End Notes | Important

 
1. Tests of the Green-Zip™ Partition conducted at the direction of and in the presence of IRS Senior attorney and engineers, and member of Deloitte-Touche & the Chair of USGBC Houston, reveal that only Green-Zip™ Tape performed to their approval. Other fiberglass mesh and paper tapes failed to obtain their approval even when allowed to use the patented method for installation & disassembly. Other joint tapes failed to be acceptably removable. Green-Zip™ Tape is licensed to use the patented methods for installation and removal. WARNING: Use of any other brand of joint tape could constitute patent infringement and subjection to damages, court cost, legal fees, and mandatory removal of all drywall from the building (even with tenants present) plus disallowance of IRS benefits plus penalty and interest. It is often wise to be honest.
 
2. Where partitions extend to a deck above that is subject to deflection (i.e. particularly at roof decks) install expansion joint type head tracks with extended legs, stop studs short of deck the required distance & stud gauge as per engineer, do not screw studs or sheathing panel to head track as required to allow deck to deflect. Screw sheathing to studs (not into head track) as required to allow deflection, typically about 2" below the bottom of head track leg.
 
3. Use at least 22 gauge metal studs at 2' on center for interior non-load bearing partitions; Stronger may be required if over for 10' tall or where they support a load such as cabinets or shelves.
 
4. See footnote "C"
 
5. Cut drywall panels so as to not have joints near door or window corners; no taping over joint compound; USG Construction Handbook recommends 3 piece door & 4 piece window frames, see Handbook when 1 piece frames are used; Store & install tape above 55 degrees Fahrenheit.
 
6. Only if the space is exactly 8 feet tall is there any potential benefit to use 4'x12' sheathing panels laid horizontally—if more than two 4' wide panels are required to reach ceiling height the lineal feet of joints to be taped & floated is increased by horizontal installation. For more info contact Green-Zip.
 
7. The screws at the butt joints should be evenly spaced. Typically about 7 screws per 9' edge on a 9 foot tall wall or 18" on center unless otherwise specified by architect or required by code.
 
8. Drywall with normal mesh tape cannot be disassembled: First, because doing so infringes patents noted herein. Second, once the mud compound has "fully" cured it will break the tape if it is pulled up. A drywall, (except for Green-Zip Partition) has to be demolished (rather than disassembled) and then transported to a landfill. Gypsum sheathing is known to create poison hydrogen sulfide gas only when placed in a landfill and is banned in many areas (organic matter, moisture and lack of oxygen cause a fungus to grow that produces the highly poison gas). Therefore, the gypsum sheeting has to be laboriously separated from the studs and other construction waste. Even after it is separated from studs and other construction waste the used gypsum sheeting is not yet a ready candidate for "recycle" due to paint (and fiberglass in commercial sheathing). Further, "reuse" of sheathing is much better than "recycle"; and reuse is readily accomplished by use of the Green-Zip™ Partition.
 
9. We recommendation against Green-Zip Tape use at corners, ceilings, etc. because they have little or no effect on increasing the amount of drywall that can be reused or easily separated for recycle; and/or to avoid being entangled in disputes related to deck deflection or to curing cracks—understandably not the fault of Green-Zip tape because it is many times stronger than ordinary tape.
 
10. See second part of footnote above.
 
11. LIMITED WARRANTY provided by and MAXIMUM LIABILITY of seamless demountable drywall products manufacturer, inventor, patent holder and related entities is for a period of 3 years after the initial installation; and is limited to replacing the tape; and to validate this LIMITED WARRANTY the tape must break under normal use and fail to expose the screws for removal where all information and recommendations in this specification are strictly adhered to. Such breakage is a most unlikely event because Green-Zip Tape is many times stronger than ordinary drywall joint tape. Further, Drywall failures and cracking are almost exclusively due to 1) improper installation: a) inferior joint compound; b) improper curing due to humidity and temperature, rushed schedules; or painting over compound before deeply cured (rather than just surface cured); and/or 2) building or deck movement; none of these are within the control of the drywall joint tape manufacturer.
