Performance and aptitude assessment of building insulation products

LNE proposes an entire line of tests that enable characterizing building insulation products, such as insulating materials and insulating glass panes. This service pertains to regulatory testing within the scope of EC marking applications (components covered by the RPC building industry products regulation) or else specific client requests.

Services proposed

Among the proposed series of characterizations:

- Insulation materials:

  • Thermal performance tests: measurement of the thermal resistance of insulation materials,
  • Mechanical performance tests: tests of tension, compression, shear, water resistance, etc.,
  • Fire behavior tests: Euroclass tests (single burning item (SBI), solar panel, higher calorific value, ignitability, LEPIR protocol, etc.),

- Insulating glass panes:

  • Measurement of the gas filling rate by means of a destructive or non-destructive method,
  • Dew point measurement in the laboratory or in the field,
  • Resistance to humidity penetration, measurement of the humidity penetration index, measurement of humidity recovery on the dehydrating agent,
  • Characterization of glass pane components (dehydrating agent, spacers, mastic materials, crosspieces),
  • Customized tests to identify the causes of a loss of glass pane performance (pressure drop, break, humidity penetration, etc.).

Resources available

To perform these services, we have at our disposal the following equipment:
