Choosing the right patio and entry doors can make a big difference in your home's comfort, energy bills, and curb appeal. This article explains the best energy-efficient door options available today. You will learn about different door types, materials, and features that help save energy and increase your home's value.
Energy efficiency in doors means they help keep your home warm in winter and cool in summer. Doors that are not energy efficient let heat escape or enter, causing your heating and cooling systems to work harder. This increases energy bills and may make your home less comfortable.
According to the U.S. Department of Energy, doors and windows can account for 30% of a home's heating and cooling energy loss (DOE Energy Saver). Choosing energy-efficient doors reduces drafts, prevents heat loss, and keeps indoor temperatures steady.
Energy-efficient doors can also:
• Lower utility bills by improving insulation.
• Reduce your carbon footprint by using less energy.
• Increase your home's resale value and curb appeal.
Because doors are a major part of your home’s envelope, finding the right energy-efficient door is a smart long-term investment.
There are several types of energy-efficient doors to consider, each suited for different spaces and needs. The most common types include:
1. Patio Doors
Patio doors provide access to outdoor areas such as decks or patios. They come in different styles:
• Sliding Patio Doors: These doors slide open horizontally on a track. They save space and offer wide views.
• French Patio Doors: These doors swing open from the center, often with two panels. They provide a classic look and wide openings.
• Hinged Patio Doors: Similar to French doors but usually with one large panel that swings open.
2. Entry Doors
Entry doors are the main doors you use to enter your home. They need to be secure, weather-resistant, and energy efficient. Common styles include:
• Single Entry Doors: One door panel, usually with a solid or glass design.
• Double Entry Doors: Two door panels that swing open, often used for grand entrances.
• Entry Door with Sidelights: Adds a glass panel on one or both sides to bring in more natural light.
3. Speciality Doors
Renewal by Andersen also offers specialty doors designed for specific needs.
The Ensemble™ program that we offer includes distinct panel families and dozens of styles, with a wide range of colors, textures, grilles, and glass options to fit any home.
One of Renewal by Andersen’s key features is our exclusive Fibrex® composite material. Fibrex is a proprietary blend of wood fiber and a thermoplastic polymer. It offers several energy-saving advantages:
• 2x Stronger than vinyl: Provides excellent structural strength that helps the door maintain its shape and seal.
• Resists warping and cracking: This ensures long-lasting performance even in extreme weather.
• Low thermal conductivity: Fibrex reduces heat transfer better than aluminum or vinyl frames, improving insulation.
• Eco-friendly: Made partly from recycled wood fibers, Fibrex has a smaller environmental footprint.
This material helps our replacement doors keep your home insulated and comfortable year-round.
Renewal by Andersen uses high-performance glass options designed to reduce heat loss and block harmful UV rays. Some of these glass choices include:
• Low-E (Low Emissivity) Glass: A thin coating reflects infrared heat, keeping warmth inside in winter and outside in summer.
• Double or Triple Pane Glass: Multiple layers with inert gas fills improve insulation.
• Heat-Blocking and Sound-Reducing Glass: Enhances comfort and privacy.
The right glass package can significantly impact your door’s energy efficiency.
Renewal by Andersen replacement doors are custom-made to order. This ensures an exact fit for your home’s openings, which reduces air leaks and drafts that can happen with off-the-shelf doors. A precise fit means better insulation and less energy loss.
Proper installation is critical for energy efficiency. Renewal by Andersen provides certified master installers trained specifically on their products.
