I don't know what its called, but around here we have a "Blue in color spray foam insulation" it is resistant to moisture/water. Compared to the "white spray foam" i've seen, which does actually soak up water like a sponge.

I have never used it personally, but from what i hear it's great. We have used it on some jobs, makes life a little easier, don't have to worry about vapour barrier. Just spray it on, than your ready to board it in.

Re: Spray Foam Insulation?


Hey guys,
I found this website the other day called FindSprayFoamContractors.com, it seems you can list your Spray Foam Insulation company for free and get leads. And homeowners can search for local spray foam companies to get spray foam installed. Looks pretty cool. I'm might give it a try. Lord knows, I could sure use some free leads in this economy. Let me know if anyone try's it and likes it.

Trusses run radially from center, so it would have been just about impossible to insulate with batts. Foam was sprayed by sub with no problems. Lots of trash and clean up to dispose of at end, though. Major selling point seems to be creation of sealed envelope. That is a good way to stop air infiltration but at a pretty high cost. A few boxes of caulk would probably do the same thing. I still use batt insulation in common frame construction.
Last time I looked into it, the cost difference was around 10 times as much. Looks like it's good stuff, but at a very high cost.

What about rodents? Do they or can they put some type of rodent protection in the foam?

Re: Spray Foam Insulation?


Spray foam insulation is a great product that can be suited to almost any type of application because of its varying types and incredibly performance. I've noticed one person mentioned E:zero Spray Foam earlier, this is a product I have worked with as well and is a great product. You can get foam in both open and closed cell variations so that it can be used for interior, exterior, commercial, residential, attics, really most anywhere and everywhere you need. Take a look at the spray foam products from E:zero and their website to learn a lot about spray foam insulation as a whole.

Re: Spray Foam Insulation?


Got 3 quotes to do my own roof and the difference between the quotes was amazing. Felt like I was getting screwed. I got the impression that everyone was operating a fly by night organization with little knowledge as to the technical details and if you had any problems you would never see them again. I looked at renting my own rig and doing it myself. Training was $3500 for a few days and the rig rental including product was around $10,000/14,000 to do my house (4500 sq.ft of roof area). I decided to go with EPS as my roof insulation. Sold by the board foot at around .23 cents per. bf.

This is pretty hot stuff. WALLTITE insulation. Walltite ECO by BASF. It is a closed cell medium density foam. Blown with Zero Ozone Depleting blowing agent, recycled content and natural content. The only medium density foam to achieve the Eco Log and Greenguard for Children and Schools.

Re: Spray Foam Insulation?


I used to own a foaming company. The foaming rig cost about 70K but it had heated tanks and a proportioner that could spray polyurea. I am a believer in the foam. The thing about insulation is that the R rating is establised in a lab. This R value is on the product and not the insallation. It is very hard to get fiberglas to get what is called an effective R value because there is usually gaps between boxes, framing, ect. where the air can get through. Cellulose is better that fiberglass, however being a remodeler I have yet to find a wall with cellulose that dosn't have some sort of settling. Usually there is a hard packes area toward the bottem and a gap at the top of the walls. Also water has an effect of both fiberglass and cellulose. Fiberglass holds the water and promotes mold, where cellulose gets lumpy and compact when it gets wet. Foam seals all the gaps to create an effective R value and water has no effect on the foam due to the fact that it is a plastic. Thirdly foam dosn't promote mold due to the fact that it is a plastic.

As far as foam for roofing, there are roofing foams. They are usually a 7-15 lb foam. These are usually coated with some sort of coating like a polyurea. Foam is a big investment up front but will pay you back over the years in energy savings. I used to tell the clients that if they were planning to within five years then they probably wouldn't recouperate their additional expence for the foam.

My rig burned on me due to a manufacturer defect. I never got back into it because I didn't want to go throught he expence for the equipment. However there is a system that I am looking at. It is called a spraymax system. This system only needs a 8 hp gas compressor to operate it. I havn't tried it yet, but you would have the capabilities to do both foam and polyurea. They also have roofing foams. It is a cheap way to get into the foam industry and see if it is something you want to do.

Re: Spray Foam Insulation?


Anyone have opinions on the disposable foam outfits? From what I see there are two tanks which look like propane bottles, hoses and a spray gun, and once they are empty it all gets thrown out. Appears that my cost would be around $1.00 to $1.20 per square foot with 1" thickness. I've been considering spraying the interior of my shop building (steel building with no insulation) and if I can use these disposable setups I could do the job myself.

I've used those and they work good, but you have to keep spraying once you start, otherwise you have to change the spray tips because they'll clog up. There's also a learning curve where you're going to waste a lot of material.

I can definitely vouch for the learning curve. If you have not used any kind of spray foam insulation, be prepared with a file once it dries. That stuff expands much more than you may think.

Re: Spray Foam Insulation?


ive used foam it green. The first time i did it was for a customer. He bought the do it yourself kits and asked us if we could do it. Set up was easy and spraying is easy.After feeling the effects of the foam in the house i decided to use it in my house and would never use anything else on my own personal homes. It is a lot more money though. If you spray 1" of foam it costs $1 per square foot for the material. The kits are 600 each but if you buy a couple they give you a discount.

Re: Spray Foam Insulation?


We just finished a project for NYC DEP, itr is a demonstration facility for a new process to remove nitrates from the effluent stream which cause the so called brown tide. This roof is over two tanks which contain the process & need to be kept at a constant temperature so a spray foam roof was the engineers choice. This is a Neogaurd system which is spray applied in three stages, primer, foam & top coat which is a hard coating that protects the foam & can be walked on, in fact the rating is 50 psi. Here are some pics from the start of installation;

If I am wrong, enlighten me.
Your fisrt mistake is cleaning the gun,lol. I clean my gun only on A side once a month.

Roofing Foam Starts at a 3lb foam.

Re: Spray Foam Insulation?


Hello Its Justin with Chillerz spray foam.I am.a spray foam contractor in Bradenton Fl. The cost are fairly steep in starting a spray foam company. Start up cost can exceed $200,000.00 for a truck trailer combo. As far as selling the product it's a fairly easy sell to private homeowner's. Replacing the fiberglass gives them up to 40 percent greater energy savings.Foam increases the indoor air quality by stopping allergens from entering the home. Also because the attic only runs 8 to 10 degrees Fahrenheit warmer than what the house is set at Customers see years added to the life of their hvac systems. The issue I am having is trying to sell to contractors. I just haven't had much luck in to getting them to give my company a shot. Anyone out there got any idea what I need to offer to break into this sector of business?

Excellant in homes.
We spray our exterior walls solid or combination foam / fiberglass

Closed cell we use equates to 1"=R6

No complaints
