Standard for Thermal Insulation - Spray Applied Rigid Polyurethane Foam, MediumDensity, Material - Specification
This Standard provides the requirements and test methods for spray-applied
rigid polyurethane cellular plastics, medium density, used as a thermal
insulation for both building and non-building applications, whether applied on
a building site or in a prefabrication (manufacturing) facility. The material
is also known as foamed in-situ insulation.
The spray-applied rigid polyurethane cellular plastic thermal insulation
shall not be used when the continuous service temperature of the substrate is
outside the range of -60 to +80°C.
The test methods used to determine the material properties provide a means
of comparing different cellular plastic thermal insulations. They are intended
for use in specifications, product evaluations and quality control. They are
not intended to predict end-use product performance.
Spray-applied rigid polyurethane cellular plastic thermal
insulation-medium density must be applied (installed) in accordance with the
manufacturer's instructions and CAN/ULC-S705.2, Thermal Insulation - Spray
Applied Rigid Polyurethane Foam, Medium Density, Application - Specification by
a licensed contractor using a licensed installer for the actual application.
Applications, requirements for applications and limitations of use are included
