## Attic insulation in Minnesota The attic is where most Twin Cities homes lose their heat, and it is the cheapest place to get it back. Houses built before 2000 usually have R-19 to R-38 up there. Current Minnesota energy code calls for **R-49**, and R-60 is what we recommend for real winter comfort. ### Air sealing comes first — always Insulation slows heat conduction. It does not stop air movement. If you blow insulation over an unsealed attic floor, warm moist air keeps rising through every gap, carrying heat with it and dumping moisture into the insulation. That is how you get frost on the underside of the roof deck in February and drips in March. So we seal first: - Top plates of interior and exterior walls - Plumbing and wiring penetrations, chases, and soffited ceilings - Recessed can lights (IC-rated covers where needed) - Bath fan and range hood housings — and we make sure they duct **outside**, not into the attic - The attic access hatch or pull-down stair, which is usually a giant uninsulated hole ### Then insulation - **Blown fiberglass or cellulose** to R-49 to R-60 (roughly 16 to 22 inches depending on material) - **Baffles at every rafter bay** so soffit vents stay open and airflow continues - **Dam and insulated cover** around the attic hatch - **Knee wall and slope insulation** in story-and-a-half homes — the hardest and most valuable part of any Minneapolis or St. Paul bungalow ### Planning ranges (Twin Cities, estimates) | Work | Typical range | |---|---| | Attic air sealing | $700 – $2,500 | | Blown-in top-up to R-60, 1,200 sq ft attic | $1,800 – $3,500 | | Full removal and reinstall | $3,500 – $7,500 | | Baffles and vent correction | $500 – $1,800 | | Attic hatch insulation kit | $200 – $500 | | Knee wall / slope insulation | $2,000 – $8,000 | Estimates for planning. Vermiculite (possible asbestos) requires abatement, which we do not self-perform. ### The payback Going from R-19 to R-60 with air sealing typically cuts 15% to 25% off heating cost on a Twin Cities home. On a $1,800 annual heating and cooling bill that is roughly $270 to $450 a year — a **5 to 9 year payback**, before rebates. Xcel Energy and CenterPoint both run insulation rebate programs; check current amounts before scheduling, because they change every year and can knock a meaningful chunk off the job.
