Energy-efficient doors are essential for maintaining a comfortable indoor environment and reducing energy costs. At the core of their performance is the insulated core, an engineered feature that prevents heat transfer and provides superior thermal efficiency.
Let’s explore how these cores work, the materials used, and what makes doors from brands like Avanti, North Star, and Dorplex ideal for homeowners seeking energy savings.
Insulated Cores: The Heart of Energy-Efficient Doors
Unlike most doors in your home, the exterior door has specialized layers to avoid heat transfer. The core of an energy-efficient door acts as a thermal barrier, keeping the warm air in and the cold air out. These cores are made from highly engineered materials like polyurethane or polystyrene foam, which trap air and resist heat flow. Let’s look at both of these types:
Polyurethane Foam Cores
Polyurethane foam is one of the most effective insulating materials. As a dense structure, it offers a high R-value (a measure of thermal resistance), making it an excellent choice for doors in extreme climates. This material is lightweight, durable, and resistant to moisture, perfect for exterior weather-facing doors.
Polystyrene Foam Cores
Polystyrene foam is another popular core material, offering consistent insulation and affordability. It’s commonly used in doors that balance energy efficiency with cost-effectiveness. While it provides slightly less insulation than polyurethane, it remains a reliable option for moderate climates.
Energy-Efficient Features in Our Top Door Brands
Avanti Collection
Avanti doors combine a polyurethane foam-filled core with Owens Corning weather-stripping, creating a complete energy-efficient package.
North Star Collection
North Star doors are engineered for Canadian winters, featuring polyurethane foam cores paired with a wind-resistant frame.
Dorplex Collection
Dorplex incorporates a solid polyurethane foam core, which promises five times greater insulation value than wood doors.
Comparing Core Constructions: What to Look For
- Material Type: Polyurethane offers the best insulation, while polystyrene provides a budget-friendly alternative.
- Sealing Systems: Weather-stripping and frame sealing significantly impact overall energy efficiency.
- Durability: High-quality cores resist moisture and maintain performance over time.
Why Insulated Cores Matter
By minimizing heat transfer, insulated cores in exterior doors lower heating and cooling costs and reduce your home’s carbon footprint. Therefore, even if the investment is higher upfront, over time, you will likely save more on monthly HVAC costs and maintenance for your door.
