Polyurethane sandwich panels are highly efficient and energy-saving building envelope materials that integrate multiple excellent properties and are widely used in various construction fields
Performance advantage of PU Foam HVAC Ductwork
1.1 Outstanding thermal insulation and heat preservation performance: With a low thermal conductivity and excellent thermal insulation performance, the insulation effect is twice that of ordinary polystyrene boards at the same thickness. It can effectively reduce heat exchange between the inside and outside of buildings, lower energy consumption and save energy.
1.2. Excellent fire resistance and flame retardancy: It has passed the test of the National Quality Supervision Center, and the combustion grade meets the GB 8624 B2 standard. Polyurethane itself is non-flammable, providing reliable fire safety guarantee for buildings.
1.3. Outstanding air tightness and sound insulation: It has a good sound absorption effect, can significantly reduce the noise transmitted from the outside, and create a quiet and comfortable indoor environment.
Application field of PU Foam HVAC Ductwork
1.1. Public buildings: Applicable to airport and railway station waiting halls, stadiums, theaters, exhibition halls, etc.
These buildings have large Spaces and high requirements for the lightness, insulation, fire resistance, water resistance, sound insulation and durability of the panels. Polyurethane sandwich panels can meet these demands.
1.2. Industrial plants and warehouses: Due to their advantages such as light weight, efficient installation, and flexible layout, they have become the first choice for single-story factories.
In multi-story industrial plants, it can not only be used for the roof but also for the flexible layout of the exterior walls, and the appearance of the building can be beautified through the diverse colors and shapes of the color-coated steel sheets.
For industrial buildings with constant temperature and humidity requirements, its excellent thermal performance can reduce operating costs.
