Foundation Door-Vent with Insulation

Abstract

InsulVent, the insulated foundation vent, is a crawl-space foundation vent that is designed to open from the exterior as a door. This allows the homeowner to easily open the vent to install insulation during cold weather and remove it during warm weather. The vent is unique because no other foundation vent is designed to open and close from the outside as a door. In addition to a removeable insulation block, the varmint screen is also removeable and replaceable. The door is designed to operate without hinges; however, a hinged version can easily be adapted.

1 . A vinyl frame that fits into a rough opening equal to the size of a cement block. 
   
   
       2 . A vinyl door uniquely designed to open to the exterior without the use of a mechanical hinge, using an angle on the back side of the door configuration that allows it to swing forward and containing grooves for accepting a screen and insulation block. 
   
   
       3 . A replaceable screen. 
   
   
       4 . A small Styrofoam block glued to the top. 
   
   
       5 . A larger Styrofoam block used for insulation. 
     The foundation vent allows the owner the easy access of a door to react to changing climate conditions.
