Does My Home Need Insulating?

Yes, practically all homes need, or at least benefit from thermal insulation. The benefits of thermal insulation come on many levels, but basically boil down to one thing; helping to maintain a comfortable temperature in your house throughout the year. Thermal insulation acts like a barrier to heat transfer. During hot weather, it restricts the amount of heat that enters your home, helping to keep your house cool. In the colder months, insulation helps to prevent heat generated within the house from escaping through the walls, ceiling and underfloor.

Thermal Insulation Can Also Significantly Reduce Your Power Bills

Technically it is possible to maintain a comfortable indoor temperature without installing insulation, but this comes at a significant cost. During the winter months, a lot of heat generated inside many older homes literally goes through the roof due to a lack of adequate ceiling insulation. This means that their heating systems have to keep on generating more heat to maintain the desired temperature, which continues to pass through the roof. Ceiling insulation acts as a barrier for heat transfer, basically trapping much of the heat inside. In the past, when energy prices were cheaper, roof insulation was often seen as an optional extra if the home owner could afford it. These days it seems that the situation is different. Now it appears that the average working family can’t afford not to install ceiling insulation. In fact, many people report having earned back the initial investment within the first few years through substantially lower energy bills.

Heating and Cooling Systems Work Too Hard in Homes Without Insulation

Air-conditioners often start to experience problems when they have been worked too hard for too long. There are a number of factors that can contribute to air conditioning overload, one of which is inadequate thermal insulation. During hot weather, the idea is that the cooling system brings down the temperature to the desired level and then switches itself off. Without an adequate level of ceiling insulation, however, heat from the sun will literally be poured continually into the home. This makes it unlikely that the air inside the home will ever reach the desired temperature on very hot days and the cooling system will run constantly. Most systems are not designed for such high use and start to experience issues in the long run. As such, householders who are trying to save money by skimping on ceiling insulation may well be paying up eventually, potentially in the form of a replacement air-conditioning unit sooner rather than later.

Insulation as a Once Off Investment

While it does take a bit of effort and organising, the beauty of installing ceiling insulation is that when the job is done it’s done. The manhole is closed and the insulation can be expected to last for the life of the home. Many brands come with either a life time guarantee or at least 50 to 70 years, which effectively is the life of the home. This means that a once off investment will result in ongoing thermal comfort and yield savings on energy bills year after year.
