Offering guarantees up to 40 years and high levels of customer service, CA Building Products are one of the UK’s leading manufacturers of cladding solutions. A “one stop shop” for all aspects of roof and wall cladding systems and bespoke fabrications that meet the design and installation requirements of specifiers, contractors and clients.

Twin-Therm® Built Up Roof and Wall Cladding System on installation is both Non-Fragile and fully walkable for the duration of its guaranteed life. Twin-Therm® delivers U-values as low as 0.14W/m²K, by increasing the depth of construction without the need for additional components and air permeability tests on buildings featuring the system have measured as low as 0.33m³/hr.m². Twin-Therm® comes with a full system guarantee of up to 40 years. The entire system, and not only its constituent parts, has been independently verified and carries Agrément certification and the Loss Prevention Certification Board (LPCB) accreditation.

Twin-Therm® Quantum is a self-curved roof design running from gutter to gutter. It incorporates all of the features and benefits of the standard Twin-Therm® system plus the added benefit of lower apex heights over a standard curved roof.

Twin-Therm® Griffon® uses the principles of the Twin-Therm® Quantum’s self-curved design across the apex of the roof to achieve the required external sheet end lap either side of apex. Once at the required end lap pitch, it flows into a straight pitch design with every end lap thereafter being set at the same pitch.

Twin-Therm® Chronus® ‘Chill Stores' are a common use for steel framed buildings. A typical internal temperature of a 'Chill Store' starts at 0-2°C up to 5-8°C. To achieve these figures air tightness of the structure is vital. The Twin-Therm® Chronus specification is an enhanced version of the market leading Twin-Therm® Roof & Wall Cladding system. Twin-Therm® Chronus is specially designed to meet 'Chill Store' requirements.

River-Therm® Secret Fix Roof and Wall Cladding System is a built-up, site assembled secret fix roofing system with a unique geometric locking action allowing for foot pressure installation. Its incorporated drainage channel enables the manufacture and installation of roof sheets up to 180m in length. On-site mobile production units, craned to roof height, remove the need for end laps on long slopes.

SolarWall® - Transpired Solar Collector (TSC) is a solar air heating system that utilises solar radiation to deliver naturally warmed fresh air into buildings.
