Is open-cell spray foam right for your West Lafayette house?

Open-cell foam insulation is a soft spray foam we put into attics, rooflines and walls in West Lafayette. It swells to fill the cracks and stops air slipping through, so drafty rooms and a hot upstairs even out.

Most calls start with a cold room over the garage, an upstairs that bakes in July, or a power bill in an older house that doesn't add up. Foam isn't always the answer, and sometimes closed-cell foam, the dense kind that blocks moisture, or plain air sealing fits better. The price moves with how many square feet we're covering, how thick we spray, whether old insulation has to come out first and whether the foam needs a coating on top. The schedule turns on whether the wood is dry, whether the weather suits the foam and whether your job needs a permit. I'll come look and give you your own figure at the estimate.

How we install open-cell foam insulation

Open-cell stops air well but lets moisture through, so before you pick it I'll talk with you about where it's going and whether it needs a coating on top. Next we check that the wood has dried to the level the foam maker recommends and that the weather and temperatures suit the foam, and if they don't, we move the date rather than spray anyway. On install day our crew sweeps dust and debris off the roof boards and framing and covers the wiring and mechanical equipment, so the foam sticks where it should and nothing gets buried. Then we spray to the thickness we agreed on and clean up after ourselves.

Foam in the attic won't fix a damp space under the house, so if the ground down there is wet, we'll look at a crawl space vapor barrier first or alongside it. Landlords and small business owners call us too, and we handle that work through our commercial insulation service.

Foam under the roofline

This suits a house where the furnace or ductwork lives in the attic, because foam on the underside of the roof brings that space inside the part of the house you heat and cool. When an existing attic is converted this way, the industry guide says the old insulation on the attic floor should come out, which clears smells left by past birds and rodents and adds insulation removal to the job.

Air sealing with a loose-fill top-up

Foam costs more, and if nothing mechanical lives in your attic, sealing the gaps around pipes, lights and the hatch, then topping up with blown-in insulation, loose fill blown through a hose, usually gets you there for less. When that's the better buy, I'll tell you so.

Open-cell foam insulation permits in West Lafayette

The city's Building Department issues residential permits, and the city says you need one for any alterations, repairs or changes to existing buildings, and for structural work. Whether your foam job falls under that is the city's call, so we check which office covers your address and handle the permit side with that office when your job calls for one. Review usually wraps up within 10 business days once the city has every required application document. The city won't issue a permit until the contractor's bonds are on file, so that's worth asking any contractor about. If your house is outside city limits, the city sends owners to the City of Lafayette or the Tippecanoe County Building Commission instead.

On jobs here we see a lot of older houses with thin, patchy insulation, rooms over the garage that never warm up and attics with ductwork running overhead, which is where foam under the roofline earns its cost. We do the same work across the cities around West Lafayette, including Lafayette and Crawfordsville, along with Frankfort and Monticello.

Questions about open-cell foam

How much does open-cell spray foam insulation cost in West Lafayette?

Around Lafayette, open-cell spray foam covering 1,000 square feet at 3 inches thick usually runs about $1,700 to $2,500 per job. That's the going rate in the area for that size, not a quote from us. Each inch of open-cell gives about R-3.6, the number for how well insulation slows heat, so the thickness we spray sets both how much it insulates and a good part of the price. Your own figure comes from the estimate once I've measured the space.

How long do we have to stay out of the house after spray foam goes in?

You, the kids and the pets stay out until the house has been fully aired out and cleaned, and you come back at the foam maker's re-entry time, the point they say it's safe to be inside again. The chemicals in spray foam, including isocyanates, can cause asthma, lung damage and skin and eye irritation through vapors and dust during and after spraying. We'll give you that time before the job so you can plan where to go.

Does open-cell spray foam need a vapor barrier or coating over it?

It can, because open-cell foam doesn't stop moisture vapor on its own. It lets more vapor through than closed-cell, so by itself it doesn't work as a vapor retarder, a layer that slows moisture moving into the wall or roof. One industry guide says a covering or coating may be required over it in cold climates, which adds a step and some cost. If your spot needs one, it'll be written into your estimate.

Who should install open-cell spray foam insulation in my house?

A licensed professional applicator should, and that's what federal building guidance recommends for spray foam. The foam is mixed and sprayed right there in your house, so the person running the equipment matters more than the brand on the drum. Ask any contractor you're considering how they prep the space and when you can come back inside.

How do I get my house ready for an open-cell foam install?

Clear out whatever's stored in the attic or the room we're working in, so we can reach the framing and keep your things out of the spray. I'll walk you through the rest at the estimate, including what we'll cover and where you'll stay while we spray.
