Why closed cell spray foam [CCSF] is far superior compared to traditional fiberglass & cellulose products

 

  Fiberglass allows air & moisture to pass through it easily – CCSF is superior because it is an impermeable air & moisture (vapor) barrier. CCSF boasts the highest R-value per inch of any insulation on the market. Closed-cell spray foam has an R-value of roughly 6.5-7 per inch. R-value of fiberglass is significantly lower at around 2.2 per inch. In addition, fiberglass insulation loses R-value over time while spray foam insulation maintains its effectiveness. Once the temperature outside falls below freezing, fiberglass loses as much as 50% of its R-value. Closed-cell spray foam is not affected by temperature and moisture like fiber products.

  Fiberglass requires the use of traditional roof and baffle venting to flush out any moisture that travels through the material. In turn, this intensifies the structure’s stack pressure, increasing the flow of air. This hinders efficiency through the loss of conditioned air and also negatively impacts comfort by increasing air infiltration/draftiness. Air that is lost, is replaced by an equal amount from outside. CCSF eliminates the need for ventilation in most cases, reduces the structure’s stack pressure, and retains conditioned air temperature for a long period of time due to its impermeability. This is ideal for those seeking superior comfort & savings.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  Fiberglass provides NO structural benefit. CCSF is rigid and increases the structural strength significantly. Fiberglass breaks down over time as air & moisture pass through it. This can release tiny particulates into the living space air leading to poor, polluted indoor air quality. CCSF once cured is inert and does not break down over time. Fiberglass can be a breeding ground for rodents, insects, and mold. CCSF is a moisture inhibitor and is too rigid to be used by rodents and insects in most cases.
