Rewall naked board
Introduction:
ReWall Naked Board is a unique landfill-diverting eco-panel made in the USA. It's designed for use as an interior decorative wallboard, ceiling panel, wall tile backer, curvature wall or replacement for fiberglass reinforced panels (FRP). Unlike drywall or sheetrock, it performs much better, is completely non-toxic, and does not off-gas any toxic chemicals. It's not intended for exterior, structural or excessively wet environments.
ReWall is made of 100% recycled content from milk and food cartons that are shredded and then compressed into 4' x 8' wide and 1/2" thick panels. The shreds of recycled paper are left exposed, creating an exclusive design that reads "recycled" at first glance. It has a water-resistant core and is surfaced with a poly-coated paper waste without facing material. All ReWall products are made without glues, water or chemicals, emit no VOCs and achieve the highest rating (10 out of 10) for mold resistance under the ASTM D 3273 test method.

pw equation:
REWALL NAKED BOARD.
PW = 1st Cost + Labor
PW = $0.81 + $2 /SF
PW = -$2.81 /SF Approved.
STANDARD DRWALL.
PW = 1st Cost + Labor + Paint + Maint.
PW = $0.47 /SF + $2 /SF + $0.10 /SF ( P/A , 7% , 60 )
PW = -$10.88 /SF
EAC equation:
REWALL NAKED BOARD.
EAC = $2.81/SF (A/P , 7% , 60 )
EAC = $0.20 SF/YR. Approved.
STANDARD DRYWALL
EAC = $2.47/SF ( A/P , 7% , 60 ) + $0.60/SF
EAC = $0.78 SF/YR.
ROR equation:
PW ( Costs ) = PW ( Benefits )
PW ( B ) = $0.60 SF/YR ( P/A , i* , 60 )
PW ( C ) = $2.81/SF
$2.81 SF / $0.60 = ( P/A , i* , 60 ) = 4.6833
i* = 21.55% Approved.
B/C equation:
BENFITS = $0.60 SF/YR ( P/A , 7% , 60 ) = $8.42 /SF
Cost = $ 2.81 /SF
B/C = $8.42 / $2.81 = 2.99 Approved.
