Insulation for Monticello Homes, Shops and Farm Buildings

Monticello has a mix of older homes around the courthouse square, newer houses on the edges of town, and farm shops and pole barns out in the county. Older homes often have thin or settled attic insulation, while outbuildings are frequently left uninsulated.

Blown-in attic insulation is a quick, affordable way to make an older Monticello home more comfortable year-round. For new construction, additions, shops and pole barns across Piatt County, closed-cell spray foam insulates, air-seals and blocks moisture in a single application.

Closed-cell spray foam insulation on the walls and roof framing of a new building in Central Illinois

Closed-Cell Spray Foam

Closed-cell spray foam is a premium, high-density, polyurethane insulation that delivers unmatched thermal performance by completely sealing a building’s envelope. It expands to fill every gap and hardens into a rigid, seamless shell, acting as both a powerful insulator and a heavy-duty moisture barrier.

Key Benefits:

  • Highest R-Value: Maximum energy efficiency and climate control per inch.

  • Total Vapor Barrier: Locks out drafts, moisture, and mold.

  • Structural Strength: Hardens to reinforce walls and roof decks.

  • Permanent Solution: Will not sag, settle, or degrade over time.

Blown-In Insulation

Blown-in insulation is a highly efficient, loose-fill material used to quickly blanket attics and enclosed walls. Installed using a specialized blower, it settles perfectly around pipes, wiring, and irregular framing to create a seamless thermal barrier and eliminate cold spots.

Cellulose vs. Fiberglass:

  • Cellulose: Made from densely packed, fire-retardant recycled paper. It provides a higher R-value per inch and superior sound dampening, making it an excellent eco-friendly choice for maximizing thermal resistance. However, it is heavier and can absorb moisture if a roof leak occurs.

  • Fiberglass: Made from lightweight spun glass fibers. It is inherently moisture-resistant (won't support mold) and resists settling over time. It is ideal for older homes where ceiling weight is a concern, though it requires a thicker layer to match the thermal performance of cellulose.
