I’ve been planning to make a new exterior front door for my home, to go along with a larger renovation. I have read up on the approaches to making the door, but what I can’t seem to find is much literature or advice on weatherproofing. I know about the aftermarket weatherstripping from companies like Randall, but im more interested in the “integrated” approach, such as with metal interlocking strips that I see on some doors.

Anybody have thoughts or source material to read on weatherproofing a new custom door? And vendors!

Thanks

Metal interlocking weatherstripping (in brass or aluminum) still exists, but isn’t used much any more because

A: it is time-consuming (and therefore expensive) to install.

B: It is very unforgiving of slight shifts in the way the door hangs.

C: It requires some special tools

D: It doesn’t seal against air infiltration very well.

Door manufacturers use all kinds of weatherstripping systems, some proprietary. The company I work for generally uses kerf-in Q-lon—which works well but isn’t as “clean” looking as the metal interlock. We have used some of the “vinyl bulb” products that are lower-profile with success.

I would recommend against the interlock, and use something replaceable, like Q-lon or a vinyl bulb. My .02
