NON-PENETRATIVE Balcony & Balustrade Systems
Designed, Supplied & Installed with Comprehensive Structural Reports
By eliminating surface penetrations, these systems prevent water ingress and mitigate the risk of thermal bridging, protecting the building envelope, preserving insulation performance and offering a compliant alternative to traditional balustrade fixings
What Are Non-Penetrative Balustrade & Balcony Systems?
Non-penetrative systems create stable balustrades and balcony structures using purpose-designed support frames or base plates that distribute loads across the surface rather than anchoring through it. This protects the underlying waterproof layers and eliminates the risk of leaks while delivering full structural performance suitable for residential and commercial applications.
These systems are engineered to meet wind and static load requirements without compromising the roof or deck surface.
Typical uses include:
Flat roof terraces
Waterproofed balconies
Apartment podium decks
Commercial roof decks
Retrofit balcony installations
Benefits of Non-Penetrative Balustrade & Balcony Systems
1. Waterproof Membrane Protection
No drilling means the waterproof layer remains intact, reducing the risk of leaks and damage.
2. Ideal For Retrofit Projects
Where existing waterproofing warranties would be voided by penetrative fixings.
3. Fast, Clean Installation
No need for core drills or intrusive fixings, making installation quicker and less disruptive.
4. Engineered Structural Performance
When correctly designed, these systems meet all required load standards and building regulations.
5. Reduced Long-Term Maintenance
Protecting the membrane from penetration helps avoid future repairs or water ingress issues.
How Non-Penetrative Balustrade & Balcony Systems Are Installed
Site Survey & Assessment
Every project begins with a full survey to assess substrate type, deck finish and structural conditions.
Engineered Calculations
Structural engineers calculate loadings and design a system specific to the environment and building standard requirements.
System Fabrication
Support bases and frames are manufactured to spec with precision.
Installation
Frames or base plates are set into position, balanced and secured in line with design drawings. The balustrade or balcony structure is then assembled onto this support.
Why Structural Calculations & LABC Compliance Matter
Non-penetrative systems must be supported by certified structural engineering reports and calculations. This documentation is essential to demonstrate compliance with:
- Building regulations
- Local Authority Building Control (LABC) standards
- Load capacity and safety requirements
Installing without proper calculations can lead to failed inspections, remedial costs and compromised safety.
Always confirm that the specialist you choose includes comprehensive structural reports as part of their service.
Choose the Right Specialist
A reputable installer like 360 GSS, will provide a detailed site assessment, engineering-backed design, precision fabrication, professional installation and full compliance documentation. Choosing experienced professionals ensures your system is safe, compliant and built to last.

We manufacture bespoke non-penetrative balustrade & balcony sytems using high-quality steel and corrosion-resistant finishes as standard.
All projects are backed by comprehensive engineer calculations and reports bespoke to your property, providing confidence that your installation is designed for long-term performance, structural integrity and thermal efficiency.
FREQUENTLY ASKED QUESTIONS
What are non-penetrative balustrade & balcony systems?
They are structural systems designed to support balustrades and balconies without drilling through the waterproof membrane of a roof or deck.
How do non-penetrative systems work?
Load is distributed via engineered base plates and frames that sit on the surface rather than fixed through it.
Where are these systems typically used?
Commonly on flat roofs, terraces, waterproofed balconies and podium decks where membrane integrity must be preserved.
Are non-penetrative systems compliant with UK building regulations?
Yes, when installed with full structural engineering reports and engineered calculations to demonstrate compliance.
Do I need planning permission for a non-penetrative balcony system?
It depends on height, location and property type. Lower level systems may fall under permitted development; others may need planning consent.
Can non-penetrative systems be retrofitted?
Yes, they are ideal for retrofit projects where existing waterproofing cannot be compromised.
Do non-penetrative balustrades leak?
Properly engineered non-penetrative systems protect the waterproof membrane and significantly mitigate the risk of leaks.
What is the installation process like?
A survey and structural design are followed by fabrication and secure placement of the support system and final assembly.
What should I look for in a specialist installer?
They are essential for demonstrating load compliance and for approval by building control authorities such as LABC.
