Sash tilt bolt and checkrail bracket systems for coastal impact resistant fenestrations

An impact-resistant fenestration unit comprising:

• a frame assembly comprising a sill, a head jamb, and two opposed side jambs;
• a bottom sash, the bottom sash comprising a bottom rail, a check rail, and opposed stiles;
• the bottom sash configured to pivot inward away from the frame assembly such that the check rail moves away from the frame assembly;
• the bottom sash configured to move within the frame between a closed position and an open position;
• a first sash tilt bolt assembly comprising a bolt;
• a second sash tilt bolt assembly comprising a bolt;
• the first and second sash tilt bolt assemblies disposed on opposite sides of the check rail;
• a first side bracket defining a cavity to receive a portion of the bolt of the first sash tilt bolt assembly;
• the first side bracket mounted on one of the two opposed side jambs at a height corresponding to a position of the check rail when the bottom sash is in a closed position;
• and
• a second side bracket defining a cavity to receive a portion of the bolt of the second sash tilt bolt assembly;
• the second side bracket mounted on the other of the two opposed side jambs at a height corresponding to the position of the check rail when the bottom sash is in a closed position;
• the two opposed side jambs each comprising a channel extending along a vertical axis of each side jamb, wherein the cavity of the first side bracket forms a portion of the channel of one of the two opposed side jambs, and the cavity of the second side bracket forms a portion of the channel of the other of the two opposed side jambs.
