Using insulation in metal roofing is nothing new. It has been a popular roofing choice for a long time. Colorbond roofing is also a great decision, because it’s more durable, lasts longer, and is a better investment from a financial standpoint, especially if you take good care of your roof.
Although some installers sell metal roofing as a great insulator on its own, it really isn’t. Properly installed metal roofing insulation is a must. 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 installed without insulation, you will lose a lot of your home heat or cooling 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 drive up your electricity 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:
- Lower your electricity bills
- Shrink your 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.
Spray foam insulation applied directly to the spots that are most problematic is a popular option. Foam batting expands as it’s applied, forming a tight thermal seal that keeps outside air from getting 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).
- Batts – Some are manufactured in Australia using renewable raw materials for improved sustainability, and many are specifically sized to fit 99% of Australian ceiling joist spacing for easy installation.
- Fibreglass insulation – (some contractors advise against it, worried that condensation may damage the batts. However, placing a protective plastic sheet over the fibreglass batts as a vapour barrier solves this issue);
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). Look for insulation materials with the highest thermal resistance; they’ll perform better in hotter conditions.
Once your home is properly insulated, you’ll notice a difference in temperature regulation almost immediately.
