<p>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.</p> |
