Old batts leave gaps around every pipe, wire, and stud. Open-cell spray foam expands to fill every opening, insulating and air-sealing your home in one visit.
Open-cell foam insulation in Reno is sprayed directly onto surfaces inside walls, attics, and crawl spaces, where it expands to fill every gap and create a continuous insulating layer. Most residential jobs are completed in one to two days, and the foam reaches its full expansion within minutes of being applied.
The fiberglass batts in most older Reno homes sit between wall studs but leave gaps around wires, pipes, and framing where cold desert air moves freely. Open-cell foam expands to seal those gaps completely, which means it insulates and air-seals in a single step. That combination is what makes it noticeably more effective at reducing drafts and the temperature swings Reno homeowners deal with every winter and summer.
Many homeowners pair open-cell foam with attic air sealing to address the attic floor gaps in the same project. Doing both in one visit lowers labor costs and typically qualifies for higher combined rebate amounts from NV Energy.
If your energy bill climbs sharply from October through February without a change in how you use your home, your insulation is likely failing to hold heat inside. Reno winters are cold and dry, and a home losing heat through the attic or walls forces your furnace to run almost constantly. This is one of the most common and most overlooked signs that an insulation upgrade would pay for itself quickly.
Run your hand along the baseboards or near electrical outlets on an exterior wall on a cold January night. If you feel cool air moving, that is air infiltration, outside air finding its way through gaps in the building envelope. Reno's cold winters make this easy to detect, and it is a clear sign your current insulation is not sealing the home the way it should.
If you notice the smell of wildfire smoke inside your home during an air quality advisory, even with windows and doors closed, your home has significant air leakage. This is a Reno-specific signal that has become more relevant as fire seasons have intensified across Northern Nevada. A properly air-sealed home keeps outdoor air, including smoke, from infiltrating living spaces.
If one bedroom is always freezing in winter or one corner of the house never cools down in summer, the insulation in that area is likely thin, damaged, or missing. This kind of uneven comfort is especially common in Reno homes built in the 1970s and 1980s, where insulation was often installed inconsistently or has settled and degraded over the decades since.
Reno Insulation installs open-cell spray foam in attics, exterior walls, crawl spaces, and rim joists throughout the Truckee Meadows. Because open-cell foam seals as it insulates, it is particularly well-suited to the tight spaces around framing, pipes, and wiring where traditional batts cannot conform to the surface. Every job includes a walkthrough showing exactly what was covered and at what depth before the crew leaves your property.
Open-cell foam is also vapor-permeable, meaning some moisture vapor can pass through it rather than being blocked entirely. In Reno's very dry climate this is generally an advantage, because it reduces the risk of trapping moisture inside wall cavities. Your contractor should assess your home's existing vapor management and confirm open-cell is the right fit before any product is ordered. Where ground moisture is a factor, such as in a crawl space, we may recommend pairing open-cell foam with closed-cell spray foam on the lower surfaces.
For homes where both energy performance and noise reduction are priorities, open-cell foam's soft, porous structure absorbs sound between rooms or from outside. We regularly install it in interior walls for homeowners near the freeway or the Reno-Tahoe Airport who want quieter living spaces in addition to better thermal performance.
Best for homes where heat loss through the ceiling is the primary problem, delivering the highest return on investment in Reno's climate zone.
Best for existing homes with finished walls where adding insulation without full demolition is the goal.
Best for crawl spaces with a dry floor condition where sealing floor joists from below stops cold floors and drafts.
Best for homes with cold first floors, sealing the framing at the foundation line where a large share of lower-level drafts originate.
Reno sits at roughly 4,500 feet in the high desert, and temperatures routinely swing more than 40 degrees between a summer afternoon and the same night. That kind of daily thermal stress means your insulation is working hard in both directions, keeping heat out in July and holding it in during January nights that regularly drop below freezing. Open-cell foam's ability to seal air leaks as well as slow heat transfer makes it especially well-suited to this climate, where drafts and temperature swings are the primary comfort complaints.
A large share of Reno's housing stock was built between the 1970s and the early 2000s, when construction booms brought homes to market quickly but often with minimal insulation standards. Neighborhoods like Midtown, the Old Southwest, and the established subdivisions near Sparks have homes where the original insulation has settled, degraded, or was never adequate to begin with. If your home was built before 2010, there is a good chance your walls and attic are under-insulated by current expectations. The Spray Polyurethane Foam Alliance notes that spray foam applied at the correct thickness is one of the highest R-value-per-inch products available, making it a strong choice for upgrading homes where adding thickness in the wall cavity is limited.
Wildfire smoke has also become a genuine seasonal concern in Northern Nevada, and a well-sealed home reduces how much of that smoke infiltrates living spaces during a high-AQI day. We work throughout the area including Carson City and Truckee, where the combination of cold winters and fire-season smoke makes an airtight building envelope especially valuable.
Reach out by phone or the contact form and we will get back to you within one business day to schedule a free on-site estimate. No pricing is given over the phone, because the right answer depends on what we find when we see your home.
A technician visits your home to measure the spaces being insulated, check what is already there, and assess any access challenges. You receive a clear written quote before any work is agreed to.
On installation day, you and your pets will need to leave the home and stay away for at least 24 hours while the foam cures. Your contractor will give you a specific re-entry time in writing before work begins.
Once the foam is fully cured, we walk through the completed work with you, confirm coverage depth, and provide documentation for any NV Energy rebate or federal tax credit claim you plan to file.

(775) 491-3183Open-cell foam is not the same as installing a roll of batts. Our crew is trained in spray foam application specifically, covering the correct mix ratios, depth measurement, and safety protocols. The Spray Polyurethane Foam Alliance sets the standards we work to on every job. See SPFA installation standards.
Nevada requires insulation contractors to hold a state-issued license. You can verify our license through the Nevada State Contractors Board website before calling us, and we encourage you to do exactly that. A licensed contractor gives you real recourse if anything does not meet the standard we agreed to.
We work throughout the Reno-Sparks metro and surrounding communities, from homes near the University of Nevada campus to newer subdivisions in South Reno and out to the Sierra Nevada foothills. That coverage means we understand the range of housing stock and conditions across this region, not just one neighborhood.
NV Energy rebates and federal tax credits for energy-efficient home improvements can meaningfully reduce your out-of-pocket cost. We provide the project documentation required to file both claims, so you are not left sorting paperwork on your own after the crew leaves.
A properly installed open-cell foam job delivers measurable results you can feel the first day you are back in your home. Reno Insulation brings trained crews, licensed work, and local knowledge to every project, whether the home is a 1970s ranch in Northwest Reno or a newer build near Sparks.
Targeted sealing of attic-floor gaps and penetrations pairs with open-cell foam to eliminate the top two sources of heat loss in most Reno homes.
