Get Your Free EstimateClosed cell spray foam insulation? It’s basically a two-part liquid mix that, once applied, puffs up into a tough, solid foam. This stuff creates both an air and vapor barrier, which is pretty neat. Our service covers everything: we get the surface ready, spray the foam just right into your walls, attics, crawl spaces, or rim joists, and then clean up afterwards. The goal, of course, is a complete and effective thermal envelope for your home.
We always kick things off with a detailed site assessment. That helps us pinpoint exactly where you need insulation and get the whole area prepped. Before we spray, we mask off anything nearby, make sure there’s good airflow, and double-check that the surface is clean, dry, and free of any gunk. We spray the foam in layers — usually an inch or two at a time — which gives the chemicals time to react and expand properly. That’s super important for hitting the right R-value and density. And for consistent pressure and temperature, which is key for the foam's chemistry, we rely on our Graco Reactor equipment.
For homes right here in Box Elder, closed cell spray foam is especially good. Why? Well, our temperatures jump around a lot, and we get those strong winds, don’t we? Its high R-value per inch — typically R-6.5 to R-7.0 — means you don't need as much material to get really good thermal resistance. This makes it perfect for tight spots like rim joists or cathedral ceilings. Plus, the foam’s rigid nature actually adds a bit of structural strength to your wall assemblies, which can be a real bonus for older homes or new builds.
Homeowners often ask about curing time and off-gassing. Good questions! Closed cell foam usually cures pretty fast, becoming tack-free within minutes to an hour. We always make sure the area is well-ventilated during and right after we spray to clear out any airborne particles or smells. Once it’s cured, the foam is inert, meaning it won't pose any chemical hazard. We also deal with concerns about electrical wiring and plumbing, making sure we maintain proper clearances and use the right sealing techniques to keep everything safe and sound.
Box Elder's weather can be pretty wild, right? We get those really cold, dry winters and then hot summers. Good thing closed cell spray foam offers an R-value of R-6.5 to R-7.0 per inch. That's way better than old-school insulation like fiberglass batt, which only hits R-3.0 to R-4.0 per inch. Because it resists heat so well, your furnace and AC won't have to work as hard, and that means lower utility bills all year long.
The foam itself is dense and rigid, so it doubles as a strong air and vapor barrier. This is super important here in Box Elder to keep moisture out, which otherwise could cause mold or mess with your indoor air quality. By stopping air leaks, it gets rid of drafts and keeps your home's temperature steady, making things much more comfortable when the weather gets extreme.
And get this: closed cell spray foam actually makes your building stronger. That's a real plus for homes in places like ours that might see high winds or even seismic activity. Plus, pests don't like it one bit—it's not a food source for them, and it forms a solid wall that rodents and insects find tough to get through. Just another layer of protection for your Box Elder home, wouldn't you say?
We meticulously mask off all surfaces not being sprayed, including windows, doors, and flooring, using plastic sheeting and tape. This protects your property from overspray and ensures a clean work area, which is essential for a professional finish.
Before application, we inspect the substrate for cleanliness, dryness, and structural integrity. Any dust, debris, or moisture is removed, as proper adhesion requires a clean, dry surface, which impacts the foam's long-term performance.
Our certified technicians apply the two-part closed cell foam mixture using calibrated Graco Reactor equipment. We apply in controlled lifts, typically 1-2 inches at a time, to ensure optimal expansion, density, and a consistent R-value across the entire insulated area.
Once the foam has cured and hardened, any excess material is carefully trimmed flush with the studs or joists. We then conduct a thorough cleanup, removing all masking materials and debris, leaving your property tidy and ready for subsequent construction phases.
