The YSHIELD® SAFEBUILD® U230 shielding underlay membrane is a high-performance solution for versatile electromagnetic shielding applications. This premium four-layer membrane features a micro-needled aluminum foil layer with 200,000 tiny holes per square meter, providing optimal water vapor permeability while delivering exceptional shielding efficiency. With an attenuation of 111 dB measured from 600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006. the U230 is ideal for use in roofs, facades, and drywall constructions. The membrane effectively blocks high-frequency (HF) and low-frequency (LF) electromagnetic fields, making it perfect for both professional and private use. Designed for easy installation, it is recommended to use YSHIELD® PSA – Pressure Sensitive Adhesive for bonding, ensuring a secure and long-lasting application.

Use:

• Exterior Use:
  • Roofs: Provides effective shielding while optimizing wind tightness and preventing rain penetration.
  • Facades: Protects against the penetration of warm air in summer and cold air in winter.
• Interior Use:
  • Drywall Constructions: Can be applied as an underlay membrane for additional shielding.
  • Walls: Suitable for use as intermediate wallpaper or directly onto walls for added protection.
  • Ceilings: Can be applied to ceilings to enhance overall shielding in a room.

Processing Instructions:

• Apply the underlay membrane overlapping, without gaps, and keep holes for fastening as small as possible.
• The aluminum side should always face inward to prevent corrosion, and the brand imprint should be visible.
• For optimal bonding and ease of installation, we highly recommend using YSHIELD® PSA – Pressure Sensitive Adhesive or either Conductive/Non-Conductive tape. Ensure that the chosen adhesive meets your specific setup requirements.
• The aluminum side must be grounded. Use GSX grounding strips on the silver side for effective grounding.
