     BACKGROUND OF THE INVENTION  
      During recent hurricanes billions of dollars were lost in Florida and other coastal States to extreme forces, high winds, rain and blowing debris. Of this, a great percentage can be attributed to losses of residential pool, lanai screen cages enclosures and lost or torn window screens. As a result insurance, residential and commercial property losses are staggering and well into the billions. The building and maintenance of lanai screen enclosures is a multi-billion construction industry in the US each year. Scrap aluminum prices are at a 15 to 20 year low locally with the sudden influx of screen enclosure debris. Single panels screen replacement can cost property owners approximately $100.00 per panel. A two story cage replacement can range from $40.000 to $70.000. During the next 20 years it has been predicted by weather forecasting and government agencies that Gulf and Atlantic coastal residents can expect significant increases in the occurrence, size, strength and frequency of tropical storms and hurricanes due to a trend in rising ocean temperatures. This year&#39;s (2004) storms have devastated all effected property owners and communities and cost the insurance industry greatly because of property losses due to storm damage.  
       
     BRIEF SUMMARY OF THE INVENTION  
      The inventive replaceable screen involves the use of VELCRO wherein either the loop part or the hook part of the hook and loop fastener system is attached to the conventional aluminum frame of the lanai or the pool enclosure where normally the screen material is directly attached by way of splines. The known spline now attaches a strip of the VELCRO material to the frame and the other part of the VELCRO material is attached to the edge of the screen material. The screen size is predetermined so that when the hook and loop strips are attached to each other, the screen material will tightly extend between the frame components. 
      1. The replaceable screen and construction system are child and accident friendly. They eliminate screen tears from accidents by “giving in” while being easily put back in place by the property owner without having to have any skills or tools.     2. The replaceable screen can be manually removed before tropical or hurricane force winds arrive and stored in a safe place. The screens can be put back in place without the purchase of new screens, materials, tools or a professional installation.     3. The replaceable screens will “blow out” or “give in” with a 60 to 80 MPH wind without damage to the material itself and reinstallation after the storm.   

    
    
     BRIEF DESCRIPTION OF THE DRAWINGS  
       FIG. 1  is a representation of the prior art;  
       FIG. 2  shows hook and loop fastener attached with a spline;  
       FIG. 3  Is a different embodiment of attaching a spline to a vertical column;  
       FIG. 4  is another embodiment of attaching a spline to a vertical column;  
       FIG. 5  is still another embodiment of attaching a spline to a vertical column with the spline directly attached to the screen. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION  
       FIG. 1  is a typical prior art installation of a screen cage over a pool area. The same or similar installation can be found of a cage over a lanai. The cage consists of upper, middle and lower horizontal connecting beams  10 ,  12  and  13 . The connecting beams are attached to the upright columns  15  which have the roof trusses  11  attached at their tops. The columns and the horizontal beams are of a hollow construction made of aluminum. Mostly they have either a square or a rectangular cross-section. They are also profiled to have longitudinal grooves therein and at their corners to receive splines therein as will be illustrated in  FIGS. 2-5 . At  14  is shown a deck of a swimming pool which could also be a terrace of a lanai.  
       FIG. 2  shows a perspective view of the construction of a vertical column  1   a . The face  1  of the column faces the inside of the cage. The corners of the front face  1  have grooves  2  therein which are of different shapes depending on the configuration of the splines being used to fasten the connecting strips therein. In  FIG. 2  the groove and the corresponding spline is shown having a triangular cross-section. The entrance to the grooves is somewhat restricted to retain the spline in the groove once it is forced into the groove. The triangular spline  3  has one part of a hook and loop fastening system attached thereto while the screen has the other part of the hook and loop fastening system attached thereto. When both parts of the fastening system are attached to each other, the screen material will be firmly attached to the vertical column. The fastening or attaching of the one part of the hook and loop fastening system will be explained below.  
       FIG. 3  shows a different embodiment of the shape of the spline material. In this embodiment, the spline material is of a rectangular shape. The same reference characters are being used as were shown in  FIG. 1 .  
       FIG. 4  shows still another shape of the spline which in this embodiment is a trapezoidal shape. This Fig. also shows the two parts of the hook and loop fastening system partly pulled away from each other to illustrate the simplicity of the inventive concept. The different cross-sectional shapes of the spline are of no important consequence. It all depends of what is available and what is preferred. Attaching the different parts of the hook and loop fasteners to the spline and to the screen, respectively, can be undertaken in many different ways. The parts could be glued, sewn or vulcanized. The ways of attaching should be weather proof because they are exposed to the elements.  
       FIG. 5  is still another embodiment of the spline having a round cross-section spline. The grooves  18  in each corner of the column face  1   a  are shown as round and the spline  19  is also shown as round. The spline  19  may be hollow to be securely heldin the groove when pressed into the same.  
      It should also be noted that the spline can directly be attached to the edge of the screen whereby the hook and loop fastening system can be eliminated altogether. However, the hook and loop fastening system is preferred.
