External Window Coverings and Thermal Efficiency from JWI Louvres![]() The fundamental function and purpose of exterior window coverings is heat control. External window coverings will prevent excessive solar heat gain and reduce the need for cooling in the summer. It can also reduce, if not eliminate - the high capacity of cooling equipment needed, resulting in a reduction in the initial investment cost. In colder environments, external window coverings will enable the use of solar energy to help heat the building during winter. This is often overlooked when solar control glass is selected for heat control. JWI louvre systems can easily result in reduced energy costs, as well as reduced greenhouse gas emission during the daily operation of a building.
