SPF Testing – Thermal Insulation

Thermal insulation is one of the key components of a good collector. Thermal insulation usually contains binders or other chemicals that outgas at high temperatures and cause deposits on the cover. With an SPF certificate this can be prevented.


With the SPF certification program for insulation materials in thermal collectors, the outgassing behavior is assessed: The insulation is heated in a controlled manner and caused to outgas. The precipitates are visually assessed and classified. The outgassing of thermal insulations intended for use with anti-reflective treated glass is also evaluated spectroscopically
