GaiaPanel™ Hempcrete / Hemp-Lime Wall Panels
Panelized hemp-lime construction designed to combine bio-based wall materials with a faster, repeatable wall-system format.

What Is GaiaPanel™?
GaiaPanel™ is Mr Hemp House®'s panelized hempcrete / hemp-lime building system, designed to bring bio-based wall construction into a faster, prefabricated format. It uses the same hemp hurd and mineral lime material family as GaiaCrete™ hemp-lime building material, assembled into wall sections rather than placed loose on site.
For a homeowner, the practical difference is schedule and predictability: more of the wall is built in a controlled environment, and less of it depends on weather and on-site drying conditions.
Panelized Hemp-Lime Construction and the Wall Assembly
A panel pairs framing with hemp-lime infill filling the cavity, so the wall arrives as one coordinated component. On site the panels are set, joined, and then finished with vapor-open plasters or claddings appropriate to the climate and design.
Panel configuration, framing members, connections, and finishes are engineered per project. Mr Hemp House® does not publish generic load ratings, span tables, panel weights, or fastening schedules.
Why Panelization Matters
Schedule
Wall fabrication happens in parallel with site work instead of after it.
Consistency
Mixing and placement happen under controlled conditions rather than in variable weather.
Repeatability
Repeated plans and multi-unit projects benefit most from a standardized wall component.
Additions and Existing Construction
Panels suit additions, rebuilt walls, and sections where new framing is going up anyway. Where an existing wall stays in place, GaiaBloc™ hemp-lime building blocks or a cast application is usually the better fit. See retrofit and rehab for how existing-home projects are scoped.
New Construction
Panelization is strongest on new builds with defined plans — including hempcrete house plans and healthy new-home designs — where wall sections repeat and the schedule rewards off-site fabrication.

Building-Science Characteristics of Hemp-Lime
These characteristics describe hemp-lime construction as a category. Product-specific and assembly-specific performance is governed by current technical documentation.
Vapor permeability & moisture buffering
Hemp-lime materials can adsorb and release moisture as indoor conditions change, helping moderate short-term humidity swings when incorporated into a properly designed vapor-open assembly.
Mold-resistant characteristics
The high-alkalinity mineral composition of hemp-lime is inhospitable to fungal growth, and the material is vapor-permeable rather than moisture-trapping. Actual mold risk depends on moisture exposure, assembly design, workmanship, bulk-water management, ventilation, and maintenance.
Fire performance
Hemp-lime materials are known for favorable fire-performance characteristics; product- and assembly-specific performance is governed by applicable technical documentation. A Class A flame spread rating (ASTM E84) has been documented for the tested GaiaCrete™ material sample and is not translated here into an hourly fire-resistance rating.
Acoustic characteristics
Hemp-lime's porous structure can help dampen sound and contribute to quieter wall assemblies. Exact acoustic performance depends on wall thickness, finishes, framing, and complete assembly design.
Thermal characteristics
Hemp-lime contributes both insulation and thermal mass to the wall assembly. Thermal performance varies by formulation, density, thickness, moisture content, finishes, and complete wall assembly.
Biogenic carbon storage
Hemp absorbs atmospheric carbon while growing, and hemp-based materials can retain that biogenic carbon in the building. Lime binders also carbonate during curing. Product-specific lifecycle figures are not published as a single number.
Pest considerations
The mineral-rich hemp-lime matrix is generally less attractive as a food source than untreated wood-based materials. Pest performance depends on assembly details, site conditions, and construction.
Long-life assemblies
Published hemp-lime lifecycle research has cited expected service-life assumptions exceeding 100 years for properly designed, constructed, protected, and maintained wall assemblies. This is category-level hemp-lime research, not a Gaia™ product warranty.
The 2024 IRC includes Appendix BL for hemp-lime construction. Local code adoption, engineering, design, product documentation, and authority-having-jurisdiction requirements govern each project.
Technical Information
Technical specifications are being finalized. Contact Mr Hemp House® for current project documentation and product availability.
Panel dimensions, weights, R-values, acoustic ratings, load and span capacities, fire-resistance ratings, and fastening schedules are not published for GaiaPanel™. Documented GaiaCrete™ material test results are not automatically transferred to the panel product or to any specific assembly.
GaiaPanel™ vs Conventional Wall Systems
Conventional framed walls rely on cavity insulation products such as fiberglass batts or spray foam. A hemp-lime panel fills the cavity with a vapor-permeable mineral-and-plant matrix instead, changing how the wall handles moisture and how it is finished. Compare the material approaches in GaiaCrete™ vs spray foam and GaiaCrete™ vs fiberglass.
Comparing the Gaia™ Building Systems Formats
All four formats use hempcrete / hemp-lime construction principles. The difference is how the material reaches the wall.
| Feature | GaiaCrete™ | GaiaBloc™ | GaiaPanel™ | GaiaCast™ |
|---|---|---|---|---|
| Format | Hemp-lime material (sprayed or poured) | Pre-formed block | Panelized wall system | Cast-in-place infill |
| Primary application | Wall, attic, and envelope applications | Wall infill and retrofit build-out | Repeatable wall assemblies | Monolithic framed-wall infill |
| Installation approach | Trained crew, project-specific method | Stacked and fitted by hand | Fabricated off-site, set on-site | Formed and cast in place |
| Existing homes | Project-dependent | Often a good fit where access is limited | Best suited to additions and rebuilt walls | Suitable where framing is opened up |
| New construction | Yes, with a designed assembly | Yes | Yes — schedule-driven projects | Yes — continuous wall assemblies |
| Prefabrication level | None — mixed and applied on-site | Component-level | Highest | None — formed on-site |
| Wall integration | Around a structural frame | Fitted within or against framing | Framing and infill delivered together | Continuous infill around framing |
| Best project fit | Custom hemp-lime applications | Retrofits and phased work | Repeatable plans and tight schedules | Seamless, monolithic wall design |
| Technical documentation | Available — see technical resources | In progress — request current documentation | In progress — request current documentation | In progress — request current documentation |
Final product selection depends on project design, engineering, code requirements, climate, availability, and installation method.
For Builders, Architects, and Remodelers
Panel projects need earlier design coordination than site-applied work: wall sections, openings, connections, tolerances, lifting, and delivery all get resolved before fabrication. Bring drawings to the consultation and we will review product selection, documentation needs, and logistics with you.
Technical Documentation & Research
Mr Hemp House® separates evidence into levels so builders, designers, and homeowners can see exactly what a given statement is based on.
- Product-specific testing — laboratory results for that exact Gaia™ product, where available.
- Assembly-specific testing — results for a tested wall, panel, or installation assembly.
- Hemp-lime category research — published findings that apply to hemp-lime construction generally, not to a specific Gaia™ product.
- Manufacturer / internal documentation — technical documents produced by Mr Hemp House® and identified as such.
Category-level hempcrete research does not by itself demonstrate GaiaBloc™, GaiaPanel™, or GaiaCast™ performance. Review the current documentation set on technical data & resources.
