Vista VS 61 SR CDF - Spectrally Selective

About VS 61 SR CDF - Spectrally Selective

VS 61 SR CDF is the lightest Vista SpectraSelect option in this Philadelphia catalog, built for projects where visible change to the glass is the first concern. Its 61% visible light transmission keeps rooms bright, while spectrally selective technology targets infrared heat more than daylight. Because the construction is non-metallized, it also avoids the RF and cellular interference questions that can come with metal-based solar films.

That makes VS 61 especially useful on Society Hill brownstones, historic district facades, condominium associations, and storefronts where review boards or ownership rules leave almost no tolerance for a noticeable tint. It is the film to consider when the building needs relief from afternoon heat but the windows still need to read as original, clear architectural glass from the street. That is a common concern on divided-lite windows, older sash, and prominent front elevations where even a small visual shift can create objections before performance is considered.

In practical terms, 61% VLT means more than half of visible daylight still passes through the window, while the film rejects up to 49% of solar heat and blocks over 99% of UV. The low-reflectance appearance helps preserve exterior character, and the infrared-focused performance supports comfort without relying on a mirrored surface. Compatibility still depends on glass type, orientation, and insulated-glass details.

Choose VS 61 when the project values daylight and appearance above maximum glare control. VS 60 is a close alternative when a slightly firmer specification is acceptable, while V 58, V 45, and the 33% films step progressively into more visible tint and stronger light management. VS 61 is the preservation-sensitive starting point of the lineup.
