Government regulations on buildings are becoming more stringent, and cost of heating keeps going up, it is becoming more important to install efficient energy double-glazing as an effective way to keep your house warmer and quieter. A double glazed window uses two sheets of glass with a gap between, which acts as an insulating barrier. Some of the benefits of using an energy efficient window are as below.
Benefits of double-glazing
• Smaller energy bills
Depending on their energy efficiency rating by British Fenestration Rating Council (BFRC), the higher the score, the more energy-saving it is. It can save you money per year on our energy bills, as less heating is required to heat your house.
• A smaller carbon footprint
By using less fuel to heat your homes, you will generate a less amount of carbon dioxide (CO2) making you environmental friendly. As carbon dioxide leads to increased global warming.
• A more comfortable home
Using double glazed windows, heat loss is reduced and your home will have fewer draughts and cold spots.
• Peace and quiet
Insulated windows keep the unwanted noise outside. Less noise means less stress or anxiety, which can be caused by the unnecessary racket. The sound proofing mechanism can be an ideal solution if you live close to a busy road.
• Reduced condensation
Compared to classic windows, glazed windows have less condensation on the inside, which builds up when there is less ventilation.
The benefits of double glazed windows will differ with each household, depending on how much you pay for heating fuel, the size, material, type of glazing and installer. Types of double glazing system will differ with the needs of your home and regulations of your area before you choose below are options you need to look out for:
What to look out for
• Type of glass
The low emissivity (LOW-E) is made of glass making it the most energy efficient option for double-glazing. The glass has been made with an invisible coating of the best metal oxide on one side of the internal panes. It allows light and heat through but reduces the amount of heat that escapes.
Acoustic glass consists of two or more sheets of glass bonded together with one or more inter layers. The interlayer’s act as a noise-dampening core, which weakens the sound as it travels through the core.
Double glazed windows can be very time-consuming and an environmentally polluting process when it comes to cleaning. Self-cleaning glass means that windows can stay clean all year round.
• Gaps between the glass
The gaps between the sheets of glass can have gases such us argon, krypton and xenon to make the window more efficient.
• Pane spacers
The two glass panes are separated by using pane spacers set around the inside of the edges. Efficiency increases when there is little or no metal inside, often known as warm edge spacers.
• Frame materials
Most common type of window frame in double-glazing is uPVC (unplasticized polyvinyl chloride) the structure is three times cheaper than traditional wooden structures, it is recyclable, durable and energy efficient. It is easy to clean, as it requires little wiping down with a wet piece of cloth and a spot of washing liquid now and then.
Alternatives to uPVC include aluminium/steel or wooden frames. Many people feel wooden frames look nicer and more subtle than uPVC. Wooden frames require maintenance and often used in conservation areas where original windows had timber frames.
Composite structures have an inner timber frame covered in aluminium or plastic. It reduces the need for maintenance and ensures the frame is weatherproof.
• Window energy rating
When choosing double glazed windows, you need to check the British Fenestration Rating Council (BFRC) energy label. Any window rated B and above is endorsed by the energy saving trust. It is similar to the one you might have seen on your home appliances like fridge or washing machines. Unfortunately, there is no obligation for window manufacturers to label their products. The rating varies with A being the best to G being the worst.
Energy rated windows would have a u-value of the window displayed on the energy label. A u-value is a measure of the amount of heat that can pass through a material, thus, the higher the u-value, the greater the amount of heat that can pass through.
