Roof insulation can reduce your homes energy bill!

Roof insulation can reduce your homes energy bill!

I bet you didn’t know that over 30% of your homes heating cost could be attributed to the fact your room may not be insulated? The same can be said about over 30% of your comes cooling costs!

Well once you know its quite obvious. Warm air, without something blocking it and left to its own devices, will tend to raise upwards. Whereas colder air will tend to drop. Pretty obvious so far.

Now think how this simple physics interacts with a roof or ceiling without insulation. If your heating a room, that heated air will tend to ‘sit’ against the ceiling – warming the ceiling. So if it is not insulted that warmth gets transfered into the roof space and outside your house! Also the loss of the heat results in the cooler air ‘dropping’ in the room, so you end up with a thermal cycling of the warm air to the ceiling until all the available warmth is lost.. This is very expensive.

A similar thing happens when you try to cool a room but in reverse. During a hot day the roof space gets very hot, and given its a roof with no real holes in it you get a ‘stack’ of hot air sitting in your roof space heating up everything it touches; including the ceiling. So then the ceiling starts to get warm and in turn heats the air against it… Now where are most fixed aircons in homes?.. Yes, right up high on the wall, so they are then trying to cool down already warmer than normal air… Its actually worse than this, as the temperature guage in the aircon unit is constantly measuring the temperature at its on the wall location and not that at floor level, so it will try to ‘over cool’ when it does not need to….

Put both of these together and you will find 40% of both your heating and cooling costs are going out of the roof!
