How To Estimate The Number of Bags Required:
- Measure the floor area of your rooms to be insulated, then subtract 10% of the area to allow for framing. (if you have an angled or raked ceiling it gets a little more complicated, go back to your high school trigonometry!)
- Measure the average spacing of framing timbers. This is usually around 450 or 600mm. If you have 450mm spaced framing, choose the 430mm wide batts, if you have 600mm choose the 580mm wide batts.
- Divide the area required by the area per pack. Round up to the nearest number of bags.
- You don't have to be exact with the estimates, there's always extra bits of framing to avoid or other gaps to fill in. Within a square metre or two is fine.
- Because polyester insulation is safe and non-toxic, leftover insulation can be used to make cushions, pet beds and kids costumes, restuff kids toys, make acoustic control panels, let your imagination run free.
Practical Example on Choosing the Autex Greenstuf Insulation Batts
E.g. We have a 4m x 4m room with a flat ceiling. The framing is spaced at 450mm centres and we'd like to install R3.5 batts.
In this case, we're insulating all the walls with the same type. In a normal house, you'd usually insulate just the exterior walls and consider using sound insulation for the internal walls, depending on room uses.
- We have an area of 4m x 4m = 16m2.
- Subtract 10% for framing = 16m2 x 0.9 = 14.4m2
- Looking up the table, a bag of R3.5 batts @430mm will cover 3m2. So we'll need 14.4 / 3 = 4.8 bags, which we round up to 5.
- Order 5 bags, insulate away and enjoy the increased comfort!
