Energy-Efficient Sunrooms: How Betterliving® 366 Glass Improves Year-Round Comfort
Energy-efficient sunrooms give you more than beautiful views and natural light. They create a comfortable living space you can enjoy during the heat of summer, the cold of winter, and every season in between.
Because sunrooms contain more glass than most rooms in a home, choosing the right glass is essential. Ordinary glass allows outdoor heat to enter during the summer and indoor warmth to escape during the winter. Betterliving® Year-Round Sunrooms address this challenge with Betterliving® 366 Glass, a high-performance insulated glass system designed for four-season comfort.
Why Glass Matters in Energy-Efficient Sunrooms
The glass in a sunroom has an important job. It needs to provide clear outdoor views and plenty of daylight while helping control the movement of heat into and out of the room.
Without energy-efficient glass, a sunroom can become excessively warm in direct sunlight and more difficult to heat when temperatures drop. That can make the room less comfortable and place greater demand on its heating and cooling equipment.
Betterliving 366 Glass is designed to help keep unwanted heat outside during warmer weather and comfortable warmth inside during colder weather. The result is a sunroom that feels more like a natural extension of your home.
What Is Betterliving 366 Glass?
Betterliving 366 Glass is a high-performance Low-E glass used in Betterliving Year-Round Sunrooms.
Low-E means “low emissivity.” The glass has an extremely thin, nearly invisible coating that helps control how heat passes through it. Betterliving 366 Glass features an advanced three-layer coating that reflects heat while still allowing natural light into the room.
Unlike heavily tinted glass, Betterliving 366 Glass maintains a clear, neutral appearance. Homeowners can enjoy an open, bright space without sacrificing the outdoor views that make a sunroom so inviting.
More Comfort During Hot Weather
Direct sunlight can quickly raise the temperature inside a room, especially when there are large areas of glass. Betterliving 366 Glass is designed to reject much of the sun’s unwanted heat before it enters your sunroom. This can help the room remain more comfortable during warmer weather and reduce the demands placed on its cooling system.
The technical measurement for this performance is called the solar heat gain coefficient, or SHGC. This number tells you how much solar heat passes through the glass. Lower numbers indicate greater resistance to solar heat gain. Betterliving 366 Glass has an SHGC of 0.27. In everyday terms, that means the glass is designed to let in natural light while limiting much of the heat that would enter through ordinary clear glass.
Improved Comfort During Cold Weather
Energy-efficient sunrooms also need to perform when temperatures fall. Betterliving 366 Glass is part of a dual-pane insulated glass unit. Instead of having a single piece of glass between your sunroom and the outdoors, the system uses two panes separated by an insulated space containing argon gas.
Argon is a safe, colorless gas that helps slow the transfer of heat through the glass more effectively than ordinary air. This helps retain warmth inside the room and keeps the interior surface of the glass warmer during cold weather.
Why does the surface temperature matter? Sitting beside a cold window can make you feel chilly even when the thermostat is set to a comfortable temperature. Warmer interior glass surfaces help reduce that uncomfortable cold-window effect.
In manufacturer testing, argon-filled 366 glass maintained a room-side center-of-glass temperature of approximately 60 degrees when it was 20 degrees outside and 70 degrees inside. Under the same conditions, standard double-pane clear glass produced an interior glass temperature of approximately 51 degrees.
Actual performance will depend on the complete sunroom design, outdoor conditions, installation, and indoor temperature. However, this comparison demonstrates the difference high-performance glass can make.
Natural Light Without a Dark Tint
Homeowners choose sunrooms because they want to feel connected to the outdoors. That experience depends on natural light and a clear view. Betterliving 366 Glass allows approximately 65% of visible light to pass into the room. This provides an excellent balance between daylight and solar control, creating a bright, inviting space without admitting as much unwanted heat. The glass also has a neutral appearance, helping preserve the natural colors of your outdoor surroundings.
Protection Against UV-Related Fading
Sunlight can gradually fade furniture, flooring, rugs, curtains, artwork, and other interior finishes. Ultraviolet rays are one of the leading causes of this fading. Betterliving 366 Glass blocks approximately 95% of UV transmission through the glass. Although no window can completely prevent fading, this additional protection can help preserve the appearance of the items inside your sunroom. This is especially valuable in a space that receives several hours of sunlight each day.
Energy-Efficient Glass Is Only Part of the System
While glass plays a major role in energy-efficient sunrooms, the entire room must be designed to work together. Betterliving Year-Round Sunrooms combine Betterliving 366 Glass with thermally broken aluminum framing and an insulated roof system. Thermal breaks reduce the direct transfer of outdoor temperatures through the aluminum frame, while the insulated roof helps control heat entering and escaping through the top of the room. When combined with professional installation and properly sized heating and cooling equipment, these features help create a comfortable space for year-round use.
Several additional factors can affect a sunroom’s overall energy performance, including:
- The size and orientation of the room
- The direction of the sun throughout the day
- Local weather and temperature patterns
- Shade from trees or nearby structures
- The room’s connection to the existing home
- The type and size of its heating and cooling system
- The quality of the installation
An authorized Betterliving dealer can evaluate these factors and help design a sunroom that matches your home, climate, and plans for the space.
