The following examples demonstrate the benefits of attic insulation:
Example 1 - No insulation in your attic - If your attic is not insulated and you lay 300mm (12 inches) of either Fibreglass Wool or Blown Rockwool you can reduce heat loss through your ceiling by up to 90%
Example 2 - 100mm Fibreglass wool in your attic - If your attic is already insulated with 100mm (4 inches) of fibreglass, topping it up with 200mm of Fibreglass Wool or Blown Rockwool will reduce heat loss through the ceiling by up to 60%.
Fibre Glass Wool versus Blown Rockwool - While fibreglass is marginally more effective, Blown Rockwool can be substantially cheaper. A "Complete Insulation Services", Representative will guide you through the benefits of both products and help you decide which is most effective for your situation.
