When it comes to exterior materials, the options are many. With a broad range of cladding products and facade systems, both new and traditional, to choose from specifiers are spoilt for choice.
Always a critical element in the aesthetic aspirations of architects, facades are now so much more than that. Beyond design and the role, they continue to play in presenting themselves to the world, the exteriors of commercial buildings are also assessed through the lenses of things like acoustic performance, thermal efficiency, sustainability, and fire safety.

Robertsons Facades
Brick Inlay is an innovative facade solution, whose manufacturing process involves embedding thin brick, porcelain, or stone into precast concrete panels. The appeal of the product is that it combines the look and feel of a traditional brick facade or wall with the efficiencies and benefits of precast concrete.
With panels delivered on site, ready for installation, construction time and cost are significantly reduced, without any negative affect on design ambition or the result. In other words, the product enables specifier to customise any pattern and texture they seek, and see the job through to completion, efficiently and cost-effectively.
In terms of site management, the comparison between Brick Inlay and traditional brickwork are stark. With no brick, sand, lime, cement and lintel storage to handle, no onsite waste to deal with, and no need for site amenities for brick laying crews, the whole job becomes significantly simpler. In the case of Brick Inlay, scaffolding is not even required.
Rubner Theca
Mass timber (also known as engineered timber) is a new category of structural timber that has pushed the boundaries concerning the capabilities of timber well beyond low-rise residential construction. With its improved strength and structural properties, it is a viable alternative to concrete and steel in some commercial applications.
The production of mass timber involves gluing, nailing, or doweling layers of wood together to create materials that are far stronger than traditional timbers and boast an impressive weight-to-strength ratio. Available in various thicknesses, sizes, and grades, they are suitable for use as structural elements in tall structures and those with long spans.
The benefits of Mass Timber are many. They can contribute to construction flexibility, reduce labour and equipment costs, provide foundational savings, and contribute to faster completion of jobs. On top of that, the low embodied energy associated with products of this type, combined with the fact that timber is not just a replenishable resource but one that sequesters carbon from the atmosphere, make them a sustainable option.
