The Energy-Efficient Features of Renewal by Andersen® Patio Doors

Energy efficiency is an important consideration when buying new patio doors. Being much larger openings than windows, they can potentially increase or decrease your monthly energy consumption depending on which materials and features you choose.<1–more–>

Renewal by Andersen® Patio Doors Energy Efficiency Features

Fortunately, Renewal by Andersen® patio doors are designed with energy efficiency in mind. Here are some of its features:

Energy-Efficient Glass

Glass is naturally conductive. And given that patio doors are mostly made of glass, traditional single-panel glass can facilitate thermal transfer. This translates to heat gain during summer and heat loss during winter, thereby increasing your indoor heating and cooling requirements and resulting in increased energy consumption.

Our dual panel High-Performance™ Low-E4® glass is installed on all our French and sliding glass doors, designed with energy efficiency in mind. The vacuum airspace between the glass panels act as an insulating layer that minimizes thermal transfer and helps ensure heat stays where it’s needed.

Low-Emissivity Coatings

Invisible infrared rays is the part that makes sunlight hot, making it another unwanted source of indoor heat. Being a form of light, insulation doesn’t work against it. This is where low-emissivity coatings, such as our own Low-E4 coatings, come in. Our patio door glass selectively blocks harmful infrared and ultraviolet rays (the latter being the primary cause of faded fabrics and furniture) while admitting as much natural light as clear glass. The Low-E4 coatings are installed within the airspace to reduce exposure to wear and tear.

Frame and Sash Material

Our patio door frames are durable, requires no maintenance, and have sufficient insulation tested against extreme weather conditions. Our wood frame options are protected by urethane coating or vinyl sheath that enhances its durability and resistance to temperature changes.

Efficient Weatherstrip and Interlock System

The gap between the door frame and the sashes is often considered a weak point in operable windows and patio doors. The right materials wouldn’t be as efficient if the doors aren’t forming a proper seal, hence the need for reliable weatherstripping. Our patio doors feature a weatherstrip and interlock system that seals the doors when closed, further enhancing its energy efficiency.
