Is insulation needed in metal roofing ?

Using Insulation in Metal roofing is actually nothing new – it has been a popular roofing decision for quite a long time. Colorbond Metal Roofing is also a great decision, because it’s more durable, lasts longer, and a better investment from a financial standpoint, especially if you take good care of your roof.

However, here’s the kick: though metal roofing is sometimes sold as a great insulator on its own, it really isn’t. Heat and cold can penetrate metal more easily than with other roofing materials, which is why homeowners need to look at options for insulation.

What Does Metal Roofing Insulation Do?

If your home is not insulated, you lose a lot of your home heat or cool through the roof. Your roof has some air space you need to take care of, and if you don’t it can be a real nightmare. To compensate for it, your home cooling or warming systems have to work in overdrive to make sure the atmosphere in your home is just the way you want it, which can translate into some rather high electrical bills.

The process of insulation is putting a barrier of material within your roof space, either between the joists, or rafters. This slows down the transfer of the air between your home and the outside world, protecting you against the elements. When insulation barriers do their job, you can:

  • Have lower electricity bills;
  • Less of a carbon footprint;
  • Increase your home’s value;
  • Prevent condensation

What Type Of Insulation Do You Need?

Regardless of the roofing material you have, you really need roofing or ceiling insulation. But, when it comes to metal roofing, you need to be careful as to what type you choose.

A popular option for this case is spray foam insulation applied directly to the spots that are most problematic. Foam batting, when applied, actually expands in size and creates a nice thermal insulation to ensure by making sure the outside air does not come in.

Other types of insulation that work great with metal roofing include:

  • Reflective foil insulation (perfect for warmer climates, and the reflective foils can be easily added to your home).
  • Bats- Some are maunfactured in Australia and made with renewable raw materials for improved sustainability. Many ceiling bats are specifically tailored to fit 99% of Australian ceiling joist spacing for ease of installation.
  • Fiberglass insulation (some contractors may advise against it because they are afraid the condensation may break it, but if you place a protective plastic sheet over the fiberglass batts to protect it against vapour barriers, you have nothing to worry about);

Most commonly, you’ll use insulation blankets of the material of your preference and add them to the space you prefer (unless you opt for the spray foam.) If you’re worried it might get too hot, look for insulation materials that offer the most thermal resistance – they will likely make it through even hotter temperatures.

Once your home is properly insulated, you can almost immediately notice a difference in the regulation of your home temperature.
