COOLING SYSTEMS AND HEAT GAIN IN DUCT

POORLY INSULATED DUCT = HIGHER RUNNING COSTS
On a hot 40° day the temperature in a roof space can get to 55°-70°C. Most ducted A/C units are installed into roof spaces and blow cold air into flexible duct between 14-16°C. It is the job of the insulation surrounding the duct to keep the air inside it as cold as possible thus avoiding temperature increase (heat gain) as the air travels through the duct to all vents in your system.

GREENDUCT ™ = **LOWER RUNNING COSTS.

HEATING SYSTEMS AND HEAT LOSS IN DUCT

POORLY INSULATED DUCT = HIGHER RUNNING COSTS
On a cold 0-5°C day or night the temperature in a roof space or under a floor is about the same as outside 0-5°C. Most ducted heating units blow hot air into the flexible duct at around 60°C. It is the job of the insulation surrounding the duct to keep the air inside it as hot as possible thus avoiding temperature decrease (heat loss) as the air travels through the duct to all vents in your system.
GREENDUCT ™ = **LOWER RUNNING COSTS.
