The
success of rigid polyurethane foams for building thermal insulation
comes from some key properties:
• Excellent thermal insulation got by the lowest available
thermal conductivity
• Lightness
• High mechanical features
• Dimensional stability with high or low temperature
• Inertia to the most common chemical agents
• Best processability permitting stable and durable
combination with almost all the building materials
• Fire reaction suitable to end-use and in conformity
with the most severe Standards in force
• Compatibility with people and environment ensured
by physical and chemical inertia of foams
