Spanish attic insulation costs €15–€50 per m² installed. EPS/XPS rigid boards are the most common choice at €20–€40/m², while spray polyurethane costs €30–€60/m². Spain's CTE (Código Técnico de la Edificación) sets thermal transmittance limits that vary by climate zone — from U=0.50 in warm coastal areas to U=0.23 in cold mountain zones. Subsidies through the PREE (Programa de Rehabilitación Energética) and Next Generation EU funds cover 40–80% of insulation costs depending on the energy improvement achieved. Summer cooling savings are often more significant than winter heating savings in much of Spain.

What affects the cost?
- Insulation type — blown-in is cheapest; spray foam costs 3–5x more but provides air sealing
- R-value target — the DOE recommends R-38 to R-60 for attics depending on climate zone
- Attic accessibility — tight spaces, low clearance, and obstacles increase labor time
- Attic size — typical US attic is 1,000–1,500 sq ft
How to save on attic insulation
- Claim available rebates — utility rebates, federal tax credits, and state programs can cover 30–50% of costs
- Start with air sealing — sealing gaps before adding insulation maximizes energy savings
- Choose blown-in for open attics — it's the most cost-effective option for standard attics
- Top up existing insulation — adding blown-in over old batts is cheaper than full removal and replacement
- DIY blown-in — renting a blower and buying material can cut costs by 50% for accessible attics
