How to calculate the "Required square footage" of insulation 


Once you select your "Thickness/R-value", the "Required square footage" box will appear. The Required square footage amount is derived by multiplying the number of rolls, times the width and length of the rolls. 


(Examples):

  • Ten (5 ft wide) rolls that are each 15 ft long. [10 x (5 x 15)] = 750 square feet.
  • Twenty (4 ft wide) roll that are each 100 ft long. [20 x (4 x 100)] = 8000 square feet.

To optimize the performance of fiberglass insulation, install Prodex Total between the fiberglass insulation and the metal sheeting. Prodex Total (insulation + radiant barrier + vapor barrier and condensation eliminator - All in one product), will keep your fiberglass insulation dry; thereby, allowing the fiberglass product to maintain its thermal value. Learn why fiberglass insulation loses R if it gets wet.

Because fiberglass loses R-value if moisture is introduced, we recommend you protect the fiberglass by installing Prodex Total between the fiberglass insulation and your metal sheeting. Prodex Total (Insulation + radiant barrier + vapor barrier and condensation eliminator all in one product), will keep your fiberglass insulation dry and thereby allow the fiberglass product to maintain its thermal value.  See comparing metal building insulation.
