Weatherstripping and gaps

Postby lfhoward » Tue Jul 17, 2018 11:05 pm

Hi All,

I’ve had some issues keeping my door sealed. I used this excellent plan I found on here to build and hang the door, with a 1/8” gap between the door and the door jamb molding and both an inner & outer seal.

The only problem is, the door is so big that the gap around it changes depending on the weather. In humid conditions, the gap can be 1/4” to 1/8” depending on the location.

I had originally gone with 1/8” tall, 1/4” wide foam tape style weatherstripping, and doubled it up in the problem areas. This has worked somewhat, but water still leaks in when driving in the rain or during strong storms. In particular, there is a small gap where the tape steps up from one to two layers thick.

Is there a different, better kind of weatherstripping that would seal variable thickness gaps? Ideally I’d like it to be compressible down to 1/8” but tall enough to fill 1/4” gaps.

I’ve been looking at this as an option. Thoughts? Has anyone used this?

Thanks!

Yes, I have used 'D' profile weather stripping and have been very happy with it.

Something like this might work for you.

Here’s a video from Trimlock about choosing the right seal size

https://www.trimlok.com/rubber-extrusio ... -trim-seal. Click the “installation “ tab to get to it.

It says put lumps of clay in the door jamb to measure the gap then pick a seal that ends up crushed 25 to 50 percent

Have used that exact 5/16 D style seal on my Scotty door, very happy with it.

Thanks everybody for your responses. I think when I redo the weatherstripping I’ll try the D-shaped EDPM gasket. Fingers crossed!
