CLST

CLST - Composite Laminated Structural Timber

CLST is an advanced engineered timber product that combines the grain alignment advantages of glulam with the multi-directional strength of CLT, resulting in a panel system optimised for heavy structural loads and long spans.

Key Advantages

• High Bending Stiffness: Optimised layup sequences provide superior stiffness-to-weight ratios compared to standard CLT.
• Long Spans: Suitable for spans exceeding 12 m without intermediate supports, enabling open-plan floor layouts.
• Dimensional Stability: The composite layup minimises creep and shrinkage, ensuring reliable long-term performance.
• Acoustic Performance: Increased mass provides better airborne and impact sound insulation than lighter timber systems.
• Prefabrication Ready: All panels can be CNC-machined for connections, openings, and service penetrations before delivery.

Panel Options

CLST panels are produced in widths up to 2.95 m and lengths up to 18 m, with thicknesses from 120 mm to 400 mm. Hybrid configurations incorporating hardwood face veneers are available.

Typical Applications

• Long-span floor decks in commercial buildings
• Industrial and warehouse roof systems
• High-load bearing wall systems for multi-storey structures
• Bridge deck elements
• Hybrid steel-timber structural systems

Standards & Testing

CLST products are tested to EN 16351 and EN 14080 standards. Full structural performance data is supplied with every project delivery.
