FIBERGLASS INSULATION IDENTIFICATION - CONTENTS: Characteristics of fiberglass batts or chopped fiberglass used for building insulation.
This article illustrates and describes common fiberglass insulation materials used in buildings and in building HVAC systems. Yellow Fiberglass Insulation: most fiberglass insulation manufacturers other than the ones listed below produce yellow fiberglass insulation.
Pink Fiberglass Insulation: Owens Corning Pink Fiberglass (R) is a registered trademark for their product line. White Fiberglass Insulation: John Mansville produces white insulation including their ComfortTherm(R) encapsulated batts. Black Fiberglass Insulation?: No black fiberglass insulation product has turned up in any of our research.
Dust and dirt may be deposited on fiberglass as air (containing house dust or other debris) moves past fiberglass at air leaks. Black-looking mold may grow on fiberglass that has become dirty and wet, or it may be found more often on the kraft paper attached to fiberglass if that material has been wet - don't blame the fiberglass, blame building leaks on this problem. Fiberglass Insulation is a glass fiber product and does not normally contain asbestos, though it can become contaminated by rodents, insects, or mold, and especially if damaged, disturbed, and exposed to a living space, it can become a source of problem particles, as we discuss at FIBERGLASS HAZARDS.
Laboratory photos of fiberglass can often assist in determining where fiberglass fragments and debris are originating.
The microscope lets us identify the color of resin binders which may enable us to match the colors in fiberglass dust to the colors and binders of samples taken from known fiberglass insulation reservoirs in the building. Furthermore, proper lab procedure and use of mountants with an appropriate refractive index to see glass fragments is critical as otherwise such particles may simply be invisible when viewed using conventional slide preparation methods. Some research argues that fiberglass particles are larger than and less dangerous than asbestos. Following a discussion of the body of knowledge, the expert panel reviewed the RoC listing criteria and made its recommendation.

I want to use fiberglass batts in the beam space between my basement and first floor with the paper backing on the upper floor side. Fiberglass is basically glass - spun into fibers, bound with a resin and sometimes backed on one side with foil or paper.

The Illustrated Home illustrates construction details and building components, a reference for owners & inspectors. This article discusses the properties of various building insulation materials: fiberglass insulation, expanded polystyrene insulation, foil-faced polyisocyanurate insulation, and extruded polystyrene. This article explains the insulating properties and relative costs of common building insulating materials including fiberglass insulation, expanded polystyrene insulation, foil-faced polyisocyanurate insulation, and extruded polystyrene.
The insulation figure of merit, "cost of insulation per square foot R-value, is explained as a means of comparing insulating materials. For superinsulated buildings the article concludes that a double-stud wall with fiberglass batts provided the greatest insulating value per dollar.
Our photograph (left) shows an insulation retrofit in a crawl space where icynene foam spray was applied to the crawl space wall and between the floor joists overhead. The article also discusses the question of air permeability of fiberglass insulation and its impact on the actual insulating value of the material compared with impermeable (to air) foam insulation products. Claims (perhaps by competitors) that EPS absorbs water are dismissed as nonsense - the material is used to float docks.
Problems reported with use of polystyrene as non-structural sheathing where horizontal wood siding is installed included loose clapboards, cupping or cracked clapboards, and nail pulling due to thermal movement of the foam. The wood problems are attributed to the tendency of these relatively impervious insulations to aggravate thermal and moisture cycling in the siding, since they soak up little heat and moisture themselves. Aerogel has an R-value of about R-10 per inch, is 99% air and insulates up to 37 times higher R-value than fiberglass.

Barrier Ultra-R super high-R building panels, produced by Glacier Bay, use Aerogel and are rated up to R-30 per inch, or in Barrier Ultra-r™ panels, R-50 per inch.
The product is used in marine refrigerators, but in the future may be available as a residential construction product. Eco-Panel polyurethane foam core structural insulated panels (SIPs) are produced by Eco-Panels Corporation. The company offers a super-insulated 8.5-inch thick structural insulated panel and also produces roof panels.
Hightherm R-24, Supertherm R30, and Superthermal R60 wall panels are produced by Supertherm. Low-E Housewrap Insulation™, is a patented insulation consisting of a closed micro-cell foam core that is heat laminated to foil or polyethylene facings. Precision Panel R28 (R-4 to R-7 per inch) Laminated EPS foam core Structural Insulating Panels (SIPs) are produced by Precision Panel Co. Super Therm® insulating ceramic coatings produced by Superior Solar Barrier, are used on buildings as well as freezers and refrigerators, intended as an impenetrable exterior coating. The foam core is sandwiched between a choice of exterior faces including aluminum foil, tri-plex aluminum foil, or polyester kraft paper combined with reinforced aluminum foil. Vacuum Super-Insulated R-28 Panels from RParts are sold as an alternative to aerogel products.

We provide fiberglass photographs and identification examples because of frequent questions about how to recognize fiberglass building insulation products.
In some cases the resin binder which gives color to fiberglass insulation can permit an educated guess about the brand or manufacturer of the fiberglass insulation.
In our photo at left you can see some pretty old and extensive thermal bypass leak stains on insulation in an attic. Unless the forensic particle laboratory is making a point of counting small fiberglass fragments in indoor air or dust samples, only a large-particle count may be provided and the presence and potential effects of fiberglass dust may be underestimated. The National Institute of Environmental Health Sciences is one of the National Institutes of Health within the U.S. The major considerations discussed that led the panel to its recommendation include the observations of tumors in multiple species of animals (rats and hamsters). It was a common construction method that employed masonry as infill between the vertical uprights of wood framing." -- quoting the web article review. The text is intended as a reference guide to help building owners operate and maintain their home effectively. While the insulation cost data in the original article dates back to November 1983, the concept of using an R-value normalized cost to evaluate insulation is useful today. However other insulating products may be a better choice depending on other construction details and space limitations. The impact of moisture on the R-value of fiberglass insulation is also discussed (it's low).
The article also discusses the use of polystyrene insulation as a non-structural building sheathing (permitting insulating over building band joists and headers) and as an added control of air infiltration. One solution may be to strap out the siding, though this reduces the savings obtained by eliminating the sheathing in the first place. Fiberglass batts, which are still most-widely used in residential construction, are about R-3 per inch. The material is costly, and fragile, factors that have limited its use in residential construction. The Ultra-R™ R-50 insulating panel is a rigid polypropylene-encased vacuum insulation panel that is custom made to the client's specified dimensions.

Unlike the appliance insulation panels discussed in the original Q&A above on miracle insulation, these Aerogel based panels will continue to retain some, though reduced insulating value if punctured, performing at perhaps R-9 per inch.
The company is researching specialized products in medical, transportation, and aerospace applications. This foam board insulating product is thin, provided in rolls, intended as a thermal break wrap that is moisture, rodent, and insect resistant. As the product literature points out, "All of these components are referred to as a system R-Value. The coating uses a vacuumed microceramic hollow particle (ceramic bubbles) containing a gas,and providing minimal heat conductivity. The panels are produced by a third party manufacturer using DOW INstill foam cores sealed at high vacuum in a special multi-layer gas impermeable barrier membrane film. Cramer is a past president of ASHI, the American Society of Home Inspectors and is a Florida home inspector and home inspection educator.

Department of Energy article on solar domestic water heaters to generate domestic hot water in buildings, explains how solar water heaters work.
DOE, describes the types of fluids selected to transfer heat between the solar collector and the hot water in storage tanks in a building. DOE,using antifreeze mixture in solar water heaters (or other freeze-resistant heat transfer fluids), as well as piping to permit draining the solar collector and piping system. DOE, systems using liquid (typically water) in flat plate solar collectors to collect solar energy in the form of heat for transfer into a building for space heating or hot water heating. If you intend to build an enclosure, you will need some essential facts and information before you build it, otherwise something may go wrong, and you could end up wasting your materials. Using fiberglass really helps to make an enclosure that isn't shaped geometric, like a box.
Making a fiberglass enclosure and making the speaker rings are the first step in my process. In this video i will take you through the steps on making a fiberglass subwoofer enclosure for 2 subs.
This is typically due to dimensional, weight, or hazmat restrictions that prevent us from shipping via UPS, thus requiring a freight quote. It is the resin binder used by the manufacturer to stick the fibers together into a batt or a chopped piece of insulation that give fiberglass insulation its characteristic color.
In our photo below at insulating characteristics you can see the very beginnings of such staining on a white fiberglass batt. Both inhalation and intraperitoneal routes of exposure produced tumors, although inhalation was considered more relevant for humans. If you need to staple up something to not breathe fiberglass dust (that is if you're not going to drywall the ceiling) try housewrap.
The Manufactured Home Owners Association of America is a National Organization dedicated to the protection of the rights of all people living in Manufactured Housing in the United States.
The 4-inch thick EPS foam core panels are laminated with exterior sheathing (OSB) and an interior sheathing (OSB or ?).
These include air, water, water with glycol antifreeze mixtures (needed when using solar hot water systems in freezing climates), hydrocarbon oils, and refrigerants or silicones for heat transfer. Boxes can be built in many shapes, but it is important that the box volume is calculated accurately to achieve maximum performance.
