James Fincher is a builder in Oklahoma who’s leaning toward designs with conditioned attics insulated with spray polyurethane foam.
However, he’s not convinced that a conditioned attic is the best approach in a large home — something, say, in the 4,000 sq. ft. to 5,000 sq. ft. range.
The problem, as he puts it in his Q&A post, is the “sheer volume” of attics in a house this large, and whether the increase in volume will force him to use a bigger HVAC(Heating, ventilation, and air conditioning). Collectively, the mechanical systems that heat, ventilate, and cool a building. system.
