Glass wool board for HVAC insulation
Wahlee HVAC special glass wool board is made of uniformly slender glass fiber and environmentally friendly adhesive through special processing. According to the required R-thermal resistance value, different types of high-density boards are made according to different unit weights, which are suitable for external insulation of rectangular metal air duct systems. At the same time, Wahlee can provide various waterproof and vapor facing materials required for glass wool boards, which are processed and compounded on cotton boards in the original factory to meet the insulation and moisture-proof requirements in various environmental situations. Using Wahlee's glass wool boards for air ducts can greatly reduce the cold and hot losses of air duct walls and the operating costs of HVAC systems, with beautiful appearance and excellent insulation and moisture-proof performance. : 4008215192
| Introduction
Glass wool is a product made by using a unique patented centrifugal method technology to process molten glass fiber and applying an environmentally friendly formula adhesive based on thermosetting resin. It is an elastic felt made of glass fiber filaments with a diameter of only a few microns. It can effectively confine air, thus playing a role in insulation, sound absorption, and safety protection. It is the best material for insulation, sound absorption, and noise reduction.
| Performance
The selection of product specifications is usually determined by two factors:
1. The requirement for maintaining the thermal resistance value (R value) of the structure is determined by the climate conditions of the building location: R=T/K (T - thickness of glass wool felt, K - thermal conductivity of glass wool felt), so that the required specifications of glass wool felt can be calculated< Br> 2. Requirements for controlling condensation and condensation in the working environment of buildings: In addition to being related to the temperature of the working environment, condensation and condensation are also related to the relative humidity of the indoor air. To control condensation and condensation, it is required to use thermal calculations and responsive glass wool felt to make the surface temperature inside the building higher than the dew point temperature.
