I expect you're done and went with the Vertical Installation, for your own
protection and least effort. Yes, you want the seams to be tight, little to no
gap. This, is not only so you have as much stud to put screws into, but most
importantly that it provides the best fire protection. No, Horizontal
Installation is based on bold-faced *lies*, there's absolutely no benefit nor
advantage to that stupid practice. Here's exactly what's wrong with Horizontal:
1 DEFECTIVE SEAM - Horizontal rows needing more than one drywall panel
CREATES (instead of AVOIDS) a butt-joint HUMP, which are NOT flat and are a
TWICE (minimum) effort DEFECT. Outlet and switch cover-plates, window and door
trim, baseboards, pictures, mirrors and cabinets dont sit flat. Using ANY
"butt-joint product" erases ALL "claimed benefits" of Horizontal!
2 UNSUPPORTED SEAM Horizontals tapered edge is MOSTLY unsupported,
only 10% (instead of Vertical's 100%) contacts framing, the seam WILL AND DOES
crack. Light switch and countertop electrical boxes within the seam equals
MORE weakness and butt-joint doubled, MINIMUM, efforts.
3 STRUCTURAL DEFECT - Horizontal only reinforces a wall height of 4 or
less and the wall's top-plate is never connected to the bottom-plate. As in
and due to #2 above, Frictional Contact is MINIMIZED (instead of maximized by
Vertical).
4 SEAM DECEPTION...(4'x8' PANELS) Example 1: 48 tall by 102 long
wall, Horizontal = 48 (technically) and its a 24 wide butt-joint
(Vertical = the same, generously, 96 but theyre easy 6 wide joints).
Example 2: 96 tall by 102 long wall, Horizontal = 222 with 50% being
24 wide butts (Vertical = 192 of 6 wide easy joints, yes LESS)...in a
Kitchen Horizontal = 100% of 24 wide butts (Vertical = 0%). Yes, Horizontal
does the taper area twice (minimum) in order to hide its butts, so very
minimally just another 24 was added and #5 below was not factored in to
Horizontal's monumental FRAUD.
5 SELF-DEFEATING ANGLES Horizontal only uses ONE of a panels
tapered edges and PUTS the other taper at the ceiling corner and baseboard,
CREATING (instead of AVOIDING) a twisted angle that MUST be shimmed or
ADDITIONALLY mudded. This too, instantly ERASES ALL claimed benefits of
Horizontal! The Panels are designed to be installed Vertically!
6 UNFRIENDLY SEAMS Horizontal celebrates the chest height seam and
PRETENDS theres no 24-WIDE floor to ceiling butt-joint that needs to be
DONE AND DRY BEFORE doing the ceiling corner (Vertical has easy joints and the
top's done later with the ceiling corner).
7 - FIRE VIOLATION AND HAZARD - Horizontal only fills the coin-thin SEAM'S
FACE and has NO back-blocking, inviting smoke and fires spread, including
fuel-air for a fire's growth (Vertical is full depth and CONTINUOUSLY
airtight).
8 - UNSAFE INSTALLATION - Horizontal needs 2-PEOPLE for a safe installation
and the panel is airborne, literally CREATING the chance to CAUSE injury
(Vertical easily tilts-up with just 1-person). Panel lifters aren't even as
easy and safe as Verticals tilt-up.
9 - ADDITIONAL WASTE - When correctly covering a knee or half wall, tub front,
column or soffit by first removing both tapered edges, Horizontal CAN'T use
the tapers elsewhere (Vertical can and does).
10 - SELFISH IGNORANCE - Foundation and Framing crews go to great pains to
make everything flat, level, plumb and square. Horizontal DESTROYS those
efforts with their DEFECTIVE humps (Vertical keeps them all).
11 - GRASPING AT STRAWS WITH OUTRIGHT FRAUD - Horizontals FALSELY AND
UNKNOWINGLY wave the absurdly INVALID (FPL439) 1983 testing Contribution of
Gypsum Wallboard to Racking Resistance of Light-Frame Walls by the
self-indicted fraud Ronald W. Wolfe. FPL439 found that ALL tapered or paper
wrapped edges must be FULLY INTACT for Horizontal to beat Vertical
"structurally", PERIOD. In the real-world, bottom paper wrapped edges are
REMOVED (at a minimum), BY LAW, for spacing from all floors and thereby
COMPLETELY NEGATE Wolfes inexcusably deceitful and worthless "study" and
summation.
12 - JOINT OR SEAM TREATMENT - According to the ASTM's C840, Horizontal's
joints and seams MUST be mudded to provide ANY fire, smoke and air travel
resistance. Vertical is SO GOOD that it's NOT REQUIRED to have its joints or
seams treated.
13 - FIRE RATING FRAUD - Most Single-ply or layer drywalling for Commercial
Work is required to be installed Vertically, to obtain drywall's actual fire
rating...known by the majority of builders and drywall installers. But, they
only provide Builder's Grade work, the legal minimum with the look expected by
the market. Good for the warranty term with an eternal future of patching and
fixing.
Only promote HORIZONTAL AS WRONG and confidently cite the above incontestable
FACTS.
