Wood Beam thru brick cavity wall

Wood Beam thru brick cavity wall

Wood Beam thru brick cavity wall

(OP)
I have a wood beam that needs to penetrate a brick cavity wall to bear on the backup. What precautions should I take to prevent the wood beam from rotting out prematurely?

I was thinking of coating the end of the beam with green treat and wrapping it in building paper.

RE: Wood Beam thru brick cavity wall

Could you consider using treated wood for the entire beam? Even with CCA use being restricted, there are other options (ACQ and CA) or maybe the more environmentally friendly borate compounds (if the wood staying wet is not a concern).

If using treated wood is possible, take a look here

I would think some felt paper would help.

RE: Wood Beam thru brick cavity wall

The code would require you to leave a 1/2" airspace on the beam end, sides and top.  In addition a bearing plate should be used to serve as a vapor barrier.

However as SlideRuleEra indicated if you have high moisture content conditions such as you might have with a canopy you might consider treated glulams.

A non-hydroscopic bearing material (Delrin, teflon, ect)could be used.
