I had my house re roofed last year and the roof leaked into a large utility room. I took the drop ceiling out and took down the ceiling panels above it and now I have to replace the insulation and put a ceiling back in. Its a very high celing unless I replace the drop ceiling panels here. Any suggestions? What kind of insulation should I use? I noticed some of the insulation has different numbers and some of it is very expensive so how do I know what to use?
go to lowe's or home depot, someone there will help you with ur problem at no cost. ps. ask for johns manville insulation, it is the best.
The numbers associated with it are called R Value. As a rule of thumb, the higher R Value numbers, the better. For example, fiberglass has about R 3 per inch (least expensive) and rigid foam has about an R 6 per inch (most expensive). If you have plenty of space to work with, you could do 10 inches of fiberglass (or a similar mineral fiber type insulation) and get the same results as if you used 5 inches of foam. It just depends on your situation. If you are in a very cold climate, I would suggest insulating to an R 49. If you are in a very hot climate, I would suggest insulating to an R 19 with a radiant barrier (more efficient than R 30 in warm, sunny climates). If you are in a moderate climate, you could be anywhere in the middle.
