Spray Foam Insulation

There are multiple variations of the ingredients used in SPI, but the key ingredients are the same. These are two- part systems: one part is an isocyanate (Part A) and t he other part is a mix of polyols, flame-retardants, blowing agents, and other additives (Part B). Foam insulation installers follow the same basic steps that occur in industrial polyurethane factories, but in a far more confined space, combining Parts A and B in peoples’ attics.

During the application process, there are far too many variables at stake that undertrained and untrained applicators simply cannot overcome.  For example: 1) if the mix is off ratio, the result can be chemicals that fail to properly cure; 2) if the foam is slightly under processed, the foam fails to properly cure; 3) if the spray foam is applied in greater than a 2-inch pass, or by applying a second pass over the first without allowing the first pass to properly cure.

High exposure to SPF, including vapors, aerosols and dust during and after installation can cause asthma, lung damage, neurological problems, other respiratory and breathing problems, and skin and eye irritation.  Once sensitized, people have found it virtually impossible to continue residing in the home with SPF, and removal of the product has been extremely difficult or can make the matter worse because of the particularization that can occur during the process.

Spray Foam Dangers

There are so many variables (temperature, mixture, humidity, proper ventilation, proper application, clean-working equipment etc.) involved in the spraying and manufacturing of spray foam insulation and, therefore, some industry experts beleive that this product is not safe for use inside residential homes.
