Energy Savings from Solar Shading

Solar Heat Gain Coefficient (SHGC)

Crimsafe Security Screens are the best product to protect your home or property from being broken into by burglars, but did you know that they are just as good at protecting your home from overheating?

Adding Crimsafe screens on your windows and doors can greatly reduce the amount of heat entering your home, therefore reducing the need to run the air-conditioning and thus reducing your energy costs. In fact when a Crimsafe screen is added over the whole window, it can improve the window's ability to block solar radiation by up to 52%.

Windows play a very important role in the fabric of our homes. They allow in light, control airflow, and provide views that connect our internal living space with the outdoors. However, ordinary windows can also represent a major source of unwanted heat gain in summer and significant heat loss in winter. 


A major element of determining a windows' energy rating is its Solar Heat Gain Coefficient (SHGC). Basically, the SHGC is the measure of how well a window blocks heat caused by sunlight. The lower the value of a window's SHGC, the less solar heat it transmits.

Crimsafe Security Screens, when applied over the whole area of a single glazed window can improve the SHGC of the window by 52%. Considering that up to 40% of a home's energy for cooling or heating is lost or gained through windows this can represent a huge saving on your energy bill and a dramatic cut in your greenhouse gas emissions.
