Deploying premium NBR/PVC elastomeric structures and heavy-duty structural membranes to ensure optimal thermal performance, vapor barrier integrity, and acoustic dampening across HVAC systems.
In modern industrial and commercial construction, thermal integrity, mechanical protection, and vapor control are the cornerstones of energy-efficient design. Ductwork systems, which process extreme temperature variations, are highly vulnerable to thermal losses and structural degradation. Using **glass cloth facings** laminated to closed-cell elastomeric foam insulation provides a high-performance solution that meets strict mechanical and thermal demands.
Glass fiber cloth provides high tensile strength, protecting the underlying elastomeric insulation from tears, punctures, and mechanical wear during installation and regular maintenance. Furthermore, when combined with aluminum foil laminates, it forms a vapor barrier with a near-zero perm rating. This prevents moisture from driving into the insulation layer, eliminating the risk of condensation and sub-insulation corrosion.
Safety is a priority in high-occupancy environments like commercial offices, airports, and hospitals. Glass fiber is naturally non-combustible. When used as a facing, it acts as a fire barrier that meets critical international ratings including BS 476, ASTM E84, and UL94. This combination helps slow flame spread and minimizes smoke density in critical situations.
For MEP contractors, quantity surveyors, and project engineers, selecting insulation materials requires evaluating cost against long-term performance. Key factors include:
Located in Dacheng, China—a hub for green building materials—Kingflex Insulation Co., Ltd. uses automated technology and vertical supply chain integration to maintain reliable production. Our facilities feature five automated assembly lines capable of producing over 600,000 cubic meters annually, helping us meet demand from regional projects and global markets alike.
Integrating Factory 4.0 automation allows for precise control over raw material mixing, density, and cell structure. This ensures consistent quality across every batch of NBR/PVC elastomeric rubber foam sheets and tubes.

Kingflex insulation products are certified to meet international safety and environmental guidelines, facilitating integration into projects globally:
Standard Dimensions:
Key Advantages: Consistent cell structure with a high closed-cell rate (>98%) provides reliable thermal properties and moisture protection. The material self-extinguishes upon fire contact and offers high resistance to moisture migration.
Typical Applications: Insulation for large central air conditioning ducts, multi-story wall and roof assemblies, basement thermal lining, industrial chemical tanks, and cold chain logistics storage.
Standard Dimensions:
Key Advantages: High closed-cell rate (>98%) reduces heat loss, while specialized manufacturing ensures a uniform coating thickness. Highly flexible to fit complex pipe routing, it helps prevent pipe freezing and cracking in cold conditions.
Typical Applications: Chilled water piping, HVAC refrigerant loops, building plumbing freeze protection, industrial process steam systems, and chemical pipeline insulation.
Our insulation systems are used in diverse sectors including civil construction, chemical processing, aerospace, and high-occupancy municipal venues.
For commercial offices, shopping malls, and hospitals, duct networks must prevent condensation that can lead to mold and compromise indoor air quality. Kingflex elastomeric insulation with glass cloth facing provides thermal control and vapor protection, helping keep systems clean and efficient.
In facilities with chemical processing equipment or marine vessels, insulation must withstand physical impact, vibration, and harsh environmental conditions. The glass cloth layer protects the elastomeric foam from physical damage and chemical splashes, maintaining performance over a long service life.
