An astragal for a fenestration system includes at least first and second slots running along opposite sides of the astragal, each slot is configured to receive a stile of a panel of the fenestration system. The slots may be in different planes or in a common plane, and may be different depths or the same depth. In some embodiments, additional slots are provided in the astragal, on one or both sides of the astragal, and the astragal may be used in various placements and configurations within multi-panel door or window systems. A snap clip may be included within one or more of the slots to engage a stile when received in the slot and secure the panel to the astragal. Covers may fill slots that are not utilized in a particular panel configuration.

The present utility model relates to a middle strip of a door frame, which can effectively solve the problem of insufficient strength existed in the middle strip of the door frame of the prior art. A middle strip of a door frame comprises a middle strip body, wherein a positioning hole is disposed in the middle strip main body along the length direction of the middle strip body, and the positioning hole is provided with a support frame in order to enhance the strength of the middle strip body, and the support frame is arranged along the inner wall of the positioning hole. The present utility model has the following advantages: a positioning hole is disposed in the middle strip body along the length direction, and the positioning hole is provided with a support frame, therefore, he strength of the whole middle strip body is effectively improved via the support frame without changing the size and the shape of the original middle strip body, so that the middle strip body will not deform easily during the using process and has a sufficient strength.

A frame assembly for a fenestration assembly includes a frame having a first side, a second side, a third side, and a fourth side. A groove is disposed continuously along the first side, the second side, the third side and the fourth side. A one piece reinforcement is disposed within the groove of the frame and a trim assembly positioned over the one piece reinforcement and the frame.

A construction profile is made of polymeric material and defines an inner cavity. The construction profile has an outer surface comprising unexposed side portions and exposed side portions. A stiffening profile is provided external of the construction profile and at an unexposed side portion thereof. The stiffening profile has a polymer material and a reenforcement material. The stiffening profile has a tensile (flexural) modulus in its length (L) direction of at least 5 Gpa according to EN2561 and the polymer material has a lambda value of maximum 2 W/mK.

A reinforcement apparatus mounts onto one or more extruded plastic window frame members of a window frame. The apparatus includes a reinforcement frame member comprising an extruded profile having a hollow interior and being formed of a fibre composite material. The composite reinforcement frame member is shaped to mate externally alongside the hollow profile of the respective window frame members to both extend the jamb and stiffen the plastic window frame member. In this manner, lower cost plastic window frames can be reinforced subsequent to the assembly of a window frame in a cost-effective manner.

A customizable storm protection system for protection and aesthetics comprises a first jamb, a second jamb, a header, and a sill, each with a glazing recess, and each with a receptacle for inserting a screw boss that runs a length of each of the first jamb, the second jamb, the header, and the sill, wherein joined define a frame for the opening in a building. A customizable storm protection system may further comprise glazing received by the glazing recess of each of the first jamb, the second jamb, the header, and the sill. A customizable storm protection system may further comprise a storm track configured to the frame to, wherein the storm track identifies fastener locations for the screw boss within the frame, and wherein the storm track comprises a cap, a stanchion, and an attachment layer for attachment to the frame. The system enables different openings in a building to be individually customized for different types of storm protection while maintaining a uniform exterior appearance.
