Technical,
high quality.

KLH® cross laminated timber panels offer excellent structural properties due to the cross-wise structure of laminations, and also provide the capability of transferring load in both directions, making double cantilevers and 2-way plate designs possible. Panels used as wall elements can be used in traditional bearing wall applications, as shear walls for lateral load resistance, as fire-resistant building core walls, and as headers and deep cantilevered beams carrying roof and wall loads. In other words, KLH® - CLT panels can provide innovative solutions for a wide variety of building types and structural members.

The lumber used in KLH® - CLT is classified as Austrian spruce, a species recognized in Table 4F of the NDS Supplement. Also, KLH® - CLT is manufactured in strict compliance with PRG 320, Standard for Performance-Rated Cross-Laminated Timber (ANSI/APA PRG 320) with a custom CLT layup CV3M1, as permitted per Section 7.2.1 of the standard.

Also, KLH® - CLT is manufactured with an approved adhesive in compliance with the requirements for elevated temperature performance in accordance with Annex B of PRG 320-2018.

high load-
bearing capacity

KLH® - CLT panels offer high load carrying capacity, while at the same time being very lightweight compared to other construction materials. Therefore, relatively thin panels of longer spans are possible, and the two-way structural capacity also provides an efficient substructure for distributing the effects of concentrated loads.

KLH® - CLT panels can be used for lateral load resistance in areas of high seismicity with careful detailing of connections. In fact, considerable reductions in seismic force can be realized because of the lower weight of CLT. The engineering staff of KLH-US stands ready to provide assistance and support to design teams with regard to any unusual or high-demand project requirements.

The structural properties of KLH® - CLT panels can be calculated using standard methods described in PRG 320, Standard for Performance-Rated Cross-Laminated Timber, NDS, National Design Specification for Wood Construction, and the CLT Handbook, US Ed. These properties are also tabulated for all KLH® - CLT panels in the document, Structural Pre-Analysis Tables, available for download. CLT is a unique structural material because of the cross-wise lamination build-up, so shear deformations can be significant and must be incorporated into deflection calculations. In addition, because of the relatively thin panels possible with longer spans, vibration caused by human occupancy must be quantified. KLH® US staff is always available and happy to assist the design team with questions about vibration performance or any other issues unique to CLT.

We provide thoughtful design solutions that are structurally and material efficient as well as ecologically appropriate, focusing on a healthy world for future generations.

Sergey David | Technician

I love the beautiful and elegant design solutions that are possible with mass timber. CLT is structurally efficient and naturally fire resistant, and is often the best choice for demanding construction schedules and challenging project sites.

Howard Thurston | Head of Engineering

Our team continually strives to provide the very best quality product, supported by a professional and personalized process. We feel integrity is critical to a successful project and a beautiful end result.

Michael Hahn | Design Director

You have the vision. We have the knowledge and material to make it a sustainable mass timber reality.
