Claims

VENTILATED ANTI INSECT SCREEN (V.A.I.S.)

V.A.I.S. can be fitted as a sealed unit, or as a unit that opens (in the event of a fire), to fit any size of window, door, ceiling and conservatory. V.A.I.S. can be purchased in laminated glass, plate glass or perspex (in a variety of colours), set in either an aluminium, wood or uPVC frames, with holes strategical placed, that houses the anti insect mesh holder. V.A.I.S. offers a high degree of security to the building, when fitted with the laminated glass unit. V.A.I.S. does not restrict the flow of fresh air into the building. V.A.I.S. allows easy exit from the building in the event of a fire. V.A.I.S. provides clear visibility, and is easy to clean. V.A.I.S. will not shatter or collapse (where fitted with the laminated glass unit) thus reducing the possibility of injury. V.A.I.S. is easy to install and requires the inumium of maintenance. V.A.I.S. reduces heat gain internally (where fitted with the bronze colour laminated glass unit). V.A.I.S. conforms to British Standard BS 6206 Class A (laminated glass unit). V.A.I.S. will be in demand by builders and construction companies in Africa, Middle East, Near & Far East, U.S.A., Canada, Australia, South Africa, South America, West Indies, Spain, Portugal and parts of Russia, in the construction of new buildings. V.A.I.S. would also be installed in existing buildings. V.A.I.S. can be installed in a building of most types of construction. V.A.I.S. has been invented to combat the spread of malaria indoors. V.A.I.S. has undergone stringent medical tests that proves by installing V.A.I.S., the reduction in mosquito and other insect bites therefore significantly reduces insect carrying diseases.
