In their words

Why Prolam builds on SPEC

“We partnered with SPEC Toolbox so we can join them on the mission of bringing mass timber into the mainstream. We saw it as a great opportunity to help New Zealand designers and engineers use sustainable products and buildings. SPEC Toolbox is making it easy for engineers to specify mass timber products to build a better, more sustainable New Zealand.”

— John Woodman, Founder and Managing Director, Prolam
