You may not be able to do much about the soaring price of energy, but you can save money in your home by investing in energy-efficient Renewal by Andersen® windows from Mr. Rogers Windows. They're scientifically built to lower the cost of heating and cooling, and reduce the energy needed to keep your home comfortable.
According to Green Seal: "If all windows in the U.S. were as energy efficient as those made by Renewal by Andersen®, Americans would save up to 2.5 percent of the annual U.S. energy consumption - an estimated 200 gallons of oil for every household in the U.S." Replacing old windows and doors reduces your energy consumption and helps to conserve fossil fuels worldwide. Best of all, you save money.
The Science of Energy-Efficient Windows
In the winter, energy-efficient windows keep your home's warmth inside. The most important way energy-efficient windows perform is by keeping heat from passing through your windows. In the summer, this means keeping heat out so your home stays cool, and in the winter, this means preventing the heat inside your home from escaping to the outdoors.
One source of heat is radiation. Radiation is the energy that's transferred from the sun in the form of waves we feel as heat. When the sun's energy radiates down on your windows, the outside of the glass is heated, and that heat is transferred through the glass into your home.
The sun's heat passes straight through conventional windows.
Renewal by Andersen® windows incorporate the latest, energy efficient technologies to help reduce energy costs. Take a look and read how some of these technologies help keep your home insulated and your energy costs down:
Two Panes of Glass
Two panes of glass help block outside heat. Windows with a double layer of glass help to reduce radiant heat transfer from the sun to the inside of your home. Dual pane glass windows have an extra sheet of glass that stalls heat from trying to penetrate through your windows, because it has to pass through the extra space between the panes to get into your home.
Argon gas, combined with Low-E coatings, provides the greatest energy-benefits. An air space left between glass panes helps to reduce the passage of heat through your windows. The amount of space between the two panes of glass can be too wide or too narrow to provide you with the most energy benefit. Through years of testing, Renewal by Andersen® windows have determined the optimum space for maximum efficiency.
Argon Gas Fill
Low-E coatings work to enhance energy efficiency. Argon gas is an invisible, nontoxic, odorless gas that's injected into the space between the dual glass panes. While regular air is easily affected by heat, argon is considerably denser than air. The weight of this gas dramatically reduces the amount of heat that can pass through the space between the panes of glass.
Warm Edge Low Conductance Spacer
Spacers are used to maintain the measured space between the two glass panes and help stabilize the structure of the window. It's important that the spacer material conducts as little heat energy as possible from one pane to the other. Stainless steel is strong, durable, and the top choice for insulating performance when it comes to your windows. That is the material used in Renewal by Andersen® replacement windows.
Windows must maintain airtight seals or risk ruining their energy efficiency. Low-E (low-emissivity) is a thin coating of transparent metallic material that's applied to window glass for insulating purposes. Renewal by Andersen® windows from Mr. Rogers have 9 layers of metallic materials, like silver, applied in a micro-thin layer, followed by 2 layers of titanium dioxide to help make cleaning easier.
The Low-E coating helps to prevent heat gain (or loss) in your home by acting as a kind of reflective shield, pushing radiant heat that tries to pass through the glass back to the source it originates from. In the summer, the Low-E coating reflects the sun's heat away from your home, helping to keep the indoors cool. When winter comes around, the metallic coating holds warm air inside your home, preventing your home's high-priced heat from escaping out through the glass.
By keeping hot air out during the summer and warm air in during the winter, Low-E coatings give you more control over your comfort and save you money on energy bills. Low-E coatings are one of the most important elements in making windows energy efficient.
Heat Deflection Characteristics
The Renewal by Andersen® FIBREX® window frame material is an integral part of how windows keep your home well-insulated and well-protected against heat gain and heat loss. FIBREX® deflects temperatures of up to 221 degrees F. With extreme temperatures in the summer, the sun can heat the exterior surface of your home up to 175 degrees. FIBREX® provides you with the heat tolerance you require to perform flawlessly in summer's blazing heat.
Low Thermal Movement Saves Energy
Thermal Expansion is used to describe the amount a material expands in hot temperatures and shrinks in cold temperatures. When window frame materials expand and contract at very different rates, it causes stresses and strains to the different window parts that result in cracks and gaps where air leakage can occur.
For example, have you ever run hot water over the metal lid on a jar that you can't open? The lid loosens because the thermal expansion coefficient of the metal is greater than that of the glass. The same thing happens from heat on an aluminum or vinyl window. The heat of the sun causes these window materials to expand slightly more than the glass. Over time this thermal effect produces leaks in the window seal and fogged glass.
Now consider FIBREX®. Like glass and the wood framing in your house, FIBREX® has a very low Coefficient of Thermal Expansion, so temperature variations don't loosen the bond or create gaps in the window frame. FIBREX® windows are guaranteed to maintain their airtight seals and insulating properties. No leaks, no foggy glass, and no cold spots!
