Hi CJ! Welcome to Permies. It's exciting to see somebody taking big, bold steps toward sustainability.
I poked around cruxhomes.com, and was curious about several things:
1. Is that all the pictures you've got? I wanted to see lots and lots more.
2. Are those asphalt shingles?
3. What's the oldest Cruxhome? How's it doing? Has anything leaked?
4. The zero overhang on the gable end makes me nervous. Has that given you any trouble? Wood siding rotting around the edges?
5. The FAQ says,
Is the lumber used in a CruxHome treated in any special way?
The method of construction for the curved trusses or I-beams is an assembly of composite / engineered wood that is bent into the designed shape. No high temperature or chemical treatments are used to create the curved shape.
No chemical treatments are used to put the curve in the beams... that are made of glue.
It seems like you'd get better outcomes by scaring off your chemical-sensitive customers as early in the process as you can. Gluelam beams are non-optional (right?), so advertising "no chemical treatments" is going to bring the wrong people into the sales pipeline. If somebody's not ok with glue, they're not the customer you're looking for. Dontcha think?
