Insulation R-Value
Quick Definition
Measurement of insulation's resistance to heat flow - higher R-values provide better energy efficiency and comfort
R-value measures insulation's thermal resistance - its ability to resist heat flow. Higher R-values indicate better insulating properties, leading to improved energy efficiency and comfort in your home.
What You Need to Know
Proper insulation can reduce heating and cooling costs by 15-50%. Different climate zones require different R-values. Common areas needing insulation include attics (R-38 to R-60), walls (R-13 to R-21), and basements (R-19 to R-25).
Why It Matters for Your Home
Inadequate insulation wastes energy and money while making rooms uncomfortable. Poor insulation also creates moisture problems that can lead to mold growth and structural damage.
How to Choose Insulation
Consider your climate zone, existing insulation, and budget. Common types include fiberglass, cellulose, spray foam, and rigid foam. Each has different R-values per inch and installation requirements.
When to Get Professional Help
Professional energy audits identify insulation needs. Complex installations like spray foam or blown-in insulation require professional installation for safety and effectiveness.
