For small domestic extensions, timber remains a viable option. However, for multi-story developments and rooftop extensions, the benefits of metal stud partitioning are undeniable. It offers a faster, safer, and more precise foundation for the high-quality finishes your clients expect.
A technical guide for developers, architects, and main contractors — covering what SFS infill systems are, how they connect to primary structures, the key design and deflection considerations, and what distinguishes a well-specified infill package from one that creates problems on site.
SFS forms the structure. Drylining finishes it. On commercial projects, the interface between the two is where coordination succeeds or fails. This guide explains how the systems connect technically, where the scope boundaries lie, and why a combined package appointment consistently outperforms a divided one.
A practical reference for architects, main contractors, and QS professionals specifying fire-rated drylining systems in commercial construction — covering Approved Document B, performance ratings, system types, and the specification decisions that determine whether a build passes inspection.
An SFS package typically includes design, supply, installation, and project coordination. For developers, it offers a more efficient way to manage quality, cost control, and programme delivery.
Steel Framed Systems (SFS) are rapidly becoming the preferred construction method across London, offering a fast, efficient, and reliable solution for modern developments. Used in both residential and commercial projects, SFS provides a lightweight, high-performance alternative to traditional building techniques.
As the construction industry pivots toward faster, more sustainable building methods, Steel Framing Systems (SFS) have emerged as the premier solution for modern building envelopes. Unlike traditional masonry, SFS utilizes high-strength, cold-rolled galvanized steel to create a lightweight yet incredibly durable structural framework.
The Denham Crematorium project in Uxbridge, completed in early 2026, is a case study in what competent SFS installation actually looks like under pressure. This project to explore the practical demands of a full-package SFS delivery, the operational challenges the system must accommodate, and the qualities that distinguish a capable SFS subcontractor from one who simply carries the accreditation.
When procuring large-scale drylining packages, Quantity Surveyors and Commercial Managers face a decision that carries far more risk than many in the supply chain appreciate. A poorly chosen drylining subcontractor can cascade delays across follow-on trades — MEP first-fix, flooring, ceilings, and the final snagging programme
