Exemplary implementations of a thermally-efficient slidable fenestration assembly are glass window systems or glass door systems having one or more sliding glass panels. The fenestration assemblies are adapted to be mounted in an architectural structure such as a building or house. Accessory channels in the fenestration framework may be provided to facilitate nail-fin, retro-fit or screen adaptors as means to attach the assembly to the surrounding architecture. Stiles, tracks and rails of the assembly are specifically configured to reduce heat transfer across the fenestration assembly, while simultaneously maintaining the structural integrity and durability of the overall assembly. Certain stile, track and rail components may comprise materials of relatively low conductivities. Preferred stile configurations include interlock elements arranged to reduce the assembly's vulnerability to tampering from a position outside of the fenestration.

A window frame system for fixing at least a first panel, includes at least a first window frame structure which includes at least a first window frame profile having at least first and second holders, and at least a first thermally insulating element with sixth and seventh holders. The second holder and the sixth and/or the seventh holder of the first thermally insulating element include at least one internal corner with a radius smaller than 0.5 mm. In this way, the dimensions of the window frame profile may be smaller than in the known window frame profiles. This may be advantageous for the total insulation value of the window frame system and the quantity of material required/used for the window frame profiles. Also disclosed is a thermally insulating element, a method, a window frame structure, a flexible profile, a control system and a sun protection system.

Provided herein are thermal break structural members for use in fenestration assembly products. In some embodiments, the thermal break structural member is monolithic with an infill retainer, being designed to bear a structural load while maintaining the overall integrity and thermal performance of the conjoint fenestration unit.

A bead for releasably securing a glazing unit to a frame member, comprising a body having a first end and a second end, and a resiliently deformable member secured to the body and having a first finger extending from the body to a first end, and a second finger extending from the first finger to a second end. The first end of the body and the first end of the first finger are configured to engage with respective first and second ends of a frame member so as to secure the bead to the frame member. The second end of the body is configured to secure a glazing unit against an opposed seal of the frame member. The body comprises a first material having a first stiffness and the deformable member comprises a second material having a second stiffness less than the first stiffness.

A fenestration formed of flattened steel with special thermal break structures therein.

Provided herein are thermal break structural members for use in fenestration assembly products. In some embodiments, the thermal break structural member is monolithic with an infill retainer, being designed to bear a structural load while maintaining the overall integrity and thermal performance of the conjoint fenestration unit.

A frame may include three or more portions having an upper portion disposed adjacent an upper end of an opening and two side portions disposed along either edge of the opening, and in some cases a lower portion when the opening is for a window or some doors. A first frame segment and the second frame segment are adjustable with respect to each other in order to extend around the thickness of the door opening. The segments may have one or more thermal barriers, such as a seal (e.g., u-shaped, v-shaped, or the like seal) located between portions of the segments. The first frame segment may be adjusted with respect to the second frame segment. The adjustment of the segments may be made before or after the one or more thermal barriers are installed.

The present disclosure relates to an insulated frame section. The frame section comprises an elongate interior frame member, an elongate exterior frame member and an elongate insulation element connected to the interior frame member and to the exterior frame member. The insulation element prevents any direct physical contact between the interior and exterior frame members. A refrigerator door system having a door and a door frame constructed from such insulated frame sections is also disclosed.

A building component includes a frame including a first material and cladding connected to the frame. The building component also includes a thermal break defined by the frame intermediate a first side and a second side of the building component and an insulating material within the thermal break. The building component further includes an insulated glass unit including a first glass pane and a second glass pane spaced from the first glass pane. The first glass pane and the second glass pane define a pocket therebetween. The thermal break and the pocket define a continuous thermal break when the building component is in a closed position.
