Fire rating -
Intumescent Coatings are constructed
in such a way as to achieve a
code-determined
resistance rating, thus
forming part of a fire compartment's passive
fire protection. Fire Retardant Coatings can
be spray applied to the rated wall assembly.
Design loads –
Retardant Coatings must withstand
a minimum 5 lb./sq.ft., and additional
seismic loads. This does effect the
Intumescent Coatings.
Germany includes repeated impact force
testing upon new Fire Retardant Coatings systems. Other codes
require impact resistance on a performance basis
Retardant Coatings typically extend through the
roof and terminate at a code-determined
distance above it. They are usually finished
off on the top with flashing (sheet metal
cap) for protection against the elements.
Coat with Retardant Coatings like you
would a Flame Retardant Spray and this will
be very clean and easy to achieve.
Materials -
Retardant Coatings in North America
are usually made of
concrete block or
reinforced concrete.
Barrier walls are
typically constructed of
gypsum board
partitions. Intumescent Coatings are
applied to any type of gypsum assembly.
First check to make sure you have the proper
testing. Coatings on a wood assembly are
very attractive
