I insulated our crawlspace today.
No big deal.
Just got one of these HUGE insulation boards.
Had my boys a Lowes cut it into thirds so I could fit it in my car.
Measured the crawlspace vents.
Used my box cutter to cut out my measurements on my insulation board.
Shoved the insulation in my perfectly measured crawlspace vent.
According to this picture, it is VERY important.
