Shaftwall Solutions

In towers and multi-storey buildings, the cores carrying lifts, stairs and services have to be enclosed against fire, often in tight spaces with no room to work from both sides. Knauf Shaftwall is a single-access system built entirely from the accessible corridor or room side: the shaft-facing board is installed first into the framing, and the frame is then built outward toward the installer — no access into the shaft required.

Every Knauf Shaftwall is a complete, tested assembly — Coreboard shaftliner, CT studs and J or UW tracks, and room-side boards chosen for fire, acoustic, moisture or impact needs. Together they deliver certified fire resistance of up to 120 minutes and sound insulation up to 56 dB in a slim, lightweight build-up.

Knauf Coreboard is the 25.4mm fire- and moisture-resistant shaftliner that forms the shaft-facing layer of every Knauf Shaftwall, friction-fitting into the framing for fast, simple construction. Available as GB-WRTX (ASTM) and FM (EN-BS).

Lightweight drywall shaftwall installs floor-by-floor with no scaffolding, no wet trades and no curing time, keeping the build programme moving. It's up to 90% lighter than blockwork, recovers floor area through a thinner build-up, and flexes with seismic and differential movement rather than cracking, a meaningful advantage over rigid masonry cores.
