For architects specifying building envelope solutions, having the right technical partners can make all the difference. ICB Group brings together three specialist companies — ICB Waterproofing, ICB Fabrications and ICB Projects — offering a coordinated approach to flat roofing, metal fabrication and renewable technologies. Together, they provide practical design support, tested systems and CPD learning opportunities to help architects deliver high-performing, compliant and visually refined buildings.
ICB Waterproofing: roofing systems with technical confidence
ICB Waterproofing specialises in flat roofing solutions, particularly high-performance single-ply membranes, reinforced bituminous systems and liquid waterproofing technologies. ICB are the UK’s sole distributor of the alwitra® membrane. These systems are widely specified across commercial, residential, education and healthcare sectors, where durability, fire performance and compliance with evolving regulations are critical.
Architects benefit from early engagement with ICB’s Technical team, who provide specification guidance, build-up advice, drainage detailing support and assistance with meeting regulatory requirements such as fire classification and sustainability targets. Many of the systems offered contribute to green roof, blue roof and bio-solar designs, and solar PV, helping projects meet environmental goals alongside technical performance.
ICB Fabrications: precision metal solutions for modern architecture
Architectural detailing increasingly demands bespoke solutions that balance aesthetics with practicality. ICB Fabrications focuses on aluminium fabrication, including cappings, fascias, soffits, flashings and custom architectural features such as planters, screening and façade elements.
Manufactured in the UK using precision machinery and high-quality finishing processes, these solutions allow architects to achieve clean design lines while ensuring longevity in challenging weather conditions. Aluminium’s corrosion resistance, recyclability and design flexibility make it a strong choice for contemporary projects that prioritise sustainability and visual impact.
Early collaboration with the ICB Fabrications team helps ensure details are buildable, cost-effective and aligned with overall design intent — reducing risk later in the project lifecycle.
ICB Projects: integrated renewable and roofing solutions
As sustainability moves to the centre of building design, ICB Projects supports architects with solar PV integration, green roof systems, rooflights, ventilation solutions and associated mounting technologies. The focus is on combining energy generation, daylighting and environmental performance with practical installation considerations.
Whether designing a retrofit scheme or a new build targeting net zero operational carbon, architects can access technical advice on system compatibility, structural considerations and integration with waterproofing layers — ensuring performance without compromising design.
CPD opportunities for architects
Alongside products and services, the ICB Group offers RIBA-approved CPD sessions tailored specifically for architects and specifiers. These typically cover topics such as flat roofing design, green and blue roof systems, solar PV integration, metal detailing and regulatory compliance. These hour-long sessions can be booked via the website and include a free breakfast, or lunch.
A collaborative partner for specification success
By combining waterproofing expertise, precision fabrication capabilities and renewable technology solutions, the ICB Group provides architects with a joined-up approach to building envelope design. From early concept advice through to specification support and ongoing technical guidance, the aim is simple: to help architects deliver buildings that perform well, meet compliance requirements and stand the test of time.
