For decades, designers and builders of wood-framed homes didn’t spend much time thinking about insulation. The usual approach — still followed in much of the U.S. — was to fill the stud bays with fiberglass batts, and, once the ceiling drywall was installed, to unroll some fiberglass insulation in the attic.
Because of this decades-long legacy, it’s not unusual for a designer, builder, or homeowner to post the following question on Green Building Advisor: “We just finished framing, installing windows, and roofing. Now we have a few questions about the best way to insulate.”
My usual reaction is, “Really? You’re asking now?”
These decisions need to be made early
In many cases, these insulation questions are posted a few weeks too late. Why?
