In Art Deco design, window glazing and treatments were chosen carefully to enhance energy efficiency. Some common types of window glazing and treatments used in Art Deco buildings to improve energy efficiency include:
1. Double-glazing: Double-glazed windows consist of two panes of glass with a layer of air or gas in between them. This design helps to insulate the building, preventing heat transfer between the interior and exterior. It reduces the amount of heat escaping during colder months and prevents excessive heat from entering during hotter months.
2. Low-emissivity (Low-E) coatings: Low-E coatings are thin layers of metallic oxide applied to window glass. They help to reflect heat radiation back into the room, reducing the amount of heat gained or lost through the windows. Low-E coatings also help to block harmful ultraviolet (UV) rays, protecting interior furnishings from fading.
3. Insulated window frames: In addition to glazing, the window frames themselves play a role in energy efficiency. Insulated window frames are designed to minimize heat transfer. They are often made of materials like vinyl, fiberglass, or wood, which have low thermal conductivity and can reduce energy loss through the frame.
4. Window films or tints: Window films or tints can be applied to the glass to reduce solar heat gain. They help to block sunlight and reduce glare, keeping the interior cooler and reducing the need for air conditioning. These films or tints can also help to enhance privacy and protect against harmful UV rays.
5. Insulated curtains or blinds: Art Deco interiors often feature heavy curtains or blinds made of insulating materials like velvet or heavy fabric. These window treatments help to trap air between the window and the curtain, providing an additional layer of insulation and reducing heat transfer.
Overall, the emphasis in Art Deco design was on finding a balance between aesthetics and energy efficiency. The chosen glazing and treatments aimed to enhance the visual appeal of the buildings while also improving energy efficiency and comfort for the occupants.
