Choosing Energy Efficient Windows and Doors?

Answer 1

Energy efficiency should be considered as an important factor in purchasing windows and doors. Energy efficient products are durable and perform well in different climatic conditions. They also come in a variety of designs to suit the aesthetic detail of different types of homes.

Characteristics

Typically, doors that are made of fiberglass, steel, and wood material rank high on the energy efficient list. Steel doors are infused with a core made of polyurethane for better insulating performance. Doors that are equipped with a magnetic strip in the frame are effective in sealing and preventing air leakage.

Energy efficient windows are typically made of the same materials used in manufacturing doors but with the addition of vinyl, composite, and combination materials. Vinyl and fiberglass window frames are solid or filled with insulation foam. Combination frames have components made from separate materials while composites are made from materials blended into a durable product. Window and door panes with low e-coating are ideal for reducing exposure to heat and UV rays.

Measure

Energy Star is a certification program started by the US Environmental Protection Agency (EPA). Any appliance or housing structural component with an Energy Star label has passed the strict standards set by the EPA. Home construction designs should incorporate structural components that are energy star compliant. Labels usually indicate the R-values, U-values, and Solar Heat Gain Coefficient (SHGC) of windows and doors to help consumers in their product selection.

The value of all three energy efficient criteria depends on the location and climate zone. The U-Value and SHGC are more reliable indicators of energy efficiency since they reflect a whole unit assessment rating. U-Values indicate insulating capacity of the product while SHGC reflect effectiveness of the product in blocking heat. A client who prefers a product that helps sustain high interior temperature during colder season should select a lower U-Value rating. On the other hand, a lower SHGC means reduced heat coming in during warmer months.

Benefits

Energy efficient windows and doors facilitate thermal comfort during different seasons. The product should complement the performance of the heating and cooling system by maintaining the ideal temperature inside the house. Energy efficient products also lower heating and cooling bills by preventing cool air leakage or heat loss. Annual heating and cooling costs are reduced since the system does not have to use excess amount of energy. Low e-coated glass on windows and doors also prevent exposure of interior furnishings to harmful UV rays and help reduce fading and damage.
