42mm Koolduct Duct Board

20-22-30-42mm Koolduct duct boards refers to a specific type of insulation board used for HVAC (Heating, Ventilation, and Air Conditioning) ductwork. The term ""42mm"" indicates the thickness of the board, while ""Koolduct"" is a brand name often associated with high-performance pre-insulated duct systems.

Koolduct duct board is known for its lightweight and rigid construction, making it easy to handle and install. It is typically made from a foam core, such as rigid polyisocyanurate (PIR) or phenolic foam, which provides excellent thermal insulation properties. The foam core is usually sandwiched between two layers of reinforced aluminum foil or other facing materials to provide strength and protect the insulation.

The insulation properties of the 42mm Koolduct duct board help to prevent heat transfer and minimize energy loss in HVAC systems. It is commonly used in commercial and residential buildings where energy efficiency is crucial. The rigid construction of the board ensures that the ductwork maintains its shape and integrity, reducing air leakage and improving system performance.
