Louisiana Pacific Casement Windows

Question

I have several LP casement windows( 1991 vintage) that need new weatherstripping.

The profile is very close to the Kerf Bubble Mount Seal 5/16"
(58-504) . However, I am not sure about the wall thickness on the bubble itself. Mine appears to be thinner, possibly 1/64" thick. Could you please tell me the wall thickness of the bubble material?

Thanks

The wall of your bubble does seem very thin at 1/64" (.0156"). The wall of the 58-053 is .0245", which is between 1/64" and 1/32". The bubble on the 58-053 is fairly soft and should compress to what you need.
