Venetian blinds are a common fixture on windows for many reasons. Besides reducing the heat entering your home, they are one of the simplest and most economical window dressings. Venetian blinds are easy to use and maintain and give you many options for controlling light coming into your home.
Install blinds on the exterior of your home if your primary concern is heat reduction. Venetian blinds installed on the interior allow up to 40 percent of the sun's heat into your house, according to TargetWoman.com, because the sunlight heats and passes through the glass. Consider a durable form of venetian blind such as wood or metal for outdoor use.
Put blinds on the interior when their main purpose is to control light and restrict outside views into the home. This lets you adjust your blinds on a whim--you can keep them closed, open the blinds while keeping them over the window to allow some light in, or draw the blinds and compact them tightly at the top to allow maximum light.
Install automatic controls that can adjust your blinds based on preset temperature goals, light preferences and direction sunlight hits the window.
Use a wet rag to clean dust off your blinds. Clean the windowsill beneath the blinds to pick up dust and any bugs that died while trapped between the blinds and the window.
