We're offering this course monthly, using our own curriculum. One thing I've done is limit the class size to 4 people. I like to make sure they're comfortable both passing the exam and actually using these techniques in the field, and with a big class that's tough. We can do it in 3 days, both airsealing and dense pack.
Thanks Corbett, We have our training setup for a class size of 6 and we use two proctors for the testing.NYSWDA's training center does not in most cases allow trainers to proctor those people that they just trained. I train the class then two proctors test the class on the 5th day (3 trainees per proctor). We use NYSERDA's curriculm and it breaks down to this:
Monday- Building Science Module
So far so good but the props are taking a beating. Depending on the demand we may go to class size of 12 with 3 proctors on test day. I will also need an extra trainer on class days. How's the demand on your end? Is it a required certification in your state?
Corbrett, Are you using the BPI props?
We are offering WHALCI at our training facility and the one thing that I did to save the props was make the boxes and flat portions out of 3/4 melamine. The foam sticks very well to the surface. Once it's tested, the foam that is left on the reusable prop can easily be scraped off with a putty knife. I've been using the same props for over a year now and no problems.
Also, as far as I know, ILHPwES is not requiring the installers to be WHALCI certified. They are requiring the Analyst and Envelope Certs for the contractors.
Craig, Thanks. I'll keep your melamine tip in mind. Our props are beat to hell and I will have to replace them shortly.
Hey Matt and Corbett,
My name is Jason Scheurer, and I travel around the country teaching this curriculum for the past year or so and the props do take a beating. But we have noticed if you use the log sealer such as BPI recommends, the sealants come off easier. We have gone to the Melamine way of things and it works even better. I am an Independent approved Super Proctor for BPI in BA, EP, RBE-WHALC, MF. I usually have up to (12) students in the class for (3) days of training, then another proctor comes in for (3) days and tests up to (4) students per day. We will switch off from training and proctoring since this is the new protocol for BPI. If any of you guys need help with training or proctoring, I am available.
Where did you find that information "log sealer, such as BPI recommends"?
NYSWDA tested a number of release agents about 3 years ago and pioneered the use of wax emulsion (log sealer) for their props. One brand is made by UC Coatings and is called Anchorseal which works well to allow foam to release from wood. If you have a lot of area to cover, you can use a garden sprayer to apply it, but a brush is better in most cases.
They also make Bates which works well to allow mastic to release from duct work.
