Sunroom Windows: Low-Emission (low-E) Glass Sunroom Windows: Low-Emission (low-E) Glass
Sunroom windows are an important consideration when deciding on the construction of a sunroom. A homeowner wants to be sure that the proper type of window is chosen for this particular project before work begins. This will eliminate many problems later on.
Very thin layers of a metal are applied to this type of glass. Some windows will come with as many as 15 layers of coating. The metal may be silver, or another type such as titanium oxide. This is considered a low-emission coating.
How This Window Type Works
The metal layer provides the window with protection. Hot and cold temperatures cannot penetrate the sunroom via the window while internal air temperatures cannot be lost through the window.
Another key benefit of this type of window is that it will protect the home from ultraviolet rays which can ultimately lead to the fading of the floor and furniture. It will also dispel the brightness from the sun without the need for tinting. This can be accomplished without compromising the benefits of a well-lit room to relax in.
Low-emission windows combine three elements to provide perfect efficiency. Firstly, each window has two or three panes of glass. Secondly, they are coated with metal. Finally, they use argon, a naturally-occurring gas as insulation. Two paned windows have one layer of this insulation. Triple paned windows have two layers of insulation. These measures help to eliminate condensation and frost problems that are often evident with traditional sunroom windows.
There are two types of low-emission glass: hard low-emission glass and soft low-emission glass. Their insulation properties are measured by the ‘R-value’. The soft coated glass has a higher R-value than the hard coated glass. A soft coated glass window filled with argon gas will provide the highest R-value. The actual R-value for this type of window is 4.35.
Low-emission glass can be cut into many shapes and sizes to make it a highly versatile choice.
These types of windows can be designed to work with many different sunroom options. Floor to ceiling choices are available, as are shorter windows. Ceiling windows are also possible. Some windows can be opened and closed, and some are stationary.
Cost Cutting Idea
Stationary windows, which are windows that do not open, are priced lower than windows that open and close. To cut costs, use a combination of the two. Put the opening windows where a breeze will be welcome. Put stationary windows in the other locations.
These types of windows have Energy Star ratings and provide a home owner with an indication of energy efficiency within their sunrooms. This will save a homeowner a substantial sum of money over many years by lessening the need for heating and cooling in the room.
Building a sunroom can be a huge undertaking, but is well worth the time. Be sure to research all sunroom options before deciding how to proceed with this project.
