Like I mentioned above, if all this heat was retained in the house throughout the winter, then think of the money you could save on energy costs by not using your heater all day long. This money could be spent elsewhere, perhaps on a holiday or renovation around the house.




An additional advantage of insulation is noise reduction. If your residence is located in a noisy area and you just cannot maintain a calm and soothing environment around the house, then its acoustic properties will appeal to you most. A well-insulated house can significantly reduce noise pollution and will also be easy to sell if you ever decide to in the future.

Colder climates in South Africa like Johannesburg, Pretoria and Cape Town need a thicker insulating material than warmer climates like Durban.

What you need to try and do, is insulate your entire house and seal off areas where air leaks in and out. The ceiling, floors, windows and doors all need to be checked. For windows, you can upgrade to double glazed or even triple glazed. Alternatively, you can look at investing in thicker curtains.




There are various different insulation products available on the market. Some more advanced than the others. If you do happen to use old material then you will be disappointed by its results. Since it will fail to trap the heat within the house. Insulation needs to be done properly installed by professionals. Using the right materials too.

To get your money’s worth, give the installation process the time it needs. Also, you need to get just the right amount of insulation installed for it to work properly.

Before you start the process of installation, find out the time it will take. Some installations could take a couple of hours whereas others require to be done over a course of four weeks.
