Insulation Details
Insulation Basics
R-value measures insulation's resistance to heat flow. Higher R-values mean better insulation. Most homes built before 1980 are significantly under-insulated by modern standards.
- • Attic: R-38 to R-60 recommended
- • Walls: R-13 to R-21 recommended
- • Floors: R-25 to R-30 recommended

FAQ
Where should I insulate first?
Start with your attic - it typically offers the best ROI because heat rises and escapes through the roof. It's also usually the easiest and cheapest to access. After the attic, prioritize air sealing, then walls and floors.
What about air sealing?
Air sealing is crucial and should be done before adding insulation. Air leaks can account for 25-40% of heating/cooling losses. Sealing gaps around pipes, wires, recessed lights, and attic hatches dramatically improves insulation effectiveness.
DIY or professional installation?
Attic insulation (blown-in or batts) is a common DIY project and can save 30-50% on labor. Wall insulation usually requires professional installation. Always wear proper safety gear and check for asbestos in older homes before disturbing existing insulation.
