The largest mass timber building by volume in the US is under construction in Cleveland, Ohio. Known as INTRO, it is a US$130 million mixed-use building with amenities, like a rooftop terrace, bike hangar, library lounge, and co-working spaces.
Notably, it will feature visible wood in parts of the interior. The cross-laminated timber (CLT) and glued laminated timber (glulam) is supplied by Binderholz Group and sourced from certified sustainably managed Austrian forests.
INTRO is not the first large-sized US project for Binderholz. It supplied over 4,000 m³ of both CLT (tradename Binderholz CLT BBS) and glulam (tradename Binderholz glulam) for 'Adohi Hall', an award-winning 700-room student residence at the University of Arkansas completed in 2018.
Binderholz certified its products in North America in 2018 using Henkel Loctite HB X. The Henkel Loctite HB X is a formulation developed to enable CLT and glulam manufacturers meet the demanding requirements for heat and fire performance in North America.
Standards in the region require extensive fire testing and rating procedures for CLT and glulam, and charring characteristics that are like solid timber.
In the meantime, Henkel Engineered Wood has certified HB X on three continents, enabling leading manufacturers like Binderholz to address a greater range of markets and greater range of projects and building sizes, heights, and purposes.
