Double panel storm shutter installation with brace

DETAILED DESCRIPTION In this invention, two or more window protective panels are received in parallel channels provided by supports near the upper and lower edges of the window to be protected.
The protective panels are typically plywood but may be a tough transparent plastic such as LEXAN to provide visibility and light to overcome the feeling of claustrophobia experienced by many.
The supports are conveniently aluminum extrusions and are connected to the building in one of a variety of techniques depending on the configuration of the building adjacent the window.
The supports are installed with conventional tools available to knowledgeable workmen.
Angle members are fixed to the building adjacent the sides of the window protective panels and provide two important functions.
First, they restrict air flow paths to the rear of the window protective panels thereby reducing the likelihood that high velocity wind gets behind the panels.
Second, they provide vertical supports for one or more, and preferably two, removable horizontal bars restraining movement of the window protective panels toward and/or away from the window glass.
The horizonal bars deter deflection of the panels toward the window glass and thus act as supports against rearward movement of the panel thereby effectively halving its maximum unsupported length.
After the supports and side rails have been installed, assembly of the window protective system of this invention requires no tools and can be done in a few minutes.
The home-owner needs only to insert the first horizontal bar in its support slots and then position the window protective panels in their respective channels.
The second horizontal bar is then inserted in its support slots.
One or more thumb screws are then used to clamp the panels and the horizontal bars together.
The result is a window protective covering of formidable strength.
It is an object of this invention to provide an improved window protective system.
A further object of this invention is to provide a window protective system providing two or more parallel protective panels removable received in channels in a permanent support
