From World of Concrete| Build Show Podcast Ep 205

Insulation technology is shrinking: thinner panels now hit the same or higher R-value, and one vacuum-sealed panel on display delivered roughly R60-66 per inch.

Fasteners are a hidden budget line; a rooftop insulation job's fasteners alone can run $6,000-$8,000, so thinner assemblies save on far more than just material.

Spray foam gets unfairly maligned; used by qualified installers in the right spots like band joists, it delivers both insulation and air-tightness, and complaints usually trace back to poor research and cheap labor.

World of Concrete is a commercial-oriented show and not ideal for the typical custom builder, but the payoff of attending is spotting what's genuinely new rather than the same tape from 1988.

Matt and Steve share a 'discipline of innovation' with tool and material makers: different boats rowing the same direction to make the whole industry better.

Trade shows put you face-to-face with surprisingly generous high-level technical people, including company presidents and patent-holders willing to answer nerdy questions.

Community is the throughline; the Build Show is expanding its Build Pros network across regions (California, mountain, Florida coastal) to represent every type of build.
