Unfinished basements have generally exposed basement ceiling. And if the roof of your basement does not have any insulation, it will be plagued by cold floors during the winter. That is not only uncomfortable, but it is also a real energy waster. Rectifying this problem does not take much time if you have the right materials and follow the correct plan.
Measure the length of the exposed basement ceiling between the first beams of the two roof on each side of the roof. Place on a mask filter and work gloves. Unroll your insulation and cut to the length measured with a knife. Place a ladder at one end of the roof. Push the end of the insulation length up between the roof beams, the paper side down and the edges of the paper into the staple beams. Place a staple every few inches on both sides.
Take your scale along the joist, raising the insulation and staple as you go, until you finish the first insulation strip. Repeat the process with each roof length between the beams until the roof is completely covered. With this insulation strip installed, start at one corner and install the standard-sized strip of insulation to complete the exposed basement ceiling.
