Enter your ceiling area in m²:

Pack coverage varies by width:

• 430mm batts: 10.47 m² per pack
• 580mm batts: 11.6 m² per pack

Insulation batts come in different widths to suit the spacing between the timber or steel joists in your ceiling or wall.

430mm wide batts are designed for 450mm joist spacing (common in older homes and wall cavities)
580mm wide batts are made for 600mm joist spacing (common in modern ceilings and newer builds)

Not sure what spacing you have?

You can measure the distance from the centre of one ceiling joist to the next. If it’s close to 450mm, choose 430mm batts. If it’s closer to 600mm, go with 580mm batts.

Choosing the right width ensures a snug fit with no gaps or compression — which means better insulation performance.
