Curtain walling encompasses various types, including:
Each offers unique design and construction features that cater to diverse cladding and glazing requirements.
Stick curtain walling involves the on-site assembly of aluminium mullions and transoms, allowing for versatile facade construction and efficient installation processes.
This construction methodology offers flexibility in design by enabling the use of varying glass types and materials, contributing to visually striking architectural appearances. The structural support of stick curtain walling relies on the precise alignment and anchoring of the aluminium components to ensure a secure and durable installation.
The integration of aluminium materials in stick curtain walling facilitates lightweight yet resilient structures, enhancing the overall functionality and aesthetic appeal of modern building facades.
Unitised curtain walling features pre-assembled units that offer enhanced energy efficiency and superior weather resistance, streamlining the construction process and optimising performance.
These pre-assembled units are designed to fit seamlessly together, reducing the need for extensive on-site construction and minimising installation time. The modular design allows for easier customisation and flexibility in accommodating different building configurations. By utilising lightweight materials and efficient installation techniques, unitised curtain walling contributes to overall construction efficiency and cost-effectiveness.
The precise engineering of unitised systems ensures tighter seals and greater insulation, resulting in significant energy savings and improved building sustainability.
Semi-unitised curtain walling combines on-site assembly with pre-assembled units, offering a balanced approach that facilitates construction, glazing integration, and future maintenance requirements.
This approach maximises construction efficiency by streamlining installation processes while providing flexibility for integrating different glazing systems. It addresses the vital aspect of future maintenance, allowing access to individual units for repairs or replacements without disrupting the entire facade.
The cohesive combination of construction, glazing integration, and maintenance considerations makes semi-unitised curtain walling a preferred choice for modern architectural designs.
Curtain walling utilises a variety of materials to achieve diverse cladding and glazing solutions that contribute to the aesthetic and structural integrity of buildings.
Aluminium is a widely used material in curtain walling due to its lightweight construction, energy-efficient properties, and sustainable attributes, contributing to the modernisation and sustainability of building envelopes.
Its lightweight nature makes it easy to handle during construction, reducing labour costs and making installation more efficient. Aluminium’s energy-efficient properties support better insulation and climate control within buildings, contributing to reduced energy consumption and lower utility costs.
The sustainability of aluminium lies in its recyclability, allowing for the creation of a closed-loop system that reduces the environmental impact of construction projects while promoting a circular economy.
Glass is a prominent material in curtain walling, offering structural support, innovative design possibilities, and enhancing the aesthetic appeal of modern architectural facades.
Designers and architects appreciate the versatility of glass in creating visually striking buildings with an emphasis on transparency and light.
The use of toughened glass in shopfronts and curtain walling allows for seamless integration of indoor and outdoor spaces, whilst the reflective and translucent qualities of glass can introduce a dynamic element to the overall aesthetic of a structure.
This design flexibility enables architects to play with light, reflection, and visual depth, contributing to the creation of architectural masterpieces that capture the essence of modern design and aesthetics.
Steel is used in curtain walling for its exceptional structural integrity, durability, and weather-resistant properties, providing strong support and long-term performance for building facades.
The durability of steel in curtain walling is evident through its ability to withstand harsh weather conditions, corrosion, and environmental exposure. Its robustness ensures that the building facade remains strong and resilient over the years, requiring minimal maintenance.
The weather resistance of steel in curtain walling offers protection against moisture and UV exposure, contributing to the longevity and aesthetic appeal of the structure. These qualities make steel an ideal choice for architects and builders seeking durable and reliable solutions for modern building exteriors.
Stone is utilised in curtain walling to enhance aesthetics, introduce natural light dynamics, and offer durable, low-maintenance solutions for architectural facades.
Its natural variability provides a unique, organic appeal that complements any architectural style, whilst its durability ensures longevity with minimal upkeep.
By allowing natural light to filter through, stone curtain walling creates a warm and inviting atmosphere inside buildings, reducing the need for artificial lighting and contributing to energy efficiency.
The low-maintenance properties of stone make it an attractive choice for architects and building owners, as it requires minimal cleaning and upkeep to preserve its timeless beauty.
Terracotta is an ideal material for curtain walling cladding, offering effective insulation, ventilation, and architectural charm, contributing to energy efficiency and aesthetic appeal.
Its natural properties make terracotta an ideal choice for providing thermal insulation, helping to regulate indoor temperatures and reduce energy consumption. Terracotta’s porous nature allows for efficient ventilation, facilitating air circulation and maintaining a healthy indoor environment.
These features not only enhance the sustainability of buildings but also add a timeless elegance to their exteriors, making terracotta a versatile and sought-after option for modern architectural designs.
Curtain walling offers numerous benefits making it a compelling choice for modern architectural designs and building envelopes.
We have listed some of the advantages of curtain walls below.
The aesthetic appeal of curtain walling contributes to the modern architectural landscape, promoting urban development and enriching building facades with visually striking and contemporary design elements.

Well-defined project timelines help in managing resources effectively and meeting client expectations, ultimately contributing to the overall success of the maintenance and repair projects.
The difference between curtain walling and cladding is that curtain wall systems envelop entire buildings, while cladding serves as the outer protective layer.
No inherent superiority exists; it depends on specific requirements.
Curtain wall systems serve as non-structural cladding and are applied externally on buildings.
Curtain walls usually feature a lightweight aluminium frame and support glazed or opaque panels, commonly referred to as glazing, irrespective of the material used.
The cost of curtain walling varies based on factors like materials, size, and complexity.
It’s generally considered a significant investment in building construction, with expenses influenced by specific project requirements.
The British Standard for curtain walling is BS EN 13830:2016.
This standard specifies the product performance requirements, including resistance to wind load, impact, and other relevant criteria.
