Cross Laminated Timber

Overview

XLam Cross Laminated Timber (CLT) panels are structural timber panels made with layers of finger jointed radiata pine lamellas arranged at right angles to one another, laminated together with a moisture cured polyurethane glue applied to the face under pressure. The 90-degree cross lamination of alternate layers provides dimensional stability, strength, and rigidity.

XLam CLT panels can be manufactured to a maximum plan dimension of 15.7m and a width of 3.4m providing a two-way span with structural performance. Panel thickness depends on the intended load and span. The most common configurations have three, five or seven layers, with panel thicknesses between 90mm and 310mm.

Application

XLam CLT panels are manufactured off-site and are suitable for use in mass timber and hybrid construction in the commercial, governmental and residential markets.

XLam has over 10 years of experience and a proven track record providing structural timber elements to the New Zealand market. XLam provide comprehensive guides, design and construction services, local sales, technical support and advice, and installation support.

XLam’s highly qualified engineering, architecture, project management, construction and technical teams will assist and support your project design team.

The most economical building outcome is reached when CLT is integrated at the conceptual stage. An early design consultation with XLam will optimise the performance of CLT, dealing with considerations such as economical panel sizes, orientation, tolerance for assembly, appearance, durability, buildability, and construction sequencing.

Given sufficient preliminary design information, XLam will provide an early estimate of likely CLT supply costs to facilitate project planning, including floor spans, loadings, anticipated bracing, and a general understanding of design requirements.

Benefits

Safety: The prefabricated nature of mass timber has proven positive impacts on site safety for customers, reducing the number of processes to be performed on site, reducing headcount on site, and providing
a safe approach to achieve rapid construction while reducing risk.
Sustainability: Low embodied energy, carbon sequestration, renewable, plantation timber. CLT is a renewable resource that sequesters carbon dioxide from the atmosphere and locks it in as carbon within a building providing a form of biophilic design.
Modular Construction: XLam CLT panels are manufactured off site and are suitable for mass timber and hybrid construction.
Durable & Strong: Due to high strength-to-weight ratios mass-timber performs well during earthquakes.
Local Expertise & Advice: XLam’s experienced in- house technical team works with clients and project partners to provide advice and support for design and engineering.
Lightweight: At 20% of the density of concrete, wood offers more density per area than any other construction material, allowing for taller vertical extensions and greater quantities of material on softer ground.
Efficiency: Incorporating prefabricated CLT typically reduces construction time and improves efficiency. Reducing time on site offers benefits for builders, developers and asset owners including; reducing capital and funding costs, achieving greater revenue and built-form turnover with the same labour resources, and improving project ROI.
