A hidden insect screen system for tilt-to-clean, double hung windows whereby raising the bottom sash (104) causes resultant opening to fill with insect screen (115a) dispensed from an ordinary self-storing roller mechanism (114) mounted inside bottom rail (109) of said sash and whereby lowering the upper sash (105) causes resultant opening to fill with insect screen (115b) dispensed from an ordinary self-storing roller mechanism (122) mounted inside window head frame (103), all furnished such that vertical edges of the screens are protected from insect passage by contacting weatherstrip-like edge seals (127), and arranged such that insect protection is maintained with minimal interruption when each sash is tilted and its glazing is cleaned, the lower end of the upper screen being attached so as to be quickly repositioned from top to bottom of said upper sash.

A magnetic screen door includes a solid section in a screen to protect the screen from damage as users pass through the screen. In some embodiments, the apparatus includes a first and second panel each comprising a flexible mesh section, an inside lateral edge and an outside lateral edge. A magnetic element may be coupled to the inside lateral edges. One or both panels may include a solid inset. The apparatus also comprises a second panel. In an illustrative use, as an animal presses on the solid inset, the first and second panels separate to allow the animal through. The flexible mesh section is protected from damage since the animal makes contact with the solid inset instead of the more fragile mesh section.

A fenestration system includes one or more of a light modulation controller or ventilation modulation controller. The light modulation controller is in communication with at least one light modulation element of a fenestration assembly having a frame and a panel. The light modulation controller includes a light prescription module configured to provide a specified light prescription for the building interior. A lighting difference module is configured to determine a prescription difference between the specified light prescription and ambient light. A dynamic light module of the light modulation controller operates the at least one light modulation element according to the prescription difference. The ventilation modulation controller is in communication with at least one operator configured to open and close the panel. A ventilation prescription module provides a specified ventilation prescription for the building interior, and a dynamic ventilation module implements panel closing and opening according to the specified ventilation prescription.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly. The sash includes at least one magnet. The sash is slideably engaged with the frame. The at least one screen assembly includes a roller assembly, a control bar, and screen material attached to the roller assembly and the control bar. The roller assembly is substantially hidden from view. The control bar includes a ferromagnetic material. The screen assembly is configured to apply tension to the screen material to wind the screen material around the roller assembly and to permit the screen material to unwind from the roller assembly under a tension applied to move the control bar away from the roller assembly. The control bar automatically engages the at least one magnet of the sash when the sash is in the closed configuration to attach the control bar to the sash.

A fenestration assembly includes a sash, a frame surrounding the sash, and at least one screen assembly mounted in at least one of: the top portion and the bottom portion. The frame includes a top portion, a bottom portion, and two jambs forming first slots extending lengthwise along at least a portion of the jamb. The first slots each include a screen edge retention feature. The screen assembly includes a roller assembly substantially hidden from view, a screen material attached to the roller assembly, and a plurality of raised features. Edges of the screen material extend into the first slots. The raised features are attached to each of the edges of the screen material. The raised features are configured to engage the screen edge retention features and retain each of the edges of the screen material at least partially within the first slot of each of the two jambs.

The present disclosure is directed to a window screen system for use with casement, hopper, awning, utility window designs to prevent dirt, debris, and insects from entering into the interior of the unit. The system can be installed on existing window frames to provide screen protection only when the window is open and a screen is needed. As such, a user can have a clear view out of the glass window without the unsightliness, distortion, or solar blockage that a traditional “always visible” screen causes.

The window assembly of the present invention includes a window frame and window sash rotatable relative to the window frame between a closed position and an open position. In the closed position, the window sash is positioned parallel to the window frame. In the open position, a space is defined between the bottom edges of the window frame and the window sash, and the space defined between the side edges of the window frame and the window sash. A window screen is connected to the two side edges and the bottom edge of the window sash, the two side edges and the bottom edge of the window frame. The window screen is configured to extend in the space. The viewer can have a clear view out of the window assembly without the unsightliness, distortion, or sunlight blockage that is caused by conventional “always visible” window screens.
