GreenFLEX established the Oregon field history. HDBS redeveloped and improved that concrete-SIP lineage and now manufactures the current product as VallDURA™. The GreenFLEX name remains where historical projects, test reports, and patents require it; current product identity, evaluated configuration, labeling, and certification are governed by Twining Evaluation Report TCI-0001.
If you’re a homeowner, a custom-home builder, or a commercial contractor — and you’re looking for a more integrated wall system with documented third-party evaluation — VallDURA™ was built for that conversation.
A durable, high-performance wall approach built around continuous EPS insulation and reinforced cementitious facings — supported by third-party evaluated structural, fire, water-penetration, and durability data.
Integrate structure, continuous insulation, and reinforced cementitious facings in a factory-built panel. Fewer separately installed wall components can simplify sequencing and help protect schedule and margin.
Repeatable factory-built wall panels with documented design values, traceability, and third-party surveillance — fewer field variables and a clearer technical submittal path.
VallDURA™ combines a 6-inch EPS core, reinforced cementitious facings, and integral cold-formed steel top and bottom tracks in the configuration evaluated under TCI-0001. Final project finishes, weather-barrier assemblies, connections, and structural design follow approved documents, manufacturer instructions, and AHJ requirements.
VallDURA™ uses a continuous EPS core through the panel field, reducing the stud-bridge effect common to conventional framed walls. The current certified configuration is governed by Twining Evaluation Report TCI-0001.
Fewer separately installed wall components can mean fewer field steps and a more controlled assembly. Actual labor, schedule, envelope performance, and project cost depend on design, sealing, finishes, site conditions, and installation.
Certified structural and fire-performance values come from TCI-0001. Thermal R-values shown here are manufacturer / legacy data and are identified separately.
R-18 / R-26 / R-31 are manufacturer / GreenFLEX legacy thermal values referenced in the technical briefing; they are not stated in TCI-0001. The current TCI-0001 evaluated configuration uses a 6-inch EPS core with approximately .375-inch facings on both sides. Project energy performance must be confirmed for the approved assembly.
VallDURA™ Building Method
A short introduction for owners, builders, and partners. Click through for the full plain-language page explaining how HDBS post-frame construction projects can incorporate VallDURA™ panels.
For Central Oregon builders and owners, the method is practical: an engineered post-supported structure combined with factory-built VallDURA™ wall panels, continuous EPS insulation, and project-specific connections and finishes.
Twining Consulting Inc. issued Evaluation Report TCI-0001 for VallDURA™ Concrete Structural Insulated Panels under its ISO/IEC 17065 product-certification procedures. The report was first published in August 2026 and the product remains subject to ongoing surveillance under ISO/IEC 17020.
Date First Published: August 2026 · Renewal Due By: February 2027 · Official report received by HDBS August 28, 2026.
TCI-0001 evaluates VallDURA™ for the stated structural, fire, water-penetration, durability, and weather-protection properties. Project-specific use remains subject to the locally adopted code, approved construction documents, the registered design professional, and the authority having jurisdiction.

Conceptual renderings shown for illustrative purposes only. Final design, materials, dimensions, and details may vary.
Three modern HDBS home concepts built for the Central Oregon high desert — distinct palettes and a shared clean shed-roof design. VallDURA™ CSIP walls can be evaluated for these concepts; final structural, weather-protection, cladding, and finish assemblies remain project-specific.
Compact, bright, and efficient — a perfect ADU or starter home.
Bold and contemporary — two bedrooms with a generous shared core.
The flagship — three bedrooms, a home office, and a primary suite.

VallDURA™ is designed around an integrated, durable wall system: continuous EPS insulation, reinforced cementitious facings, and factory-controlled production. The value case is fewer field-installed components, durable materials, and performance that can be reviewed against documented data.
TCI-0001 reviews durability and environmental evidence for the reinforced cementitious facings, including weathering, freeze-thaw, salt-spray, and water-penetration testing. Final service life depends on project design, exposure, finishes, and maintenance.
The EPS core runs continuously through the panel field, reducing conventional stud thermal bridging. Whole-building energy performance still depends on joints, sealing, openings, roof/floor assemblies, HVAC design, and installation.
Reinforced cementitious facings and an EPS core avoid many moisture-decay mechanisms associated with wood-based sheathings. Final maintenance requirements depend on the approved exterior/interior finish systems and exposure conditions.
The GreenFLEX legacy product lineage has a 300+ structure field history, including homes, park models, commercial buildings, agricultural buildings, and workforce housing in extreme climates. VallDURA™ is the current HDBS product identity and is separately governed by TCI-0001.
Our HDBS design team works in CAD and SketchUp to help visualize and plan your build before panels are ordered. VallDURA™ wall-system requirements, project-specific structural design, finishes, and code conditions are coordinated into the design path from the start.
Structural engineering support for HDBS / VallDURA™ projects, including foundation, framing, load-path, wind, seismic, and diaphragm design coordination.
