GLASS TERRACE BALCONY

CHALLENGE OVERVIEW:

Upon our team's arrival at a development site in Twyford, 360 GSS was confronted with a complex problem. The site featured an unfinished parapet wall that encircled an area with exposed roof joists. This space was intended to serve as a terrace balcony, but an oversight in the architectural planning had left it without the necessary structural support for the envisioned frameless glass balustrade. Moreover, the area we would soon allocate for a steel subframe, crucial for mounting a glass balcony, was exceedingly limited, complicating the project further.

STRATEGIC APPROACH:

In response to this challenge, 360 GSS employed our extensive knowledge in structural engineering to craft a bespoke solution. We proposed the creation of a low-profile, freestanding subframe designed to navigate the spatial constraints and support requirements effectively.

A key consideration in our approach was the adherence to strict building codes, particularly concerning the construction's thermal efficiency, water retention and the minimisation of roof profile. To address these concerns, we recommended the application of a hot melt waterproof membrane combined with high-performance tapered insulation. This innovative solution not only ensured compliance with thermal regulations but also allowed for a more streamlined roof construction, paving the way for the installation of the freestanding frame.

FABRICATION OF A STEEL SUB FRAME:

360 GSS undertook a meticulous engineering process to design and fabricate a galvanised, low profile steel subframe, specifically tailored for installation atop the roof terrace. This innovative approach marked a significant departure from traditional installation methodologies, which typically involve anchoring structures directly into the brickwork or roofing membrane. By opting for a design that allows the subframe to rest on the roof terrace without any penetration into the underlying structures, 360 GSS effectively further mitigated the risk of water ingress and thermal bridging.

INSTALLATION OF FRAMELESS GLASS BALUSTRADES:

In the process of securing the glass panels to the structure, 360 GSS uses aluminium channels that are strategically  bolted into the galvanised steel sub frame, creating a robust foundation for the glass installation. Following this preparatory step, frameless glass panels—each one toughened and laminated to meet the highest standards of durability and safety—were expertly clamped to these aluminium channels.

This method ensured that each glass panel was securely affixed to the structure while maintaining the aesthetic elegance of the frameless design. The use of toughened and laminated glass was a deliberate choice, aimed at enhancing the resilience of the balustrade system against impacts and environmental stresses, thereby safeguarding the well-being of occupants and visitors alike.

COMPOSITE DECKING:

When selecting materials for the terrace flooring, 360 GSS opted for composite decking on non compostable joists, a choice driven by its high quality and durability. This material was specifically chosen to complement the contemporary aesthetic of the frameless glass balustrade, ensuring a cohesive and modern finish to the outdoor space. Beyond its visual appeal, composite decking is renowned for its longevity and minimal maintenance requirements, making it an ideal solution for high-traffic areas exposed to the elements.

RESULTS:

The Twyford terrace balcony project stands as a testament to 360 GSS's expertise in addressing complex architectural challenges through innovative solutions. The successful integration of a low-profile freestanding subframe, a meticulously designed glass balustrade system, and high-quality terrace flooring demonstrates our commitment to excellence in design, functionality, and safety. This project highlights our ability to transform challenging spaces into architectural marvels, exceeding client expectations and setting new standards in the industry.
