Window Insulation FAQ
What are Magnetite®
Magnetite® windows are magnetically mounted and sealed windows that
are the only alternative
to replacing windows to make them more thermally efficient.
Magnetite® adds an extra layer of insulation to your windows, by using
an air-tight magnetic seal which attaches an acrylic panel to the inside
of your existing windows. The installed magnetic window will OUT-PERFORM
window available in the United States. Magnetite® Corporation is
located in Baton Rouge, Louisiana.
2. Who developed
Magnetite® was developed by Kenneth J. Foster, an energy physicist,
in conjunction with the M.I.T. Innovation Center in 1978. He was
eventually granted U.S. Patent No. 4473980. Mr. Foster combined the
concepts of using an acrylic window, like they use on jet airplanes, and
a magnetic seal, which is how your refrigerator door stays both closed
and air-tight, to create the most energy-efficient
window on the market. More than 30 years later, Magnetite®
is still the best alternative!
3. How do magnetic
Magnetite® windows mount just to the inside of the customer's
existing windows and are sealed in place by using a flexible permanent bar
magnet, just like a refrigerator door. Conditioned air cannot
leak out from the inside and unwanted hot or cold air cannot seep in
from the outside. The acrylic, a dead air space and original windows
combine to insulate better than any other window.
4. What about appearance?
Magnetite® windows can be fitted to almost any type of window,
blend well with any decor and make relatively little change in the
appearance of your windows from the inside of the room. Magnetite®
windows are invisible from the outside of the home.
5. What materials are
used to manufacture our Magnetite®
We use only the finest available materials to make Magnetite®
Windows. This allows us to offer our Limited
Lifetime Warranty with confidence.
magnetic channel which holds the window in place is constructed
of a special ABS/PVC alloy. This ABS polymer has several
qualities which make it superior to rigid PVC and other
gloss - producing a permanent satin finish, instead of the dull
appearance of PVC

greater strength and durability - this is the same material as
used in football helmets and boat hulls. A continuous strip of
flexible permanent bar
magnet is attached to the side of the framing which faces
the prime window. It is assembled using a patented channel,
rather than glues or adhesives, which could fail. This ensures a
lifetime of trouble-free operation. The Magnetic framing
securely holds a crystal-clear sheet of optical-grade acrylic
in place to complete the insulation
process, creating the most efficient system available anywhere.
6. Will acrylic yellow or
Optical grade acrylic contains no styrene or other monomers that
will deteriorate, causing yellowing, cracking and checking. Through both
laboratory and actual outdoor testing, over the last 30 years, 100%
Optical-Grade acrylic has been proven again and again not to yellow,
crack or check.
7. How are Magnetite®
The acrylic glazing and frames may be cleaned with Magnetite®
acrylic cleaner or a mild detergent (3% in lukewarm
water). Dry with a clean, damp cloth or chamois. We provide a
complimentary bottle of acrylic cleaner at the time of installation.
Additional Magnetite® brand cleaner may be ordered through our sales
department, or the customer may purchase other brands of acrylic cleaner
at most grocery stores.
IMPORTANT: Do not use Windex
or other brands of glass cleaner which contain ammonia to clean
Magnetite® Windows, as the ammonia may damage the acrylic panels.
8. Why is acrylic used in
place of glass?
Although optical grade acrylic costs considerably more than glass,
our acrylic provides many benefits:
times more energy-efficient than glass: Acrylic has four times
the thermal resistance as the same thickness of glass.
acrylic is less than half the weight of glass.
than glass: acrylic has up to 18 time greater impact resistance
than ordinary glass in the same thickness.
than glass: when subjected to a blow beyond its resistance, the
hazard of injury is greatly reduced because acrylic breaks into
large, relatively dull-edged pieces which scatter at a low
9. What about
Our windows provide a Maintenance-free, air-tight seal, year after
year. You can count on a lifetime of dependable service from the high
quality components used in manufacturing our windows. Cleaning is the
only care that is required.
10. Why are Magnetite®
Windows a better investment than replacement
windows or storm
Our patented window
system will out-perform every replacement window or storm
window system on the market today. There is no system
available that is more thermally efficient, which means the energy
cost savings with our system will be greater than any other.
Windows eliminate both hot and cold air leakage.
Our system, tested without a prime window, in a simulated
25mph wind, exceeded the U.S. Department of Energy standards for
windows by 200 times!
acrylic has four times the thermal resistance of glass, our
windows alone already insulate better than all other systems
When you combine our air-tight magnetic seal, acrylic that
insulates four times as well as glass, the dead air space
between your current windows and then consider that all of this
is added to the insulating value of your current prime windows,
no other window
system even comes close!
insulation eliminates all of the common problems which other
systems will suffer over the years, resulting in substantial air leakage
and lowered efficiency.
Our windows will never suffer from other window problems:
We have no frame and sash to shrink or warp.
We have no side tracks to loosen with repeated use.
We have no weather stripping to deteriorate, requiring periodic
We have no caulking to deteriorate, requiring periodic repair.
Our system is much more
efficient, resulting in lower
heating and cooling cost, than any other windows.
