Semco weather stripping

Thanks for posting. Semco windows can use many different weatherstripping types. To know which you need, you will have to remove a sample and show us the end profile. That cross-section view, along with dimensions, will narrow down your choices. In the time being, see our selection of weatherstripping here.

Thanks! We unfortunately don't sell this exact seal. I wonder if our 58-053 can work as an alternative. This has a similar kerf and should install the same way, but it has a bubble instead of a flap. My concern there is that our part may be too big, but you can review our diagram below to verify.

That could potentially work, but my concern there is that the two halves of the bubble won't then be stiff enough to properly insulate your window. I would try it as-is first to see how well it works, then consider adaptations from there if necessary.

Hello,

Unforutnately, we do not carry a match for the seal shown in your photo. Our closest option would be the 58-055 bubble seal with an offset kerf base but I'm not confident that it would work for your application. Review the dimensions below and see what you think.
