// LESSONS FROM IRC Building Sciences Group, A Rimkus Company
Justify premium materials by quantifying the labor they eliminate, not just the product cost — if you can show the expensive membrane saves two layers of install, contractors will buy in.
Do a thermal (IR) scan before speccing any roof replacement — pinpointing wet sections lets you recap only the damaged 10-20% and save the building owner substantial cost and material.
In a supply-constrained market, check manufacturer lead times and contractor availability before writing the spec — then design around what's actually obtainable.
Labor shortage is a product-design signal: Soprema created laminated Smart Board panels specifically because fewer skilled hands meant quality-control problems on-site.
Vertical integration of essential components gives a manufacturer supply-chain control that competitors lack — acquiring upstream suppliers is a deliberate strategy, not just M&A.
A building sciences firm going 'on site before specking it out' — doing core tests, thermal scans, and leak investigations first — earns the trust of building owners who don't know where to start.
