With the sweltering heat of the current climate, many homeowners are wondering how to cool their homes without spending a fortune on installing and running an air-conditioning unit. The answer is as simple as it is affordable – ensure your home is fitted with high-quality insulation.
When most people think about insulation, they picture a heavy winter coat protecting them against the cold weather, or perhaps an insulated travel mug keeping their coffee warm. For this reason, many homeowners underestimate the importance of good home insulation in hot climates.
In truth, insulation goes far beyond keeping things warm – take refrigerators and freezers, for example, which need ample insulation to keep food cold. It is the same for your home: good insulation prevents heat from escaping in winter and keeps hot air out in summer.
How insulation works
To understand the benefits of a well-insulated home in a hot climate, you first need to understand how insulation works. Insulation is a thermal barrier that prevents the transfer of thermal energy into and out of the home. Put simply, insulation prevents heat from entering a home in the summer and keeps heat inside during winter.
So how does it do this? Insulation works by trapping small air bubbles within the material’s structure. Air is an incredibly efficient insulator when confined, and insulation works by trapping pockets of air within its structure. Since warm air always travels towards a cooler space, whether it is warm outside and cool inside, or cold outside and warm inside, the insulation will prevent the warm air from travelling across the barrier – thereby doing its job and keeping your home warm in winter and cool in summer.
Saving on your energy bills
The effect of insulation is twofold: it not only prevents warm or cold outdoor air from entering your home but also prevents cool or warm interior air from escaping, which means your air conditioner or heating appliances won’t have to work quite as hard. Overall, a well-insulated home can save you up to 20% on the electricity needed to keep the space at a comfortable temperature. The bottom line is that good insulation will help your home better resist outdoor weather changes, keeping the interior more comfortable.
The added benefits of insulation
Aside from keeping your home cool in summer and warm in winter, insulation can also help protect your home from fire. Knauf mineral wool insulation has a Euro Class A1 fire rating and a SANS 10177 Part 5 Fire-rated Certification. The non-flammable nature of Knauf insulation also provides fire protection for your home – the insulation becomes a “hard target” that the fire would have to burn around, thereby slowing the spread of fire by up to 57%. Furthermore, Knauf insulation is also resistant to insects, termites, rodents, vermin, mould, mildew, and fungus, providing even more protection for your home.
Consider the environment
By saving energy, you are reducing the use of non-renewable resources, thereby doing your bit to reduce greenhouse gas emissions. If you are interested in living a ‘green’ lifestyle, insulation can go a long way toward helping you achieve it. Since insulation allows you to use less energy and, in return, produce fewer emissions, you’ll reduce your carbon footprint and your impact on the environment.
Selecting earth-friendly insulation, such as world-leading Knauf mineral wool insulation, also helps maximise your home’s eco-friendliness. Knauf mineral wool insulation boasts a high recycled content, primarily derived from naturally occurring materials. It also features a revolutionary binder technology called ECOSE® Technology, which has cemented its place as a truly sustainable building material. It offers reduced environmental impact through lower embodied energy and diminished manufacturing emissions and workplace exposures.
