When it comes to selecting doors for your home or commercial space, energy efficiency is something to consider. In a world increasingly conscious of environmental impact and rising energy costs, investing in products that meet stringent energy efficiency standards is not just a choice but a necessity. That’s where Eris Home Products comes in, offering bi-fold doors that are not only stylish and functional but also Title 24 accredited for U-Factor and Solar Heat Gain Coefficient.
Understanding Title 24 Compliance:
Title 24, part 6, of the California Code of Regulations sets forth comprehensive energy efficiency standards for both residential and non-residential buildings. These standards are designed to promote sustainability, reduce energy consumption, and enhance indoor comfort. For homeowners and builders in California, compliance with Title 24 is not just encouraged but mandatory.
When evaluating the energy performance of doors, two key metrics come into play: U-Factor and Solar Heat Gain Coefficient (SHGC).
U-Factor: This measures how well a door keeps heat inside a building. The lower the U-Factor, the better the door insulates. Eris bi-fold doors boast U-Factor ratings of 0.30 or better, surpassing the requirements set forth by Title 24.
Solar Heat Gain Coefficient (SHGC): SHGC measures how effectively a door blocks solar heat from entering a building. In climates where cooling is a primary concern, a low SHGC is desirable. Conversely, in colder climates, a higher SHGC may be preferable. Eris bi-fold doors meet SHGC ratings of 0.23 or better, ensuring optimal performance in varying climatic conditions.
Unparalleled Energy Efficiency: With U-Factor and SHGC ratings that exceed Title 24 requirements, Eris bi-fold doors are at the forefront of energy efficiency. By minimizing heat transfer and solar heat gain, our doors help reduce reliance on heating and cooling systems, leading to lower energy bills and a smaller carbon footprint.
Enhanced Comfort: By effectively insulating against heat loss and gain, Eris bi-fold doors create a more comfortable indoor environment year-round. Say goodbye to drafty spaces and fluctuating temperatures, and hello to consistent comfort and savings.
Sustainable Design: At Eris Home Products, we’re committed to sustainability. Our energy-efficient bi-fold doors not only benefit homeowners but also contribute to a greener planet by conserving energy and reducing greenhouse gas emissions.
Exceptional Quality: Beyond their energy-saving properties, Eris bi-fold doors are crafted with precision and attention to detail. From sleek aesthetics to smooth operation, our doors are designed to enhance the beauty and functionality of any space.
Every well-performing structure begins with better materials and smarter construction. Doors play a vital part in that conversation. When chosen thoughtfully, they help regulate temperature and reduce wasted energy without needing constant adjustment or maintenance.
Take a closer look at how thoughtful engineering helps achieve better performance in the long run:
When a bi-fold door forms part of the thermal envelope, its materials and seal must manage airflow efficiently. Otherwise, temperature fluctuations indoors become harder to control, and energy usage climbs steadily with each season.
Consistent thermal resistance does more than reduce monthly bills. It helps keep internal temperatures stable, allowing HVAC systems to work more efficiently. This extends the lifespan of mechanical systems and lowers energy consumption across the board.
Not every door suits every environment. In a state like California, where coastal fog and inland heat exist side by side, energy-efficient design must respond to regional differences. Title 24 accounts for these differences, and so should the products used.
Here’s how regional demands influence the performance expectations of bi-fold doors:
A product that performs well in cool, humid zones may not fare the same in arid inland areas. Builders must match U-Factor and SHGC values to their location’s climate zone to meet regulatory requirements and deliver real comfort.
Doors that meet energy codes across climate zones must be designed with flexibility. Eris bi-fold systems are tailored to achieve compliance across a range of installation environments, supporting builders with fewer product limitations and less guesswork.
Thermal efficiency cannot rest on visual appeal or assumptions. It must be measured, tested and designed into every material layer. That’s what Eris Home Products focuses on when building bi-fold systems that meet Title 24 expectations.
Let’s unpack the technical focus behind Eris doors and their real-world efficiency:
Each Eris bi-fold door undergoes standardized thermal analysis. These figures aren’t approximations. They reflect controlled laboratory evaluations of heat retention and solar resistance, directly supporting regulatory documentation and field performance.
True insulation relies on harmony between components. When glass, seals and internal frames are engineered as a single unit, energy transfer slows down. This coordination defines how well a door keeps the inside protected from outdoor shifts.
Sustainable building is not only about reaching efficiency scores. It’s about choosing components that continue to work over time without premature breakdown. Bi-fold doors must not just pass inspections; they must last with minimal energy input and maintenance.
What follows is a look at how durability plays a role in responsible design. Learn more here:
Title 24 is a baseline. The greater impact lies in making doors that reduce total energy demand over their service life. That means better insulation materials, consistent fabrication, and durable weather performance across seasons.
When doors remain in use longer without repair, replacements drop. That reduces waste. Each Eris bi-fold system is built for repeat use, helping reduce load on materials and disposal systems.
Energy ratings may appear on datasheets, but comfort is something people feel every day. A good bi-fold door should make a room quieter, more temperate and more pleasant, even as outside conditions shift.
Consider how everyday comfort is supported by reliable thermal performance.
Interior consistency depends on how well a door holds back heat, cold and ambient wind pressure. Eris systems offer insulation that performs during both warm afternoons and cool evenings, keeping rooms stable without added effort.
Noise often travels through air gaps and thin materials. A tightly sealed bi-fold door blocks both sound and thermal exchange. This makes indoor spaces calmer and more controlled without sacrificing ventilation or aesthetics.
When you choose Eris bi-fold doors, you’re choosing more than just a stylish entrance; you’re choosing sustainability, comfort, and peace of mind. With Title 24 accredited U-Factor and Solar Heat Gain Coefficient ratings, our doors set the standard for energy-efficient design without compromising on performance or style.
Elevate your space with Eris bi-fold doors and embrace a brighter, more sustainable future.

FAQs
What makes a bi-fold door energy-efficient?
An energy-efficient bi-fold door minimizes heat transfer and solar gain through insulated frames, low-emissivity glass, and tight sealing. These features help reduce indoor temperature fluctuations and support lower energy use.
Is Title 24 compliance mandatory for all doors in California?
Yes, any new construction or major renovation in California must meet Title 24 energy standards, including U-Factor and SHGC requirements for doors and windows.
What U-Factor is considered compliant under Title 24?
The required U-Factor varies by climate zone, but most zones require a U-Factor of 0.30 or lower for doors to meet Title 24 performance standards.
Can bi-fold doors be both energy-efficient and stylish?
Yes. Modern bi-fold systems like those from Eris are designed to meet strict energy standards without compromising aesthetics, offering both thermal performance and visual appeal.
Do energy-efficient doors help with noise reduction?
In many cases, yes. The same features that insulate against temperature, such as tight seals and layered glazing also reduce sound transmission from outside.
