Hard to find replacement vinyl seals

The space between the glass panes of an IGU is vacuumed to remove air and is often filled with an inert or noble gas, such as argon or krypton, to slow the passage of heat through the window unit. Inert gasses are less heat-conductive than air or a vacuumed space. However, if the seals that protect the edges of the IGU develop a break, then the inert gases can escape and ambient air and moisture can enter the space between the panes, resulting in the IGU losing its extra insulating value.

The visible symptom of this failure is the tell-tale fogginess or condensation inside the IGU unit, on the inside surface of the glass.

Not only do you lose the aesthetic value of a clear window, but the energy-saving value of the window is likely to be cut in half. The edges of the glass panes in double- or triple-pane IGU window are embedded in a sealing material.

How do the materials of weatherstripping compare?

While it appears to be one seal, it is actually two seals working together. The inner sealant is typically made of polyisobutylene PIB. Although these window seals are meant to be long-lasting and may hold up for decades, they can and do fail. Seals can be damaged by house painters using heat guns to strip paint or by homeowners using pressure washers to clean the windows.

Improper installation of an IGU window can also cause a seal to fail. But even when there is no such dramatic event, the seals are still destined to fail—eventually. Glass manufacturer PPG estimates that the gas escapes at a rate of approximately one percent per year under ideal conditions. This loss of gas can be faster if an IGU is poorly manufactured. Can window seals be repaired if they fail? There are four possible actions to take when you notice the fogginess, condensation, or wavy appearance that signifies the seals have failed on an IGU window.

Premature window seal failure indicates a defective product, and window manufacturers may offer partial or complete replacement of the IGU if the failure occurs within a stated time frame. Other manufacturers may offer prorated compensation in the case of failure, scaled according to the age of the window. If there is no warranty protection on the window, there may still be options for making the window look better. Specialty companies have captured this niche by offering defogging services that can make the window more aesthetically pleasing without actually restoring the sealed window spaces.

My back door is over 30 years some say closer to 45 years , and when I pulled the door down to start the repair I hoped like most other older and cheaper things, I had the proper weather lining for the replace job. What I found was about an inch of hollow door on one side and the other side had 1 groove and was still healthy wood.

What I did was fill the hollow part with wood glue and wait 2 days. Now the door works and looks great. Just to Clarify something…. I cannot put the tube side to the Outdoors, since My door swings to the inside. You may want to let the others know about that necessary option. Thank you for a very documented help. I was planning to call someone to fix it for me, but after reading your instructions I feel quite confident that I will be able to do it on my own.

We bought a new home and the weather strips on the outside glass doors seem fine but after opening it two or three times it sticks out a couple of inches. I am constantly pulling the thing back in place. Should their be a cap on the end or how do you keep them from crawling out? The weatherstrip spline may be worn out or missing some screws. The problem with my door is that it has a single opening which runs down the center of the bottom of the door.

The old weatherstrip slid into this slit. I cannot find one that fits it and I cannot find the manufacturer of the door. It is a good clad door and I think about 15 years old. The center kerf snap-in door bottom sweep appears to be discontinued. A wrap-around door sweep should work. Frost King.

Has metal strip and is hard to cut. Any ideas what to use to cut this with? Cut the door sweep with a hacksaw. Do yo know where I can find such a sweep? Maybe the M-D Building Products will fit? I have double exterior doors with old weatherstripping. One door is stationary. The stationary door should have retractable bolts along top and bottom edges for opening. I just finished changing my front door seal. Saved myself some time and trouble by not taking the door off.

Took the old seal down to Lowes and found a suitable replacement. Started the new seal in the door kerf at the hinge side and suing wood wedges had it installed withing a few minutes.
