Non-Penetrative Balustrade & Balcony Systems

labc compliant structural calculations & reports

Structural stability without compromisE

Non-penetrative balustrade systems are designed for modern balcony and terrace construction where waterproofing performance, thermal efficiency and structural integrity are critical. Traditional top-fixed systems often require penetrations through roofing membranes and insulated build-ups, increasing the risk of water ingress and thermal bridging over time.

360 GSS designs, supplies and installs bespoke non-penetrative balustrade and balcony systems engineered to avoid unnecessary surface penetration while still delivering the required structural performance. Every system is tailored around the specific substrate, loading requirements and architectural intent of the project.

This approach is particularly effective for flat roofs, podium decks, terraces and insulated balcony structures where protecting waterproofing layers and reducing cold bridging is a priority.

Glass, Steel & Structural Specifications

All non-penetrative balustrade systems are designed, fabricated, supplied and installed to meet both structural and architectural requirements:

  • Toughened laminated safety glass engineered for strength, compliance and long-term durability
  • Ultra low iron glass available for enhanced clarity and reduced green tint
  • Clear, frosted, acid etched, sandblasted, tinted and coloured glass options available
  • Structural steelwork fabricated in-house to suit the exact loading and fixing requirements of the project
  • Steel support systems available galvanised, powder-coated or finished to project specification
  • Designed to help reduce penetrations through waterproofed surfaces and minimise thermal bridging risks
  • Manufactured and installed with awareness of LABC guidance and relevant British Standards regulations

Engineered for Modern External Structures

A non-penetrative balustrade system must do more than provide edge protection. It needs to work alongside modern construction methods, waterproofing systems and insulated structural build-ups.

Our bespoke systems are designed to:

  • Help maintain the integrity of waterproofed roof terraces, balconies and external structures
  • Reduce the risk of thermal bridging caused by traditional penetrative fixing methods
  • Meet structural and safety requirements for residential and commercial projects
  • Provide stable, long-term edge protection with minimal visual impact
  • Integrate cleanly with modern architectural glazing and external build-ups
  • Deliver long-term durability with minimal maintenance requirements
