Do you notice drafts or pockets of cold air around your windows during the winter? Does sunlight coming through window glass add heat to rooms during hot weather? Although windows play an important function in buildings by letting in light and fresh air, they are also a source of heat transfer and energy loss. In cold weather, cold air infiltrating through windows affects comfort. During warm weather, heat transfer makes air conditioners work harder to keep rooms cool. There are many ways to make windows more energy efficient and reduce drafts. One of the simplest is to use thermal curtains and other window dressings to create a barrier between hot and cold spaces.
What To Look for in a Thermal Curtain

The best thermal curtains are made with several layers of fabric, creating a dead-air space between the curtain and the window. This slows the transfer of heat and reduces drafts, which increases indoor comfort and energy efficiency. Older types of insulated curtains were often unattractive, heavy and bulky. Today's thermal curtains are lightweight, stylish and easy to install.

Insulated curtains are usually made of two, three or four layers of materials. The layer that faces into the room can be made of any type of attractive fabric, including velvet, polyester, patterned cottons and linen. The weave, color, design and texture add style to the window treatment and overall room décor. The inner layer contains insulation, usually made of felt, foam, flannel or thick cotton. The back layer can be made of several types of materials, including plastic, polyester, foam or foil that helps reflect heat and sunlight. Often, the backing is also a vapor barrier. However, some manufacturers add a vapor barrier as a fourth layer.

These layers are compressed together to form a lightweight but effective drapery that helps maintain indoor temperatures, retard drafts and reduce solar gain. These features are also noise-reducing and light-filtering. Blackout curtains, soundproof curtains and thermal curtains have similar properties, which is why thermal draperies are often marketed as blackout or noise-filtering curtains.

The size of the panels affects how well thermal curtains work. Measure your windows to determine the size and number of panels you need. Curtains should extend several inches beyond the sides of the window for a more effective thermal barrier. Hanging panels several inches above the top of the window keeps air from flowing over the top. Curtains that drop to just above the floor or puddle on the floor are better at stopping drafts. However, curtains that rest on the sill or extend to just below the sill can also work if they fit snugly against the window frame.

More fullness adds volume, which reduces drafts and looks more aesthetically balanced. To determine how many panels to install, experts recommend a measurement that is double or triple the length of the rod. The header style also contributes to the effectiveness of the panel. Gathered styles, such as rod pockets and back tabs, create a solid expanse of fabric that helps keep drafts out. Well-constructed grommet headings have the same effect.
