The Confusion Explained: Everything to Know
No question gets asked more often as: inside or outside? The confusion remains reasonable — both almost identical in the catalog, yet the two are opposites. Inside closures tuck inside the high points. Outside foam closure strips fill on top of the panel, filling the opposite spaces. Pick the mirror image, and the foam just won't fit.
As a trusted provider of closure strips, we keep every project straightforward. This overview walks through the confusion.
Inside, Outside, Top, and Bottom
Inside foam closure strips seal under the high points, while outside strips seal the top of the panel. These come as mirror images — and never the same part. And on a deck assembly, top side foam closures and bottom side foam closures seal both sides. Know which you need, and the closure works.
