How many rolls of R-19 insulation are required to insulate the floor shown in Figure 15.15? The insulation comes in rolls 15 inches wide by 56 feet long.
What will be an ideal response?
Find the area of the floor as follows:
sf of floor = 24? × 36? + 10? × 13?4? – 8? × 4? = 965 sf
Effective coverage per roll = 16? × 56? / 12 in per ft = 75 sf
Rolls of insulation = 965 sf of floor / 75 sf of coverage per roll = 12.87 rolls – Use 13 rolls
