HIGH HUMIDITY ROOMS
Acclimate panels in the operating humidity conditions. Carefully follow the guidelines in this installation guide for expansion/contraction
spacing and sealing. (see Expansion Joint Chart, pg 5). Failure to seal moisture entry points with silicone sealant can cause swelling
of the substrate resulting in warping, curling, delamination or bond line separation. Use an adhesive that is recommended for high
humidity conditions. A vapor barrier (e.g. 6 mil poly sheet) may be required. *Follow the architect or owner’s specifi cations or check your
local building codes for specifi c requirements.
LOW TEMPERATURE CONDITIONS
Acclimate panels in the operating temperature conditions. Carefully follow the guidelines in this installation guide for expansion/
contraction spacing and sealing (see Expansion Joint Chart, pg 6). Use an adhesive that is recommended for low temperature
conditions.
A vapor barrier (e.g., 6 mil poly sheet) may be required. Follow the architect or owner’s specifi cations or check your local
building codes for specifi c requirements.
FOAM INSULATION
An approved thermal barrier system (e.g., gypsum board) must be used between the FRP
panels and any foam insulation
(Figure 2) . Check your local building codes for specifi c
requirements.
NEAR HEAT SOURCE
FRP panels will discolor when installed behind or near a heat source
which radiates
temperatures exceeding 130°F (55°C), such as cookers, ovens, and deep fryers. Stainless
steel is recommended for these types of areas.
Choose an Adhesive
The following information provides assistance on selecting the appropriate adhesive for installation:
CRANE ADVANCED POLYMER ADHESIVE
Porous and most non-porous substrates, Interior and exterior applications, Fiberglass faced, mold resistant and fi recode core drywall,
drywall, steel, foamboard, vinyl, PVC, FRP,ceramic tile, laminate, sealed and unsealed concrete
CRANE FAST GRAB ADHESIVE
Porous substrates, Interior drywall applications, Non-treated plywood
