There is no basis for that statement. All are made from natural gypsum or CaSO*4 (H*20) derived from manufacturing processes, primarily as a by product from the power generation industry. Type X and proprietary 1/2" boards meant to be used in fire rated assemblies have an appreciable amount of fiberglass imbedded in the matrix for added strength.

Please read up at the Gypsum Association web site.

But as it stands, your explanation is fiction

Check the ash content of Chinese drywall.

Chinese drywall was incorrectly made and was falsely marketed. That fact does not change the definition of drywall, sheetrock or gypsum wall board. They are all synonymous and equal, and you have absolutely no basis in fact or definition to make a distinction.

Gypsum board is made from gypsum. probably as with many things today. it contains less then it did 30 years ago.

Drywall, sheetrock or gypsum wall board are made from CaSO 4 (H20), which is either the evaporate mineral gypsum or a by product of de-sulphurization of flue gasses in coal fired power plants. There are some binding materials, and fiberglass is found in fire rated board.

Again, there is no difference between sheetrock, GWB or drywall, as you claimed. There is also no requirement that gypsum be strictly used. Man made "gypsum" is allowed by both the UL and the Gypsum Association

Gypsum board has more gypsum then drywall.

There is fire rated drywall, but its made differently.

Stop it, there are no differences except in semantics. You are destroying any bit of credibility people had for you.

From the Gypsum Association Fire Resistance Design Manual

Quote:
Gypsum Board - Defined in ASTM C 11, Standard Terminology Relating to Gypsum and related building materials, as "the generic name for a family of sheet products consisting primarily of gypsum with paper surfacing" Gypsum boards may further be described as follows:

Regular Gypsum Board - a gypsum board with naturally occurring fire resistance from the gypsum in the core; or

Type X Gypsum Board - a gypsum board with special core additives to increase the natural fire resistance of regular gypsum board
Right there, you arguement that gypsum board is a product entirely different that "fire rated drywall" is turned on its ear. Standard 1/2" board, Type X, shaftliner, water resistant, soffit board and glass rock are all considered by the ASTM and the Gypsum Association to be gypsum board. Common and trade usage further sperates paper backed 1/4", 3/8", 1/2" and 5/8" gypsum board as sheetrock and drywall. But this is just a trade usage, and for you to continually and stridently argue that there are fundemental difference between "sheetrock", "drywall" and "gypsum board" when there are none is sadly laughable.

The Chinese product was a 1/2" material. You claimed that drywall was a fire rated material, which is generally 5/8" thick

Attached garage, fire codes violation?


I live in a house built in 1989 that I bought 5 years ago. There was a home inspection done as part of my purchase, the bank required it. No items about the attached garage were noted. The interior walls of the garage are covered with 1/2" foil covered foam and 1/2" OSB over the foam. The ceiling has just the 1/2" OSB.

A month ago I added an electrical sub-panel in the garage. The work was permitted and I had it inspected.

Here is a picture showing the sub on the OSB covered walls. The garage abuts my laundry, kitchen and dining room.




I asked the inspector about the wall covering, he shrugged and said it was done back in the 80". I am at least the third owner of the house and it apparently has never been questioned before. I probably will stay here forever so it will be my kids problem when they have to sell the house. But in the rural area I live in, I doubt it will ever be an issue.

if your garage butts to a gable end the new material needs to go to the highest point of the new roof

Pretty sure I said that they make a fire rated drywall.

It has a letter designation, but its not X. And it is made different then X gypsum.

http://en.wikipedia.org/wiki/Drywall

From the article in Wikapedia...

"Type X" drywall is formulated by adding glass fibers to the gypsum, to increase the resistance to fires, especially once the hydrates are spent, which leaves the gypsum in powder form. Type X is typically the material chosen to construct walls and ceilings that are required to have a fire-resistance rating.

Also...

http://en.wikipedia.org/wiki/Gypsum







From the article




Synthesis

Synthetic gypsum is recovered via flue gas desulfurization at some coal-fired electric power plants. It can be used interchangeably with natural gypsum in some applications.

But in the first post, you said not to use drywall or sheetrock, because it "wouldn't pass (fire) code". Now there is a fire rated drywall, distinct from gypsum board?

Oh lord, are you sent here to punish us? It really isn't that difficult to understand. It basically works out that you're wrong and won't admit it.

Have you ever looked at a set of plans by a registered architect? They refer to everything as GWB
