The ultimate heat conductor is glass and this allows the energy to escape easily. Many old or traditional windows are designed with single panes which are placed in aluminum frames and this further lessens their already dreadful energy efficiency. These days, residential areas can lose almost 20 to 30 percent of cooling and heating energy through their doors and windows. For this reason, replacement windows were designed to solve such problems encountered from older windows.
Since glass conducts heat efficiently, experts in the industry linked an old window to a two inch gap in homes wall which freely allows air to escape and which seriously compromises energy efficiency. Inefficient windows cause cooling and heating systems to work overtime just to make the area comfortable. The HVAC systems guzzle excess energy which leads to a much higher utility cost.
U-factor measures emissivity and R-value measure heat loss resistance. Many old windows hold poor U and R values since these are made of untreated single pane glass which is highly vulnerable to heat absorption and transfer. Low emissivity energy efficient windows put off heat energy from escaping through the window, separating your conditioned indoor environment from ambient outdoor temperatures.
You have to understand that old windows constantly transfer energy and conduct heat. You can make use of replacement windows since these are designed to prevent absorption and transfer, to preserve home interior temperature while resisting various changes because of outside weather. Bear in mind that replacement windows have the ability to make you more comfortable while allowing you to save a great sum of money too.
If you’re considering replacing old windows to improve energy efficiency of your home, you’re not alone. This is one of the best ways to cut back cooling and heating costs and vital for retaining hear in the cold months. If you’re still puzzled, below are three warning signings which clearly indicate that you need replacement windows:
- Once your windows encounter frost build up or condensation, touch the glass. If it feels freezing cold in the winter or hot to the touch during summer, this indicates that it requires replacement.
- During winter, sit beside your window for a minute. If it feels much cooler compared to other parts of the house, this is a clear sign that you are losing heat due to inefficient windows.
- When window panes start to crack or window frames start rotting or cracking.
A number of homes are still using old or original built windows with single pane glass because of their fear of spending great amount of money. But keeping old windows which are no longer energy efficient can end up costing more over time than replacing your windows now. The 3 mentioned signs above clearly indicate that your window badly requires replacement. If you’re already encountering these indicators as the winter season is approaching, you should consider getting replacement windows now before temperatures drop even further. Don’t let your old windows hike up your bills and waste energy – get replacement windows now and start reducing your costs!
