Why Settle With Double Glazing When You Can Have Triple?
All Our PVC Double Glazed Windows Can Be Upgraded To Triple Glazing
Low emission glass, also known as low-e glass, is a favourite when it comes to energy-efficient glass. Considering that 70% of energy loss occurs in windows and doors, with 90% of window loss occurring due to glass choice, selecting an appropriate type of glass for your windows should undoubtedly be a priority. Let’s take a closer look at low emission glass and it’s benefits.
Low-e glass is glass with a special transparent coating which reflects heat without minimising the transparency and clarity of the glass, or the amount of light entering your home. Low-e coatings occur at various performance levels and as the coating is microscopically thin, it can be used alongside other coating techniques, including laminating, single glazing and double glazing.
Low-e glass comes in two types of coatings: soft coats and hard coats.
The solar control coating, also known as the soft coat, is applied to pre-cut glass that has already been formed, at room temperature in a vacuum chamber where electricity combines with molecules of metal to cover the glass. It is then sealed in an insulated glass unit, resulting in an almost invisible coating which allows more visible light with reduced haze. The soft coat provides a higher level of performance when compared to a hard coat, however, it is also less durable and can only be used in double-glazed glass.
The more common variety is the hard coat low-e glass, which is made online by coating the glass with a thin metallic oxide layer during production. This welds it to the surface, creating a highly durable fusion which is also difficult to scratch. Hard coats can also be used for single-glazed applications, however, although they are more durable, the haze levels are higher and clarity can be lower than the soft coat variety.
Low-e glass’s main benefit is its ability to reduce heat loss by reflecting interior temperatures back inside the home. However, heat loss isn’t the only problem we encounter when choosing inadequate window finishes. Another common problem we face is damage to our interior furnishings, with curtains and other furniture losing its colour due to the strength of the ultra-violet rays we have in Perth. Low-e glass reduces the strength of ultra-violet rays whilst also cutting glare and thus improving thermal efficiency.
Low-E glass makes your home more comfortable in every season—but how? The coating on the glass acts as an insulator in the winter. It essentially traps the warmth in a building. In the summer time, that coating is also key to keeping your home cool. The low-e glass helps block radiant heat and ultraviolet rays.
What does this all mean? It means lower energy bills each month. Low-E glass reflects heat out in the summer and keeps the warmth inside a building in the winter, leaving your home feeling more comfortable while saving energy.
In addition to energy savings, low-e glass protects from fading. Think about all the sunlight that comes into your entry way. Having low-e glass on your Nu Way Glass door and Nu Way Glass windows preve early fading on hardwood floors, carpet, sofas, curtains ,furniture, . other materials that are affected the suns damaging rays
