Talk:Mineral wool

some corrections
I have made some corrections to the page in terms of common errors and misconceptions that were listed in the previous version. For those who are interested, I refer you to my article on the topic, which was previously published in the Construction Specifier, a trade magazine published by Construction Specifications Canada : http://www.geocities.com/astximw/mmmf.html --Achim 04:35, 25 April 2006 (UTC)

Mineral wool -> Stone wool?
The term Stone wool is re-directed to this article which is about the production of stone wool. To the best of my knowledge, mineral wool is the super-type of stone wool and glass wool. I think that this article should be renamed to Stone wool and then a new page Mineral wool should be created to point at the two sub-types stone and glass wool. - VicVal 18:06, 7 August 2006 (UTC)


 * That would be splitting hairs. Stone is made of minerals, which is metal oxides. All mineral wool is made of that, regardless which of the three types you look at. The main constituents in these wools, you will all find in abundance in our lithosphere. I know, as My dad sold it starting in the sixties and I have lived near the stuff for decades, in one form or another. If you do some digging on the net, you will come to the same conclusion. Each of the three types are made of metal oxides (just in different combinations and hence the different melting points and cost variation), which is the same as stone. So there is no point splitting hairs about it. If it walks like a duck and it quacks like a duck...its probably a duck.--Achim 02:27, 15 August 2006 (UTC)
 * I agree with the original poster. The article does not explain what rockwool or stonewool is, but talks about it as if it were defined in another article. More explanation needs to be added (rather than expecting to reader to google elsewhere). —Pengo talk · contribs 02:04, 16 September 2006 (UTC)


 * Sometimes it is asbestos wool, who knows what is in that rock, mineral or ceramic wool. PrinssiFO 22:58, 29 September 2007 (UTC)


 * At least some commercial products referred to as stone wool have different properties than fiberglass. Three that come to mind are that stone wool is recommended for acoustic insulation and fire resistance, but not for thermal insulation.  It is also resistant to mold, and will maintain its properties after getting wet and subsequently drying.  Regarding mold, it has passed the mold tests in ASTM C1338.  Although the three materials mentioned as well as others may be classified as fibers made of minerals, their characteristics and uses are different.  Specifically, "ROXUL" products are inorganic which provide no food source for mold to grow. ROXUL products are tested to ASTM C1338 – Standard Test for Determining Fungi Resistance – and pass with zero fungal growth."  "WHAT IS STONE WOOL?


 * ROXUL insulation is a rock-based mineral fiber insulation comprised of Basalt rock and Recycled Slag. Basalt is a volcanic rock which is abundant in the earth, and slag is a by-product of the steel and copper industry. The minerals are melted and spun into fibers." I don't know the wikipedia rules for citing material on a company web site, but believe that stone wool should be a separate entry from fiberglass and ceramic fibers.

 * Agreed – article needs to include more specifics. – Down time (talk) 16:17, 16 March 2018 (UTC)

History?
When were these types of insulation materials first produced? —The preceding unsigned comment was added by 67.136.145.222 (talk) 10:10, 6 May 2007 (UTC).

So, what is it?
The article says: “Stone wool is a furnace product of molten stone”. That strikes me as bloody imprecise for an encyclopedia article. There are thousands of substances that “stone” can refer to; most of them can be melted. Freederick 01:44, 5 August 2007 (UTC)

It is made from stone, and very usable for insulation. A lot of stone types are available. What type of stone isn't very important when it is stone wool. I bet they don't use gemstones. PrinssiFO 23:09, 29 September 2007 (UTC)

The rockwool factory Pencoed wales told me (2012) that they used basalt from Ireland but different rocks and blends were used for different products. They aslo said it was first noticed in Hawaii where lava was blown by the wind into fibres. I do know they add an 'oil' to make the fibres more waterproof in the final product.Offbeam (talk) 22:23, 15 March 2012 (UTC)

It's sand/rock/gravel that's been spun like cotton candy.

Mentioned mergefrom
I found an article about "synthetic mineral fibre", and I found it jenerally inferior to this article, so I sujested a merger. Considering it for a minute, I think I'll just boldly insert the redirection. I don't think many people care for safety assessments in the passive voice, which seems to be what "smf" is all about.

Ceramic versus Stone
Isn't ceramic basically igneous and typically porous stone? So, how do you compare them, as in rating ceramic above stone? BrewJay 08:02, 24 October 2007 (UTC)

High temperature insulation wool
A new high temperature insulation wool article has appeared. It's quite good, but both this article and it need work now to clarify their relationship. Ccrrccrr (talk) 11:12, 25 July 2008 (UTC)

Trademark status of ROCKWOOL
The paragraph advising that ROCKWOOL is a registered trademark was badly written, and on researching the trademark status I found it was not a registered trademark in the United States. Further, an EU trademark was refused. See trademark distinctiveness for the probable reason: under U.S. trademark law, "rock wool" is merely a description of the product in English. In fact, the U.S. trademarks held by ROCKWOOL International (for example, HORTIFIBER ROCKWOOL®, US Trademark 3393071) have the disclaimer "No claim is made to the exclusive right to use ROCKWOOL apart from the mark as shown."

Edit request – More information required for Safety section
Will someone with expertise in this area please add a complete list of common names (along with any brand names) of products that are considered mineral wool, each accompanied by the specific elements they contain? Without this information the "Safety" section of this page is of zero use to laypersons. The Wikipedia pages of IARC's (International Agency for Research on Cancer) carcinogenicity categories include only the compounds used to create these types of fiber – the lists do not use the terms "mineral wool", "slag wool", "glass wool", "stone wool", etc. – Down time (talk) 16:11, 16 March 2018 (UTC)

The "Floor Insulation" section seems out of place?
It looks as if it was copy-pasted, maybe from a contract proposal, maybe from a technical paper. In any case, it doesn't seem to add to the reader's information about rockwool/mineral wool. Would anybody object if I remove it?
