Movement and Tolerances

Architectural drawing of a curtain wall elevation with several cross-sectional and detailed views showing assembly components and measurements.

A detailed multi-part case study exploring movement and tolerances in diverse facade types. It covers unitised curtain walling systems with and without spigots, stick curtain walling, and lightweight steel frame backing wall systems commonly used in rainscreens, brick masonry, and render build-ups. The case study is regularly updated based on member requests and feedback to ensure relevance and practical value.

A professional development certificate layout with a placeholder for a name and course details. It indicates completion of a short course in façade design contributing to a Level 5 Diploma. Issued by the Institute for Architectural Science and Technology in the UK, featuring course title "Structural Considerations in Façade Design and Engineering." Includes UK flag and IAST logo.

Movement and Tolerances in Unitised Systems with Spigots

This case study explores the accommodation of movement and tolerances in unitised curtain walling facades with spigots. The course pays particular attention to the movement of curtain walling units and their fixing to the slab. The movement and tolerances of the façade were achieved with all standard systems (profiles, fixings, subframes, etc). The unitised curtain walling creates a robust envelope of the building. The case study includes video tutorials, drawings and 3D models to achieve the best learning outcomes.

Movement and Tolerances in Unitised Systems without Spigots

This case study explores the accommodation of movement and tolerances in unitised curtain walling facades without spigots. The course pays particular attention to the movement of curtain walling units and their fixing to the front of the slab. The movement and tolerances of the façade were achieved with all standard systems (profiles, fixings, subframes, etc). The unitised curtain walling creates a robust envelope of the building. The case study includes video tutorials, drawings and 3D models to achieve the best learning outcomes.

Movement and Tolerances in Stick Systems

This case study explores the accommodation of movement and tolerances in stick curtain walling facades. The course pays particular attention to the movement of curtain walling units and their fixing to the slab. The movement and tolerances of the façade were achieved with all standard systems (profiles, fixings, subframes, etc). The curtain walling creates a robust envelope of the building. The case study includes video tutorials, drawings and 3D models to achieve the best learning outcomes.

Movement and Tolerances in Lightweight Steel Framing

This case study explores the accommodation of movement and tolerances in the lightweight steel framing. The course pays particular attention to the movement of vertical studs and horizontal tracks. The movement and tolerances of the façade were achieved with all standard systems (profiles, fixings, subframes, etc). The steel arrangement forms a robust framing for the rest of the envelope. The case study includes video tutorials, drawings and 3D models to achieve the best learning outcomes.
