NEXUS XI®
The range of NEXUS XI® brick-faced support systems is a joint venture from Leviat and Ibstock. Together, we bring our technical and manufacturing expertise to provide you with lintels and soffit systems that realise your architectural vision, by helping to bring depth and dynamism to your project.
NEXUS XI® brick-faced soffit and lintel systems
NEXUS XI® provides an innovative mechanically fixed suspended brickwork soffit & lintel solution.
NEXUS XI® has a Reaction to Fire classification of A2-s-1,d0 as stated in the BBA certificate, meaning it can be specified and installed with confidence on high-rise buildings over 11 meters, in compliance with building regulations in all UK home nations.
One of the major issues facing our industry today is fire safety, and companies such as ours, industry organisations and legislators are continually looking to develop new, innovative solutions to make the world a safer place.
At Ibstock and Leviat we want to do ‘the right thing’ - our sense of responsibility stretches not just to our customers but to all those who encounter our work.
So when faced with challenges such as major changes in legislation, we see this not as an obstacle to overcome but as an opportunity to improve our product offering.
On 1st June 2022 `Approved document B: Fire Safety - Volume 1 & 2’ was amended, with a direction that all materials used for cladding on residential buildings above 11 metres in the UK must be of `limited combustibility’. Within this guidance, allowed materials are those classed as A1 or A2s1d0 under the European Classification system.
It was these changes that led us to develop our world leading mechanically-fixed NEXUS XI® soffit and lintel solution.
The system comprises a stainless steel soffit tray or lintel with a semi-flexible bedding agent retained in the system to reduce vibration between the stainless steel and brick slip, securing a fire rating of A2-s1,d0.
Alongside its key safety credentials, NEXUS XI® packs a number of other primary benefits, including:
- Quicker to install - no mechanical lifting
- 70% lighter on average than precast alternatives
- Simply lift into position
- Design and prefabricated to fit any size or shape soffit
- Any brick type and bond pattern can be accommodated
- Increase your project's pre-manufactured value with this offsite solution
- Suitable for buildings over 11m high
- Two part system allows full adjustment for perfect alignment
- BBA Approved for any building height
For ultimate durability, NEXUS XI® has been engineered as a mechanical fix solution. This means that each individual brick on the suspended brickwork system is held in place using a combination of innovative fixing methods.

NEXUS XI® brick-faced lintels
NEXUS XI® brick-faced lintels are designed to carry a single leaf of a cavity wall. Prefabricated from stainless steel for maximum corrosion protection, they offer a quick and simple way of creating deep soffits above window and door openings.
They are ideal where speed is important – the permanently bonded brick slips, applied offsite, are manufactured from the same batch as the main brickwork providing a seamless blend meaning no compromise on quality or appearance. The lightweight design means the lintels can be simply lifted into place by hand, with no mechanical lifting equipment required, saving time on site.
- Manufactured offsite
- Lightweight, one-piece design - simply lift into place
- Designed to suit a variety of spans and loads
- Variable face and soffit depths available
