Mass Timber Construction on the Rise

Customers turn to Hilti for mass timber solutions

Mass timber construction has been on the rise in recent years thanks to its many features, such as smaller carbon footprints, faster construction times, and the ability to do more on-site fabrication.

As a result, Hilti is focusing on how to better support this construction type and has become a leader in innovative and efficient pre-fabricated solutions while offering greater options for the firestopping needs of complex mass timber projects.

In addition to this, with the publication of Technical Report 070 (TR070) and ETA 19/0194 it is now possible to use HILTI HIT-RE 500 V3 in glued-in rod (GIR) connections for mass timber construction.

Firestop support and solutions

Firestop is often an important design consideration in mass timber projects. Passive fire protection is vital for creating a safer and model code-compliant building. Hilti offers a variety of solutions that can be installed in pre-fabricated timber elements. This means you can install firestop in pre-fabricated timber elements before they leave the factory — helping to reduce construction time on site by as much as half.

Firestop in mass timber testing

Please enter alternative text here (optional)

Model building codes require firestop systems to be tested and approved and all firestop systems must be based on testing. Until recently, there were no listed firestop systems for mass timber in North America, and engineering judgments were frequently needed to address mass wood timber firestop applications.

Hilti is the first organization in the world to develop listed and certified firestop systems in cross-laminated timber (CLT) in accordance with ASTM and UL standards. Our extensive testing data in mass timber, along with successful testing of firestop solutions in CLT at Intertek, has paved the way for Intertek listed systems.

Hilti now has five firestop Listings for Mass Timber in Accordance with ASTM E814/UL 1479. These through penetration systems include testing for metallic pipes, nonmetallic pipes, cables and HVAC lines.
