Window film in Salt Lake City.

Historic glass in the Avenues and Capitol Hill

A large share of our Salt Lake calls come from the Avenues, Capitol Hill and Federal Heights, where the original wood-sash single-pane windows are part of what makes the house worth owning and replacing them is either unaffordable or not permitted. Film is the only upgrade that improves those windows without touching them.

On single pane we lean toward a Low-E film, because those windows lose heat in January as badly as they gain it in July. A Low-E layer reflects your radiant heat back into the room, which is the difference between a north-facing Avenues bedroom being usable in winter and not. On the summer side, the same film cuts the afternoon load coming through west glass.

Historic districts also mean design review. We stay away from mirrored exteriors on contributing structures and use neutral films that read as ordinary glass from the sidewalk.

Downtown, Sugar House and the 9th & 9th corridor

Downtown offices and Sugar House mixed-use buildings are the opposite problem: enormous glass area, modern insulated units, and an HVAC system that still cannot hold a south-facing floor at temperature by two in the afternoon. Here the win is straight solar rejection across every exposed elevation, scheduled after hours so nobody loses a workday.

Ground-floor retail along 9th & 9th and 15th & 15th usually wants two things at once — merchandise that stops fading in the window and glass that does not open on the first strike. Sleek Shield+ handles both in a single install.

Inversion, and why glare is worse than people expect

Winter inversion in the valley scatters light rather than dimming it, so low-angle January sun through a haze layer produces a diffuse glare that blinds a monitor or a TV more effectively than a clear summer afternoon. Salt Lake homeowners routinely tell us the worst glare month is not July.

A moderate-VLT solar film knocks that down without darkening the room, which matters on the short days.
