Here is a 60' x 120' Butler pre-engineered commerical buiding project we completed earlier this year for Hands-On Cleaning. The building is located in the Wausau Industrial Park and features 14" of fiberglass insulation in the roof and 6" of fiberglass insulation in the walls, (5) 12' x 14' overhead doors and a 4' high masonry wainscot. This buiding's roof also single slopes away from the overhead doors.
