An honest manufacturer I sell and install garage doors and we use the manufacturer C.H.I. I believe they are actually honest in their R value publications, their brochures and their specifications sheets use the terminology DASMA TDS #163. I have been hurt as a business several times going up against the manufacturers you've mentioned in this article, because of their inflated values. How do people believe a garage door that's 1 1/2" thick is providing them an R value of 17? I'm sure because it's in writing right on the brochure! I do believe CHI is representing themselves accurately, but it appears to be at a cost. Please see their website at chiohd.com I think you will add them to your list of manufacturers that are trying to play by the real world rules even if it is at a cost.
