How Many Building Frames Can a Sapphire Balcony Connect To?

At Sapphire Balconies, we can connect balconies to various building structures, including traditional reinforced concrete (RC) frames, cross-laminated timber (CLT) frames, light gauge steel frames (LGSF), tunnel form structures (TFS), and even Peikko’s DELTABEAM® Frame.   

Leading the market through innovation, we ensure that our balconies meet the unique demands of each structure, providing lightweight options that complement sustainable materials while maintaining strong, safe connections.  

Cross-Laminated Timber Frames   

Cross-laminated timber, or mass timber, is created by glueing together layers of solid-sawn lumber taken from a single log. By glueing the wood layers at the right angles, CLT can achieve better structural rigidity than regular timber in both vertical and horizontal directions.  

Benefits of CLT:   

  1. Improved Project Efficiency: CLT as a prefabricated material is incredibly flexible for building design. Whilst concrete is the conventional option due to its perceived rigidity, some companies favour CLT over concrete as it is 20–30% faster to install and can reduce the need for on-site labour.   
  2. Strong Fire Performance: The fire performance of CLT is exceptional as it is fire-rated and compliant for ongoing use.  

Reinforced Concrete Frames  

A traditional concrete frame is built from the ground up, poured between stacks of rebar steel to create a sturdy wall to the building.   

Thanks to its rigidity, this method is used to this day as a reliable (albeit slower than a precast alternative) way to build apartment blocks and a durable material to anchor a balcony into. However, given how labour- and carbon-intensive this approach is, many countries are looking for more advanced approaches.  

  1. We can connect to a traditionally poured concrete façade in several ways with our lightweight aluminium Cassette® balconies. Their slim, manageable form allows any number of connections to be made.
  2. Using our innovative and speedy solution, we cast the anchors into the concrete slab. This forms a robust base for the balcony Cassette® to slide directly onto, at which stage it is secured by an on-site team.  

Light Gauge Steel Frames  

Light gauge steel frames are a modern solution for low-rise buildings (up to 15 storeys), offering faster construction, cleaner sites, and a reduced carbon footprint. As the name suggests, LGSF is a skeleton of sorts for a building, a dynamic and versatile application that uses lightweight, 100% non-combustible material to provide the inner support for a building whilst staying as green as possible.   

Considerations when connecting balconies to LGSF:  

  1. Due to the lightweight nature of LGSF, balconies should be as light as possible to avoid any instances of deflection. 
  2. With balcony anchors, a key issue is the connection back into the frame, as rotational deflection can occur here. Sapphire has developed new connection methods that provide extra rigidity.   

The DELTABEAM® Frame  

Peikko’s DELTABEAM® is an innovative steel building frame that reduces the number of columns needed in a building. This allows for longer spans of unsupported horizontal beams, giving you more floor area for any given building footprint.  

  1. Sapphire Balconies are able to connect to the DELTABEAM® frame without compromising on thermal performance, installation speed, or cost.   
  2. This solution is suitable for any project as it comes with standard components that don’t require unique costs, technologies, or modifications.   

Connecting balconies to a DELTABEAM® frame previously required a concrete infill, but – thanks to collaboration between Peikko and Sapphire – that’s now a thing of the past.  

We connected balconies to the DELTABEAM® frame at Silvertown Quays in Newham, London.

Tunnel Form Structures  

Tunnel construction is a framework that allows a building contractor or developer to cast walls and concrete slabs at once as part of a daily routine.   

It is one of the many modern methods of construction (MMC) that are now used to increase the speed of projects and the quality of the final result, based on the accuracy that off-site production and storage can provide.  

Connecting balconies to TFS:  

  1. As with standard concrete slabs, tunnel construction cells can be penetrated and thermally guarded on-site to create balcony connection points.  
  2. Because tunnel cells are cast in situ, the balcony connections can be cast with the concrete slab to avoid excess penetration of the slab itself.    

Sapphire’s lightweight balconies can easily connect to TFS.

The general election is well underway and it’s time to address the elephant in the room – Sapphire is exactly what the United Kingdom’s residential construction industry needs at this pivotal moment.

Building a better balcony has been a labour of love for us since founding Sapphire in 1992.

We’re not conservative when sharing our values. In fact, we’ve discussed them openly this past year with publications like Decision Magazine, where Sapphire was noted as a shining example of good company values.

Liberal use of technology has been crucial for Sapphire over the years and we’re pledging to continue excelling in innovative design, balcony systems and installation technology, assisting us in achieving quality, sustainable balcony practices.

We should all be aware of green policies, adhering to Net Zero and Science-Based targets as best as we can. Our Vision 2030 sets out our ESG strategy and our vision to be leaders in the construction industry, driving sustainability and responsible practices.

Reform isn’t what we need when it comes to balcony design – in fact, it’s innovation that matters. Sapphire is making waves with the Next Generation balcony system, and we promise to keep innovating in the years to come.

It’s time for real change in the residential construction sector with Sapphire.

Our ‘Manifesto’

Sapphire isn’t a political party. In fact, the things that set us apart from a political party are exactly what make us perfect for your next development . Let’s take a moment to reflect on how Sapphire stands out in the often-tumultuous world of politics.

Here are the key differences that set us apart from the major political parties in 2024:

We hold ourselves accountable and champion transparency.

Are you tired of a lack of transparency within politics, decisions shrouded in political manoeuvring and rhetoric? With Sapphire, tire no longer. We operate with a high degree of transparency and take accountability seriously. You’ll be in the loop at every step of the process, making the balcony journey as streamlined as possible.

Sapphire is dedicated to innovation in the residential construction market. We continuously seek new ways to improve our services and deliver cutting-edge solutions – whether it’s our Next Generation balcony system, our Remote Locker Device or our Clip-On® connection – we’re always looking forward to what’s next.

We centre the customer in our innovation – eschewing broad ‘electoral’ appeal.

Appealing to everyone can often lead to satisfying no one. Our innovations are driven by the needs of our customers, the needs of our developers and the needs of our architects. Driving specific innovations in each of their areas has led to top-class balcony design and seen truly sustainable improvements in the residential construction market.

We use evidence-based development, never ideological decision-making.

No matter where your political allegiance lies, data must lead the charge when making decisions. Our product development is based on tight engineering principles, adhering to ever-evolving industry standards and feedback from our customers.

We lead by our values – never giving them up.

Sapphire’s leadership is guided by our values, which we never compromise. This ensures our decisions and actions are aligned with our principles, driving our organisation forward with integrity and clear, cohesive goals.

We collaborate with our industry partners to improve standards.

Trying to outwit your opponents may work in a general election, but at Sapphire, we’re honoured to often collaborate with other companies in the construction industry to improve standards and practices and even on product innovation like the Clip-On® connection, seen used at the NE02 development in Wembley Park.

We focus on long-term successes, not short-term gains.

Sapphire is committed to long-term success. We build sustainable solutions that benefit our clients and communities for years to come, focusing on enduring progress rather than short-term wins.

We problem-solve proactively, not reactively.

Policymaking can often be reactive, responding to ongoing crises or public pressure. At Sapphire, we are pleased to be proactive. Our research and development team apply their ongoing learning to address potential issues through design innovation, making sure we’re always one step ahead of the curve.

We operate efficiently, putting bureaucracy to bed.

We’ve seen it plenty of times over. Bureaucracy can stall decision-making. At Sapphire, our design, manufacture, operations and supply are all streamlined by innovation for maximum efficiency, reducing lead times, improving productivity and making your balcony journey straightforward.

If we aren’t right for the job, we’ll tell you.

At the end of the day – honesty and transparency are core principles at Sapphire. We’ll always provide the best advice for your needs, even if it means acknowledging when we’re not the right fit for the job at hand.[/sapphire_textBlock][/vc_column][/vc_row][vc_row width=”70″ background_image=”” order=”Image left / content right” image=”13193″ heading=”Discover Sapphire’s Next Generation Balcony” button_text=”Discover” button_link=”url:http%3A%2F%2Flocalhost%2Fbalconies%2Four-product%2Fthe-next-generation-balcony%2F|title:The%20Next%20Generation%20Balcony”][vc_column][sapphire_contentLink order=”Image left / content right” image=”13193″ heading=”Discover Sapphire’s Next Generation Balcony” button_text=”Discover” button_link=”url:http%3A%2F%2Flocalhost%2Fbalconies%2Four-product%2Fthe-next-generation-balcony%2F|title:The%20Next%20Generation%20Balcony”]The Next Generation Balcony is a huge step forward for the construction market[/sapphire_contentLink][/vc_column][/vc_row][vc_row width=”70″ background_image=””][vc_column][sapphire_textBlock]The choice is clear.
