Spray Foam that seals the cold out of your Ames home.
Open and closed-cell spray foam for Ames rim joists, crawlspaces, and attics. Air-seal and insulate in one pass, control basement moisture, meet Iowa energy code.
Ames spray foam for the spots batts cannot seal.
Spray foam is the tool for the places where batts and blown fill fall short. It expands into every gap, cures into a rigid air barrier, and delivers its R-value and air seal in a single application. For an Ames home fighting a leaky rim joist, a damp crawlspace under an older near-campus house, or a cathedral ceiling that batts cannot seal, foam does in one pass what other materials need two steps to attempt.
Patriot Gutters & Insulation sprays both chemistries. Closed-cell is dense, gives the most R-value per inch, and acts as its own moisture barrier, which is why we lean on it for rim joists and crawlspaces in the central Iowa climate. Open-cell is lighter and expands further, a strong choice for attic roof decks and interior walls where you want the air seal without a vapor barrier. We are a Woodward gutter and insulation contractor working across Story County and the Des Moines metro, and Ames gives us both the old drafty basements and the new builds, so we spray both regularly. The chemistry follows the assembly, not the sales pitch.
The advantage that matters through an Iowa winter is the air seal. Batts and loose fill slow heat but do nothing to stop the air movement that drives most of a home’s energy loss and its condensation problems. Foam stops the air and insulates in the same bead, which is why a foamed rim joist or an encapsulated Ames crawlspace changes how the whole floor above feels and holds temperature. We spray to the thickness your assembly and the Iowa energy code call for, and we document the product and depth.
Closed-cell, open-cell, and where foam stops.
Closed-cell for the wet, cold spots
Closed-cell foam is the dense one. It delivers roughly R-6.5 to R-7 per inch, the highest of any insulation we install, and it cures rigid enough to add real racking strength to a wall. Most important in Ames, it is its own vapor and moisture barrier, so it belongs in the spots where cold and damp meet: the rim joist band where the framing sits on the foundation, and the crawlspace or basement wall of an older near-campus home that has run cold and musty for decades. Seal those with closed-cell and the cold-floor, damp-air complaint upstairs usually goes with them.
The high R-per-inch also matters where there is no room for depth. A shallow rim joist or a tight cathedral cavity cannot hold fourteen inches of blown fill, but a few inches of closed-cell reaches code value and air-seals in the same pass. That thin, high-performance profile is exactly why foam earns its place on an Ames retrofit.
Open-cell, and the jobs foam should not do
Open-cell foam is lighter and expands further, giving roughly R-3.5 to R-3.8 per inch. It is a strong choice for an attic roof deck or an interior wall where you want the air seal and sound-deadening without a vapor barrier, and it costs less than closed-cell per board foot. On the right Ames assembly it is the smarter pick, and we spec it where the vapor profile calls for a material that can dry.
Foam is not the answer to everything, and we will tell you where it stops. An open attic floor does not need foam: blown cellulose reaches R-49 there for far less money. We use foam where the air seal and the thin, high-R profile earn their cost, the rim joist, the crawlspace, a cathedral ceiling, a bonus room over a garage, and let blown-in handle the open attic. Matching the material to the spot is what keeps an Ames quote honest.
Same workflow on every Ames job.
Assess the assembly
We look at the rim joist, crawlspace, or ceiling, check for moisture and existing insulation, and decide open or closed-cell based on the vapor profile and depth available.
Prep & protect
We mask adjacent surfaces, clear the spray zone, and ventilate the area. Any bulk moisture or rot in an old Ames crawlspace is flagged and addressed before foam goes on.
Controlled spray
Foam is sprayed in even lifts to the target thickness, filling every gap and curing into a continuous air and moisture barrier across the assembly.
Trim & inspect
Overspray is trimmed where it needs to sit flush, and we inspect the full run for coverage, adhesion, and any voids that need a touch-up pass.
Cure & ventilate
We give the foam its cure and re-entry window, keep the space ventilated, and confirm the assembly is sealed and dry before the crew clears out.
Document & sign-off
You get the product data, the sprayed thickness, and photos for your records, so an Ames energy-code or tax-credit filing has everything it needs.
The Ames spots foam fixes best.
Rim joist band
The rim joist where the framing meets the foundation is a classic Ames energy leak, a thin band of wood exposed to outdoor air all winter. A few inches of closed-cell foam air-seals and insulates it in one pass, and it is often the highest-return small job we do on an older home.
Crawlspace and basement
A cold, damp crawlspace under a near-campus Ames home pushes musty air and cold floors upstairs. Closed-cell on the walls and rim seals out the moisture and the air leak at once, and the whole first floor stops feeling like the basement is winning.
Cathedral and vaulted ceilings
A cathedral or vaulted ceiling has no attic to blow, and batts leave gaps that leak heat and invite condensation. Foam fills the rafter cavity, air-seals it, and reaches code R-value in the depth available on an Ames roof.
Where we do not use it
We will steer you away from foam on an open attic floor, where blown cellulose reaches R-49 for far less. Foam is for the air-seal and thin-profile jobs. Sending you the right material for the spot is how we keep an Ames project honest on price.
