It’s important to choose windows that will not only be right for your home’s aesthetic, but also the climate where you live. Very interesting article ! Low-e coated glass is used to minimize solar heat gain, while suspended coated film is used to maximize insulating performance, block UV radiation, reduce noise, and increase occupant comfort more effectively than coated glass alone. This type of glass is more resistant to condensation than single or double glazing and in colder climates, will help your home be more energy efficient. Single-pane glass may keep out the weather, but it does little to insulate against heat loss or reflect the sun’s heat—its performance is about R-1 (i.e.

*We do not sell your e-mail address to 3rd parties, we simply forward their offers to you. thanks for sharing with us. Remember, though, while bronze and gray tints reduce solar heat gain, they also reduce visible light transmission. They are available in different styles and window frames, and have a lower price point, compared to double or triple glazing. This option is just like double pane, but with a third piece of glass. It is important specifiers know the performance limitation of dual-pane glass, or the weight limitation of triple-pane glass, need no longer be accepted. The air space inside dual-pane insulating glass (i.e.

Well-insulated ‘solid’ walls are typically the priority for a specifier when designing for cold climates, but they do not offer the esthetic appeal and natural daylighting benefits of glass. If you’re looking for a solution to reduce heat and glare, solar window film can be installed to existing glazing to alleviate common solar problems, such as excessive heat and annoying glare. The best-kept secret about improving commercial building energy efficiency is high-performance window glass. Also, it’s important to remember that this type of glass option isn’t necessary for all different types of climate zones.

Superior multi-cavity solutions that incorporate suspended coated film have changed the rules and can achieve up to R-20 glass performance without additional structural weight.

This means despite having a lower R-value, an R-20 glass unit may actually outperform an R-30 wall.

This material is known as a spacer and can be constructed of different types of material. No reproduction without expressed written permission. Suspended-film insulating glass uses multiple films to achieve at least R-8 (i.e.

Different types of windows are designed to perform based on whether you’re in a predominantly heating or cooling climate, as well as those areas in between. Click here for instructions on how to enable JavaScript in your browser.

Heat and Glare entering through windows is a problem all year round – but fortunately they can be alleviated with Window Film.

For example, as stated above, suspended-film insulating glass can reach a performance of up to R-20. By Bruce Lang

At this point, the glass is stopping 95 per cent of the potential heat loss (U-factor 0.05).

Products available by the metre, in various lengths.

Triple-pane insulating glass Windows (specifically window glass) must: Additionally, many windows must also open to provide ventilation and egress in case of emergency. It is used to upgrade and improve the thermal performance of existing glazing. High-performance glass options

Suspended-film insulating glass Unlike dual-pane glass (which is limited to a single cavity), multi-cavity glass uses multiple insulating air spaces to achieve a new level of energy efficiency. In summer, solar heat gain entering through windows can lead to uncomfortable temperatures far above the optimum of 21-23°C.

There are hundreds of options to consider, from the glass to the frame to the style and finish. Walls with an insulating performance of R-30 (i.e. RSI-1.4) insulating performance and moderate solar heat gain.

Calculate the cost of heat lost per square foot of the window by multiplying your fuel cost per unit by the number of degree days. For example, a building designed with low-performance glass will likely require additional systems, such as perimeter heating and a larger HVAC system. Videos, Case Studies and further information on this product is available in our Media Section, or by using the links on the right.

RSI-3.5)—with krypton gas and three suspended films—at the same weight as dual-pane glass. Up to 80 percent of energy loss through a window can occur at its edge. Here’s a closer look at these three options. “As a comparison, Energy Star–rated windows typically hold an R-value of 3. You should always work with a licensed, insured and reputable glass shop that can assess your specific needs and local building codes and offer professional services. Lang has a bachelor of science in electrical engineering from Stanford University and a master’s degree in business administration from Santa Clara University in California. All information published on this website is believed to be

Envelope design and product choices have a significant impact on energy efficiency and occupant well-being.

The low-down on high-performance glass

In addition, the type of material used between the two pieces of glass to create an insulating glass unit can also make a difference when it comes to the window’s level of energy performance.
It is at this point a glass system is capable of outperforming the surrounding wall. In addition to reducing the heat flow, a double-glazed unit with clear glass will allow the transmission of high visible light and high solar heat gain. Improve a buildings energy efficiency, helping to lower a buildings carbon footprint. Thanks alot. Suspended-film insulating glass consists of a coated film suspended between two panes of glass. placed on this website.

However, since there is only one piece of glass, these windows do not offer as much insulating value as other options, and may not keep out as much noise. © 2020 Glass.com Inc. All Rights Reserved.

The increasingly recognized benefits of bringing in daylight include: There is clearly an incentive to make windows perform better. I am building a modern house by the ocean with all commercial fittings. Designed by Elegant Themes | Powered by WordPress, Window Film and Energy Efficient Buildings, clean and quick to install with a minimum of disruption.

This technology refers to the edge construction of an insulating glass unit that conducts less heat or cold than traditional windows.
Air conditioning costs can increase as we attempt to return to this temperature.

NFRC U-factor ratings, however, represent the entire window performance, including frame and spacer material.

Not only does this reduce the building’s initial price, but it also lowers annual operating costs.

By increasing the R-value from 3 to 5, average heat loss through the window is reduced by 30 percent to 40 percent.” Designed for new construction and replacement projects, … Glass that insulates like a wall decrease the ultraviolet (UV) radiation that causes material and furnishing fading; insulate against heat loss–especially during the cold, winter months. For windows, skylights, and glass doors, a U-factor may refer to just the glass or glazing alone. By addressing the problems associated with solar heat gain, glare and winter heat loss, Thermal Window Film can; Our greatest performing thermal window film is known as Enerlogic.

This type of glass is exactly as the name implies: a singular panel of glass. He can be reached via e-mail at blang@southwall.com. 4.

Single pane, clear glass has the highest rate of heat loss or heat gain (depending on the local climate), while permitting the highest daylight transmission. Please check the box below to confirm you would like to be added to Kenilworth Media’s various e-mail communications (includes e-newsletters, a survey now and then, and offers to the design-build industry*). He is also the president of Southwall Insulating Glass, a company that manufactures energy-efficient, suspended-film insulating glass.

Thermal Window Film can be installed to existing glazing to reduce heat loss by reflecting heat back to its source.

This type of glass has a thin metallic coating that lowers the emissivity of the glass. * By submitting, I agree to let ARC Window Films email me from time to time so they can provide me with useful information. High-performance glass enables true design freedom to meet both esthetic and energy efficiency goals.

This energy conservation double standard exists because it is easier to be a wall than a window. Human-centred Design: Simplifying features in building automation.
