– Piping: Apply pipe insulation
with integral vapour retarder jacket to piping and hold in
place by securing the jacket flap. Seal all flaps and butt
strips with vapour retarder adhesive or alternately secure
with staples on 75 mm centres and cover with a heavy brush
coat of retarder coating. Pipe insulation with integral self-sealing
vapour retarder jacket will not require additional fastening.
– Fittings: Insulate fittings with
section of the pipe insulation mitred to fit tightly, or
with tightly placed flexible insulation, then apply reinforcing
membrane embedded in vapour retarder coating. Alternately
insulate fittings with tightly placed flexible insulation
then apply reinforcing membrane embedded in vapour retarder
coating and apply PVC fitting covers.
– Valves, Strainers: Insulate valve
bodies, bonnets and strainers with insulating cement; or
fitted pipe insulation; or mitred blocks all to thickness
of adjacent pipe insulation, then apply reinforcing membrane
embedded in retarder coating. Alternately, insulate with
tightly placed flexible insulation covered with reinforcing
membrane covered with a retarder coating. Drains, blow-off
plugs and caps shall be left uncovered. Alternately insulate
with tightly placed flexible insulation, then apply reinforcing
membrane embedded in vapour retarder coating and apply
PVC fitting covers.
–Flanges: Insulated flanges with
oversized pipe insulation or mitred blocks to the thickness
of the adjacent pipe insulation, then apply reinforcing
membrane embedded in vapour retarder coating. Alternately
insulate with tightly placed flexible insulation, then
apply reinforcing membrane embedded in vapour retarder
coating and apply PVC fitting cover.
