Standard batts leave gaps that outdoor heat pours through all summer long. Open-cell foam expands to fill every corner, sealing your home against the North Texas heat.

Open-cell foam insulation in Sherman, TX is a soft, spray-applied material that expands up to 100 times its original volume on contact, filling gaps around wires, pipes, and framing that traditional batt insulation simply cannot reach - most residential attic or wall jobs are completed in a single day.
Most Sherman homes that struggle with high cooling bills are not just losing heat through walls and ceilings - they are losing conditioned air through dozens of small gaps that standard insulation leaves unsealed. Open-cell foam works differently because it seals those gaps at the same time it slows heat transfer, creating a continuous barrier without seams or compression points. Homes in Sherman built from the 1950s through the 1980s often have original insulation that has settled and compressed over the decades, leaving the thermal envelope well below what is needed for today's energy costs. Open-cell foam is one of the most effective ways to correct that without a full renovation.
For areas where moisture resistance is also a priority, open-cell foam pairs well with commercial insulation strategies and works alongside spray foam insulation products to cover every part of your home's envelope.
If your electric bill climbs dramatically from May through September despite not changing your habits, your home is likely losing the battle against North Texas heat through gaps in the attic or walls. Sherman summers are long and punishing, and a house with poor air sealing forces your AC to run almost continuously just to hold temperature. That is not a thermostat problem - it is an insulation problem.
Walk through your home on a July afternoon and pay attention to whether some rooms feel significantly warmer than others. Rooms directly under the roof, rooms on the south or west side, or rooms above a garage are common trouble spots in Sherman homes. Uneven temperatures almost always point to gaps in insulation or air sealing that open-cell foam can address.
Hold your hand near an electrical outlet on an exterior wall on a hot summer day or a cold winter evening. If you feel air moving, that is outdoor air finding its way through the wall cavity. This is especially common in Sherman's older homes, where original insulation has settled or was never installed correctly in the first place.
If you can safely peek into your attic and the insulation looks compressed, discolored, or does not cover the floor evenly, it is not doing its job. Many Sherman homes from the mid-20th century have insulation that was adequate by the standards of its time but falls well short of what is needed to handle today's energy costs and climate demands. A contractor can measure the actual depth and condition during a free assessment.
We apply open-cell foam to attic rafters, wall cavities, and interior-facing surfaces throughout homes in Sherman and Grayson County. For attic applications, the foam is sprayed between and across the rafters, creating a continuous air barrier that stops heat gain at the roof rather than allowing it to build up in the attic space. This is particularly effective in Sherman's climate, where attics can reach extreme temperatures on summer afternoons. We also install open-cell foam in interior wall cavities during renovations, where its ability to expand around framing irregularities makes it more thorough than batts or rigid board.
Open-cell foam is the softer, more affordable option in the spray foam family, and it expands more aggressively than commercial insulation products, making it ideal for filling large cavities like attic rafters or tall interior walls. When a project calls for maximum moisture resistance alongside thermal performance - think crawl spaces or rim joists - we pair open-cell work with spray foam insulation so every part of the envelope gets the right material for the job.
Best for homeowners wanting maximum air sealing in the attic without the higher cost of closed-cell foam - converts the attic into a conditioned space.
Suits renovation projects where walls are open and a thorough, gap-free seal is the priority alongside standard thermal performance.
Ideal for homeowners who want to reduce noise transfer between interior rooms, since open-cell foam absorbs sound better than dense rigid materials.
A cost-effective choice for commercial buildings where large open cavities need thorough air sealing without the per-square-foot premium of closed-cell products.
Sherman sits in Grayson County where summer temperatures regularly climb above 100 degrees and the cooling season dominates the annual energy budget for most households. That sustained heat puts enormous pressure on your home's envelope - every gap in your attic or walls is a path for outdoor heat to pour in and force your air conditioner to work overtime. Open-cell foam's ability to seal those gaps tightly makes it especially valuable here. Sherman also has a significant number of homes built from the 1950s through the 1980s, many of which still have original fiberglass batts that have settled and compressed over the decades. The U.S. Department of Energy recommends air sealing alongside insulation upgrades as one of the most cost-effective ways to reduce home energy use - and open-cell foam does both in a single application.
Homeowners in Denison, TX and Pottsboro, TX face the same clay-soil movement and summer heat conditions as Sherman. Open-cell foam is flexible enough to move slightly with shifting framing, which means the air seal stays intact even as the ground beneath the home expands and contracts with the seasons - a problem unique to this part of North Texas that rigid insulation materials struggle to handle.
When you call or submit a request, we ask a few quick questions about your home's age and which areas you want insulated. We schedule an on-site visit within one business day - no obligation, no cost.
We walk through your attic, walls, or crawl space and look at the current insulation, any moisture or pest issues, and how accessible the space is. We show you exactly what we find before discussing any work.
After the walk-through you receive a written quote breaking down the area covered, depth of foam applied, and total cost. If the City of Sherman requires a permit for your project, we note that upfront and handle the process for you.
Our crew sets up, masks off any surfaces, and sprays the foam - most residential jobs finish in a single day. Plan to stay out of the sprayed area for at least two hours while the foam cures, then re-enter once we clear you.
Free estimate, written quote, no pressure. We reply within one business day.

The City of Sherman requires building permits for certain insulation projects. We check whether a permit is needed for your specific job before work starts and pull it on your behalf if required. You do not have to make a single call to the building department.
We follow installation guidelines from the Spray Polyurethane Foam Alliance, which sets quality and safety standards for spray foam application. Asking any contractor you consider whether they adhere to these standards is a reasonable and important question.
We walk through your home, show you what we find, and give you a written quote with no obligation. If open-cell foam is not the right fit for your situation, we tell you that - we would rather give you the right answer than a sale that does not solve your problem.
