Strata EX 35 Semi-Mirrored Film — For External Use

Strata EX 35 is a semi-mirrored sun protection film for the outside of the glass. It gives daytime privacy, cuts the heat and the glare, and keeps the window looking like a window rather than a dark panel.

Privacy with One-Way Visibility

The semi-mirrored surface of Strata EX 35 gives one-way visibility: from outside the glass reads as a mirror while it is brighter outdoors than in, and from inside you keep the view out. At night this reverses — with the light on indoors and darkness outside, the room becomes visible from the street. That is how every mirror film behaves, and it is worth knowing before you order. Explore further details in the section dedicated to one-way reflective films.

Custom Cut to Fit Your Requirements — Dimensions in Inches

Every window is its own size, so we cut Strata EX 35 to your measurements.

Provide your window dimensions in inches, such as 26 18/32" x 38 14/32", and we will supply you with precisely cut film pieces, ready for easy installation — no scraps to pay for.

Note: we also offer an alternative version of this film for interior installation. Please check out the Strata 35 product page.

Sunlight and Heat Reflection

Strata EX 35 rejects 71% of the total solar energy — TSER 71% — and transmits 32% of the visible light (VLT 32%). Being an exterior film, it stops that energy before the glass, which is what makes it the right choice for double glazing: an interior film lets the pane absorb the heat first. For more information, refer to the section on exterior heat solar films.

The Strata EX 35 for smaller to medium-sized windows

Strata EX 35 suits smaller and medium windows, and anyone who does not want the room darkened. At VLT 32% it takes less light than the darker models, so there is enough tint for daytime privacy and glare control while the room stays lit.

For more on light control, you can explore the mirror tint film section on our website.

For large glass areas a deeper tint is the usual choice. Strata EX 20 transmits 22% of the light and rejects 83% of the solar energy. Bronze EX 20 is the same level — VLT 21%, TSER 83% — with a bronze tone instead of silver.

Self-Adhesive Installation

The film is self-adhesive and goes on with a mounting solution — the adhesive layer is already on it. The install is wet: the solution goes on the glass, the film onto the solution, and the water is worked out with a squeegee. It is a job a first-timer can do, and the same one professional installers do.
