## Notes ##

### Terms ###
* `plasterboard`: see *drywall*.
* `wallboard`: see *drywall*.
* `sheet rock`: see *drywall*.
* `gyprock`: see *drywall*.
* `gypsum board/panel`: see *drywall*.
* `GIB board`: see *plasterboard*.
* `Gibraltar board`: see *drywall*.
* `Drywall`: gypsum in between two sheets of paper to make boards for interior wall and ceiling panels, replacing the earlier *lath* (small wooden slats) and *plaster* approach. The long edge of the boards are tapered, ready for mud and taping, and the short edge of drwall boards are open/butt edged, meaning that paper tape applied between wall and ceiling cause bumps that need to be covered with molding. 
  * Boards in NZ come 10,13,16 by 240, 480, 600 lengths((https://en.wikipedia.org/wiki/Drywall)).
* `tapers` and `mudmen`: those who apply tape and mud to the seams of drywall.
* `mud`: see *drywall compound*.
* `joint cement`: see *drywall compound*.
* `drywall compound`: a white powder of primarily gypsum dust mixed with water to form a mud the consistency of cake frosting, which is used with paper or fiber joint tape to seal joints between sheets of drywall. Comes as either setting type powder (hardens by chemical change, not evaporation, so does not shrink, so good to fill holes, but sets fast) or ready-mix.
  * Applied in 3 coats: *bedding*, *filler* and a *top/finish coat*. Always use a respirator when sanding, and maybe even applying. 
* `bedding coat`((https://en.wikipedia.org/wiki/Joint_compound)): the drywall compound coat applied first, in which to push the paper joining tape. A *tapping compound* (extra sticky) is used.
* `filler coat`((https://en.wikipedia.org/wiki/Joint_compound)): coat to cover the tape that was pushed into the *bedding coat*, and then roughly sanded.
* `top/finish coat`((https://en.wikipedia.org/wiki/Joint_compound)): a fine grain *topping compound* coat to cover the *filler coat*, finely sanded to between 0 (rough) and 5 (super fine), before *primer* then *paint* is applied.
* `drywall clips`: allow for joining two boards together when there is no backing joists((https://www.house-painting-info.com/wp-content/uploads/2014/06/artimg_hyde-bear-claw-repair-clips-in-use2.jpg)).
* `drywall tape`((https://www.thespruce.com/rating-the-best-drywall-tapes-4125930)): see *bedding* and *drywall compound*.
* `furring/hat channels`: channels applied to level and damp proof the hanging of drywall ceilings((https://www.clarkdietrich.com/products/drywall-framing/furring-channel-hat-channel)).
* `Parging`: see *Skimming*. The application of a thin layer of mortar to a wall to cover CMU bricks or defects and provide a finish stucco texture. 
sanding. You hide the bump using *molding*.
* `monolithic claddings`: see *stucco* over mesh, cementboard, 40mm EIFS foam or directly on CMU - as long as it is spaced *and* vented.
* `stucco`: lime based exterior surfacing.

### Recommendations ###

Use [[../Materials/Formance/]] SIP Panels. It adds up to 20% of material cost, but removes the cost of labour in terms of on-site drilling for measuring, cutting, bracing, wiring, insulating. 


### Options ###

* TBD.

### Considerations ###

* TBD


### Specifications ###

Specifications to keep in mind include:

* TBD.




### Suppliers ###

* https://formance.co.nz/
  * Advantages:
    * Cut offsite
    * Faster assembly on site, already with moisture barrier. 
    * Just needs battening & external cladding and internal surface treatment (same as all houses). This just replaces the structure.
  * Considerations:
    * 20% more than traditional stick construction.
      * Cost regained in 4 years.
    * Requires ceiling & wall OSBs to be covered with gypsum boards. 
    * As well as wood floors directly on OSB (no subflooring required).
    * Can be installed to span foundation beams on a slope.
    * If installing on wood foundations, requires a soffit closure of foundation beams to protect OSB from upblown weather.
    * Thinner panels can be installed directly on concrete pad (warning on crunching, leveling, etc?)

### Tools ###

* `Cutter`((https://www.thespruce.com/easy-way-to-cut-big-drywall-1821492))
* `48" T-Square`((https://www.thespruce.com/easy-way-to-cut-big-drywall-1821492))
* `Paper Drywall Tape`((https://www.thespruce.com/rating-the-best-drywall-tapes-4125930)) 
* `Inner metal corners`
* `Outer metal corners`: use 
* `Drywall screws`: have a slightly concave cone head in order to not tear the paper as pushes in.
