  • 7 Facts About Energy-Efficient Replacement Windows

energy-efficient replacement windows are your best protection against heat loss and gain. This is because windows are responsible for up to 30% of residential air conditioning.

Even if your windows are relatively new and do not need to be replaced, you can still take steps to reduce energy loss by caulking or weather-stripping them and applying treatment depending on the season. Below are some of the things you need to know about energy-efficient replacement windows.

1. Replacing Old Windows Is Better Than Repairing Them

The easiest, cheapest option for many homeowners is to fix whatever needs to be fixed and get on with life. This is however not the best option since it does not address the root problem. It is merely a temporal solution. A more cost-effective and efficient way of dealing with the problem is to replace your windows. However, before making a decision to repair or replace a window, talk to a professional home improvement contractor.

2. Frame Type

There are different types of window frames to choose from, each with their advantages and disadvantages. Fibreglass, vinyl, wood, and select composite frame materials are ideal for their high thermal resistance compared to metal frame materials. The problem with metal is it is a good conductor of energy, both cold and heat. It is therefore not a good choice for window replacement frames. The main determinant of the ideal replacement window frame is the climate you live in.

3. Type of Glazing

The glass or glazing type is a key determinant of an energy efficient window. It may sometimes be necessary to have different types of glazing for various windows in your home depending on window orientation, climate, and your home’s design. For best results, get a professional replacement windows contractor to guide you on what your home’s specific needs are.

4. Spacers and Gas Fills

Using gas fills between glasswork layers minimizes heat transfer between your window’s exterior and interior. You use spacers to establish the correct distance between layers and to prevent moisture or gas leaks.

5. Operation

The right replacement window for your home depends on how you will be using it. A lower leakage window improves your home’s overall efficiency. Among the most popular replacement window types are casement, single and double-hung, awning, fixed and sliding. A professional home improvement contractor can give you the information for each window type and recommend the appropriate one for your home.

6. Other Considerations for Choosing Energy Efficient Replacement Windows

The types of frame, glazing, gas fillers and operation are key influences of the most energy efficient replacement window. However, the design, installment requirements, and energy are also key determinants of the appropriate replacement window for your home. Always check the ENERGY STAR rating, which can help you lower your domestic energy bills by 12%. In any case, Energy Star rated windows are environment-friendly. They help to reduce greenhouse gas emissions.

Another consideration for the best replacement window to purchase is your climate. To reduce heat loss, go for gas-filled windows with low-E coatings if you live in a cold area. For better thermal resistance in cold climates, consider U-factor windows.

7. Installation

Installation is key to the optimal functioning of an energy efficient window. If incorrectly installed, most energy efficient windows on the market will not provide you with optimal performance. It may also result in the voiding of the manufacturer’s warranty since it does not cover issues arising from incorrect installation. For best results, always let a professional do it since they have the experience.

Energy-efficient replacement windows are not only cost-effective, but they also help to preserve the environment by reducing greenhouse gas emissions in the atmosphere.
