About AstroFoil
AstroFoil is an independent technical resource dedicated to demystifying residential thermal performance. While conventional home improvement advice often relies on simplified cavity R-values, real-world energy efficiency is governed by whole-envelope dynamics: air barrier continuity, radiant heat deflection, and thermal bridging across moving openings.
Our mission is to provide science-grounded, field-tested guidance that helps homeowners, builders, and energy auditors eliminate systemic energy loss. We place particular emphasis on the most overlooked breach points in residential construction—specifically unconditioned transition zones like attached garages, cantilevered bonus rooms, and radiant-heavy attic assemblies.
About the Author: Mike Brown
Mike Brown is a building envelope specialist and home performance consultant with over 15 years of practical experience in residential insulation diagnostics, infrared thermography, and air infiltration remediation.
Throughout his career in residential retrofits, Mike has focused on identifying secondary boundary failures—where uninsulated shared partition walls, leaking door assemblies, and unaddressed radiant heat loads compromise whole-house HVAC efficiency.
His writing and technical reports emphasize empirical testing data and established industry standards (including ANSI/DASMA 105 for dynamic openings and ASTM C1313 for radiant barriers). Mike’s objective is to provide actionable, code-aligned frameworks that eliminate contractor marketing hype and deliver measurable, year-round comfort and energy reductions.
