7 Ways to Save Energy With Your Windows That Aren't a Pane

Remarkable advances in glass technology have led to the development of low-emissivity (low-E) glass to replace inefficient single-pane glass. Its invisible thin layers of metallic oxide selectively reflect heat while allowing visible light to pass through. In the summer, low-E glass blocks heat from the sun’s rays during daylight hours and prevents heat loss in the winter when the heat source is warm indoor air.  

Two glass panes separated by argon or krypton form a highly insulating window. Also known as dual-pane windows, double-pane windows are very effective at blocking thermal radiation. Providing high thermal insulation and minimizing cooling costs is a more cost-efficient way to keep indoor temperatures at desirable levels.  

Single-pane windows allow warm and cold air to interchange freely, resulting in large temperature swings during the day and night. Adding storm windows can reduce these fluctuations. Designed for interior or exterior applications, a storm window is placed inside or outside an existing window to prevent air infiltration and minimize heat loss.  

Air leakage around windows and doors can lead to drafts, high heating costs and wasted energy. Weatherstripping reduces gaps between window sills and frames, reducing air movement and improving thermal insulation. Alternatively, caulking is used to plug holes and cracks in window frames, sills, joints and between window sashes so that air cannot escape.  

Style, privacy and natural light control are the primary reasons for using window treatments such as blinds, draperies, shutters and shades. However, heavy drapes block out light and trap warm air inside the house during the colder months. On the other hand, adjustable shades eliminate glare, regulating sunlight and airflow without heating the room.  

Versatility and ease of application make reflective window insulation film a popular choice. It’s easy to cut, fits most windows and operates quietly. Solar control films reflect heat and UV rays to keep your home cooler by reducing solar heat gain. Thus, they share the workload with your AC to speed up the comfort level in your home and provide you with lower energy bills.  

Over-reliance on HVAC systems to maintain interior temperatures during sun-soaked seasons can result in high cooling costs. Fortunately, there are cost-effective ways to reduce the need for air conditioning and better manage your energy consumption. Exterior shading solutions like awnings, shutters and overhangs block direct sunlight from entering your home with minimal heat buildup.
