Insulation and your new Shed?

Posted on : June 13, 2011

Like everything in the shed industry, insulation is another area full of jargon.  When you break it all down it is not too complex, the only thing you need to make sure is that you are being sold insulation for your shed that is adequate for your area and you are happy to take on the increase in your shed price.

If this is too much for you to digest with your morning coffee, then all you need to focus on is the R value.  Effectively the higher R value the more thermal resistance (keeps heat in or out) that your insulation offers.  This is important if you are considering adding an air-conditioner or heating to your shed or garage.  The BCA (Building Code of Australia) has worked out the requirements based on your location and altitude for both the roof and wall.

The R values of the same roof or wall vary between summer and winter – depending on which way the heat is travelling.  It is best to achieve minimum R value in both seasons for the walls and roof.

Follow these steps to work out your minimum R value and how to select an appropriate insulation.

Step 1 : Use the BCA zone classification to work out your zone

 

Step 2 : Work out the minimum R value for your roof and wall based on BCA minimum R values.
