Information on the WinDoor Products

The features listed below depict some of the details that separate a
WinDoor sliding glass door or window from others. As an example, our
tandem Delrin" wheels set in stainless steel housings translate into
very quite, smooth and easily operating panels. This feature coupled
with our dual point mortise lock, also in stainless steel, means that
in coastal applications the problems caused by salt air and abrading
sand are eliminated. Our unique application of hidden wool pile with
center Mylar fin weather barriers, offer not just airtight performance
but the aesthetic considerations dictated by thoughtful design.

Dual fin weather stripping:
It not only keeps the weather out with its double barrier, WinDoor
designers have concealed it. You know it is working each time you
operate the door and hear the quiet SWOOSH of wool pile against the
frame. The weather barrier while not seen quietly reassures you each
time the door is opened or closed.

Interior and exterior pull handles:
Our doors have real pull handles, not the kind with a little slot that
break your nails or makes sliding the door nearly impossible. Our
handles will be appreciated every time the door is opened or closed.

Custom color paint finishes:
"Any color you want as long as it's...any color you want." We offer 
industry leader PPG, painted finishes. Our standard AAMA 2603
electrostatic applied paint is Duracron. We can also provide a better
quality finish of Duranar (70% Kynar) which meets AAMA 2605. Whichever
you select, both finishes meet the highest industry standards for color
retention, resistance to chalking and film integrity. In addition, we
can provide different interior and exterior colors. As a home owner or
as a designer you will have the color you want outside your home and
your decorating theme inside will not be restricted.

Hidden fasteners:
Ours are unique in the industry and very desirable from an aesthetic
point of view. The real benefit is in the appearance of the door. Clean
uncomplicated lines that let you appreciate the beauty of the door, not
unsightly attachment screws.

Primary and secondary dual point mortise locks:
A dual point locking mechanism is the most secure lock used in the
industry. Ours features an anti-slam device. It is our standard lock
located at the handle and secures the door panel with two CLAWS that
lock in both an up and down direction. An identical secondary lock is
provided on our doors that are taller than eight feet. And of course
the secondary lock is available as an option on doors that are not
eight feet tall. The secondary lock is located six feet up from the
floor. Should the grandchildren come over and you are unable to keep
an eye on them at all times, it is comforting to know that the
secondary lock is out of their reach.

Laminated glass:
Besides increasing the strength of non-laminated glass to act as a
barrier to the wind blown debris of storms, laminated glass also
reduces transmitted noise by more than 50% over standard annealed glass.
Additionally, the PVB interlayer contained in laminated glass filters
the sun's ultra violet rays thereby blocking these harmful rays from
fading fire furniture, draperies and carpeting. This extra benefit is
particularly appreciated in intense sunny climates.

Insulated glass:
You already know about the protection that results from using
laminated glass. Additionally, when laminated glass is used as
part of an insulated glass unit, the benefits go beyond just
impact protection. The result is lower energy costs, better
condensation resistance and significantly less transmitted noise.

Delrin' tandem wheels:
Our engineers have specifically designed these wheels with stainless
steel housings and stainless steel ball-bearings to be whisper quiet.
Delrin is an ABS/acetal co-polymer and has excellent dimensional
stability. The wheel has been designed so that it's contoured to
perfectly match the aluminum track that it rides on. This results
in a wheel that tracks perfectly without lateral vibration and
contributes significantly to the ease and smoothness of operation.

Dual interlocks at the meeting rails:
Imagine two tubes parallel to one another, such as the vertical panel
stiles of our sliding glass door panels. If they are not physically
linked together in some way a force or load on them will cause them
to separate or roll apart. Two rows of INTERLOCKS have been
incorporated into our panel stiles so they combine to form one strong
element. The interlocks assure that the panels actually lock together
to resist any force that is placed upon them. Now imagine that this
force is one created by the wind from a hurricane and you can
appreciate the importance of this structural feature.

Should design pressures require product reinforcing to meet the loads,
you will appreciate that we use concealed aluminum bars inside our
vertical stiles. As a result we maintain our products appearance whether
reinforced or not. As a long term consideration, unlike those who use
steel for this purpose, you will not experience pools of rust under
your doors.

Two part sill and hidden fasteners:
The two parts are the SILL PAN and the SILL TRACK or COVER PLATE.
The sill pan is anchored to the floor while the jambs and head are
attached to the rest of the opening. At this point the fasteners
are exposed, allowing a building inspector to verify that they are in
their proper locations. Because the sill track covers the sill pan,
the installers can apply extra sealant over the fasteners, ensuring a
water tight installation. Another advantage of this two part system is
the clean appearance of the sill track and jambs, the finished product
really looks finished.

Sill risers and protection from water:
Our door sills have unique designs to meet stringent water test pressure
requirements. The AAMA 101 standard prescribes that a door's water test
pressure must be a minimum of 150/o of its positive design pressure. We
have developed a unique sill for our Sliding Glass Door. Because each
application requires a different design pressure, we have a variety of
sill heights to meet or exceed these various conditions.

Weather-stripping:
The benefits of using silicon impregnated wool pile, separated by a Mylar
film, are well documented and it enjoys wide usage throughout our industry.
The key to superior design and performance is in the placement of this
weather-striping. WinDoor uses double rows along all four edges of each
glass panel. The result is superior resistance to air infiltration. We
have succeeded in that, not only do you see nothing of the
weather-striping but you hear nothing of the wind blowing outside.
