Fire
resistant.

The fire resistance of KLH® components is proven in a structural analysis.

The structural properties of bare KLH® - CLT panels after a fire of any duration can be calculated using the standard methods described in the NDS, National Design Specification for Wood Construction, and the CLT Handbook, US Ed. Additional fire protection can be achieved through the application of gypsum board or other fire resistant materials.

In the download area, you will find reports of fire tests of KLH® elements per the applicable ASTM Standard. All tests were conducted at recognized US laboratories.

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.
