Cobus Lourens from a leading wooden window and door manufacturer, Swartland, offers some insight into the many benefits of choosing energy-efficient windows for your home.
“Going green” has become an extremely popular topic in the construction industry. Cobus Lourens, national sales manager at a wooden window and door manufacturer, Swartland, offers some insight into the benefits of installing “green” windows in homes.
Lourens notes that, by selecting well-insulated windows, energy loss can be significantly reduced: “In recent years, windows have undergone a technical revolution – today’s energy-efficient windows facilitate lower heat loss, less air leakage and warmer window surfaces for improved comfort and minimal condensation.
“Double-glazed windows, such as Swartland’s double-glazed wooden windows for example, can reduce the amount of energy you need to warm up and cool down your home by as much as 50%.
“When it comes to insulating our homes, windows are the worst culprits for energy loss – it has been estimated that approximately 40% of all energy loss in a home occurs through standard, single-pane windows,” says Lourens.
Additionally, according to Lourens, energy-efficient windows also reduce the peak heating and cooling load in homes.
Cobus explains that non-energy-efficient windows can create drafts in the winter: “Poor performing windows have very thin glazing, which will cool any air next to the window, and since cool air drop – this air will drop to the floor. This pattern will eventually set-up an air movement pattern that will make your interior feel draughty and it will accelerate heat loss. Energy-efficient windows on the other hand, will offer a higher interior window temperature in winter and avoid this from happening – making the interiors that much more comfortable.”
What’s more, is that wooden products often strike the perfect balance between form and function. Lourens explains: “Daylight and access to outdoor views are two of the fundamental attributes of any window. Unfortunately, however, windows can also be the source of significant solar heat gain or loss. However, today’s advanced glass coatings and window designs will allow you to brighten your home with an abundance of natural light, without worrying about heat or cooling loss. Energy-efficient windows are, for the most part, built out of quality materials – so they will be more durable and add value and charm to the overall aesthetic of any home they grace.”
Apart from being aesthetically pleasing, wooden windows feature excellent insulating qualities, notes Lourens: “Wood is an extremely efficient insulator – recent independent tests conducted by the South African Fenestration and Insulating Energy Rating Association, for example, show that some of Swartland’s wooden windows had the lowest tested U-rating of all tested windows in South Africa at that time.”
Lourens concludes that wood is a renewable resource, making it one of the greenest building materials.
