to accommodate movement while offering the cost-effectiveness of a ‘stick’ solution. This expansion joint solution comprises a specialised engineered foam, which expands and contracts in the mullion with the movement of the structure. A transom profile is used at each floor level which allows the spandrel glass/panel to slide within the glazing rebate while maintaining airtightness, ventilation and weather tightness of the system.

A breather membrane is used on the floor transom, which is designed to allow any excess water in the glazing rebate to escape. It is also designed to expand and contract with the racking movements of the glass when subjected to the 15 mm slab deflection.

A key aspect of the development was the performance test methodology to ensure the system would perform when subjected to this level of movement. The supplier worked with the Centre for Window and Cladding Technology (CWCT) to develop the method, which was an enhanced version of the sequence B. This included a structural movement regime comprising three cycles of +/- 15 mm deflection of the structural beams supporting the test specimen.

To complement this systemised solution

the supplier is launching a no-obligation facade workshop comprising a team of facade specialists who will work collabora- tively with developers, architects and engineers during the early stages of a project. The aim is to provide a unique design and consultancy service working across every aspect of the facade to ensure the design intent and every detail is realised, help refine the design, ensure the scheme is ‘value engineered’ and can be built on site safely. The thinking behind this is that early involvement leads to a successful outcome, whether it relates to building movement or facade selection and key design issues in general. The holistic approach is set up to classify facades by function, materials, mullion type, glass type, key components, structural safety, thermal performance and future maintenance.

These consultants understand that architectural trends and features are a key part of a building’s identity and are committed to turning these features and daring concepts into safe reality.

Traditional aesthetic delivered in Lincoln D

urability, safety and aesthetics needed to work together for the Viking House project. With the

refurbishment nestled among conventionally built brick buildings there was a need for a contemporary look that mirrored the local vernacular. MechSlip has a design that allows specifiers and architects to create distinctive facades thanks to the flexibility of different sizes of brick slips and choice of multiple colours and textures, allowing the development to fit seamlessly into its traditional surrounding; Ibstock’s Leicester Red was the brick of choice. Viking House is a managed student accommodation development at the University of Lincoln. Converted from several repurposed properties, the design of the buildings was in contrast to others in the largely traditional of area of Brayford Wharf. One of the main challenges was

the University’s desire to complete the project within only six months in order to accommodate the new intake of students at the start of the 2018/19 term, but without compromising on safety.

Working in partnership with the Globe

Consultants, Ash & Lacy proposed the use of its exclusive MechSlip facade. Developed in conjunction with Ibstock Kevington, MechSlip is a lightweight, mechanically fixed system that offers significant advantages including reduced installation times and associated costs, as well as being completely non-combustible. One of its biggest advantages is the speed

and ease at which MechSlip can be installed, which leads to significant time and cost savings over traditional brickwork. The system works with slip-cutting

technology that allows the vast majority of stock and wire cut bricks to be mechanically

fixed into horizontal rails at flexible heights, making the entire design and installation process simple, from concept to completion. This allows architects and specifiers to use brick to maintain the integrity of their design, whilst the efficiency and versatility of the mechanical fixed system opens up a whole raft of options for integration with modern methods of construction. As well as offering the reassurance provided by a mechanically-fixed design, MechSlip has been rigorously tested to the Centre for Window & Cladding Technology (CWCT) standards, for wind resistance, water tightness and impact resistance. The result is that it eliminates the weather dependency of traditional building methods without compromising on the choice of brick finish. And it also benefits from non-combustible system components making it the ideal choice for a modern high-rise structure like Viking House.
