R-Value (Insulation): R-value is a measurement of an insulation…
Definition
R-value is a measurement of an insulation material's resistance to heat flow — higher R-values mean better insulation. Pacific Northwest energy codes typically require R-30 to R-49 in attics, R-15 to R-21 in walls, and R-30 in crawl space floors, depending on the building's climate zone.
Common Questions
Real-World Example
You'd see this when a homeowner in Camas, WA receives a high winter heating bill — CRM Services performs an attic inspection, finds R-19 insulation that's settled to roughly R-13, and recommends a top-up to current R-49 code.
Why It Matters
R-value upgrades are a recurring component of CRM Services' energy-improvement scope, often bundled into crawl space encapsulation and attic remediation projects.
