The Homeowner's Guide to Garage Door Insulation in New Jersey

Why Insulation Matters in NJ

NJ experiences temperature extremes — 95°F summers to 15°F winter nights. An uninsulated garage door is a giant hole in your thermal envelope.

Benefits

• Reduce heat loss by up to 71%
• Keep garage 10–20°F warmer in winter
• Noise reduction
• Stronger, more dent-resistant panels
• Protect stored items from temperature damage
• Use garage year-round as workshop/gym

R-Value Guide

• R-0: No insulation (basic single-layer)
• R-6 to R-9: Polystyrene. Good for mild climates.
• R-12 to R-18: Polyurethane. Best for NJ. Superior noise reduction.

For NJ, we recommend R-12+ for attached garages. R-16+ if you heat the space.

Retrofit vs. Replace

Retrofit kit ($100–$200 DIY) works if door is under 10 years and structurally sound. Otherwise, new factory-insulated door ($800–$2,500 installed) is better long-term.
