<p>A secondary interior window insert is described which comprises a frame, at least two panes, one or two flexible integral glass sealing lips, a spacer insert located between the panes, a sealing plate and means to tie up panes, frame, sealing plate and glass sealing lips. The device may further comprise integral friction fit seals, a jamb cover. The device is easily mountable and easily removable. All parts are recycable. This interior insert not only reduces the heat loss of existing windows several times but also covers the window jamb that often consists of cold conducting jambs thus eliminating cold drafts from the window. The formation of condensation or ice in cold climate zones on the panes is eliminated and damage from melting ice is prevented. This window insert will reduce the heating cost and help to curb the greenhouse effect. The insert window contains several sheets of glass or plastic that create additional dead air spaces. Additional heat retention is created by adding a low-e coating to the glass and a low-e foil to the plastic window pane. The insert window frame contains a groove to retain a cover strip that extends from the frame to insulate the cold window jamb. It also represents an improvement with respects to ease of assembly by having the seals extruded as integral part of the frame.</p> |
