Saving Energy Costs By Replacing Windows

Living room with big windows

Energy efficient windows are an important consideration for both new and existing homes, as heat gain and heat loss through windows are responsible for 25% to 30% of residential heating and cooling energy use.


You should choose the most efficient windows you can afford that will work best in your climate. Even though your existing windows are in good condition, by taking steps to reduce the energy loss through windows, you can save money on energy bills and make your home more comfortable to live in.


In this article we propose an idea that is often overlooked: how a simple window glass replacement could help modify your homes and business properties, and increase the comfort and savings in your pocket.


 Most home windows are inefficient  


The unfortunate reality is that the majority of windows in new homes are of poorer quality as most home builders do whatever they can to keep their costs low and profits high.


If your home is less than 30 years old, it is more likely that your windows are made from inferior materials to cut costs. On the other hand, if your home is more than 30 years old, it probably does not have any of the energy-saving properties found in modern window technology.


The way to check if you have inefficient windows is if your windows get warmer in the heat, or if they are hard to open or close. If you need a running AC system all day to keep your house at a comfortable temperature, then you could be losing money due to inefficient windows.


 Replacement windows can help you save money  


Replacement windows are normally treated with a low-e coating, and filled with gas that is usually Argon or Krypton. Both systems are manufactured to reduce UV rays that emanate heat, fade furniture, and fill your home with unwanted radiation.


Choosing the right material for your replacement windows can also help you save money. The best material so far is vinyl. If you get the replacement windows made with close to 100% virgin vinyl, they will last longer and not fade or get brittle over time.


 Selecting your new window panel  


If you decide to replace your windows, you will need to decide on the following:

  • Frame types

  • Glazing type

  • Gas fills and spacers

  • Operation types


Other than the window type, you will need to consider the design, energy use and labeling, warranties and proper installation.


Look for the ENERGY STAR label when buying new windows to find the most efficient windows for your needs. You can compare it to the energy performance label from the National Fenestration Rating Council (NFRC) to determine the window’s energy properties and compare products.


You should keep an eye out for low solar heat gain coefficient (SHGC) which is a measure of solar radiation admitted through a window. Low SHCGs reduce heat gain in warm climates like Singapore.


 Installing the glass panel  


Even the most energy-efficient window must be properly installed to ensure energy efficiency and comfort. You should liaise with trained professionals according to the manufacturer’s instructions; if not, your warranty may be void.


The installation is dependent on the type of window, construction of the house and exterior cladding and if there is any weather-restrictive barrier. If you are unsure, you should consult a professional so that they can provide their expertise and ensure that you have a smooth installation process. windo
