Insulation supply formats.
Choose the actual material and supply form. Each sheet identifies what to measure, which product data to collect and a purchase assumption to check.
Insulation batts
Measure each supplied bay's clear width and length rather than the outer frame area.
Prepare this material →Rigid insulation boards
List the complete board blanks required by each supplied layer plan.
Prepare this material →Separate insulation layer packs
Measure each layer independently, including its own openings and coverage.
Prepare this material →Loose-fill insulation
Measure the supplied internal cavity volume after deducting obstructions.
Prepare this material →Insulation wrap blankets
Measure supplied wrapping paths or complete cylindrical blank dimensions.
Prepare this material →Preformed pipe insulation
Measure existing pipe run lengths and the selected insulation's inner and outer diameters.
Prepare this material →How these quantities differ
| Material | Selected product data | Ordering mistake to avoid |
|---|---|---|
| Insulation batts | Batt dimensions, pieces per pack and any explicitly permitted orientation. | A total area allowance does not prove that complete batt pieces fit each bay. |
| Rigid insulation boards | Usable board dimensions, pack quantity and cutting gap. | One total square-area order may omit stock lost to blank fit. |
| Separate insulation layer packs | Selected product thickness, pack area and density where mass is needed. | Different layer products cannot be pooled into one pack count. |
| Loose-fill insulation | Specified installed density and mass per bag. | The density of loosely packed material in a bag is not necessarily installed density. |
| Insulation wrap blankets | Roll width, usable roll length, supplied lap or helix pitch. | A roll's gross area may cover fewer complete pipe wraps than area division suggests. |
| Preformed pipe insulation | Usable piece length, pieces per package and actual annular dimensions. | Outside pipe diameter alone does not describe insulation material volume. |
