Replacing heat in winter or cool air in summer that you’ve lost through your windows and doors can be expensive and bad for the environment. Making the switch to energy efficient home and building glass can not only help you do your bit for the planet but can also stop you almost literally throwing your money out of the window.
Read on to find out everything you need to know about energy efficient glass; what it is, where you can get it, and why you need it in your home, office, or building.
What is energy efficient glass?
Energy efficient glass normally makes use of special coatings and double glazing to increase its thermal properties.
At PG glass, they have both double glazed units and ‘Low-E’ glass solutions. The double glazed units consist of two panes of glass help apart by metal. The Low-E building glass products, however, are even more energy efficient. They make use of a clear coating which reflects heat, meaning that on war days your home or building will stay warm inside, and on hot days the heat will be reflected outside, reducing your need for air conditioning and heating. Not only will you save money, but you’ll save the environment bit by bit too.
Why the switch from normal glass to energy efficient glass?
You know the situation. It’s stifling in the office and you and your colleagues are sweating. What’s the advice given? “Open the windows.” It sounds sensible, but when it’s sweltering outside, this seems to do little to help cool you down. What if your windows could actually help solve the problem?
Windows are a common source of heat loss and heat gain, especially in a climate as harsh as South Africa. Research in the UK has shown that an astounding 26% of heat loss occurs through windows, even when they’re closed.
When you consider the cost of underfloor heating (or indeed, air conditioning in the South African summer months) that is a significant amount of money that you’re losing even when you dutifully close doors and windows and do your best to keep the air trapped inside.
There’s also the matter of the environment and your carbon footprint. Reducing your carbon footprint through energy efficient glass is easy and might just keep the planet healthier for generations to come. If you weren’t convinced enough already, National Building Regulations in South Africa stipulate that for new building projects or renovations, your glass replacements and new glass must be energy efficient. So, if you’re planning on building or renovating, energy efficient glass doors and windows are truly the only option!
What if you just went for double glazing?
Compared to standard single-glazed windows, double glazing would certainly make a difference. However, true energy efficient glass is still the most efficient option and is a worthwhile investment. While double glazing alone can increase efficiency significantly, using a good coating can further increase windows’ energy efficiency by up to 25%.
