Insulation Calculator Functions and Data:

• Insulation Rolls for Walls in a Room - Computes the number of rolls of insulation needed between the studs in a room based on the dimensions of the room and the rolls of insulation.
• Insulation Rolls between Joists, Trusses or Rafters - Computes the number of rolls of insulation needed to cover an attic area between and over joist, rafters and trusses based on the dimensions of the area and the length and width of the rolls of insulation.
• Cellulose Insulation by Area and Depth - Computes the number of 25lb bags of cellulose needed to insulate an area at a specified depth.  It also computes the estimated R Value and estimated cost based on the price per bag of cellulose insulation.
• Cellulose Insulation by Area and R Value - Compute the Cellulose Insulation by Area and Depth calculator computes the number of 25 pound bags of cellulose insulation are needed to cover an area to achieve a specified R Value.  It also provides the depth of insulation needed and estimated cost based on the price per bag of cellulose insulation.
• Loose Fiberglass Insulation by Area and Depth - Computes the number of bags (27lb to 29lb) of fiberglass needed for an area at a specified depth of insulation.  It also estimates the R Value achieved and estimated cost based on the price per bag of cellulose insulation.
• Loose Fiberglass Insulation by Area and R Value - Computes the number of bags (27lb to 29lb) of fiberglass needed for an area based on desired R Value. It also computes the estimated depth of insulation needed to achieve R Value and estimated cost based on the price per bag of cellulose insulation.
• Shake and Rake Insulation Calculator - Computes the number of bags of loose (raked) insulation for an area at a specified depth. It also computes the estimated R Value.
