When it comes to energy efficiency, the importance of the exterior doors pales in comparison to windows. However, this is only true because the latter generally outnumbers the former. With their lower glass-to-frame ratios, patio doors, even glazed ones, actually provide better thermal insulation than windows can.
Since not all “energy-efficient” doors are equal, however, ENERGY STAR® says that following should be the characteristics of an effective, energy-efficient patio door system:
To reduce the flow of heat from the inside to the outside and vice versa, double-pane doors are the standard. They contain an insulating gas that helps prevent the heat or the cold from passing through. Most manufacturers, including Renewal by Andersen® of New Mexico, use argon because it’s practically as efficient as krypton but not as expensive.
Further, our doors feature Low-E coatings to reflect the sun’s undesirable rays while letting in daylight. Unlike many of our competitors, we use several layers of spectrally selective, Low-E coatings. In turn, the ability of our contemporary and French doors to prevent unwanted solar heat gain and sun damage and boost daylighting is unparalleled.
Improved Core Materials
Doors with low-maintenance cladding covering solid wood are the norm for a good reason. Hollow-core units are less costly but relatively flimsier. Susceptibility to damage indirectly affects energy performance because any form of structural deterioration can set the stage for air leakage.
Our hinged and sliding patio door systems come with a water-resistant sheath, protecting the substrate from moisture. To ensure long-term, structural integrity, our door sash encases laminated, veneer lumber, and our frame houses treated pine.
Advanced Weather Stripping
For airtight sealing around the edges, continuous weather stripping is necessary. In addition to this requisite component, our patio doors also have an interlocking design to eliminate gaps and keep your interior draft-free.
