Press fit storm window system

A system for mounting a secondary, rigid panel within a window frame of an existing window in a building, the system comprising:

• a rigid panel having an edge;
• an elongated, deformable bulb having:
• a resilient portion,
• a base section,
• an extension extending from the base section, and
• a crosspiece coupled to a distal end of the extension, the crosspiece including a pair of shoulders at opposite ends of the crosspiece, each shoulder protruding laterally beyond the extension extending from the base section;
• and
• an elongated carrier configured to receive at least a portion of the edge of the panel within a panel gap of the carrier, the carrier having a receiving slot opposite the panel gap, the receiving slot having a neck laterally narrower than an interior cavity of the receiving slot, the receiving slot configured to securely receive the crosspiece of the bulb and to confine the shoulders of the crosspiece, the carrier further including yieldable nubs within the panel gap, the nubs structured to support and retain the panel within the carrier.

A system for mounting a secondary, rigid panel and flexible sheet within a window frame of an existing window in a building, the system comprising:

• a flexible sheet having an edge;
• an elongated, deformable bulb having:
• a resilient portion,
• a base section,
• an extension extending from the base section, and
• a crosspiece coupled to a distal end of the extension, the crosspiece including a pair of shoulders at opposite ends of the crosspiece, each shoulder protruding laterally beyond the extension extending from the base section;
• and
• an elongated carrier configured to receive at least a portion of and edge of the panel within a panel gap of the carrier, the carrier having:
• a receiving slot opposite the panel gap, the receiving slot having a neck laterally narrower than an interior cavity of the receiving slot, the receiving slot configured to securely receive the crosspiece of the bulb and to confine the shoulders of the crosspiece, and
• a first protrusion and a second protrusion extending laterally away from a first side of the elongated carrier, the first protrusion and the second protrusion being configured to receive between them the edge of the flexible sheet and an elongated spline, the flexible sheet being pinched between the spline, the first protrusion, and the second protrusion.
