Glazed windows have been around for years to provide daylight and ventilation. Numerous studies have shown that health, comfort and productivity increase by having well-ventilated indoor areas as well as access to sunlight.
Window glass can treat in order to lower the sunlight energy that is transmitted through it. The type of glass that you pick can aid you:
- Reduce heat loss during winter
- Reduce heat gain during summer.
Single glazing insulation windows let in heat in winter and increase heat in summer. Double glazing can be a more efficient window, but there are techniques. You can apply it to the windows and glass to decrease the sunlight flowing through them.
Windows are, however, an important source of warmth loss and discomfort and condensation issues. In the year 1990 alone, energy use to offset the unwanted heat loss and gain through windows in commercial and residential buildings cost the United States $20 billion (one-fourth of the energy use to heat and cool the space).
Why Is Glazing Important?
Make a choice of smart glass to improve the atmosphere and ability to live in your home. For untrained eyes, one glass panel may look like the other. But choosing the right glass for your home makes a big impact on everyday life in your home.
There are many elements that need to be considered when choosing glass, and taking stock of your needs and priorities will make decisions easier.
Sunlight
The glass allows light to flood your home, but it can be hot and UV damage. In the corners that are cooler than home, warmth may be a blessing that is welcome but in the north and west that faces your home can be steamy and fade your carpet, furniture or curtains.
Noise
If you live in urban areas with high density, traffic, neighbours and transportation noise may be something you have to learn to overcome.
Adding an acoustic glass range to your window and door will significantly reduce the noise brought to your home. Improve your sleep quality by adding acoustic glasses to your bedroom, or sinking the sound of the freeway nearby, the train path or the overhead flight path.
Energy Efficiency
Do you want to reduce electricity bills and reduce your carbon trail? Using glass to maintain warmth in winter and reflect heat in summer is a smart way to reduce the need for AC and heater. Low E glass and fast glass will increase temperature control in your home, or invest in double glass to achieve home ranking.
What Are The Performance Requirements For Window Glass?
Let’s first look at the two main purposes of the glass in creating a physical barrier, and letting light flow from the outside into the inner. Everything that is important about window glass performance is related to these basic properties.
As a physical barrier, the single glazed window insulation contributes to the thermal efficiency of the window as well as its resistance to impacts. The more effectively the glass insulates the inside from the exterior and the lower energy is needed to maintain the same temperature between inside the glass and outside.
Thermal performance can measure by the U-value. It provides the amount of thermal transmission per hour and square foot. The lower the U-value, the less heat energy is transmitted through the glass. That means a lower U-value will result in greater efficiency in thermal energy.
The resistance to the impact of glass is not an establish measure; however, there are a few points to consider:
In General, The More Solid The Glass Pane Is The More Likely It Will Break.
If the glass is tempered through the process of thermal tempering which involves heating and rapid cooling or laminated, it’s regarded as safety glass. Tempered glass can last longer and is more resistant to breaking, and should it break. It’ll break into smaller pieces that are not jagged.
Laminated glass is made of the appearance of plastic laminate material. That is applied to the surface that ensures that the glass pane is held together even if it breaks. Combining tempering and laminating offers the most effective protection against glass breaking and glass debris that results from it.
Impact resistance and thermal efficiency do not always have the same priority for window glass if your maximum size is restricted. For instance, a huge one-inch-thick pane of glass will break less easily. Than a set comprising two quarter-inch glass panes, with the equivalent of half-an-inch gas between.
(That combination of double glazed windows and doors and gases is known as the glazing package. We’ll discuss more of that in a minute.) A glazing package is sure to have a better thermal efficiency perspective.
What Is A Glass Package?
Once you’ve figure out the key glass’s performance let’s take a look at how the final product is designed to enhance its efficiency. We’ve talked about something we call “best double glazed windows ” earlier. It consists of at the very least two glazing panes and gaps between them.
The spacers place at all the edges of the package of glazing in order to create a seal area is form within the glass. This chamber will fill with a gas which has low thermal transmissibility which is usually Argon.
By stacking an unglazed glass pane, an insulating gas layer and a second glass pane the glazing package can achieve an extremely low U-value (thermal transmittance) without losing visible transmission (because the gas has virtually no effect on the transmission). Triple glazing is the exact process, but with a different layer of gas, another glass pane and a glass pane added.
How Can You Incorporate The Knowledge You Have Gained About Gazing Into Your Window Purchase Choice?
If you’re purchasing European windows or traditional double-hung windows. You’ll need to begin with the same question when evaluating your options for glazing: Which location is where the project is situated? We’ve already discuss the location of your window can make an important difference. When it comes to choosing the appropriate glazing.
In colder climates, you’ll need an extremely low U-value (i.e. the thermal transmittance is low to protect your interior from the cold weather outside) and an extremely high solar heat gain as well as a large visible transmittance. When you’re in hot environments, you’ll need a low U-value; however, you want the sun’s heat gain to lower the load on your air cooling.
Another thing to consider is that a window that has less solar gain has a lower transmittance to light. You’ll have to find the perfect equilibrium between your efficiency objectives and the visible transmission you’re after.
With your specific location in mind and knowing how the various performance requirements of the glazing are relating to each and each other, you can begin looking for the best glass for your needs. Government agencies and non-profit organisations which issue recommendations on glazing for various climate zones are a good starting point.
The Passive House Institute US (PHIUS) provides a chart free of performance suggestions in both glazing and fully assemble windows on their site. Making sure the glazing of your windows complies with these guidelines will ensure that. The performance of the glass is compatible with the requirements of your home.
Glazing For Windows For New Construction
Double Or Triple-Glazing
Double-glazed windows are extremely energy efficient since they reduce heat loss or gain by nearly 30% compare to windows made of aluminium that are single-glazed. Double glazing is a significant contributor to a 6-star or more energy-efficient house and is readily accessible.
Tips On How To Choose Double-Glazing
The distance between two glass pieces should be at a minimum of 12 millimetres and then fill with Argon gas to ensure the best performance.
If you’re considering double-glazing to cut down on noise A gap of 50-100mm shell is utilises. It is important to note that this can decrease the thermal efficiency that the windows provide.
Triple glazing can perform better than double-glazing to lower the cost of cooling and heating and is the ideal choice in more cold Victorian climates.
Low Emission Glass (Low-E Glass)
In the state of Victoria, applying a Low-E coating on the glass’s internal surface. It can help to make your home warmer in the winter months by reflecting the heat of the sun back into space.
The Best triple glazed windows are typically utilise as a supplement to double-glazing in order to minimise the loss of heat in winter through windows. Low-e glass to limit the heat loss isn’t advise for Victorian conditions because it decreases solar gain during winter.
Secondary Glazing To Replace Windows
Secondary glazing can describe as an additional piece of glass acrylic. That is fitted to existing single-glazed windows using magnetic strips or incorporate into the frame that is already in place. It is usually a less expensive alternative to triple or double glazing.
Base on the type of product and its capability in creating an air gap between the windows that are currently in use. The additional layer might be able to duplicate the characteristics of windows with double glazing.
Triple glazed conservatory is the most popular way to improve the energy efficiency of old windows since they keep the character of the window.
