Home insulation.

[Oletimer]

Wondering if anyone has ever used a company called BayState Foam, Salem, NH to insulate their house or cottage in New England? They use what they call a tripolymer injection foam process made by C P Chemical. It is supposed to be completely safe even though a foam. We all know the history of the bad kind of foam! We all know the price of home heating oil now! This is supposed to save 30% to 50% in costs.
Just in case anyone is interested they have web site at Baystate injection foam.com.

I'm considering and hope one or more have done this same insulation and what they think of the results and the company.

Thank you very much.

Oletimer.

Elsewhere there have been discussions of this type of product. Go over to www.greenbuildingadvisor.com and do a search on "tripolymer injection foam." Among the various discussions is this one: http://www.greenbuildingadvisor.com/...healthy-choice.

You could be better off having dense-packed cellulose blown in.

Looking at new construction around here.

A thin layer of foam is sprayed. Then standard fiberglass insulation is used.

If doing interior roof make sure all is crystal clear as to any ventilation if required.

How can they say 30-50% that's a totally subjective thing. Will they take last year's bill and simply say it will be 30% lower?? If it isn't they'll say cause you kept your thermostat higher. Many window companies also "guerantee" this but I'll bet just about none ever pay out anything on their promise.

spray foam offers a R-7 per inch traditional old fiberglass for example on a 2x4 wall you can get R-11 with spray foam 2 inches thick or sometimes higher depending on plumbing and electrical you can achieve a R-14. and yes on roof systems typically you dont need to vent because spray foam is a closed cell product. good luck

[DickR]

The R value of spray foam depends on the type. Some closed-cell foams ("2-lb foam") may start at 7 per inch but after some offgassing over time ends up at around 6.5/inch. Water-blown closed cell foams typically start and end at 6/inch. There are a number of open-cell ("half-lb") foam products around (eg. Icynene), for which the R value typically is 3.6-3.8/inch. Blown-in cellulose has a nominal R value of about 3.6 or so. A shortcoming of all insulation materials blown or injected into an existing wall is that it's easy to miss parts of the cavities that are blocked off by framing members.

For all cavity insulations, the center-of-cavity total R value is only part of the story. The R value of framing lumber is only R 1 to 1.2 per inch, and the exterior shell of a framed house typically is 20-25% solid wood! The "thermal bridging" of all that wood reduces the "whole wall" R value considerably from what the center-of-cavity R value is. One technique for mitigating the thermal bridging of the framing lumber is to apply a couple of inches of rigid foam to the exterior, but that involves removal of siding, removal and reinstallation of windows to bring them out to the new outer plane, and reinstallation of siding.

Call the electric company for an energy audit. The engineer audit the house and made great suggestions. The engineer will audit new construction as well as existing. The suggestions are well suited to our environment.

My 1987 condo received 3 stars after improvements and inspection. I never spent more than $130 a month for natural gas. The gas provides domestic hot water, cooking and clothes drying as well as heat for a 1100 sq feet condo.

A house I built two years ago exceed Five stars. The current owner heated the 2500 sq ft house with propane for less than $1000 a year. The propane also provide domestic hot water, cooking and clothes drying.

Thanks to all who responded re the foam injection process etc..

I think this injection foam process is not that well known as it's kind of tough to gather information.

Thanks BroadHopper, I'll call the electric company. And thanks to Dick R-I did check out the green company web site.

Thanks to all for your responses. I have decided to go ahead with the injection process if a few things are satisfied for signing the contract and should let you all know the ultimate outcome and how good it insulates. May be mid to late October.

Sorry if I did something incorrectly to cause this thread to be moved! I don't post too often and am not used to how things work here. Might it be due to my using a different title? Thanks.

...but being in the home, cottage, or land maintenance forum seems appropriate. It it started out in the General forum, that may be reason.

I think you are doing just fine...just look at all the forum titles to see under which one your post (new thread) may best apply.

Above all...smile ...your doing fine from one old timer to another.

Don't overlook the actual heating system for savings.

I have a Buderus boiler that has cold start, outdoor reset, and superstor hot water tank (has its own zone from boiler).

Way, way more efficient than any contractor boiler. Stick with fiberglass insulation (combo with blown in attic) with a top tier boiler and don't look back.

[dpg]

I did the mass save audit (of course in mass ) not sure if NH offers this. Got the attic "air sealed" and new blown-in insulation for around 600.00 the whole job was quoted around 2,500 they offer up to 75% savings. Also replaced a 35 yr old Boiler with a new high efficiency model and took advantage of their interest free loan. Last winter my gas bill dropped by as much as the loan is, the Boiler is literally paying for itself right now. Last winter was also very warm so we'll see this winter.
