Glare Control Glass

The Best Glare Control Glass Just Got Better

Meet the next evolution of solar performance glass. Lodz-340+® replaces the previous Lodz-340 with improved aesthetics, better visual clarity, and built-in Neat+™ coating — all while delivering the same unbeatable solar heat and glare protection for the hottest climates.

Sun Strong. Eye Easy.

Blinding glare has met its match. Lodz-340+ tamps down intense sunlight without darkening the room. Engineered for high-sun regions, it improves indoor comfort with controlled brightness — reducing eye strain, TV reflection, and uncomfortable hotspots.

Clear Glass

Transmits 80% of solar energy. No glare control, no protection. Blinds required.

Gray Tinted
Glass

Cuts solar energy and visible light by 40%, but poor solar heat control. Glass temperatures can exceed 100°F (as monolithic laminated) or 96°F (as IG unit).

Glare Control
Glass

Rejects most solar heat, controls glare. Rooms stay cool, comfy and attractive.

Glare Control That Looks as Good as It Works.

The new Lodz-340+ introduces a refined neutral appearance. This improved look blends seamlessly with high-end frames, natural surroundings, and contemporary architecture.

Lodz-340+
Regular Low-E Glass
Engineered for Maximum Performance.

340+ uses advanced spectral filtering to reject infrared (NIR) and ultraviolet (UV) energy while letting in more visible light than traditional tinted glass. You get better daylighting without the heat buildup or increased fading risk.

Ultraviolet (UV)

Near Infrared (NIR)
Invisible; comprises about 3% of total solar energy. Primarily responsible for the fading and deterioration of fabrics, paints, furniture, and other materials.
Visible to the human eye; makes up about 45% of total solar energy. This is the portion of sunlight that illuminates and allows us to see.
Invisible; accounts for approximately 52% of total solar energy. This portion is mainly associated with heat, contributing to solar heat gain through windows and other surfaces.

Lodz-340+: Precision Performance

98%

Blocks over 98% of the harmful UV radiation.

Absorbs 48% of the visible light, which gives the coating glare control and its soft muted gray color

99%

Reflects nearly all the heat-producing infrared rays.

Extreme Solar
Control. No Trade-Offs.

Lodz-340+ blocks the heat where it matters most: under direct, intense sun, thanks to its 0.18 SHGC rating. And unlike heavily tinted glass, it keeps 39% of visible light flowing in, so your spaces stay bright and inviting.

It’s built for high-solar environments where comfort, clarity, and lower energy bills all matter. Tints sacrifice daylight to perform; 340+ delivers both.

Clean Comes Standard

Every 340+ Pane Ships with Neat+™ coating

With Neat+ built-in, 340+ stays cleaner longer. Dust, dirt, and organic debris rinse away more easily. That's less maintenance, better views, and long-term performance without added cost.

Next-Gen Glass for Next-Level Conditions

Lodz-340+ is a big upgrade compared to last-generation coating technologies.

The Coastal Upgrade

Solar + Storm Protection in One

Lodz-340+ pairs perfectly with Sea-Storm laminated glass to deliver advanced solar performance and hurricane-grade impact resistance in one unit. Whether used in a monolithic laminated configuration for code zones without U-factor requirements, or in a dual-pane IG unit with one or more laminated lites, 340+ brings unmatched solar control to the toughest environments. It’s a smart, resilient solution for hot, storm-prone regions like Florida and the Gulf Coast.

Year-Round Comfort

Winter or Summer, this Glass Performs.

Lodz-340+ isn’t just for blazing heat. It retains warmth in the winter while blocking summer sun, creating a balanced interior year-round. Ideal for regions with broad seasonal swings and demanding performance specs.

Year-round thermal comfort is a result of warm glass temperatures in the winter, cool glass temperatures in the summer, and the blockage of oppressive solar heat gains. Note in the chart below that the solar blockage for single pane tinted glass is marginal, and the extreme temperature fluctuations can lead to serious year-round comfort problems.

Double glazing improves the winter comfort, especially when a low emittance Lodz coating is used. A double-pane window with a conventional tinted glass and low-e on the #3 surface (air space side of indoor pane) improves the solar blockage but leaves the building occupants exposed to hot glass temperatures in the summer. Lodz-340+ is placed on the #2 surface (air-space side of outdoor pane) and provides the best comfort through all the seasons.
