Signs That You Need to Replace Dual Pane Windows
                     SIGNS THAT YOU NEED TO 
REPLACE DUAL PANE WINDOWS 
Dual pane windows offer benefits that 
include making your property more 
energy-efficient. 
This style of window has 2 panes of glass 
with gas sealed in between them.
The space between the panes serves 
as an insulating layer that helps 
to maintain the temperature of your home.
Over time, the seal between the panes 
can break. 
The glass or frame around the window 
can also get damaged. 
Watching for these signs lets you know 
when it is time to plan for a window 
replacement.
CONDENSATION BUILDS UP 
BETWEEN THE GLASS PANES
One of the biggest warning signs of a failing 
seal is seeing fog or condensation build up 
between the layers.
This is a sign that outdoor air is getting 
inside where the temperature difference 
leads to a build up of moisture.
In addition to being unsightly, this means 
that your windows are no longer serving 
their primary purpose.
OUTSIDE NOISES ARE MORE 
NOTICEABLE INDOORS
The insulating layer between the two panes 
also serves as a buffer 
to outside noises. 
In most buildings, you can usually hear 
some noises.
For example, it is hard to completely muffle 
the sound of a loud truck driving by. 
Think about what is normal for your home 
or commercial building.
If you find that you are hearing more noise 
than you once did, then this could be a sign 
that the seal is breaking down.
RISING HEATING 
AND COOLING COSTS
Sometimes, the first sign of a faulty 
window is lower energy-efficiency. 
You might not see condensation building 
up just yet, but you could notice a higher 
electric or gas bill.
Replacing poor-performing windows 
with ones that are in good condition 
could help you to lower your home’s 
energy costs.
FEELING DRAFTS OF AIR
A poor seal around the panes allows 
air to come inside. 
You can run your hand around the 
perimeter of the frames to see if you 
feel any air. 
A professional inspection can let 
you know if the air is coming through 
a replaceable part of the weatherstripping 
or a broken seal between the two layers 
of glass.
VISIBLE DAMAGE 
TO THE PANES OR FRAMES
Once the gas escapes through a bad seal, 
the two panes can sometimes collapse 
inward or develop noticeable distortions. 
Cracks are common when this happens. 
Any visible damage to the glass 
compromises it’s insulating qualities.
The frames around the glass play a role 
in keeping the window sealed.
Wooden frames are susceptible to rot. 
A fully framed replacement is an option 
that lets you upgrade to stronger 
materials such as aluminum or vinyl.
THE DECORATIVE GRIDS 
ARE FALLING DOWN
A failing window can also impact the curb 
appeal of your property. 
Many dual pane windows have decorative 
grids between the layers of glass.
The materials holding these grids in place 
can sometimes degrade. 
When they do, the grid lines will fall out 
of their desired places. 
Fixing this issue would involve needing 
to break the seal between the panes. 
In most cases, a replacement
is recommended to restore
the appearance of your property 
without sacrificing the window’s integrity.
The windows on your home or commercial 
building should last for many years with 
proper care.
