Four bags will cover one cubic meter e.g. 2.5m x 2.5m x 150mm thick. So, to give an example: installing it 150mm thick in an average size loft of 45m squared would require 27 bags:- 45m2 x 150mm x 4 (4 bags is one cubic metre) = 27 bags. At £10.50 per bag this gives a total cost of £283.50. Typical savings on your heating bill would be approximately £50/£60 per year with annual savings of CO2 emission of 750 to 900 kg.

Supplied in 8kg bags with a minimum initial order of 15 bags (£157.50), with a free hatch pack with every order. Extra bags can be purchased but there will be an extra charge for delivery. Please place your order with contact details and we will get back to you with this extra cost.
