Vertical and horizontal window blinds are effective in reducing summer heat gain, though not as effective at preventing heat loss during the winter. Interior: There are numerous openings between blind slats, which makes it difficult to control the loss of heat. However, during the summer the slats provide flexibility. Unlike shades, you can adjust blind slats to control ventilation and control light.
Exterior: Exterior blinds can be made of vinyl, wood, aluminum, or steel. They can be mounted over the window, with side channels guiding them as they are raised and lowered. When the blinds are completely lowered, the slats meet providing shade.
Drapery has the ability to reduce heat gain and loss, depending on the type of fabric and the color that you choose. There is a wide variety of options. Windows that receive direct sunlight during summer are better suited to closed drapery. Ideally, they should have white plastic backings and be of medium color. This will reduce the heat gain by up to 33%. They also remain cooler during the summer months, this is because their folds and pleats lose heat via convection. In the winter months, they can reduce the loss of heat by up to 10%. So, you should ensure your drapery is closed over at night to keep the heat in and the cold out.
When shades are properly installed they are one of the most effective, and simplest, energy saving window treatment. They should be mounted tightly against the glass to create the perfect seal. During the summer, shades should be lowered where windows receive a lot of sunlight. While for shades facing the south- lower them during winter evenings, and keep the shades raising during the day.
To create even greater efficiency, opt for dual shades. You can opt for one dark side, and a light side and alternate them with the seasons. The light side should face the warm side, so during the summer the light side should face out, and in the winter, it should face in. Cellular shade increase the insulation, with multiple layers.
Interior and exterior window shutters can assist in reducing heat loss and gain in the home. For shutters on the interior, you need a clear space to each side of the window while they are open. They’ll also need hardware fastened to the trim or window jams. Properly designed shutters can provide excellent insulation. Exterior shutters provide added security, and protection from weather. They can also be integrated with the architecture of the home.
Solid shutters create an insulating shutter, while also providing a decorative covering. When fit closely against the window frame they offer an insulating air space between the window and the shutter. Additionally, shutters can be used in combination with other window treatments, such as curtains or drapery. There is no need for interior panels to be custom made to fit the windows, however these are available. Because of this, interior shutters cost less than exterior shutters.
