Pelmets

Pelmets are a decorative and practical addition to any room. They add an elegance and formal finish to windows and block light coming into the room. When teamed with fitted lined curtains, pelmets will improve the energy efficiency of a home by preventing a convention cycle transferring heat through the window.

AJM Custom Designs manufactures upholstered, painted and timber pelmets. We also construct pelmets for corners and bay windows.

Pelmets Reduce Your Energy Costs

NSW electricity prices will rise by 44-62% over the three years from July 2010.

Heating and cooling contributes to about 38% of your home’s energy use. Up to 50% of unwanted heat is gained through windows and up to 40% of heat can be lost from windows.

Pelmets reduce heat transfer through your windows, which reduces the amount of energy required to keep your home comfortable. Pelmets, together with heavy lined drapes are more effective at reducing window heat transfer than double glazing.

Window treatment heat transfer comparison shows that pelmets can contribute significantly to window insulation.

Heating and cooling your home accounts for almost 40% of your power usage.

How Pelmets Save you Money

During a summer’s day, the temperature outside is higher than the internal temperature of the home. The external air warms the glass of the window and, in turn, the internal air which is in direct contact with the glass. As this air is heated it will rise and make its way into the room space. Cooler air from the room will move to fill the space near the window and also be heated, creating a convection cycle.

With normal or poor fittings curtains it is impossible to contain this warm air and prevent it from entering the room space. However, a pelmet prevents this rising air from moving up from behind the curtain into the room itself and stops the convection cycle. This reduces the cooling that is needed during summer.

 In the winter, we heat the internal air in our home which rises to the ceiling. The temperature outside is lower and cools the glass of the window and in turn the internal air which is in direct contact with the glass. As this air cools it falls back to the ground level and warm air from over the window will move pass the windows, cooling and creating a convection cycle.  

Once again a pelmet prevents the warm air from inside the room coming into contact with the glass. It significantly reduces heat loss which normally occurs through the window, reducing the heating that is needed during winter.
