What to look for in vinyl windows.
I have been supplying and installing vinyl windows and doors for over 35 years in 100's of homes. I have built a reputation for using windows with quality, value, long lasting and the best installation around. I don't just talk the talk; I also walk the walk. With exceptionally high standards. I want the same with the windows and doors that I sell and install. I hope this helps in making an educated choice with choosing
the best windows for your home and needs.
​
One of the first things I look for is the color of the vinyl. Is it a bright white or a dull, grayish, dirty white? Or an off white or kinda yellowish?
Bright white is a sign of quality. These windows have a compound added
to the vinyl: Titanium Dioxide, which makes the vinyl stronger more
heat/cold resistant, not brittle and weak, which is important considering our winters and summers. This vinyl is easy to keep clean, lasts longer
and won't discolor over time. Look for bright white not off white.
This sticker should be on your windows. It gives us the
efficiency ratings that we need to determine how well
the window will perform in winter and summer.
​
If the windows are not Energy Star certified, look for another window.
The ratings or numbers will tell us how efficient the glass is.
Look for the overall Energy Rating. It should be 34 or higher. The higher the number the better. The issue I have with this testing is although it does
give us glass ratings, the frame does not really come into play. As long as the glass meets the minimum standards and the frame is weak, the window can receive the Energy Star rating. I know of a few of these window manufacturers. They received the Energy Star certification
but the frame is weak, brittle and are usually off white. One more
thing, some windows will have an Energy Rating of 30
and still receive certification, these windows are not
going to perform very well in summer or winter.
Remember 34 or higher.
​
U Factor or U value;
Measures the amount of heat that can escape through the glass.
The lower the number the less heat escapes. In cold climates, Low U values will reduce heating costs. Look for a range 0.1-2.0
​
​
.
Solar Heat Gain Co efficient;
Measures the amount of solar heat gain that can pass through
the glass. A lower number means less heat gain, Great for cooling in the summer and stops the sun rays from damaging furniture, floors etc. A higher number means more heat gain. Great for passive heat from the sun in winter.
Look for a mid-range number. 0-1.0
​
​
Visible Transmission VT
Measures how much natural light passes through the glass.
Look for a mid-range number 0-1.0 Less artificial lighting
is needed reducing utility bills.
Air Leakage;
This measurement does include the frame and the
weather seals It factors in how much air escapes
or enters through cracks, edges & the weather seals.
Typically, Energy Star accepts a window that
rates equal to .3 or less. Look for less than 0.3.
This does not look at the quality of the vinyl
frame or the quality of the weather stripping.
only if it passes the air test
These windows won't stand the test of time.
Insulated Frames;
While in theory this make sense. Some window companies
have to insulate their frames to pass Energy Star standards.
Usually, the improvement is minimal just enough to pass.
These windows either have to upgrade the glass, which
can be costly or a cheaper method is to insulate part of
the frames. I know this as a fact because our economical
line window had an Energy Rating of 30. In order to
be energy efficient, I had to upgrade the
glass which meant they weren't economical anymore
to reach the Energy Rating of 34. The manufacturer
found a less expensive route and added insulation
to part of the frame to pass the minimum
requirements.
My window of choice;
I prefer to use a window that I have used for over 20 years.
The vinyl is bright white, strong, multi chambered frame
for strength and efficiency. The frame is co-extruded
with 55% fiberglass and vinyl. The only window available
with the best of both worlds.
Stronger than vinyl, not as expensive as 100% fiberglass. Energy Ratings start at 34 standard.
No costly upgrades needed. Low E glass and
Argon Insulating gas and exceeds Energy Star ratings.
You will never change this window as long as you own
your home. Combined with my advanced installation
style, you WILL save money on heating, air
conditioning and the first thing you will notice is
a huge reduction in sound proofing.
A lifetime transferable warranty and a great labor
warranty. The best value in vinyl windows.
