Abstract: A fenestration assembly is provided. The assembly includes a stationary member, a moveable member coupled to the stationary member, a primary biasing member disposed between the stationary member and the moveable member to provide tension to a film coupled to the moveable member, and a reinforcement member coupled to the stationary member and configured to reinforce the assembly upon tension being provided to the film.

Abstract: A roll of energy-efficient laminate substrate is described. The energy-efficient fenestration assembly includes: (1) a performance film having at least one energy-efficient property; (2) a supporting film mechanically supporting said performance film; and (3) wherein said performance film is laminated and rolled with said supporting film to form said roll of said laminate energy-efficient substrate.

Abstract: A fenestration assembly is described. The fenestration assembly includes: (1) a layer of film; (2) a frame having a first surface and a second surface, which is opposite to the first surface, the first surface substantially surrounding and having secured thereon the film and the frame having a thickness such that when the second side is fitted onto a window or a window frame, the thickness of the frame defines a space between the film and the window; and (3) wherein said film is a low-emittance film having an emissivity equal to or less than 0.35.

Abstract: Energy-efficient fenestration assemblies that effectively secure substrates, such as window films, are described. The fenestration assembly includes: (1) a base frame capable of having secured thereon a substrate; and (2) a tensioner capable of engaging with the base frame such that when the base frame has secured thereon the substrate, the tensioner places the substrate under tension relative to the base frame.
