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.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods of maintaining a configuration of a cladding arrangement of a fenestration apparatus.

A profile made of plastic material to fasten a pane to a frame, comprising a first fastening section that can be placed against the pane and a second fastening section that can be anchored to the frame and at least one clamping section projecting away from the fastening sections, the clamping section having a catch to clamp a covering strip, wherein the catch sticks out on one or both sides of the clamping section and wherein one part of the catch is made of a more elastic plastic material than the clamping section with the remaining part of the catch.

The fenestration structures include external frame segments facing the interior and exterior surfaces of a building wall, and an internal frame segment sandwiched between the external frame segments. The external frame segments are made from a relatively hard, dense and/or resilient material, such as hard wood, while the internal frame segment is made from paulownia which is a moisture-resistant, dimensionally stable thermal barrier material. The external frame segments therefore provide durable and attractive exterior and interior surfaces of the fenestration frame, while the internal paulownia segment provides superior resistance to thermal transfer across the frame, while also remaining dimensionally stable across a variety of moisture and temperature levels. Internal paulownia segments may be positioned around the entire periphery of the fenestration frame to create a comprehensive thermal barrier.
