Product Overview
1. What is glass wool pipe insulation?
Glass wool pipe insulation is a pre-formed tubular insulation product manufactured from high-quality glass fibers bonded with an eco-friendly thermosetting resin. The material is precision-molded into pipe sections that fit snugly around standard pipeline diameters. It is designed to provide thermal insulation, condensation prevention, and acoustic absorption for a wide range of piping systems in commercial, industrial, and residential applications.
2. What are the key features of glass wool pipe insulation?
Perfect Pipeline Fit
Precision molded tubular structure ensures tight seams without gaps, maximizing insulation efficiency and eliminating thermal bridging.
Anti-Condensation Performance
The material effectively isolates temperature differences between the pipe surface and the surrounding environment, preventing dew condensation and extending pipeline service life.
High-Efficiency Thermal Insulation
With low thermal conductivity (≤0.034 W/(m·K) at 25°C), glass wool pipe significantly reduces heat loss in hot water systems and cold loss in chilled water lines, cutting long-term energy operating costs by up to 30%.
Class A Non-Combustible
Made from inorganic glass fibers, this material is non-combustible (Class A fire rating) and complies with strict international fire safety standards including ASTM E84 and EN 13501-1. It does not contribute to fire spread and withstands temperatures up to 350°C.
High Hydrophobicity
The glass wool pipe features low moisture absorption rate, resisting mold growth and corrosion even in humid environments. This hydrophobic property ensures stable thermal performance throughout the product’s lifespan.
Lightweight & Easy Installation
Light weight and high toughness make the glass wool pipe ready to use without complex processing. The pre-slit design allows quick fitting around existing pipelines, significantly improving construction efficiency and reducing labor costs.
