Liner Calculations
QuoteSoft calculates liner from the inside of the duct item. Then scrap is applied. Below is an example of a 12x12 duct that is 1 foot long with 1 inch liner applied.
The liner panels that go inside the duct item will have to be cut to fit inside the duct and inside the liner itself. We’ll use this example to walk through the calculations.
2 sections of liner at 12in width and 12in length
12x12 = 144 square inches for one panel
144 x 2 = 288 total square inches
288 / 144 = 2 square feet
2 sections of liner at 10in width and 12in length
10x12 = 120 square inches for one panel
144 x 2 = 240 total square inches
288 / 144 = 1.667 square feet
Total square feet of liner = 3.667
After QuoteSoft calculates the total square feet, the scrap percentage is then applied.
