Advantages of having roof insulation


Did you know up to 35% of a building’s heat loss occurs through the roof? More than any other area of a building, the roof makes the most difference to thermal regulation inside. Installing roof insulation is the best way to help prevent heat loss through the roof, and can lead to significant savings on your energy bills.

Benefits of roof insulation

Installing roof insulation is one of the smartest and environmentally-friendly decisions for any home or commercial building. It is an investment that will reward you with many short and long-term benefits. Check out the main ones below.

1. Comfortable indoor space

Roof insulation utilises natural resources to help keep inside spaces cool when it’s hot outside and warm when it’s cold outside. Insulating your roof is one of the most important steps to take towards regulating indoor temperatures.

Use roof insulation in conjunction with other savvy techniques for the best results. For example, using passive architectural design techniques, making sure all air leaks are sealed and painting your roof in a pale colour.

2. Reduce your emissions

With a comfortable living space, you are less likely to reach for the remote to your air conditioner or heater, thus reducing your energy consumption. If you do turn them on, having roof insulation will mean it will take less time and energy to cool down or warm up the space.

This reduction in energy consumption is why installing insulation is one of the first things you should do if you want to make your home more environmentally friendly.

3. Save on your energy bills

If roof insulation has helped make your indoor space maintain a comfortable temperature, and you’re using less energy to keep it that way, you will quickly see reductions in your energy bill. And who doesn’t like to save a bit of money?

4. Protect the roof from damage

Depending on your roof, installing the right type of roof insulation could help prevent moisture build up and increase the lifespan of your roof. This is another way insulating your roof could save you time and money in the long term.

Types of roof insulation

Typically roof insulation is a combination of foil-faced roofing blanket and roof batts.

Foil backed insulation works by reflecting radiant heat away from the inside of a building when it is hot outside.The foil layer also helps to resist moisture build up. For optimal results, the reflective foil layer should face a 2.5cm space of air. Beware that dust build up or damage to the foil layer will reduce its reflectivity and hence its effectiveness.

Roof batts work by trapping millions of pockets of air which help resist heat flow in either direction, meaning in winter they will resist the flow of warm air from inside to outside. In summer they will resist the flow of warm air from the outdoors, keeping the indoors cool.

Insulation products are given an R-value depending on their level of resistance to heat flow. The higher the R value, the higher the resistance. The R-value that is best for you will depend on the climate your building is in.

Roof insulation products have several other variables that are important to keep your eye out for such as their environmental benefits and whether they use low allergen materials. Also, keep in mind some can be installed as a DIY while others require the safe handling of a professional.
