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 twin pack of Energy Saver in whichever thickness you need. This will give you the number of insulation twin-packs 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 3.04 m2 (the area of 100mm insulation in a twin pack) means you will need to order 24 packs of Energy Saver DIY Insulation
