How Spray Foam Insulation Cuts Energy Bills in Kansas City Homes

Kansas City gets both extremes — 100°F summer heat and subzero winter wind chills. Most KC homeowners see a 30-50% reduction in heating and cooling costs after spray foam insulation is installed. Here's where the savings actually come from.

Why Spray Foam Outperforms Fiberglass in KC's Climate

Fiberglass batts insulate, but they don't air-seal. Air infiltration accounts for 25-40% of heating and cooling energy loss in most homes. Spray foam does both jobs simultaneously — insulate and create an airtight barrier.

Open-Cell vs. Closed-Cell: Which for Your Home?

Open-cell for attics and interior walls. Closed-cell — denser, acts as a vapor barrier — for crawl spaces, rim joists, basement walls, and moisture-exposed areas. Most KC homes benefit from a mix of both.

Where to Install for Maximum Impact

Attics produce the biggest energy impact. Crawl spaces are second. Rim joists (where floor framing meets foundation wall) are one of the most overlooked air leakage points in older homes.
