Sean,  

Do you have a link to the slow rise foam.  I haven't heard about that approach.

 

 

Comment by Sean Lintow Sr on January 18, 2011 at 3:41pm
John in many cases, those area's are so messed up around here, we end up rebuilding the exterior walls & occasionally the floors in those "porch additions". I remember one that still had the original railing and they framed above it with 2x2's. In those cases and it is still in good condition you are probably going to have to add it from the outside (i.e. foam panels) or consider using slow rise - pourable foam if you can from the inside

I've done several audits on houses built between 1900 and 1930.  They all have an area that is now either kitchen, bathroom or both. These areas look like they were a back porch originally. 

The construction seems to be lacking, no insulation, and 3 of 4 no room for insulation, and very thin.

I've been working with taking a window or 3 out of the wall. Trying to build insulation into the wall and doing some air sealing at the same time.  This seems to just be standard 2x4 and insulate then drywall.

Does someone have a different material approach or a different approach to these types of construction?

First I hope everyone is geared up & ready for a great New Year. I did change one option on this board which is the "send message to the group" has been disabled. This was done for two reasons - number one is to eliminate anyone using this for spam purposes, and the second is if you post a message there, no one can really answer it. So if you do have a question, best practice, etc... please post it in the Discussion area above so we can help you out or even learn something new. 

 

Now if you do have a question, comment, etc... and wish to post it anonymously, you can always add me as a friend & send it to me - I will gladly post it for you.

Merry Christmas everyone & thanks for joining in the discussions & emphasizing Best Practices

Yep. We ask them what they think is going on that is causing the issue they are concerned about. We ask them how they feel about their energy bills. Mostly we listen.
Comment by Dennis McCarthy on December 8, 2010 at 6:18am
A good point ; wanting to know a homeowners expectations.
We ascertain the customers goals right away defining if they are trying to get 10% or 30% energy savings . Since getting 30% savings is more involved people appreciate choices ol what it cost to get 10- 15% Energy Consumption cuts.Ultimately its up to a home owner to decide what gets tended to . Weather stripping & use of quality Leds
Just these two combined tasks would save the ave h/o about 20% real costs- Both those tasks are something everyone can & should do.
As a solution provider I get paid to make the intel & insights I gather
come together to give people choices . Making the improvements
whether DIY or thru pros, what I think we would all agree with is that
now is the time to be making all of our bldgs more energy efficient,
using all the tools and talent we have!
Comment by John Nicholas on December 8, 2010 at 4:40am
OK! So you have a good sense of wording questions to get the maximum information. Are there other questions you have had success with?
Comment by A. Tamasin Sterner on December 8, 2010 at 3:01am
Sure thing. After a potential customer contacts us about scheduling an audit, we explain that we require certain info before we'll schedule. We require the regular: sq. ft., number of occupants, HVAC system types and fuels, at least 12 months energy use for each type of energy, and photos of the exterior. We also ask the customer this question: "How would you like your home to be different as a result of Pure Energy's audit process?" This is a better question than "Why did you call us for an audit?" because it encourages the person to imagine a better future in their home.

Tamasin, Would you expand on your concept of asking the HO how they want their house when we leave?
