External duct insulation

External insulation for ducts

Keep systems running as designed

HVAC ductwork and systems require external duct insulation to keep air temperature and systems running as designed. Investing in a fully adapted external duct insulation solution also has numerous benefits for project owners (reduced energy consumption) installers (lightweight and easy to handle) and occupants (improved comfort).

The benefices of CLIMCOVER external insulation

Thermal insulation

Reduce the amount of heat (or cold) energy needed to maintain the air temperature as designed, while also preventing the formation of condensation.

Superior acoustic properties

Significantly reduce the amount of noise transmitted through the ductwork and pipework in the HVAC system.

Fire safety

To protect building users and occupants with our non-combustible insulation materials, with no contribution of toxic smoke or flaming droplets. For ventilation fire protection discover our Fire-Resistant Ducts.

A choice of external duct and pipework insulation products

Designed to insulate ductwork and HVAC equipment, our CLIMCOVER products are available as boards, blankets, lamellas and wired mats depending on your requirements. They are applied to the wrapped around ductwork and mechanically fixed in position with wire, bands, stapler, self-adhesive or tape.

Lightweight and easy to work with in any conditions
Faced on one side with a reinforced pure aluminium foil that acts as vapour barrier
Reinforced mesh increases resistance to tearing and punching
Flexible and easy to bend over different shapes and parts of the HVAC system
Can be used as shiplap for easy assembly and connection
Easy to cut with standard tools

Did you know…?

Most of these products are made from glasswool with reinforced aluminium foil facing that acts as a vapour barrier. Flexible duct wraps are particularly adapted to external insulation as they can be easily wrapped around outer surface of the duct.
