General information

Solid architectural bronze systems

Our solid systems are manufactured entirely from architectural bronze, giving the same appearance inside and out, with a thermal break as standard in all windows and doors. Sturdy and durable, the solid profiles are extruded rather than cold-rolled, providing defined design detail for a refined appearance. The high tensile strength of the solid systems enables narrow frames to be achieved even on large windows, for a superior aesthetic finish.

Composite architectural bronze systems

Our composite systems are designed and manufactured with authentic architectural bronze exteriors and an aluminium, steel or timber core. The copper alloy contains natural properties which create a corrosion and rust-resistant barrier, and the aluminium core shares anti-corrosive properties. Given the excellent strength-to-weight ratio of a composite interior, it provides an ideal alternative to a solid system, due its relative ease of handling and installation. The timber core provides a thermally efficient option as well as representing a sustainable solution, combining two natural materials each excelling in their respective strengths.

Bi-metallic system testing

Every component of our composite systems has been rigorously tested and analysed to verify that the use of bi-metallic componentry is non-corrosive. As an additional precaution, isolation layers are included within all our systems as standard, to provide further assurance that the integrity of materials used cannot be compromised.

The patination process

Architectural bronze is a natural copper alloy made up of two key components: copper and zinc. As a result, oxidisation – the variation and darkening of the surface on exposure to the environment – will occur naturally over time. Given the unpredictable nature of the elements involved in the patination process, it is impossible to pre-determine the exact timescale and level of chromatic surface variation that will take place. There are no fixed upper or lower limits to the oxidisation process, which only adds to the truly unique quality of architectural bronze.

Patination sample guides are available which illustrate the range of colours that can be achieved.


Sections and profiles are machined to provide pathways for water drainage, and control and reduce the impact of humidity. Cover caps can be provided to protect any external drainage slots within profiles on request.


All systems can be provided with or without glass, according to each customer specification. We work with a wide range of specialist glazing suppliers, depending on specific project requirements.


The type of maintenance required for architectural bronze systems depends on the stabilisation process used. For natural wax, we recommend an annual maintenance programme to ensure that architectural bronze is kept in optimal condition; this involves the re-application of a layer of wax to the surface of the material.

The maintenance schedule required for an HPN stabilised surface is minimal. The surface of this finish can simply be washed down with water or a mild detergent as part of the glazing cleaning programme, or as required.

All Faber Verus system components come with transit protection. If protection is required on site for longer than a period of fourteen days, contact us to discuss the options available.


Both solid and composite systems must be stored in a cool, dry area, and architectural bronze structures must be protected from contact with other materials before installation. Should long-term storage be required, please get in touch to discuss any potential for product impact.
