Roof Operations and Spray Foam Insulation

First and Foremost we here at County Fire Tactics, FULLY support vertical ventilation and letting the HEAT OUT!  Heat rises and when you open the roof, you are releasing BTUs therefore lowering the amount of GPSs required for knockdown. It amazes me how many fire departments do not support or allow vertical ventilation. I wonder if the same individuals support having the flue open on the fire place?
