Energy Efficient Window Design Features

Given the fact that our global population continues to grow at an exponential rate, increasing our environmental footprint, there is a greater focus as of late to sustainable living, building and manufacturing. There has also been a focus on reducing dependency on energy and conservational efforts.

The most recent manufacturing technologies of a replacement window has achieved both goals in responsible manufacturing design and the reduction of home energy costs as a result. A newer design is the tilt & turn, but are UPVC Tilt and Turn Windows Worth Buying?

Replacement windows that meet Energy Star guidelines

Energy Efficient Windowinclude features such as insulated glass panels, high performance heat reflective coatings, dual weather stripping and warm edge spacers. Other sustainable design features include the use of super spacers between two glass panes, which reduce condensation, preventing the undesirable loss or gain of heat, and prevent seal failure.

By reducing condensation between widow panes, there is a much lower chance of developing bacteria, mold, fungi, virus and mites that could lead to respiratory infections, allergies and asthma.

Glass and replacement windows

manufactured in the United States also requires more rigid construction practices, but ultimately ends up with a higher quality and more sustainable window. Specific manufacturers have earned a “Cradle to Cradle Silver Certification” in the United States, marking their higher quality manufacturing rating based on building materials, construction practices, and the window’s impact on the environment once the life cycle is over.

Specialized coatings

also improve the efficiency of the window. Consumers should look for Solarban 60 and 70XL Low-E glass windows for maximum insulation, keeping cool air in the home during the summer and retaining warm air during the winter months. This technology also reduces the bright glare of sunlight without reducing the total amount of light let into the home, which is due to the layers of silver metallic oxide coated on the windows.

Lastly, the use of vinyl in window manufacturing has become the new standard. However, not all vinyl windows are built with the same technology and specifications, as some lack proper insulation. Most consumers do not want their air-conditioned or heated homes leaking precious energy dollars. It is important that the energy efficient windows be injected with foam in the jamb and header. Properly constructed and designed vinyl windows will save energy by reducing unwanted solar heat and expanding natural light transmittance while also blocking much of the sun’s damaging UV rays, thereby maximizing efficiency.

Windows that are made here in the United States ensure greater quality control, design and energy efficiency standards, and lower costs with faster delivery time-frames.

For the best value for the home with the lowest maintenance and greatest environmental benefit, look for Energy Star rated windows that include the above design features and benefits at
