Designing Doors for Energy Efficiency
A well-designed door welcomes guests and protects the home from the elements. Whether it is a handcrafted wood entry door or a custom garage door, energy efficiency is one of the most important and often overlooked aspects of performance design. At CAMBEK, we believe beauty and efficiency should coexist. Every door we craft enhances a home’s architecture while contributing to overall comfort and sustainability.
Here’s how thoughtful door design improves energy efficiency.
Why Energy Efficiency Matters in Door Design
Doors are among the most frequently used components of any home, and they are also one of the most common sources of air leakage and heat loss. An energy-efficient door reduces drafts, maintains consistent indoor temperatures, and helps lower heating and cooling costs. For luxury homes with expansive entries or custom garages, energy efficiency is a key design principle that enhances comfort, longevity, and sustainability.
At CAMBEK, our handcrafted wood doors are engineered for exceptional performance, craftsmanship, and visual appeal.
Start with Materials That Insulate Naturally
Wood is one of nature’s best insulators. Unlike metal or fiberglass, solid wood helps regulate temperature by reducing the transfer of heat and cold. That is why we use Douglas Fir and Western Red Cedar, two premium species known for their balance of strength, stability, and insulating properties.
- Douglas Fir provides a dense, stable core structure that resists warping and enhances thermal performance.
- Western Red Cedar offers lightweight durability and exceptional dimensional stability, minimizing heat loss while maintaining natural beauty.
Together, these materials create a door that feels warm in winter, cool in summer, and timeless year-round.
Precision Fit and Craftsmanship Prevent Air Leaks
Even the best materials cannot perform efficiently without a precise fit. Air infiltration, or tiny gaps around the edges or seams of a door, is one of the leading causes of energy loss in homes.
Each CAMBEK door is custom-built to exact specifications, ensuring an airtight fit within its frame. We use mortise and tenon joinery, a time-tested construction method that provides structural integrity and prevents movement or shifting over time. Our precision milling ensures every joint, seam, and seal aligns perfectly with the door’s design and the home’s architecture.
High-quality weatherstripping, thresholds, and multi-point locking systems create a tight seal that keeps conditioned air in and the elements out.
Incorporate Insulated Glass While Maximizing Light
Glass lites bring natural light into a home and elevate a door’s aesthetic. To balance performance and beauty, we use insulated glazing units (IGUs) that feature double or triple-pane construction. These sealed units reduce heat transfer while maintaining the clarity and character of decorative or privacy glass. Options such as frosted, reeded, or laminated glass enhance privacy and energy performance by reducing solar gain and minimizing drafts.
Finishes That Protect and Perform
A quality finish defines how a door looks and how it performs. Our three-coat water-based nano finish system provides a flexible, breathable barrier that resists cracking, fading, and moisture intrusion. This advanced coating technology enhances durability while reflecting harmful UV rays, reducing exposure to heat and extending the life of the finish.
Choosing the right finish, whether a clear coat that reveals natural grain or a painted surface that complements the home’s exterior, ensures both visual harmony and long-term energy efficiency.
Engineered for Performance and Longevity
Every CAMBEK door is engineered for real-world performance. Our doors handle a wide range of climates, from the frozen Midwest to humid coastal regions. Features such as insulated cores, high-performance seals, and reinforced structural frames reduce thermal bridging and maintain stability through seasonal changes.
These design considerations improve comfort, lower energy consumption, and extend the lifespan of one of the home’s most important architectural elements.
Sustainable Design from Start to Finish
Energy efficiency and sustainability go hand in hand. As part of our commitment to responsible design, CAMBEK sources materials from responsibly managed forests and builds doors that are made to last for generations. We also contribute to reforestation by planting ten trees for every custom door we sell, helping offset our environmental impact and restore natural ecosystems.
Beauty, Craftsmanship, and Efficiency in Every Door
Energy-efficient design and timeless craftsmanship belong together. When thoughtfully designed and expertly built, a door becomes both a work of art and a high-performance feature of the home. At CAMBEK, we combine architectural integrity, fine craftsmanship, and modern engineering to create doors that embody lasting beauty, comfort, and efficiency.
