The 5 essential criteria for proper Fine Art Storage

The value of fine art extends far beyond its market price—it represents cultural heritage, emotional significance, and often a long-term strategic asset. According to the Getty Conservation Institute and the Canadian Conservation Institute, most deterioration affecting artworks originates from environmental factors, particularly fluctuations in temperature and humidity. ICOM-CC also highlights that temperature stability is essential to reducing mechanical and chemical risks.

Ensuring the professional preservation of paintings, sculptures, and photographic works means protecting their longevity and long-term value. Here are the five essential criteria for museum-grade Fine Art Storage.

1. A Controlled climate environment

Temperature and humidity: achieving the right balance

A stable temperature between 20°C and 22°C and a relative humidity of 50% to 60% represent the museum-grade standards recommended by the Canadian Conservation Institute (2024).

Any fluctuation may lead to:

structural deformation,
cracking,
mold development.

Fortius applies these standards across its Luxembourg secure facilities, equipped with connected sensors and automatic alerts.

Stability: the golden rule

Sudden variations—more than the absolute levels themselves—cause most forms of damage. Stability is therefore the foundation of successful fine art preservation.

2. Robust physical and digital security

Multi-layered security

A secure fine art storage facility must combine:

24/7 video surveillance,
biometric access control,
inert-gas fire suppression systems,
timestamped digital traceability.

Protected data and encrypted inventories

At Fortius, each item is recorded in an encrypted registry (using AES-256 standards), ensuring absolute confidentiality—a key factor for collectors, institutions, and family offices.

3. Certified Human Expertise

Specialized skills and knowledge

Professional fine art preservation relies on expert teams. Conservators, fine art logisticians, and trained personnel certified to ICOM and ISO 11799 standards supervise each handling operation.

Handling and packing

Use of acid-free, inert materials,
Custom packaging adapted to each medium (canvas, marble, bronze, photography),
Dedicated areas for unpacking, inspection, or restoration.

Qualified teams prevent up to 50% of avoidable damage. Discover Fortius’ Fine Art Storage solutions.

4. Certified and Fully Auditable Infrastructure

Certification and traceability

Choose facilities compliant with internationally recognized standards:

ISO 11799 — archival and fine art storage requirements,
ICCROM / ICOM-CC — conservation and climate recommendations,
AAM (American Alliance of Museums)— museum best practices.

Auditability and insurance compatibility

A high-end facility such as Fortius Luxembourg provides timestamped climate reports and complete traceability—elements required by specialized insurers.

5. Tailored Services and a Strategic Location

Complementary services

A premium provider goes beyond storage alone:

secure fine art transport,
tailored insurance,
customs and fiscal assistance (including freeport regimes),
private access by appointment.
