Office flooring is the largest horizontal surface in any workspace — every chair movement, footstep, and traffic route happens at floor level.
Carpet tile is the only modular material that simultaneously addresses indoor air quality, reverberation, and design flexibility — yet products installed without certification can become a new source of TVOC (Total Volatile Organic Compounds) emissions.
Why Flooring Determines the Office Environment
Flooring is the largest horizontal surface in an office. Every chair movement, footstep, and circulation route occurs at floor level, and the choice of material directly affects three dimensions: indoor air quality, acoustics, and visual character.
Vinyl tile, laminate, and exposed concrete are typically selected on cost and durability alone. Flooring evaluated on acoustic performance and emission standards as well makes a measurable difference — lower ambient noise, improved indoor air quality, and longer replacement cycles.
Office flooring has four core performance indicators: (1) indoor air quality — TVOC and HCHO (Formaldehyde) emission levels; (2) acoustic performance — impact sound reduction and sound absorption coefficient; (3) durability and maintenance cost; (4) design flexibility.
Eco-label-certified carpet tiles excel on all four counts, and certification ensures that manufacturer claims have been independently verified by a third party.
Korea Eco-Label: Government Certification, Not Self-Promotion
The Eco-Label is an official certification issued by KEITI (Korea Environmental Industry and Technology Institute), an agency under the Ministry of Environment. Products awarded the mark pass third-party testing across the full lifecycle — from raw material sourcing and manufacturing through in-use performance and end-of-life recyclability.
Carpet tiles are evaluated under Eco-Label certification standard EL248. Test items include: (1) total volatile organic compound (TVOC) emission level; (2) formaldehyde emission level; (3) heavy metal content (lead, cadmium, chromium, mercury); (4) manufacturing process wastewater standards; and (5) recyclability.
If any single item exceeds the threshold, the entire product line loses certification eligibility.
The Eco-Label mark carries real weight with corporate procurement teams, ESG reporting requirements, and the G-SEED (Green Standard for Energy and Environmental Design) green building certification.
The same applies to LEED (Leadership in Energy and Environmental Design) credit scoring.
Specifying certified products is increasingly a matter of compliance, not preference.
Importantly, the Eco-Label is not a self-certified marketing claim. Independent laboratory testing, manufacturing site audits, and annual renewal are mandatory. If manufacturing standards slip, the certification is withdrawn — meaning specifying an Eco-Label product is equivalent to specifying a material whose environmental performance is continuously monitored by a government agency.
Why Carpet Tile Has Become the Standard for Office Flooring
Carpet tile has become the standard specification for office flooring in commercial interiors worldwide. The reasons go beyond aesthetics and rest on four quantifiable performance advantages.
Acoustic Performance — Impact Sound Reduction + Reverberation Control
Carpet tile absorbs footstep impact noise (ISO 717-2 ΔLw 25–30 dB) and brings reverberation time (RT60) below 0.6 seconds, reducing the concentration-disrupting factors typical of open-plan spaces. This translates directly to measurable reductions in occupant fatigue.
Modular Replaceability — Lifecycle Cost
Only soiled or worn tiles need replacement, eliminating full re-installation. This reduces waste, re-installation downtime, and delivery lead times, cutting lifecycle cost by 30–40% compared with vinyl tile.
Design Flexibility — Multi-Zone Zoning
A single collection offers hundreds of colours, textures, and patterns. Mixed-tile zoning — differentiating focus work, collaboration, and circulation zones by colour — is a design strategy that only carpet tile can implement efficiently.
Indoor Air Quality — Passive Particulate Filter
Certified carpet tiles capture airborne dust and allergens at floor level, reducing re-suspension into the breathing zone. However, this benefit only holds when the carpet itself has zero TVOC emissions — which is precisely where Eco-Label certification makes the critical difference.
Carpet tile is also 100% compatible with raised-floor systems — a standard requirement in technology-intensive environments. Sub-floor cabling can be accessed without disturbing large areas, and this operational flexibility is a significant factor in the total cost of ownership for offices with extensive IT infrastructure.

ANKER Carpet Tile — Eco-Label Certification No. 34864
ANKER has manufactured carpet tiles in Germany for over 170 years. This longevity reflects consistent product quality and manufacturing standards maintained across generations of commercial projects.
ANKER holds EN 14041 (European textile floor covering standard), EN ISO 9001:2015, GUT label, CE marking, and Cradle to Cradle certification.
In Korea, ANKER carpet tiles have been awarded the Korea Eco-Label (Certification No. 34864) — the result of passing independent laboratory analysis across all mandatory KEITI items. Test values fall substantially below the threshold limits.
TVOC 0.02, formaldehyde 0.006 — both well below the threshold limits. These results reflect ANKER's standard manufacturing quality, not a product engineered specifically to pass certification. All 16 collections have been tested and certified to the same standard.
ANKER's 16 collections span the full range of commercial interiors. Representative collections include PALETTE and QUARTZ for corporate open-plan and executive floors, BLOCK and MIST for contemporary workplace design, and the FluidStop hygiene series for environments with high sanitation requirements such as healthcare and food service. All collections hold Eco-Label certification.

Tornex Tailored Solutions — From Specification to Installation
As the official ANKER carpet tile dealer, Tornex delivers value beyond simple product supply. The value is created through a three-stage process that transforms specifications into finished installations.
Stage 1 · Acoustics-Based Specification Design
We measure and evaluate reverberation time targets (RT60), impact sound isolation ratings (ISO 717-2 ΔLw), and occupancy patterns, then select the appropriate ANKER collection, backing, and pile structure for the specification. Eco-Label certification numbers and test conditions are included in the material schedule.
Stage 2 · Layout Design and Zoning
We design the carpet layout to match the floor plan — including multi-zone colour strategies, curved partition transitions, mixed-colourway patterns, and module cutting drawings. To ensure design intent is preserved through to installation, we deliver the package as drawings, colour samples, and installation guidelines together.
Stage 3 · Installation and Project Management
Site preparation, sub-floor condition inspection, adhesive application (Eco-Label certified EL246 adhesive recommended), tile installation, and post-installation inspection are all managed under a single point of responsibility. After installation, we deliver certification documents, as-built drawings, and a maintenance guide as a digital package.
In a corporate headquarters renovation in Seoul, the specification team selected ANKER carpet tiles across approximately 8,000 m² of open-plan floor space on multiple storeys. The selection drivers were acoustic requirements, aesthetic consistency across departmental zones, and the project team's ESG material reporting obligations.
ANKER's Eco-Label certification provided the sustainability disclosure documentation, and post-installation measurements confirmed impact sound reduction (ΔLw 27 dB) consistent with the product specification.
In a professional services office renewal, the design team applied ANKER's two-tone tile zoning strategy — warm colourways in collaboration areas, calm neutrals in focused-work zones. Tornex's supply chain ensured design intent was faithfully executed on site, and the finished installation reads as a single coherent design.
These projects demonstrate a consistent pattern: in environments where acoustic performance, indoor air quality, design precision, and long-term maintainability are required simultaneously, Eco-Label-certified carpet tile — when properly specified and installed — delivers reliable results on all four dimensions regardless of building type, sector, or project scale.
Q1How does Eco-Label differ from GR / KS certification?
Q2If carpet is certified but adhesive/subfloor emits TVOC, does the cert matter?
Q3If the eco-label expires after install, what happens?
Q4Is carpet tile alone enough to control reverberation in open-plan?
Q5How is removed carpet disposed of?
An eco-label means the material re-passes a government test every single year.
In Summary — Four Obligations, One Specification
Selecting eco-friendly carpet tile for an office ultimately means meeting four obligations within a single specification — indoor air quality (TVOC and HCHO certification), acoustics (ΔLw 25–30 dB + RT60 < 0.6 s), design flexibility (16 collections × multiple colourways), and ESG / G-SEED / LEED reporting.
With the ANKER Eco-Label (No. 34864) and Tornex's three-stage installation process, designers, facilities managers, procurement, and ESG officers can each verify their own requirements from a single specification document.
