Thermal Conductivity Measurements for Building and Insulating Materials

NIST's database contains over 2000 measurements of thermal transmission properties. Data was gathered using a standardized 200-mm square guarded-hot-plate apparatus, primarily at 24° C. It covers materials like concrete, fiberboard, plastics, and thermal insulation.

Use Cases

• Analyze thermal conductivity variations across material categories like concrete, fiberboard, and plastics using over 2000 measurements.
• Model heat transmission properties for building applications using data from the standardized guarded-hot-plate test method.
• Compare material performance within the temperature range corresponding to most building applications, noting the concentration of measurements at 24° C.

Strengths

• Over 2000 individual measurements provide a substantial basis for analysis.
• Data collected using a standardized and accurate guarded-hot-plate apparatus, as recognized by ASTM and ISO.
• Covers several analytically relevant material categories including concrete, fiberboard, plastics, thermal insulation, and rubber.

Limitations

• Data format is HTML, which is not ideal for direct programmatic analysis and requires parsing.
• The majority of measurements were conducted at a single temperature (24° C), limiting analysis of property variation across a wider temperature spectrum.
• Specific column names and data structure are not provided, complicating initial data understanding.
