PVC greenhouse weatherstripping

| I have finally completed my little PVC house and am now stumped by the problem of weatherstripping the door and two window vents. Since I used snap clamps to hold on the poly film, all the sides of the door and windows are irregular surfaces and the gap between them and the frame of the greenhouse (where there are more snap clamps in other positions....) varies a lot.
Has anyone else successfully addressed this problem? |

| I'm using 3/8" poly foam caulk saver for the same application. Run a bead of exterior adhesive caulk along the immovable pipe, "stuff" the round foam strip into the space, and you have a flexible seal that should form fill varying gaps. It won't last indefinitely, but it should hold for a season or two and be easy to peel off later. 30' of 3/8s was $2. Also on my door it causes enough pressure (being squeezed) to make the door self closing, which I think is a good thing, but could also cause the seal to wear out a little sooner. Anyway, I hope this is helpful. I've used this stuff for a dozen purposes over the years. |

| Based on what I can see in the photo for the link this looks like the "caulk backing" material (long foam rope stuff) that I used to shove in between the bottom of the greenhouse and the foundation base. So it sticks to caulk and the caulk actually sticks to the poly film and PVC? Huh. I would not have thought so. This may be the ticket, although I will need some smaller material for the window gaps which are not nearly as large as the door gaps. Thanks! |

| Steve, that's it, a foam roap. It comes in several thicknesses as you probably know. I trimmed the plastic so I only ran the caulk on PVC. One of the Dap "adhesive silicone" caulks lists PVC in the fine print as one of the materials for the product. I used clear because my PVC is gray and the white may have looked sloppy, because, well, I can be slopping with a caulking gun. |

| Right...so I looked at the situation again with this in mind but I see a problem. BOTH the door (or window) and the frame it abutts are wrapped and have snap clamps (and not all in the same places). So attaching the "rope" with caulk to the frame solves the gaps there, but I don't think there will be sufficent flexibility to close the gaps between the door and "rope" when the door is closed. The stuff doesn't seem that squishy. Or is it? |
