11Installation instructions for professionals
Half-warm space* can mean a lowered ceiling,
midsole, or casing.
NOTE
The duct coils to be installed in the ventilation
system must be insulated in the same way as the
ventilation ducts are. The ceiling mounting plate is
an optional extra sold separately.
NOTE
Outside air intake duct
(fresh air intake duct)
Cold space:
• 100 mm plate, mat or pipe insulation (+ additional
possible blown wool).
Warm/semi-warm* space and suspended ceilings,
intermediate oor and enclosures:
• Option 1: 80 mm insulation with vapour-tight surface
• Option 2: 19 mm cellular rubber insulation on the
surface of the duct and 50 mm insulation with a
vapour-tight surface.
Insulation must prevent the condensation of water
vapour on the outer surface of the duct. In summer it
must prevent the air from heating up too much.
Supply air duct
Cold/semi-warm* space and lowered ceilings,
intermediate oor and enclosures:
• In basic ventilation, the insulation must be planned
and implemented so that changes in the temperature
of airow are less than 1°C. It is possible to use 100
mm plate, mat or pipe insulation, for example (as well
as possible blown wool).
Warm space:
• Basic ventilation does not require insulation.
For heating and cooling uses, see tables “Insulating
ventilation ducts for heating” and “Insulating ventilation
ducts for cooling”.
Examples of ventilation duct insulation
Soundproong is not included in these insulation
instructions and examples.
Extract air duct
Warm space:
• Basic ventilation does not require insulation.
Cold/semi-warm* space:
• In basic ventilation, the insulation must be planned
and implemented so that changes in the temperature
of airow are less than 1°C. It is possible to use 100
mm plate, mat or pipe insulation, for example (as well
as possible blown wool).
If used for heating or cooling, see tables “Insulating
ventilation ducts for heating” and “Insulating ventilation
ducts for cooling”.
Exhaust air duct
Cold space:
• 100 mm plate, mat or pipe insulation
Warm/semi-warm* space:
• Option 1: 80 mm insulation with vapour-tight surface
• Option 2: 19 mm cellular rubber insulation on the
surface of the duct and 50 mm insulation with a
vapour-tight surface.
Insulation must prevent the condensation of water vapour
on the inner and outer surface.
* semi-warm space = +5... +15°C
