Seal Exclusive | Broken Window

If your window frames have blocked weep holes, rainwater gets trapped against the lower seal. Prolonged water exposure eats away at the adhesive.

If a window is forced into a rough opening or fitted poorly, the uneven pressure will cause the seal to fail prematurely. How to Spot a Broken Window Seal: The Warning Signs

The definitive solution is the replacement of the insulated glass unit while retaining the existing window frame.

This entire assembly works together to slow heat transfer, keeping your home warmer in winter and cooler in summer. When the seal fails, it’s not just a cosmetic problem. The inert gas escapes, moisture-laden outside air seeps in, and your high-performance double-pane window effectively downgrades into a basic, inefficient single-pane window. broken window seal exclusive

Check the perimeter of your windows twice a year for gaps or cracking caulk.

A broken seal is not always completely obvious. However, if you look closely, you can catch the damage before it ruins your window frame or interior drywall. Fogging and Intermittent Condensation If your window frames have blocked weep holes,

Exclusive analysis of energy data shows that a single broken seal in a double-pane window increases heating and cooling costs by —not because the glass leaks air, but because the insulating gas is gone. U-factor (heat loss rating) can jump from 0.30 (good) to 1.10 (worse than single-pane).

A rubber or silicone seal holds these panes together and keeps the gas trapped inside. When this seal tears, cracks, or degrades, the insulating gas escapes, and outside air rushes in. Top Causes of Window Seal Failure

Regularly check that the caulking around your window frames is intact and that the "weep holes" (small drainage slots at the bottom of the exterior frame) are free of dirt and debris. Proper drainage prevents water from pooling against the seal. How to Spot a Broken Window Seal: The

A window seal is the elastic sealant applied around the edges of the IGU to keep the insulating gas trapped inside and to prevent outside air and moisture from entering. Why Seals Break

If you’ve noticed a foggy, hazy, or milky appearance between the panes of your double or triple-pane windows, you are likely dealing with a . This common, yet frustrating, issue compromises the energy efficiency and aesthetic appeal of your home.

The "broken window seal" represents a catastrophic failure of this hermetic seal. When the seal is compromised, the insulating gas escapes, and moisture-laden ambient air enters the cavity. This paper addresses the specific mechanics of this failure, moving beyond general descriptions to examine the material science of sealants, the inevitability of "solar pumping," and the physiological signs of window deliquescence.

The most common cause of seal failure is the natural cycle of expansion and contraction known as thermal pumping.

Excessive heat, freezing temperatures, and poor drainage that leaves water sitting on the seals can rapidly accelerate deterioration.
