TruPlas® Spacer Bar

Key Benefits of TruPlas

• Rigid GRP spacer for stability and strength; ridged, traditional edge aesthetic with a matte finish and sharp 90° corners for straight-line application.
• 8× more perforations support cleaner production and help prevent hot-melt butyl “blowing out” in the corners.
• Dual-seal system with multi-layer vapour barrier to support gas retention and long-term durability.
• Low thermal conductivity helps reduce perimeter condensation for improved comfort and sightline appearance.
• No chemical fogging performance (meets EN 1279-6).
• EN 1279-2/-3/-6 performance; very good UV resistance and wide high/low temperature tolerance.
• Works with traditional cut-and-key; specialised heated bar-bending available for volume lines.

Why Choose a TruPlas Thermoplastic Spacer?

• Very good UV resistance with excellent high and low-temperature performance.
• 8× more perforations than other rigid spacers prevents HMB “blowing out” in the corners.
• Complete range of keys available for cut-and-key and Georgian applications.
• Uses a proven vapour barrier with an advanced acrylic that strengthens under heat.
• TruPlas passes EN 1279 Parts 2, 3 & 6 and achieves no chemical fogging (EN 1279-6).
• Low thermal conductivity for substantially reduced perimeter condensation.
• ISO 9001 Accreditation.

TruPlas SDL Thermoplastic System

TruPlas SDL is a glass reinforced thermoplastic bar and clip system designed to outperform traditional SDL products. TruPlas SDL creates an authentic multi-panel effect within a single insulating glass unit.

Available in black, white and grey, TruPlas SDL uses a bar and clip system that is compatible with all rigid and flexible spacer bars using a range of clip options. These include:

• Cruciform Clips
  TruPlas SDL cruciform clips use a specially designed anchoring system to ensure the clip stays securely in the bar to guarantee squareness of the grid.
• Super Spacer Manual Clips
  TruPlas SDL Super Spacer manual clips have an offset fin which is trapped between the spacer and glass interface to secure and square the bar in the airspace of the grid.
• Rigid Spacer Staple Clips
  TruPlas SDL rigid spacer staple clips use a specially designed anchoring system, ensuring that the clip will stay securely in any rigid spacer.
• Super Spacer Automatic Clips
  TruPlas SDL Super Spacer auto clips offer quick secure placement into pre-notched locations in the spacer to assure grid accuracy and stability.

TruPlas® vs Other Rigid Warm Edge Spacers

TruPlas® is designed to make production cleaner and more predictable while delivering a traditional look that many customers recognise and prefer. Compared with typical rigid warm edge spacers, TruPlas® offers:

• 8× more perforations to improve airflow and help prevent HMB corner “blow-out”.
• A proven multi-layer vapour barrier with an advanced acrylic that strengthens under heat.
• No investment needed for traditional cut-and-key processing (with optional heated bar-bending for higher output).
• EN 1279 Parts 2, 3 & 6 performance, no chemical fogging, low thermal conductivity and very good UV/temperature resistance.

Applications & Processing

TruPlas® drops into established cut-and-key workflows for IGU manufacture, with a complete range of keys and plugs for standard and Georgian grids. For higher-volume production, specialist heated bar-bending machinery is available to automate frame forming and increase throughput while maintaining neat, repeatable corners.
