External Weinor blinds and awnings don't just extend your living space they can boost energy efficiency too, says Ainslie Dunn. Preventing the sun from directly hitting window and glass doors is one of the best ways to control indoor temperature's. External blinds in a sunscreen fabric can reduce solar heat gain by up to 90 percent with out impeding views. In turn, this reduces the need for air-conditioning and thus your carbon footprint.
It's most important to shade glazing on the northern and western facades as they receive the most direct sun.
