In Poland, attic insulation (ocieplenie poddasza) costs PLN 40–120 per m² installed, depending on material and thickness. Mineral wool (wełna mineralna) at 20–30 cm thickness is the standard choice, costing PLN 40–80/m² installed. PUR spray foam costs PLN 80–200/m². Polish building regulations require a U-value of 0.15 W/(m²·K) for roofs in new construction, equivalent to roughly 25–30 cm of mineral wool. The "Czyste Powietrze" program offers subsidies of PLN 10,000–37,000 for thermal modernization including attic insulation, depending on income level. Most Polish homes built before 2000 have insufficient attic insulation and benefit significantly from upgrades.

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
