Question: How does Polyurethane Foam work?

Answer: Urethanes are plastics that have gas-filled bubbles that make them light weight and a good insulating material.

Question: What is the difference between open-cell and closed-cell polyurethane foams?

Answer: These two types of polyurethane foams have different R-values, permeability, strength, and costs. Click here for more information

Question: What is the difference between CFC, HCFC and HFC blowing agents in polyurethane foams?

Answer: These "Flouro-carbons" have different amounts of chlorine or are designed to prevent chlorine release into the atmosphere.

Question: Do urethanes "outgas" and are they toxic?

Answer: Urethanes are non-toxic and only require protection for our operators during installations, but the finished product is completely safe and has no formaldehydes.

Question: Are urethanes good for sound insulation?

Answer: Open-cell urethanes are better than closed-cell foams for reducing air-borne sound. Both are good at sealing holes that can let sound through wall or ceiling penetrations. Structure-borne sound CANNOT be controlled with low-density infill materials such as foam or sealants.

Question: What sort of paint should I use for covering polyurethane foams & sealants?

Answer: Typically, spray-applied polyurethane foam is covered by interior or exterior wall coverings or ceiling or roofing details. That said, on occasion it is left exposed and the concern really is only that of ultra-violet light that will degrade the exposed foam over time. In exterior applications, a paint will not suffice, rather a protective coating should be used.
