Insulation – Fact or fiction
For many of us in the sub-tropics there’s a myth that going around that simply defies the laws of science.
Heat descends and cool rises!
Before you fall into the trap of trying to keep your home cool in summer, consider the simple fact that heat rises, and trapping it under your ceiling insulation isn’t going to help reduce the temperature in your room. Ideally in the many high set homes in Queensland, it’s the floor that you need to insulate to prevent the cool air from an air conditioner transferring from your living space to the ground floor.
Ideally, to create an ideal insulating Queensland home, you need to prevent the heat from transferring into your roof cavity, this is best accomplished by roof sark and creating an insulating barrier at the point of transfer. Installing ventilation ports in your roof cavity to evacuate hot air will also help. Consider these issues before deciding whether a ducted or a multiple split system installation would suit your home.
The addition of flooring insulation accompanied with some ceiling fans to stir the cool low lying air is a better strategy along with mounting your head unit as high as possible to process the hotter air higher up. Preventing cool air escaping down stairways and other descents is part of the task C.E.A performs to add value to all it’s installations.
