Sentence 9.25.2.5.(1)

Intent 1:

To limit the probability that the installation of spray-applied polyurethane will fall significantly below expectations with regard to:

• spray equipment and operating parameters,
• chemicals or storage conditions,
• application procedures (including climatic conditions),
• physical properties (such as density, cohesion and adhesion), and
• substrate type, condition and preparation.

This is to limit the probability of inadequate thermal resistance, which could lead to excessively low temperatures of interior surfaces or within assemblies.

This is to limit the probability of condensation, which could lead to deterioration, which could lead to compromised structural integrity of assemblies acting as environmental separators, which could lead to harm to persons.
