Summary
In this episode of Beers with Contractors, host Will and Terry recap their fifth Construction Camp for Kids event and welcome longtime friend Alfonso Nieves of Fox Blocks (Airelite Plastics), an insulated concrete form (ICF) expert who trains contractors nationwide and with the National Home Builders Association. Alfonso explains how he entered the ICF industry, the technology’s origins in Canada in the 1960s, and why above-grade ICF excels for energy efficiency. They discuss ICF benefits including continuous insulation, fire rating, sound attenuation, storm resilience, fewer foundation issues, and faster construction (about 15% faster than finished CMU), plus typical cost premiums (about 7–10%) with a 5–10 year payback. Alfonso addresses myths (termites, “double the cost,” lack of installers, “houses don’t breathe”), covers rebar options and additives, outlines training availability via foxblocks.com, and shares contact info. 00:00 Introduction 01:23 Meet Alfonso Nieves 03:11 How Alfonso Nieves Found ICF 05:18 ICF Across Climates 07:16 ICF History Evolution 09:06 Beyond Homes Use Cases 10:37 Cost ROI Payback 12:36 Storm Safety Foundation 14:25 Speed Scheduling Cashflow 16:42 Myths Termites Cost 18:33 Affordable Housing Example 19:29 Tight Envelope HVAC Downsizing 20:42 Rebar Alternatives Logistics 25:33 FRP Rebar Availability 26:01 Thin Brick With ICF 27:54 Finding Fox Blocks Training 29:16 Construction Camp Stories 31:44 Lintels And Big Openings 34:04 Floor Systems On ICF 35:27 Fastening Strips Deep Dive 39:52 DIY Vs Pro Install Reality 42:36 Materials And Recycling Ties 45:07 How To Reach Alfonso 46:21 Final Wrap And Disclaimers Contact Alfonso Nieves at: Website: https://www.foxblocks.com/ Email: [email protected] LinkedIn: https://www.linkedin.com/in/alfonso-n…
