For a fairly accurate calculation of your loft floor area you will need to measure two adjacent sides of your house, say the front and the side, and multiply these two measurements together. This will give you a close approximation of your loft area.

Then divide the loft area by the area in a pack of Energy Saver in whichever thickness you need. This will give you the number of insulation rolls you need to order.

As an example, if the front of your house is 8m wide and the side of your house is 9m long, then you will need 9m x 8m = 72 m2 of insulation. If you want to install 100mm thickness of Energy Saver then 72 m2 divided by 1.52 m2 (the area of a 100mm insulation roll) means you will need to order 48 rolls of Energy Saver DIY Insulation

The dwelling dimensions are provided as simple approximations – it’s always best to calculate the number of rolls for your own specific needs.
