Overview

The oSIST prEN 15599-1:2007 standard, developed under the auspices of CEN Technical Committee CEN/TC 88, specifies detailed requirements for thermal insulation products formed from expanded perlite (EP), used primarily in building equipment and industrial installations. This first part of the standard focuses on bonded and loose-fill expanded perlite products before installation, providing a framework for product characterization, testing, conformity evaluation, and labeling prior to their application.

Expanded perlite is a lightweight granular insulation material produced by heating naturally occurring volcanic rock, resulting in a cellular structure that provides effective thermal insulation over a wide temperature range (approximately 0 °C to +650 °C). This standard applies to three main EP product types:

• Perlite Aggregate (EPA) – untreated loose expanded perlite
• Coated Perlite (EPC) – expanded perlite with surface coatings
• Premixed Perlite (EPM) – expanded perlite combined with binders

The document supports harmonization efforts under the EU Construction Products Directive and facilitates CE marking for these insulation materials within European markets.

Key Topics

• Scope & Applications
  Specifies expanded perlite insulation products used for thermal insulation of building installations and industrial equipment, within the operating temperature range of about 0 °C to 650 °C. It excludes formed shaped products, boards, sound insulation, and applications outside industrial/building technical uses.

• Product Requirements
  Covers essential physical and chemical properties such as:

  • Thermal conductivity (declared thermal resistance)
  • Loose bulk density
  • Particle size distribution
  • Reaction to fire behavior
  • Durability characteristics
  • Maximum and minimum service temperatures
  • Water vapor transmission resistance
  • Crushing resistance
  • Trace water-soluble ions and pH value
  • Limits on organic content (<1%) and harmful substance release

• Testing & Conformity Evaluation
  Defines sampling, conditioning, and testing methodologies to assess and verify product attributes accurately before installation. Provides factory production control guidance and conformity evaluation to meet EU mandates.

• Identification & Labeling
  Establishes requirements for clear marking and labeling to ensure traceability and user awareness of product compliance and characteristics prior to use.

Applications

• Thermal insulation in building equipment systems such as HVAC ductwork, hot water and steam pipes, and mechanical installations.
• Industrial installations requiring high-performance insulation solutions that withstand elevated service temperatures up to +650 °C.
• In-situ formed insulations where expanded perlite is applied directly at installation sites, either as loose-fill or bonded form.
• Suitable for applications where lightweight, fire-resistant, and durable thermal insulation materials are critical to energy efficiency and safety.

Expanded perlite products offer advantages like low density, excellent thermal resistance, and fire retardancy, making them practical for diverse insulation challenges in construction and industrial sectors.

Related Standards

oSIST prEN 15599-1:2007 is part of a series addressing in-situ formed insulation products and interacts with related European and international standards, including:

• EN 14316-1 - Use of expanded perlite in building applications
• prEN ISO 9229 - Definitions of thermal insulation terms
• EN 1097-3 - Determination of loose bulk density for aggregates
• EN 13055-1 & EN 13055-2 - Properties of lightweight aggregates for various construction materials
