Nanawall or La Cantina Folding doors and blower door performance?
I am curious if anyone has experience with blower door performance on a Nanawall or La Cantina folding door system (not as isolated elements, but rather impact, whether good or bad, on whole house blower door performance). I am a builder in Seattle area getting ready to start a new construction project with a number of great energy features including SIP wall and roof assemblies. This house has good potential for a relatively tight building envelope, but a folding door (14′ wide x 7′ high) has been added late in the game and I have some questions/concerncs how these doors perform with regards to infiltration.
