I happened to read the document "basement insulation systems" which I got from one of the links in this forum. It says "Sealant at corner of bottom plate and subfloor or gasket under bottom plate". Although I think it makes sense that you would seal the bottom plate with the floor, I haven't heard about this until now. I'm wondering if anyone has done this and if so with what. What sealant and what kind of gasket is available?

Thanks,

Yankee,

Not sure what you read or if you are referring to traditional methods of wall framing in a basement but normally, what is required is the following,

All wood in contact with concrete or masonry must be treated for direct contact or be wood of natural resistance to decay usually Wood Treated. or if done at all is redwood or cedar.

Hope this helps!

 

Hi Doug,
Please check out this document.

On page 13 please see " Figure 14 Additional Interior Basement Insulation".

It just seemed a good idea to seal the bootom plate to the concrete floor. Don't ask me why 'cause I haven't got a clue. Just a thought.

Thanks,
Yankee

 

Yankee,

I guess if you wish to do so, it's totally up to you. I see no reason to do so but Building Science is a testing and research facility. . What they may recommend or suggest may not be allowed per local or IR Codes. You do what they say at your own risk.

I can only provide information as to what is currently approved for use today. All the research in the world doesn't make application legal but Building Science does do research for the U.S. Dept. of Energy. In other words, they are a private enterprise. Their test results are then evaluated and if considered viable, they get implemeted into the Building Codes after much review.

Good Luck!

 

Thanks, Doug.

Yankee.
