Spray Polyurethane Foam Insulation SPF Nusiance Odor Investigations #IAQS #IAQ

2,981 views

Published on

With the rapid increase in the "Green" movement and the push for more energy efficient homes, spray polyurethane foam SPF insulation is growing substantially. As with most new building products, the industry has had its own set of unique challenges that include the recognized need for training and certification for installers. Along with the recognized need for training are the results of inadequate applicator training, nuisance odors and occupant sensitivity.

These occupant related complaints have led to a rise in SPF insulation investigations by many who have little understanding of SPF insulation and how it can alter the indoor environment even when correctly installed.

  4. 4. 10/20/2013 www.FloridaIAQ.com Slide 4 OF 8510/20/2013 www.FloridaIAQ.com Slide 4 OF 88 Introduction • Along with the recognized need for training are the direct results of inadequate applicator training: – nuisance odors and occupant sensitivity. • These occupant related complaints have led to a rise in SPF insulation investigations by many who have little understanding of SPF insulation and how it can alter the indoor environment even when correctly installed.
  5. 5. 10/20/2013 www.FloridaIAQ.com Slide 5 OF 85 SPF ODOR INVESTIGATIONS When it comes to the investigation of occupant complaints associated with SPF you’ll need more than air samples
  6. 6. 10/20/2013 www.FloridaIAQ.com Slide 6 OF 8510/20/2013 www.FloridaIAQ.com Slide 6 OF 88 SPF Odor Investigations • When it comes to the investigation of occupant complaint or the nuisance odors associated with the application of SPF insulation, I’ve found that most of the investigations typically involve little more than varied attempts at trying to chemically associate the occupant complaint odor with the off-gassing of SPF.
  7. 7. 10/20/2013 www.FloridaIAQ.com Slide 7 OF 8510/20/2013 www.FloridaIAQ.com Slide 7 OF 88 SPF Odor Investigations • I’ve assessed a dozen or so product lines both closed and open cell for manufactures, builders, homeowners, and applicators. • The properties ranged from universities, community centers, offices, homes, both new construction and retrofit applications.
  8. 8. 10/20/2013 www.FloridaIAQ.com Slide 8 OF 8510/20/2013 www.FloridaIAQ.com Slide 8 OF 88 SPF Odor Investigations • The investigation of SPF occupant complaints must begin with the identification of the SPF installed and then • The physical inspection of the installed SPF – The physical inspection of the applied SPF is to establish if the applied SPF is installed correctly or misapplied and the possible cause and origin of the occupant complaint • The investigation must begin with the physical inspection of the SPF

  10. 10. 10/20/2013 www.FloridaIAQ.com Slide 10 OF 8510/20/2013 www.FloridaIAQ.com Slide 10 OF 88 SPF Inspection Goal • Has the applicator met the Project specifications and • The manufacturer’s installation requirements? – Is the SPF Installed Correctly? A potential case for product failure or defect that may be impacting the occupants must begin with the establishment of correct product installation and performance.

  75. 75. 10/20/2013 www.FloridaIAQ.com Slide 75 OF 85 CATEGORIES OF MISAPPLIED SPF A Method to the Madness
  76. 76. 10/20/2013 www.FloridaIAQ.com Slide 76 OF 8510/20/2013 www.FloridaIAQ.com Slide 76 OF 88 Categories of Misapplied SPF • In my experience, SPF investigations can be categorized in three distinct categories. • By using these three assessment categories, I have had great success in identifying the catalyst of SPF associated odors and complaints.
  77. 77. 10/20/2013 www.FloridaIAQ.com Slide 77 OF 85 CATEGORY 1 MISAPPLIED SPF The SPF inspector must remember, that while the SPF insulation may be the issue, unless you can say there are no other issues within the home, you have not completed your investigation you’ve just begun.
  78. 78. 10/20/2013 www.FloridaIAQ.com Slide 78 OF 8510/20/2013 www.FloridaIAQ.com Slide 78 OF 88 Category 1 Category 1 Includes: • Improper ventilation during the application, • Incomplete application, • Off ratio application, • Over-spray
  79. 79. 10/20/2013 www.FloridaIAQ.com Slide 79 OF 8510/20/2013 www.FloridaIAQ.com Slide 79 OF 88 Category 1 • Nuisance odors that are directly associated with incorrectly applied SPFI can be addressed by either correcting the areas of misapplied foam or by removing and re-insulating the areas.
  80. 80. 10/20/2013 www.FloridaIAQ.com Slide 80 OF 85 CATEGORY 2 PRE-EXISTING OR RECENTLY INTRODUCED CONTRIBUTORS You haven't completed your investigation you’ve just begun
  81. 81. 10/20/2013 www.FloridaIAQ.com Slide 81 OF 8510/20/2013 www.FloridaIAQ.com Slide 81 OF 88 Category 2 • This category cannot be stress enough to the professionals that are investigating SPFI. • This category runs the gamut and can include some rather odd contributors to occupant discomfort and nuisance odors that become much more concentrated when the SPFI is installed.
  82. 82. 10/20/2013 www.FloridaIAQ.com Slide 82 OF 8510/20/2013 www.FloridaIAQ.com Slide 82 OF 88 Category 2 • These include the: – HVAC system, – air exchange rate, – storage of materials in the now sealed space, – insect and or rodent activity, – routine pest control applications, – the previous insulation condition and material, – proper ducting of kitchen and bath fans. • The possibilities are endless
  83. 83. 10/20/2013 www.FloridaIAQ.com Slide 83 OF 8510/20/2013 www.FloridaIAQ.com Slide 83 OF 88 Category 2 • The SPF Inspector must ask relevant questions such as; – “What is the condition of the new semi-conditioned space?” – “What have the occupants been sealed in with?” – “How is the air exchange rate being met?” – “How is the semi-conditioned space actually being semi-conditioned?”
  84. 84. 10/20/2013 www.FloridaIAQ.com Slide 84 OF 85 CATEGORY 3 SENSITIZATION DUE TO EXPOSURE A bell cant be un-rung
  85. 85. 10/20/2013 www.FloridaIAQ.com Slide 85 OF 8510/20/2013 www.FloridaIAQ.com Slide 85 OF 88 • This category is unique in that any attempt at reducing the occupant’s exposure to the SPF insulation that they are now sensitized to may not be of any relief. • I have had no luck in providing sensitized occupants relief from the home they are now sensitive to.
  86. 86. 10/20/2013 www.FloridaIAQ.com Slide 86 OF 8510/20/2013 www.FloridaIAQ.com Slide 86 OF 88 • I have been involved in everything from the introduction of outdoor air through a pre-filter and dehumidifier to control the temperature, humidity, particles, path, and pressure to full removal of the SPF insulation. Unfortunately that bell can’t be un-rung.
  87. 87. 10/20/2013 www.FloridaIAQ.com Slide 87 OF 85 SUMMARY Spray Polyurethane Foam SPF Insulation Nuisance Odor Investigations “It’s Not Aways the Foam”
  88. 88. 10/20/2013 www.FloridaIAQ.com Slide 88 OF 8510/20/2013 www.FloridaIAQ.com Slide 88 OF 88 Summary • By expanding my approach to SPF investigations, I have found that not all SPF insulation complaints are a result of misapplied SPF. • This has led to may believing that I’m simply ignoring the issue of misapplied SPF or the concerns with occupant exposure to the application of SPF insulation.
  89. 89. 10/20/2013 www.FloridaIAQ.com Slide 89 OF 8510/20/2013 www.FloridaIAQ.com Slide 89 OF 88 Summary • That could not be further from the truth. Of the three categories discussed in this presentation, two directly address the areas I’m often accused of either avoiding or ignoring. • It’s the second category that seems to raise concern with other IEP’s investigating SPF Insulation nuisance odors and complaints.
  90. 90. 10/20/2013 www.FloridaIAQ.com Slide 90 OF 8510/20/2013 www.FloridaIAQ.com Slide 90 OF 88 Summary • To ensure SPF is applied correctly and avoid occupant exposure during application, we strongly encourage all SPF applicators participate in the SPFA's The Spray Polyurethane Foam Professional Certification Program (“SPFA PCP”)
