6A–27A Hybrid Fiberglass Warm Edge Spacer Bar, Hollow Metal Laminate, Energy-Saving for Double Glazing IGU

Product Overview

Upgrade your insulating glass units with our glass fiber reinforced warm edge spacer bar — the smart choice for manufacturers who demand superior thermal performance and long-term reliability. Made from high-performance ABS+30% glass fiber composite with a multi-layer dense vapor barrier film, this completely non-metallic spacer delivers ultra-low thermal conductivity of just λeq=0.16 W/(m·K). It effectively blocks heat transfer at the glass edge, reduces condensation, prevents mold growth, and keeps your IGUs crystal clear for years. Certified by ift Rosenheim to EN1279 standards and compliant with EU RoHS (SGS tested), it's the ideal solution for passive house projects and energy-efficient buildings.
Advanced Manufacturing & Quality Control
Every spacer bar we produce undergoes rigorous manufacturing and quality inspection processes to ensure you receive only the best. Here's what sets our quality apart:
  • Precision extruded ABS+30% glass fiber composite​ for consistent strength, stability, and thermal performance batch after batch
  • Multi-layer dense vapor barrier film​ on the back for superior moisture resistance and long-term sealing durability
  • Uniform vent hole distribution​ engineered for optimal desiccant exposure and efficient moisture absorption
  • Smooth, scratch-free surface​ with consistent color for a clean, professional finish on every project
  • Tight dimensional tolerances​ (±0.15mm width, +0.2/-0mm height) guaranteeing leak-proof corner assembly and trouble-free production line integration
  • Certified by ift Rosenheim​ according to EN1279-2/3/6 and compliant with JC/T 2453-2018 standards
Your reputation depends on quality — we make sure you never have to compromise.
Key Features & Benefits
 
Ultra-low thermal conductivity for superior energy savings
With an equivalent thermal conductivity of only λeq=0.16 W/(m·K), this completely non-metallic spacer dramatically outperforms traditional aluminum spacers. Your end users enjoy lower energy bills, warmer interior surfaces in winter, and more comfortable indoor temperatures — making it the best choice for passive houses and near-zero energy buildings.
 
Say goodbye to condensation and mold
By minimizing heat loss at the glass edge, this spacer significantly raises the interior surface temperature of the glass. The result? Less condensation, reduced risk of mold growth, and healthier indoor living environments that impress your customers.
 
Proven durability you can trust
Tested and certified by ift Rosenheim according to EN1279-2 (durability), EN1279-3 (argon gas retention), and EN1279-6 (chemical fogging). Also passes UV radiation resistance tests (3000h with no significant color change) and meets EU RoHS requirements verified by SGS. Built to perform in any climate.
 
Easy processing for any window profile
Excellent flatness (<0.01% straightness deviation) and low distortion values (<0.02mm) make these spacers easy to handle on automated production lines. Compatible with corner insertion, welding, and heated bending processes — giving you flexibility for custom complex window shapes without structural damage.
Broad sealant compatibility
Works seamlessly with polysulfide, silicone, silicone structural, and butyl sealants — no compatibility concerns during production.
