Thermal insulation solutions for air ducts.

Insulating air ducts helps the control the temperature within the ducts and to prevent the ducts from leaking air, resulting in greater energy consumption and costs. Heat loss through the duct walls is also an expected and inevitable drain on the system. Effective thermal insulation of the ductwork reduces this heat loss and helps to minimize energy usage.

Cool air passing through warm areas of a building can cause condensation and dripping, which could lead to mold growth, corrosion and multiple safety issues. Condensation can form on duct surfaces with a temperature either equal to or lower than the dew point. This moisture can become a hotbed for microbial contamination and corrosion.

Without proper air duct insulation, up to 30% of the energy used to heat or cool your facility could be lost. Air duct insulation can help limit energy waste, leaks, temperature drops, and condensation buildup. A closed cell insulation can help limit moisture ingress than can lead to energy losses, build-up of condensation, and the consequences that go along.

FOAMGLAS® insulation is a preferred insulation material for air ducts because of it consists of closed glass cells, and is water and vapor tight which helps limit risk of corrosion under insulation and the buildup of mold and bacteria. It also eliminates the need for an extra vapor barrier.

FOAMGLAS® insulation provides great thermal properties and helps avoid the outside air duct surface from cooling down and creating condensation. It helps create an efficient way of cooling your building and saving on energy costs.

It also does not burn or give off smoke in case of a fire. That is one of the reasons why FOAMGLAS® insulation is often a preferred material for air ducts in densely populated buildings.

Typical Configuration for air ducts

  • A single layer system of FOAMGLAS® insulation
  • Joints shall be sealed with a PC® sealant appropriate for the application
  • Coating or cladding shall be applied for aesthetics or where mechanical protection is required
