Certifications & standards

Tested. Approved. Verified.

Every certification references a specific body, standard and scope. Wording must remain product- and assembly-specific — never generalised beyond the stated test scope.

CE Marking
CE Certificate of Conformity
Certificate-of-conformity-CE · Isotex ITC
CE marking under the Construction Products Regulation (CPR). Confirms products meet the essential requirements for marketing and use across Europe.
Conformity · quality
BBA
British Board of Agrément
BBA Certificate — UK Building Regulations
BBA certification confirms compliance with the relevant requirements of the UK Building Regulations and supports use in professional UK specifications.
UK compliance
ETA
European Technical Assessment
ETA-08/0023 · 2025 edition
European Technical Assessment provides a basis for CE marking for construction products where no harmonised standard exists. Documents available in the source register.
Conformity · CE basis
CSTB
REI 120 Fire Resistance · Wall Systems
CSTB fire resistance of blocks REI 120 certification
Wall and block systems may be referenced as REI 120 where the page makes clear this is wall/block context. Tested by CSTB (Centre Scientifique et Technique du Bâtiment).
Fire · wall systems
CSI
REI 240 Fire Resistance · Floor Systems
CSI fire resistance of floors REI 240 certification
Floor systems may be referenced as REI 240 where the page makes clear this is floor-system context. The higher rating reflects the more robust slab configuration.
Fire · floor systems
Environdec
Environmental Product Declaration
EPD S-P-01472 (blocks) · S-P-01291 (floors) · S-P-01290 (acoustic)
Three EPDs registered with Environdec covering wood-cement blocks, floor slabs and acoustic elements. Supports specification under BREEAM, LEED and Part Z frameworks.
Sustainability · EPD
ANIT
Acoustic Insulation Certification
Acoustic Insulation Technical File · ANIT
Certified acoustic performance data. Values are product- and assembly-specific and must not be generalised. The acoustic register contains 33 verified entries across product configurations.
Acoustic
BMBcert
Neopor® Graphite EPS Certification
Neopor® BASF BMBcert — biomass balanced
The Neopor® graphite-enhanced EPS insulation used within the HDIII system carries BASF BMBcert certification for biomass-balanced production. Referenced as Neopor® BMBcert only.
Material · EPS
EC8
Seismic Design Support
Catalogo Sisma Isotex · EC8 design reference
Seismic design support documentation is available in the supplied source set. Reference EC8 design requirements for the relevant application and project location when specifying.
Seismic · structural
Wording discipline: All performance values shown are product- and assembly-specific and are sourced directly from Isotex technical documentation. Do not use absolute wording (fireproof, earthquake-proof, guaranteed). All claims must be verified against the specific certificate or test report before publication.

Published performance values and certification references are product- and assembly-specific and are based on supplied Isotex technical documentation. Values must be verified against the specific certificate or test report before use in any specification. Final product selection, structural design, fire strategy, acoustic design and compliance checks must be confirmed by the appointed project professionals and relevant authorities having jurisdiction.
