Yes. They fit the same tracks and fixings used for steel studs. No special tools or training required.
Yes. Use standard chop saws or drills. Wear PPE as the material produces a fibrous dust similar to MDF when cut.
Yes. Holes can be drilled for services following standard good practice (20mm centre-drilled and not oversized).
Yes. Similar to metal or timber. For very heavy loads, backing or reinforcement is recommended.
Standard profile is 70mm × 2.5m, with more size options in development. To extend the length, use a metal splice. We have tested and built walls with splices, up to 4.6m high.
Yes. BioStud wall systems have been independently tested by BRE and achieved EI60 and EI120 fire classifications when installed as part of the tested wall assemblies.
The certified fire-rated wall systems were tested using 15 mm British Gypsum Fireline fire-rated plasterboard. Allowing specifiers to replicate the tested performance using commonly available UK materials.
Yes, when installed as part of the tested system. Detailed performance reports are available for project documentation.
Yes. Independent acoustic testing shows BioStud partitions provide approximately 1–2 dB improvement in sound insulation compared with equivalent steel stud wall systems, due to the composite material’s natural vibration-damping properties.
Tested BioStud partition assemblies achieved Rw 52–55 dB, depending on the wall build-up, which is within or above the performance range typically achieved by comparable steel stud partitions. More info on our product page.
Absolutely. They perform best with high-density mineral wool or acoustic batts between studs and standard or sound insulating plasterboard systems.
No. They are designed for internal partitions, similar to light-gauge steel studs.
Typical height is 2.5m per stud, with options for greater height depending on wall build-up and design.
They flex and recover gradually rather than buckling, providing excellent stability and ductile failure behavior.
No. The hemp fibres are sealed within a moisture-resistant composite.
Yes, in typical indoor environments. For high-humidity zones, use appropriate plasterboard and ensure the wall cavity stays dry.
Yes. Offcuts and recovered material can be processed into new composites. Circular-use and take-back programs are in development.
Manufactured in the UK using UK and EU-grown hemp.
Batch production currently runs 8-10 weeks depending on volume.
Yes. UK expansion and early-stage US production partnerships are planned.
Yes. BioTwin actively partners on pilots and case studies with technical support. Please get in touch if you have a project in mind.
Currently higher, but whole-life carbon benefits and scaling effects are expected to bring costs toward parity with steel.
BioStud systems have undergone independent fire classification testing (EI60 and EI120), acoustic performance testing, structural/lateral load testing, thermal testing, and Life Cycle Assessment studies conducted by accredited bodies including BRE Global. Please get in touch to see the reports.
Euroclass, UKCA, EPD and future warranty/insurance pathway certification.
