Replacement, Safety & Performance
Get to know your windows and doors. Learn about replacement, safety, and performance.
The following information and external links have been provided for your convenience.
When To Replace Windows
- Single Glazing
- Single-glazed (-pane) windows are the least energy efficient due to allowing the highest transfer of energy – heat loss or heat gain depending on the local climate.
- Inoperable Parts
- An inability to smoothly operate windows can be a nuisance. A window that doesn't shut properly will create energy and security issues.
- Seal Failure
- If a draft occurs around a closed window, it could mean the seal has failed. The result of seal failure is wasted energy and money.
- Warm / Cool Spots
- Check for warm or cool spots near the inside of the window on a hot or cold day. If you find any, it means the windows are not insulating the house.
- Condensation can be expected to form on windows given the right conditions. Double-glazed (-pane) windows can significantly reduce it with its superior insulating properties.
- Outside Noise
- When outside noises can be heard clearly, it may be time for noise control. Single-glazed windows are not the most effective barrier against noise.
- Fading Furniture
- UV rays entering through windows can lead to fading of furniture, carpet, window treatments, and artwork. More energy efficient windows can potentially reduce the fading.
- Upgrade Home
- Consider replacing old windows with new windows that can aesthetically perfect your home's architecture. The end result will prove to be a worthy investment.
How To Select Windows
- Assess Your Windows
- Assess whether your windows should be repaired, retrofitted, or replaced. While most new windows have labels indicating their energy properties, such information is not often available for existing windows.
- Look For
- A NFRC label is needed for verification of energy code compliance. It displays whole-window energy properties, appears on all fenestration products, and provides the only reliable way to determine the window energy properties and compare products.
- Compare Annual Energy Costs
- Use the Window Selection Tool to compare the annual energy performance of different window types and design conditions for a typical house. Find manufacturers who offer windows within the generic results shown. Learn more about manufacturers' specific product options.
- Customize Energy Use
- A computer simulation program, such as RESFEN, lets you compare window performance options by calculating performance based on utility rates for your climate, house and window design options.
- Choose A Durable Product
- Make sure the design and workmanship results in a durable product for your specific application. Window warranties can be an indicator of the reliability of the window and its manufacturer. Durability may vary with location.
- Ensure Proper Installation
- Proper installation is necessary for optimal window performance. To ensure an airtight fit and avoid water leakage, always follow installation guidelines and use trained professionals for window installation.
