Is there a verdict? pros and cons / effects
of unvented attic, sealed with Icynene spray foam
on HVAC system and ductwork?
[Plan is for 2-story construction, Central Texas
(read: outdoor temps around 100 F, humidity around 40%…) ]
Anybody with experience with such a setup
under these conditions?
How about considerations for “make up” air for HVAC system
