Sheetrock and Firerock

You are at the wrong place.

You need to contact your local planning office for codes and zoning and get the skinny from them.

I am sure you will get lots of opinions from here, but none of them know your local codes (myself included) and they can't be held legally responsible if you build something that the zoning officials tell you is unsatisfactory and must be torn down.

You may need to employ an architect and you almost certainly will need a building permit.

I can't imagine why anyone would waste time and money soliciting advice from any other place than the agency that has to certify it.

Type "X" sheetrock is fire-rated. Typically, a continuous layer of 5/8" Type "X" will satisfy local code. Anonymous Hero is correct, you need to check with your local building department.

In my experience, even though local authorities state that they follow the latest version of IBC (International Building Code), they often have more stringent requirements for fire rating. However, my experience has been with residential building that has stricter requirements relative to fire.

In all actuality they are the same. However, 5/8" type X sheet rock has a fire rating of half an hour.(on the back side of every sheet there are stamps that will verify type X) To obtain a one hour fire rating (standard for commercial construction) is one layer of 5/8" type X sheet rock on each side of a wall with a minimum of 1 1/2" framing member (wood or metal) in between. Hope this helps.

Depend what you are building , go to the next site WWW.HEBEL.COM or WWW. HEBEL.DE

Where you can find any kind of BLOCKS AND PANELS OF AAC 2 or AAC 4 with good properties for heat & fire, sound & seismic properties.
