PUR Duct Foam Board
PUR duct foam board is a rigid closed-cell polyurethane insulation panel specially designed for HVAC air duct systems. It consists of a high-density PUR foam core laminated with durable facing materials such as aluminum foil, color steel or fiberglass cloth. Featuring low thermal conductivity, excellent airtightness, lightweight structure and good mechanical strength, it effectively reduces energy consumption and condensation risk. The board is easy to cut, bond and install without extra insulation layers, widely used in commercial buildings, industrial workshops, clean rooms and central air conditioning projects for efficient and long-lasting ventilation duct construction.

Basic Composition and Material Characteristics of PUR Duct Foam Board
The PUR duct foam board is an integrated composite sheet made of rigid polyurethane foam as the core material. It is a special insulation structural material specifically for heating and ventilation ducts. The core material is formed by closed-cell foaming, with a high closed-cell rate. The internal pores are uniform and fine, which can effectively trap stationary air and achieve excellent insulation performance. The surface of the sheet is usually coated with aluminum foil, color-coated sheet, or non-woven fabric, which not only protects the foam core but also enhances air tightness, moisture resistance, and mechanical strength.
Compared with ordinary insulation cotton and polystyrene board, the PUR material has a higher density and stronger dimensional stability. It is less prone to shrinking and deforming, and is not likely to powder or fall off over a long period of use. The overall weight of the board is light, making it easy to handle and process on-site. At the same time, it has certain compressive and bending resistance, and can be directly used as the wall panel of the duct without the need for additional iron sheet reinforcement, achieving the "structure + insulation + protection" integration.
Core Performance of PUR Duct Foam Board
The plates have excellent airtightness and sealing performance. They are completely dense without any pores. When joined with the special sealing adhesive, the leakage rate of the air duct system is extremely low, ensuring stable air volume transmission and improving the operating efficiency of the air conditioning system. The excellent airtightness can also reduce noise transmission and improve the indoor acoustic environment. It is suitable for places with high requirements for quietness, such as office buildings, hotels, and hospitals.
Environmentally friendly and clean, with wide application scenarios. The surface of the board is smooth and dense, which is not prone to accumulate dust or breed bacteria, meeting the hygiene requirements of clean workshops, hospitals, laboratories, etc. During production and use, there is no obvious dust pollution. Compared with traditional insulation materials, it is more environmentally friendly and conforms to the green and energy-saving trend of modern architecture.
