Home renovation is an important project for homeowners as it allows them to improve home equity and curb appeal, especially when doing the exterior.

Upgrading homes with carefully thought-out renovation ideas, like replacing traditional windows with energy-efficient windows, can help save money. With professional guidance from experts of Perfect Choice Exteriors & Bathrooms, you can plan to replace the existing windows of your home with special types of windows that make homes more energy efficient.

This article should help you choose the right type of windows for your home that perfectly blends energy conservation with aesthetics. The labels of windows provide information about energy ratings, and proper installation is the key to achieving the desired level of insulation. From fixed windows to hinged windows and insulated windows, there are several options to choose from. Besides the window style, the quality of the glass and frame contribute to the insulation grade.

1. Hinged windows

Hinged windows provide better ventilation and home insulation over sliding windows that have a slight overlap, which leaves some gaps through which air passes. As hinged windows open outward and the sash of the window sits firmly on the frame on closing, it creates almost an air-tight environment. Casement windows, awning windows, and hopper windows ensure the same kind of insulation despite differences in the hinge placement.

2. Fixed Windows

If energy efficiency is more important than functionality, then it is best to opt for fixed windows that create an air-tight seal around the frame and prevent any leakage. Since you will never try to break the air-tight seal of the window (except in case of burglary), place the windows in places that do not require ventilation. However, you can install fixed windows only selectively because of its inability to provide ventilation.

3. Insulated Windows

Insulated windows are a modified version of fixed windows that have recently become popular because of the innovative design consisting of double slashes. Providing two layers of glass makes the windows more energy efficient as the air gap between the glass panes significantly reduces heat transmission compared to traditional fixed windows. The double glass design lowers the Solar Heat Gain Co-efficient (SGHC) and the U-Factor. Recent improvement in the window design includes filling the gap between the glass panes with some inert gas that provides an extra layer of insulation.

4. Energy Star Windows

The National Fenestration Rating Council (NFRC) provides the energy rating of windows after testing, and you will find the information on the window's label. The most energy-efficient windows earn the coveted Energy Star rating displayed by a blue sticker. The government also provides certification for Energy Star rating based on testing performance.

5. Low E- Windows

Besides the quality of the glass panes of windows, the outer surface quality of the panes matters a lot in home insulation. Low E windows have glass panes coated with low-emissivity materials that boost thermal performance and are known as.

Windows play a significant role in enhancing the energy efficiency of homes, and since replacing windows is more affordable than replacing roofs, the demand for energy-efficient windows is increasing.
