Fiberglass Insulation

  1. 1. Fiberglass Insulation<br />By: James Bailey &Danielle Ballard<br />http://www.flickr.com/photos/juniorvelo/3463629589<br />
  2. 2. What is Fiberglass Insulation?<br />Leading insulation material<br />Blanket or loose-fill<br />Used in buildings, pipes, roofs, walls<br />Controls temperature and sound<br />Reduces transmission of moisture<br />Helps resist moisture vapor<br />Yearly business revenue is $8.5 million<br />Expected to grow with renewed growth<br />
  3. 3. Manufacturing Fiberglass Insulation<br />Glass is melted & liquid is spun to create fibers<br />Binder is added to fiberglass to hold it together<br />Most common binder is phenol-formaldehyde<br />Alternative binders with lower VOC are available<br />Alternative binders: Acrylic (JM) and renewable bio-based (Knauf)<br />Minimum of 30% recycled glass<br />
  4. 4. Regulatory VOC Limits<br />No determined standard for formaldehyde in residential settings<br />OSHA and NIOSH have set up occupational limits<br />OSHA sets PEL/TWA at 750 ppb <br />OSHA sets PEL/STEL at 2000 ppb<br />NIOSH sets TWA at 16 ppb<br />
  5. 5. Volatile Organic Compounds (VOCs)<br />Most fiberglass insulation contains VOCs<br />A VOC of major concern is formaldehyde<br />Irritates eyes, nose, throat, and lungs; can be a carcinogen <br />Just one of many VOCs<br />Formaldehyde free brands are available<br />

  7. 7. Manufacturers of Fiberglass Insulation<br />GreenguardIndoor Air Quality Certified<br />Environmental institute that<br /> protects human health<br />Researches product emissions<br />Determines appropriate levels of emissions<br />Certifies products with low emissions<br />Certified companies: CertainTeed, Guardian Fiberglass, Johns Manville, Knauf, Owens Corning<br />
  8. 8. Alternatives to Fiberglass Insulation<br />Cotton batts (denim): Ultra touch, low energy manufacture, no VOCs<br />Mineral wool: 75% post-industrial recycled content<br />Cellulose loose fill: sprayed, settles<br />Sprayed polyurethane foam: expands, high R-value<br />Recycled newspapers: superior insulator <br />Soy-based foam: healthier, benefits of spray foam<br />Rigid foam board: expensive, used at edges of concrete<br />Perlite: light weight, enhances fire ratings, rot resistant<br />http://www.instructables.com/id/istalling-Ultra-touch-recycled-cotton-demin-ins/<br />http://www.flickr.com/photos/kathyastone/3030049468<br />
  9. 9. Do Fumes Get Into Indoor Air?<br />2 types: petroleum & excess binder<br />Petroleum smell is from recently manufactured fiberglass<br />Goes away in a few days<br />Residual binder causes another type of odor<br />Smells fishy or urine-like<br />Dissipates slower than petroleum smell, depends on amount of binder left<br />To speed the removal, ventilate area<br />
