Wan Rui Weil® bio-based environmentally friendly glass wool board is made from uniformly fine and long glass fibers and an environmentally friendly binder through a special process. According to the required R-value, it is made into different types of high-hardness boards with different densities, up to 96kg/m3, suitable for external insulation and heat insulation of rectangular metal duct systems.
Wan Rui Weil® can provide various waterproof and vapor-proof facing materials required for glass wool boards, and composite them on the glass wool boards at the factory to meet the requirements of heat insulation and moisture proof in various environmental situations.
Using Wan Rui Weil®'s duct glass wool board can greatly reduce the cold and heat loss of the duct wall and the operating cost of the HVAC system. It has a beautiful appearance and excellent heat insulation and moisture-proof performance.Physical Properties

A2 levelAverage temperature—refers to the arithmetic average of the temperature of the air inside the duct and the outside air.
The above test conditions are all for glass wool boards without facing, and the data are nominal values.
Data source: Detection report from the National Glass Fiber Product Quality Supervision and Inspection CenterPrecautions
Preventing condensation: Environmental temperature, relative humidity, duct operating temperature, and the thermal conductivity and thickness of the insulation material are the main parameters that determine condensation.
Energy saving: Preventing condensation is only the most basic requirement for insulation. To save energy and reduce operating costs, it is recommended to refer to energy-saving standards to select appropriate product specifications. To make product selection more accurate, it is recommended to contact the local sales personnel of this company. Wan Rui Weil will provide technical support services.
Correct installation: Please refer to relevant national standards, or contact local sales personnel. Wan Rui Weil will provide technical support services.R-value: (at 25℃)
