System Performance & Vapour Barriers

Glass cloth facing acts as a high-tensile, puncture-resistant membrane that prevents physical degradation in HVAC systems. Used alongside closed-cell elastomeric rubber foam or mineral fibers, it provides critical vapor sealing to combat condensation and thermal bridging.

🛡️

Acoustic Attenuation & Structural Integrity

High-density weave configurations dampen turbulent duct acoustics. When paired with open-cell soundproofing cores, the glass cloth shell stabilizes air-facing paths, protecting internal fibers from delamination at high velocities.

🔥

Fire Protection Compliance

Woven fiberglass composites resist temperatures beyond typical building requirements. Combined with Class 0 and Class 1 elastomeric foundations, glass cloth systems meet strict BS 476 and UL 94 safety requirements.

Technology Roadmap & Macro-Industry Solutions

Supporting advanced industrial processes, sub-zero logistics, and sustainable building systems.

1. Cryogenic and Ultra-Low Temperature Solutions

Extreme cooling systems demand insulation that resists moisture ingress. Our elastomeric cryogenic configurations prevent freezing in liquefied gas lines and cleanroom HVAC networks.

Cryogenic System Testing

2. High-Performance Architectural Integration

Large infrastructure projects require insulation with consistent thermal performance. Our materials reduce thermal bridging in structural envelopes, helping projects meet modern efficiency standards.

Architectural Insulation Layout

3. Industrial Ductwork Cladding and Safety

Exposed air distribution channels in factories face high wear. Applying glass-cloth facing creates a hard shell that resists abrasion, moisture ingress, and ambient heat transfers.

Ductwork Cladding Process

Factory 4.0 Precision

Our facility runs five automated manufacturing lines. Automated temperature tracking ensures consistent density and cell structure throughout production.

Frequently Asked Questions (FAQ)

Direct answers regarding specifications, materials testing, and implementation protocols.

Q1: What is elastomeric rubber foam insulation used for?
A1: It is primarily used for HVAC air ducts, building envelope thermal protection, industrial plant steam piping, chilled water lines, and acoustic dampening across industrial and commercial facilities.
Q2: Is Kingflex rubber foam insulation fire resistant?
A2: Yes, our elastomeric compounds incorporate specialized flame retardants. Our products meet global fire safety standards, achieving ratings like Class 0 and Class 1 under BS 476.
Q3: What is the difference between rubber foam and rock wool insulation?
A3: Elastomeric rubber foam features a flexible, closed-cell structure that resists moisture ingress, making it suitable for chilled applications. Rock wool is a fibrous mineral material that handles higher service temperatures, making it ideal for industrial boilers and exhaust runs.
Q4: Do you provide customized insulation products?
A4: Yes, we provide full OEM and ODM services. We customize thickness, density, core material, backing adhesives, and outer coatings like glass cloth or aluminum foil to match project specifications.
Q5: What certifications do your products have?
A5: Our products are certified under BS 476, CE, REACH, RoHS, UL94, and ASTM. Testing is performed by third-party laboratories to verify performance compliance for regulatory approvals.
Q6: Do Kingflex products have traceability?
A6: Yes, each batch is assigned a unique production run code, allowing us to trace manufacturing parameters, raw material inputs, and quality checks.
Q7: What thickness of Rubber foam insulation sheet roll can you produce?
A7: Our standard extrusion lines produce continuous sheet rolls in thicknesses ranging from 6mm to 50mm, accommodating various thermal design specifications.
Q8: What is the service life of rubber plastic pipe and board?
A8: Under standard operating conditions and with proper installation, our materials provide a service life of 10 to 15 years.
