A window reveal kit can include a window, a first connector, and at least one reveal trim. The window has an outer side, an inner side, and a frame portion about a perimeter of the window. The first connector can be formed on the frame portion, on the inner side of the window. The at least one reveal trim can have a second connector that is configured to engage the first connector so that the reveal trim extends from the first connector.

The support and insulation element for supporting and insulating a window frame has a support part and an insulating part. The support part has a first leg comprising a first side surface, a second leg, which projects from the first leg, and a third leg, which projects from the first leg a certain distance away from the second leg. The support part is made of load-bearing material. The insulating part is arranged at least on the side of the first leg of the support part opposite the first side surface and is made of compacted mineral wool or a rigid foam. The insulating part comprises two slots, into which the second leg and the third leg of the support part are inserted. The insulating part surrounds three sides of both the second leg and the third leg of the support part.

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.

The building section comprises a wall and a peripheral window case, into which a window frame is inserted. The window case comprises several support sections arranged a certain distance apart and standing laterally out from the wall, each support section comprising a support part and an insulating part. The first leg of the support part is screwed to the wall, whereas the window frame is screwed to the second leg of the support part. The insulating part surrounds three sides of the second leg of the support part. In the areas between the support sections, the window case comprises insulating sections. The insulating parts of the support sections and the insulating sections bring about a substantially continuous insulation of the window frame around the window case.

A method of manufacturing a door stile includes bonding a composite edge band to a first side of a core and profiling the composite edge band. The edge band includes a hollow that is defined through the composite edge band to flex when compressed into the first side of the core. Profiling the composite edge band includes removing portions of the composite edge band that define the hollows.
