ways to get to California's 0.51 U-factor walls. In posting this review, I got caught up in 3 other reports they have shared, so easy to lose time at this website!
The following is the write up on their website:
