Most insulation jobs add material and stop there. Spray foam does both jobs in one shot. Fill the gap. Seal it. Insulate it. Same pass. That is why it outperforms every other insulation type once a house faces real weather.
We have been installing foam insulation spray for 25 years. Attics. Crawl spaces. Wall cavities. Rim joists. Commercial buildings. Enough hours in enough homes to know that the material going in is only half the story. The other half is what we see before we open a single can of foam.
Every home in New York and Connecticut already has its own pattern. There are places that are more susceptible to moisture than others.
Spray foam is two-component polyurethane. Combining them together at the gun, react and join into a tough foam within seconds. The foam expands to fit the void it is poured into, adheres to the surface and hardens to an impervious layer of foam..
That’s the difference between spray foam insulation and all other products available in the market. Batts made of fiberglass and blown-in cellulose insulate. They do not seal. Air still moves around them, through every seam and around every recessed light. Spray foam closes those gaps in the same job.
A few things you get from foam that you do not get from other materials:
There are two types of foam that are used in houses and they are different.
Type | R Value per Inch | Density | Moisture Resistance | Best For |
Open cell | R 3.5 to 3.8 | Low, soft | Moderate | Interior walls, sound control, and large attic cavities |
Closed cell | R 6.0 to 7.0 | High, rigid | Excellent | Basements, crawl spaces, rim joists, and cold climates. |
Closed cell spray foam insulation falls in the range of R 6.0 to R 7.0 per inch. Two inches will take you to R 12 to R 14. Real performance. The spray foam insulation’s highest R-value sits in this closed-cell range, higher than any other commonly installed product on the market. At sufficient thickness, closed-cell spray foam insulation’s R-value comes paired with a built-in vapor barrier, which is exactly what basements and crawl spaces need.
Open cells cost less and expand more. It is also good for sound dampening in interior walls and at R 3.5 to R 3.8 per inch, it is still superior on air sealing compared to fiberglass.Closed-cell is the correct choice for most work in cold climates.
We tell you which one your space actually needs after we see it.
Foam works almost anywhere material can be sprayed. The spots that benefit most are the ones that other insulation handles poorly:
The common thread is air movement. Anywhere air finds its way through a structure, insulation spray foam stops it.
Two homes with the same square footage can perform completely differently. This is how we always begin our jobs:
No shortcuts. No guesses pulled from a spreadsheet.
My name is Artem Markarian. My partner Sevi Kozak and I have run this company together for 25 years. Insulation work, nothing else. That focus is the point.
What does that get you:
If your house has been hard to heat, hard to cool, or costs more every year for no clear reason, an inspection is the right first step. We will visit the space, and tell you what we actually see before any work is discussed. No pressure. No canned pitch.
The Closed Cell has an R-value between 6.0 and 7.0 per inch. Open cell delivers R 3.5 to R 3.8. Both beat fiberglass on air sealing, which is usually where the actual comfort improvement comes from.
The closed cell is denser, has a higher spray foam insulation R value per inch and is waterproof and stiffer. Open cell is more flexible, expands, and is less expensive. Closed-cell foam is generally necessary for basements, crawl spaces and cold climate projects.
Closed-cell foam will also be waterproof and will form a vapor barrier in sufficient thickness. We have a lot of experience with waterproof foam spray insulation projects such as rim joists and crawl space encapsulation. An open cell is not waterproof.
A small repair can be done using a spray foam insulation kit. Single rim joist, gaps in the windows, penetrations in the window. When spray foam insulation is needed throughout the entire attic or crawl space, it is more beneficial to have a spray foam insulating contractor to make sure that the correct insulation is applied.
The lifetime of the building in most cases. No settling, no sagging, no R value loss. That is the meaningful difference from fiberglass.
