Unitised Facade Systems
Contact UsAt Facade Systems, we supply, design, and install unitised facade systems and across the UK, helping developers and architects create high-performance, precision-engineered exterior envelope solutions. Our technical specialists engineer modular wall units that offer superior component quality and rapid site integration compared to traditional stick-built methods.
By synthesising advanced off-site fabrication with rigorous safety protocols, we ensure every multi-storey project achieves a thermally efficient and weathertight building skin that meets current UK building safety legislation.
What Are Unitised Facade Systems And Why Are They Used In Modern Buildings In ?
In , unitised facade systems are factory-assembled building envelopes comprising floor-to-floor panels that integrate glazing, framing, and insulation into a single modular unit. These systems are utilised because controlled factory assembly ensures more consistent weathertight joint performance and significantly reduces on-site labour dependency.
By implementing these precision-engineered modules, developers can achieve an accelerated construction programme, allowing the building to be dried in faster and facilitating earlier interior fit-out cycles for high-rise developments.
How Much Do Unitised Facade Systems Cost In ?
The cost of unitised facade systems ranges from £500 to over £1,200 per square metre, depending on the panel dimensions, glazing specification, and structural complexity of the building.
Costs are primarily influenced by the repetition of floor-to-floor heights, the requirement for bespoke mullion and transom profiles, the selection of high-performance acoustic or solar glass, and the logistical demands of cranage and site access for large-scale panel delivery.

What Services Are Provided For Building Exterior Solutions In ?
We deliver a comprehensive suite of professional services designed to support the entire lifecycle of your modular building envelope, including:
System engineering and design – Developing detailed CAD layouts and structural calculations to ensure the units accommodate building movement and wind loads.
Factory fabrication and assembly – Manufacturing complete floor-to-floor units in a controlled environment to guarantee high-fidelity quality control.
Professional modular installation – Executing sequential unit mounting using bespoke bracket systems anchored to structural floor slabs for maximum site safety.
Performance validation testing – Conducting rigorous audits of air permeability and water tightness to verify the integrity of the pressure-equalised joints.
Post-completion technical care – Providing documented compliance certification and long-term maintenance guidance to preserve the performance of the building skin.
Where Are Unitised Facade Systems Commonly Installed On Buildings In ?
High-occupancy and high-rise structures frequently feature unitised facade systems to provide a consistent and high-quality exterior finish across large surface areas. These systems are most commonly integrated into commercial office towers and high-specification residential apartment blocks where the speed of floor-by-floor enclosure is a critical project requirement.
By applying these modules to complex curved or angled geometries, developers ensure a level of geometric precision that is unachievable through site-based construction, resulting in a seamless architectural elevation.
When Should Developers Choose Unitised Facade Systems Over Stick-Built Methods In ?
Specifying unitised facade systems is the optimal strategy when a project involves significant height or repetitive facade geometry that demands programme certainty. Developers should opt for these modular systems during the early planning phase to mitigate the risks associated with adverse weather and limited site storage space.
This selection is increasingly vital for urban city-centre projects, where reducing the duration of external scaffolding and on-site labour significantly lowers the overall project risk and enhances site safety.
How Do Unitised Facade Systems Function As A High-Performance Building Skin In ?
Operationally, unitised facade systems work by interlocking factory-assembled units using male and female pressure-equalised joint profiles. This principle creates a continuous weathertight seal between adjacent panels, using the cavity to equalise air pressure and eliminate the force that drives water penetration through joints.
The system utilises a combination of mechanical bracket anchors and precision gaskets to accommodate structural floor deflections while maintaining the building's thermal integrity and acoustic barrier.
What Types Of Unitised Facade Systems Are Available For Buildings In ?
We provide several configurations of unitised facade systems designed to satisfy varying architectural styles and environmental performance requirements, including:
Fully glazed curtain walls – High-transparency aluminium-framed units ideal for providing natural light and high aesthetic finishes to corporate offices.
Mixed glazing and cladding tiers – Modular units incorporating opaque spandrel zones to conceal floor slabs and building services.
Double-skin buffer systems – Advanced assemblies featuring inner and outer glazed layers that create a ventilated thermal zone for superior energy efficiency.
Integrated solar shading modules – Units with pre-fitted brise soleil or louvres designed to modulate solar gain and reduce internal cooling loads.
Bespoke geometric configurations – Tailored unit designs created for landmark buildings with complex facets, slopes, or three-dimensional geometries.
How Durable And Weather Resistant Are Unitised Facade Systems In ?
The longevity of unitised facade systems is underpinned by factory-controlled assembly, which eliminates the workmanship variability often found in site-built structures. When finished with high-performance PVDF or powder coatings, the aluminium framing resists atmospheric corrosion and UV degradation for over forty years.
This resilience ensures that the building envelope remains impermeable to environmental stressors, protecting the internal structure and reducing the requirement for expensive reactive maintenance interventions.
Which Industries and Building Types Rely On Unitised Facade Systems In ?
A wide array of professional and public sectors rely on unitised facade systems to maintain high-traffic efficiency and safety compliance, featuring:
Healthcare and NHS trusts – Delivering hygienic and durable envelopes for multi-storey hospitals requiring fast project turnaround.
Commercial hospitality groups – Ensuring hotel exteriors reflect premium branding while providing guests with enhanced acoustic insulation.
Higher education facilities – Creating inspiring architectural landmarks for universities that withstand environmental exposure and student use.
Mixed-use residential towers – Improving the safety and thermal comfort of multi-occupancy blocks through non-combustible modular cladding.
Transport and civic hubs – Engineering robust, weather-resistant skins for airports and railway terminals that require exceptional structural performance.
What Safety Standards And Building Regulations Must Unitised Facade Systems Satisfy In ?
Compliance with BS EN 13830 is the technical benchmark for all unitised facade systems to ensure structural resistance and water tightness. Following the Building Safety Act 2022, any system applied to buildings over 11 or 18 metres must achieve an A1 or A2-s1, d0 fire rating to prevent external flame spread.
Our engineering team verifies every system against Approved Document B, providing developers with the mandatory safety certification required for regulatory building control sign-off and insurance validity.
