Why are you pulling air from basement? I think if you circulate in the house it's better.
Thanks for sharing

@vpbubbies You could use dry wall on top of the foam to act as a thermal barrier but that would also increase the weight somewhat, or you could build the unit with a wooden inner and outer skin with a foam core, less complex would be to just pony up the money and get god quality foam from the outset.

Excellent presentation, clean product... very time consuming.

@vpbubbies You should use fire resistant foam, high end foam will be resistant to heat.

Hi, Looks pretty simple like you do it, i'm sure its more work than it looks like:-)
you said it was 20 degrees F? How cold would this work? would it work at -20 to -25 celcius. right now it 17.7 degrees F
i used a heat resistant silicone. the tube said it was good to 300 degrees Fahrenheit

did you have any issues with the foil-backed foam "melting" ??? I too used foil-backed foam, but it melted the first day and completly deformed itself. Just wondering.

@vpbubbies no melting on mine. I used a good quality polyisocyanurate from Dow

Hi, well done!
What is the airflow and what is the cubic feet of the room?

with a 4" outlet the air flow is about 900' per minute that would be 80 CFM. The room I have it in is 12X12X8 but has 3 large doorways leading to three other rooms about the same size. I estimate it produces4000 BTUs of heat per hour and runs for about 520 per year

Do you just let the fan run all the time?

The fan is turn on and off by a snap disc control. When the temp inside the unit get to 110 degrees it turns on the fan and when it goes down to 90 degrees it shuts off.
