Example
For a damper size of 910mm x 925mm.
Area = 0.85 msq
Vertical Installation
Insulation Thickness = 75mm (line 2 of table)
Insulation Length = 975mm (refer to graph)
Horizontal Installation
Insulation Thickness = 40mm (line 4 of table)
Insulation Length = 975mm (refer to graph)
Insulation Thickness = 75mm (line 5 of table)
Insulation Length = 725mm (line 5 of table)
Note: for circular, use square base damper area.
