[edit] GRP Merge

Why on earth should this article be merged with glass reinforced plastic? They are two separate chemical entities. A section added to the Fiberglass article about its uses in plastic might be appropriate but that's it. Pschemp 03:31, 24 Nov 2004 (UTC)

[edit] adsorb

I wrote the original article with the word ADSORB because glass is incapable of ABSORBing moisture. Def of ADSORB: the adhesion in an extremely thin layer of molecules (as of gases, solutes, or liquids) to the surfaces of solid bodies or liquids with which they are in contact -- so the person who edited adsorb to absorb was incorrect. Water molecules do not generally absorb into glass fibers. In order to do that, the molecules would have to enter the fiber. Glass is too rigid for this and can only adsorb water.

Integrated link to adsorption page to prevent future cases of the same - and enlighten those that did not know the difference (me included) Egil 09:11, 7 Dec 2004 (UTC)

[edit] Grammatical error?

Is'nt the quotation in the first paragraph slightly wrong? it says: "... has attained so high a degree of viscosity and to be for all practical purposes rigid.", but the and should be something like "as" (As I have not read the original text, I do'nt want to change the article myself). --Talleyrand 13:19, 8 May 2005 (UTC)

[edit] Fibreglass is not GRP, GRP is not fibreglass, GRP contains glass fibres

I agree with Pschemp - by all means (in fact please do) add a paragraph and a link in the fibreglass article to highlight a common parlance, and incorrect, use of the term, but do not merge the two articles. You might as well merge steel & concrete on the basis that the former is often used to reinforce the latter....

[edit] Pele's Hair for high strength fibers?

Since there are basalt fibers and glass fibers, has Pele's Hair been used for fibers? Has it been tested for strength?

[edit] Glass Fiber -> Fiberglass

Since glass fiber redirects to fiberglass, I've added a See Also to Optical fiber. I think this might be better put as a disambiguation at the top of the article, but I'm headed to bed for tonight. Whig 06:57, 20 Jun 2005 (UTC)

(I'm not too familiar with editing Wikipedia, so maybe I'm asking this question at the wrong place) Isn't Fiberglass the same thing as Glasswool? If so, I suggest a merger between the two pages.

[edit] Mixture of units

There seems to be a mixup of units in the last paragraph under Chemistry, using SAE (inches) to define the length of the fiber when the rest of the units are in Metric. Can anyone check the source and confirm if that's as-printed? If so, an alternate source may be necessary (as well as a tip to the editor of the book.)


The discrepency comes from the practice of all textile literature being written in english units even when every other science on the planet had switched to metric. The industry today still uses both. It is confusing but not actually wrong. If someone wants to do conversions for the sake of continuity that is fine by me. Pschemp 00:04, 23 September 2005 (UTC)

[edit] Fiberglass health effects

How come this article lacks any mention of the controversy over the potential negative health effects of fiberglass? As such it doesn't seem completely NPOV. --Cab88 00:39, 7 November 2005 (UTC)

Insulation glass fibres which evade the body's natural defences (mucous membranes etc.) dissolve in the alkaline environment of the lung. The 'controversy' is artificial or at least misguided. IARC have removed insulation glass fibres from their 'possibly carcinogenic' classification. --Miller nz 09:40, 10 February 2006 (UTC)

Interesting...that should all still be documented in the article, however; the claims and popular beliefs of health risks as well as contrary studies and findings. Postdlf 17:20, 9 May 2006 (UTC)

[edit] Health Section

As it was written this was blatant copyvio from the site referenced in the article. It also lacks citiations and as such I removed it to protect wiki[edia from legal liability. pschemp | talk 13:12, 30 March 2006 (UTC)

In 2001, the International Agency for Research on Cancer (IARC) removed insulation wool fiber glass from its list of possible carcinogens. http://www.iarc.fr/ENG/Press_Releases/archives/pr137a.html . That action was based on a large body of both animal and human data. The animal data are from a series of long term inhalation studies in rats performed by RCC Consulting in Geneva, Switzerland. The human data were in the form of an updated epidemiology study performed by the Univ. of Pittsburgh. The IARC 2001 action reverses its prior action in 1987, which put fiber glass on the possible carcinogens list based on largely on intraperitoneal implantation studies in animals.

More recently, the National Toxicology Program (part of the US Health and Human Services Department) is currently considering adopting for the US the IARC 2001 action. http://ntp-server.niehs.nih.gov/index.cfm?objectid=03C9C639-E7CC-CB6A-83088F12A2BA4DBE . That action would remove insulation fiber glass from the US list of substances “reasonably anticipated to cause cancer.”

Point of full disclosure – I work for Johns Manville, which makes a full line of naturally white Formaldehyde-freeTM fiber glass building insulation. As you can imagine, fiber glass health issues are important to us and we watch the science very carefully. I am concerned that several of the references at the end of this article are old and pre-date the IARC 2001 action. In addition, the Manufacturing Processes do not describe the JM HERM process, which is newer, uses less energy, and is lower emitting than older processes. bruceray-jm 9-16-2007 —Preceding unsigned comment added by Bruceray-jm (talk • contribs) 03:34, 17 September 2007 (UTC)

[edit] GRP & FRP

WHAT IS THE DIFFERENCE BETWEEN GRP AND FRP?

[edit] History of fiberglass

If there is any information in this article that can be sourced and proven, it should be merged into Fiberglass. No reason exisits to have a separate article covering this, as it all belongs on this page. This is a Good Article already though, so just dumping unverified information in would be detrimental. pschemp | talk 22:20, 9 August 2006 (UTC)

The article about History of Fiberglass is not comprehensive enough. A major disinction between insulation and textile fiber glass (and later reinforcement) should be made. Also it presents Owens Corning as the inventor of glass fibre whereas other companies and individuals have contributed to the development of glass fibre. 16 August 2006.

Although others contributed, the inventor was Owens Corning. Saying someone invented something inno way insinuates other's didn't work on it, but the they have the first patent. pschemp | talk 17:59, 21 October 2006 (UTC)

[edit] Don't merge in History

There seesm to be a trend building among some editors to over-merge articles. One of the advantages of an online system is the ability to be modular. Keeping articles separate but linked can save a great deal of time for users. I would suggest a summary history here linked to a detailed history elsewhere. Kevin Murray 17:53, 21 October 2006 (UTC)

[edit] Effect (or lack thereof) on Health

I specifically came here looking for info on the effects of fiberglass on health (or lack thereof) but there is no mention in the article at all and the links at the bottom seem quite old. I think, in the U.S. anyway, it is still a fairly common belief that fiberglass is harmful to your health, and some information on such (even if just information pointing out why this belief is false) should be included in the article. 124.84.185.165 11:02, 8 November 2007 (UTC)

[edit] Density

What about the fiberglass density? I have read in other pages that is about 2.6 g/cm3, but I haven't found anything in this article. 85.50.238.186 (talk) 19:38, 26 November 2007 (UTC)

[edit] Merge from Glass wool

Is glass wool the same thing as fiberglass? Should the former be moved into the main article?ilgiz (talk) 08:59, 2 April 2008 (UTC)

[edit] Section on Fiberglass Sheet Laminating Operation needs help

The section Fiberglass Sheet Laminating Operation is poorly written, uses inconsistent British spellings (e.g. mould instead of mold and fibreglass instead of fiberglass), and uses a lot of "you" phrases that sound how-to-ish. I started to work on this, but I know too little about the subject to accurately paraphrase it into encyclopedic prose. Can someone more knowledgeable help here?
