Energy efficiency is one of the biggest reasons homeowners in New Jersey look into window replacement, especially as energy bills rise and older homes struggle with insulation. Many homeowners begin researching windows because their current units show signs of heat loss, drafts, or air leakage whenever the wind blows. That search often leads to Andersen energy-efficient windows, a product line known for strong thermal performance, ENERGY STAR-certified products, and long-lasting materials that help reduce energy use year-round.
Andersen windows balance high energy performance, modern engineering, and customizable glass construction, making them one of the most reliable energy-efficient options for homes in New Jersey’s mixed climate zone. These products help limit heat transfer, reduce solar heat gain, and improve whole unit performance through durable frame materials and advanced Low-E glass coatings. Whether you want to lower energy costs, introduce better insulation, or upgrade your home’s windows for superior performance, Andersen’s technologies offer meaningful improvements.
If you’re planning replacement windows for your property, American Home Contractors NJ provides expert installation backed by deep knowledge of Andersen products and climate-specific recommendations for homes across North and Central New Jersey.
Why Andersen Energy Efficient Windows Stand Out
Andersen Corporation has a long history of engineering energy-efficient windows that reduce energy use and help homeowners save money. Their energy-efficient features include insulated glass packages, durable Fibrex composite frames, and Low-E glass coatings that block harmful UV rays. Many Andersen windows also include argon gas blend between glass panes, increasing insulation and improving U-Factor values.
Another benefit is that Andersen produces a wide selection of window types, including picture windows, double-hung windows, and awning windows. Each style is designed to meet ENERGY STAR program requirements when paired with the right glass package. These windows can reduce heat loss in winter, limit heat gain in summer, and help maintain a comfortable indoor temperature without overworking heating and cooling equipment.
Because of these features, homeowners can improve their home’s energy efficiency while maintaining aesthetic preferences and long-term durability. The result is a window system that balances design, energy savings, and low maintenance performance.
How Energy Ratings Explain a Window’s Performance
When researching windows, homeowners often compare energy labels to understand how a product prevents heat transfer, blocks UV rays, and reduces heat gain. These labels come from the National Fenestration Rating Council, which measures energy performance through standardized testing. Understanding these values makes it easier to choose energy-efficient windows that comply with most building codes and regional climate needs.
Key Performance Ratings to Know
The most helpful rating categories include:
| Rating | Definition | Why It Matters |
|---|---|---|
| U-Factor | Measures how well a product prevents heat loss | Lower U-Factor values mean better insulation and less heat escaping |
| Solar Heat Gain Coefficient (SHGC) | Measures how much heat enters through the window | Lower SHGC values help reduce heat gain in hot climates |
| Visible Transmittance (VT) | Amount of visible light entering | Higher VT means more natural light while still managing heat |
| Air Leakage | Air movement around the window frame | Lower leakage improves whole unit performance |
These categories explain how well a window will reduce energy use, improve comfort, and limit conducting energy through the frame or glass.
Because New Jersey experiences both cold and hot climates seasonally, homeowners benefit from products that balance insulation and solar control.
American Home Contractors NJ can help you compare these ratings during a window replacement consultation.
Choosing the Right Glass Construction for Maximum Energy Efficiency
Glass construction contributes significantly to unit performance. Andersen offers multiple insulated glass choices, including dual-pane and triple-pane glass. Triple pane glass includes a third sheet of glass and additional air space, providing better insulation and reducing the amount of heat that escapes during winter. It also limits unwanted heat gain, making indoor temperatures more stable.
Low-E coatings are another major component of maximizing energy efficiency. These coatings help reduce energy loss by controlling the amount of UV rays and solar heat that pass through the glass. In some cases, Low-E coatings also provide a subtle tint that enhances thermal performance without affecting views.
Dual Pane vs Triple Pane Windows
Triple pane windows offer:
- better insulation thanks to additional air space
- superior performance in cold climates
- less heat entering during summer
- reduced noise and higher comfort
Dual-pane windows still provide strong energy performance, especially when paired with advanced Low-E coatings. Many homeowners choose dual-pane windows when upgrading older windows because they offer strong value and still exceed Energy Star requirements.
Specialized Glass Options That Improve Energy Savings
Andersen’s glass packages include several advanced coatings that help reduce energy costs and support public health by blocking harmful UV rays:
- SmartSun Glass reduces heat gain and blocks up to 95% of UV exposure.
- PassiveSun Glass allows more solar warmth, ideal for shaded homes or winter comfort.
- Low-E4 Glass improves insulation and reduces condensation.
These options create energy-efficient products that align with the ENERGY STAR program’s standards issued by the Environmental Protection Agency.
Comparing Andersen’s Most Energy Efficient Window Series
Andersen manufactures several window series with strong whole-unit performance. These include:
Andersen A-Series
- Triple-pane glass is available
- Strong thermal performance in cold climates
- Designed to exceed ENERGY STAR certified window requirements
Andersen E-Series
- Aluminum-clad wood construction
- Excellent customization for window type and frame design
- Strong energy-efficient features for architectural homes
Andersen 400 Series
- Reliable insulation with dual-pane Low-E glass
- Balanced energy performance for most New Jersey homes
- Low maintenance and high durability
Whether you choose A-Series, E Series windows, or the 400 Series, each line supports energy savings, reduced energy costs, and improved indoor comfort.
How Andersen Energy Efficient Windows Reduce Energy Bills
Energy-efficient windows can reduce energy bills by limiting heat loss, reducing air leakage, and preventing heat gain from sunlight. Multi-pane glass, insulated frames, and advanced Low-E coatings create a barrier that helps stabilize indoor temperature even when outdoor weather fluctuates.
Because these windows work to reduce energy consumption, homeowners often see a noticeable drop in cooling costs during summer and heating costs during winter. Energy-efficient products can also lower a home’s carbon footprint by reducing reliance on HVAC systems.
ENERGY STAR reports that ENERGY STAR-certified windows can reduce energy bills by about 13 percent. This savings grows over time, helping offset the investment in new windows.
Best Andersen Window Types for Energy Efficiency
Window type contributes to performance as much as glass construction. Some window types naturally offer tighter seals and better insulation.
- Casement windows and awning windows typically provide the strongest insulation because they seal tightly against the frame.
- Picture windows offer high energy performance due to their fixed glass design, eliminating air movement.
- Double hung windows are popular for ventilation, but may require more frequent sealing to maintain superior performance.
Selecting the right window type for each room increases overall home energy efficiency.
How Energy Efficient Windows Increase Home Value
Installing new windows can raise a home’s value and market appeal. Buyers often prioritize low-maintenance, energy-efficient windows because they reduce energy costs and provide long-term comfort. Homes with ENERGY STAR-certified windows often appeal to eco-conscious buyers looking to reduce their carbon footprint.
Because Andersen windows combine design flexibility, modern energy-efficient features, and durable frame materials, they enhance both curb appeal and home efficiency.
Why Professional Installation Matters
Even the best windows cannot deliver superior performance without proper installation. Installation errors can cause air leakage, heat loss, and reduced whole unit performance. Professional installation ensures that each window is properly sealed, aligned, and supported according to manufacturer instructions and most building codes.
