Attic Insulation
Works out how much more attic insulation you need, where air sealing first matters more than the depth you add..
Wall Insulation
Works out wall insulation, where the cavity depth is fixed and that limits what you can achieve..
Floor Insulation
Works out floor insulation, where keeping it in contact with the subfloor is the whole job..
Crawl Space
Works out crawl space insulation, where the decision to seal or vent comes before any R-value..
Basement Insulation
Works out basement insulation, where getting the moisture direction wrong is worse than no insulation..
Garage Insulation
Works out garage insulation, where which surfaces matter depends on whether you are heating it..
Insulation Thickness
Converts an R-value target into inches, which depends entirely on the material you choose..
Blown-In
Works out blown insulation, where coverage is per bag at a stated depth and settling is the thing to plan for..
Spray Foam
Works out spray foam, where open and closed cell are different products for different problems..
Batt Insulation
Works out batt insulation, where the installation quality decides whether you get what you paid for..
Rigid Foam
Works out rigid foam board, where the value is covering the framing rather than filling between it..
Cellulose
Works out cellulose, which fills irregular spaces well and has to be installed at the right density..
Fibreglass
Works out fibreglass, the most common insulation and the one most sensitive to how it is fitted..
Insulation Coverage
Works out how much area your material will cover, which is the number on the bag rather than a volume sum..
Insulation Quantity
Totals the material for a job, where the waste and the framing deduction are what estimates miss..
