Piping: Apply pipe covering with integral vapour barrier jacket to piping and hold in place by securing the jacket flap with staples on 75mm centres. Pipe covering with integral self-sealing jacket will not require additional fastening. Seal all flaps and butt strips with vapour barrier adhesive or alternatively secure with staples and cover with a heavy brush coat of barrier coating.
• Fittings: Insulate fittings 75mm diameter and less with flexible insulation secured in place with 1.62mm stainless steel wire and finish with reinforcing membrane embedded in a heavy brush coat of barrier coating. Insulate fittings over 75mm diameter with sections of pipe covering mitred to fit tightly with each mitred section secured in place with a minimum of one loop of 1.62mm stainless steel wire. All voids and cracks to be filled with insulating cement, then cover the entire fitting with reinforcing membrane embedded in a heavy brush coat of barrier coating.
• Valves, Flanges: Insulate valve bodies and flanges with fitted over sized pipe covering, or mitred blocks to thickness of adjacent pipe covering, then apply reinforcing membrane embedded in barrier coating. Alternatively, insulate with tightly placed flexible insulation covered with reinforcing membrane, stapled in place and covered with a barrier coating. Drains, blow-off plugs and caps shall be left uncovered. (See Note 1).
