Fireproof PU Air Ducting

Polyurethane (PU) Foam Pre-Insulated HVAC Ductwork Panelis a high-performance, all-in-one solution designed for modern heating, ventilation, and air conditioning (HVAC) systems. Built with a precision-engineered sandwich structure, it features a dense polyurethane (PU) foam core-celebrated for its exceptional thermal insulation properties-sandwiched between two protective layers of corrosion-resistant aluminum foil. This factory-prefabricated panel merges insulation, structural strength, and airtightness into a single component, eliminating the need for separate insulation installation and streamlining ductwork setup in diverse buildings.

Compliance Standards and Environmental Attributes of Fireproof PU Air Ducting

Safety Compliance: The fire resistance rating reaches non-flammable B1 level. It complies with international standards such as GB 8624-2012 and EN 45545, and the smoke toxicity meets the standards.

Environmental Safety: It does not contain harmful substances such as CFC, formaldehyde, and free benzene. It meets the environmental limit standards for building insulation materials and is green and pollution-free.

Scene Restrictions: It is not suitable for acidic or alkaline environments and smoke exhaust and prevention systems. In high-pressure scenarios, specialized reinforced products need to be selected.

Installation and Maintenance of Fireproof PU Air Ducting

01.

Modular installation

Standardized production of panels (standard size 1200mm×3950mm, customizable length available), fixed by tongue and groove splicing or bolts. The average daily installation area per person can reach 30 square meters, which shortens the construction period by 50% compared with traditional on-site spray insulation.

02.

Low maintenance cost

The surface coating is easy to clean and only requires wiping to remove dust on a daily basis. If there is local damage, it can be filled with a special PU repair agent without the need for overall replacement. Its service life can reach 15 to 20 years, during which no frequent maintenance is required
