Anatomy of an Energy-Efficient Exterior Door

Exterior doors play crucial roles in your home’s energy efficiency. They keep unwanted drafts out and trap desirable indoor heat. As they weatherproof and insulate your home in an uncompromising manner, they lower your energy costs month after month for decades.

To take your home’s energy performance several notches higher after your doors installation, Renewal by Andersen® of Kansas City recommends looking for these key features:

Multiple Panes

Unlike their interior counterparts, exterior doors must have glass to admit natural light and frame outdoor views. However, products with plain, clear glass offer little protection against the sun’s infrared and ultraviolet rays. The former is responsible for excessive heat gain while the latter causes solar damage on your valuables.

Much like windows, all energy-efficient exterior door systems should have at least two panes of glass for exceptional insulation. Anywhere in America, double glazing is the standard to resist heat transfer.

At Renewal by Andersen of Kansas City, dual-pane door units feature an argon gas blend for fill and a spectrally selective multi-layer Low-E coating. These components work together to resist the sun’s unwelcome rays while letting most visible light through.

Compared to ordinary glass, our Low-E technology makes your home more energy-efficient by at least 45% and 56% more in the winter and summer, respectively.

Insulative Core Material

Both our hinged and sliding doors have laminated veneer lumber. Constructed under intense heat and pressure, the wood substrate of our exterior door systems wouldn’t bow, warp, and pull apart with extreme temperature fluctuations.

In addition, our doors come with solid wood jambs. Their sill is made of aluminum with a built-in thermal break. The laminated veneer lumber core of our door panels are encased in a waterproof finish.

All in all, the design of our doors lend them excellent insulating and moisture repellence properties. Requiring no painting, our products are not prone to any form of structural damage over time. With little maintenance, they can preserve their pristine condition and exceptional thermal performance.

Weathertight Edges

Our hinged French doors guarantee maximum weathertightness. Unlike typical inswing and outswing door systems, the weather-stripping of our products are on the panels, not the jambs. They have a gasket that runs continuously on all four sides of our doors. Since they have no seams, air, water, and dust have no chance to enter your home when closed.

Moreover, our French doors are equipped with a five-point locking system. Other than security, activating all points of the lock pulls the two panels together tightly for optimum weathertightness.
