1.5” 2” Notes:
(a) Protection covers may be provided on exposed traps connecting to fixtures for the handicapped.
(b) Same as related system. Piping with shut-off valves shall be insulated from system connection to and including shut-off valve; otherwise, insulate all piping.
(c) Insulation thicknesses scheduled are minimum; increase as required to comply with applicable local and state codes. (Listed minimum meets or exceeds ASHRAE Standard 90.1 Table 6.8.3A and 6.8.3B.-2010 edition) (d) High Activity Areas are defined as areas with high traffic or activities that could damage insulation. This includes piping within 8 feet of a walkable surface.
(e) Low Activity Areas are defined as areas with low traffic or limited activities where there is a low risk of damage to insulation. This includes piping work that is concealed from view above hung ceilings, within walls, within pipe or duct shafts.
