Style & Design


Kolbe offers glazing options to provide optimum energy efficiency for the geographic region in which you live. Low-E is a "smart" coating that reduces energy transfer through the insulating glass unit. The result is reduced heating and cooling costs throughout the year. Low-E coatings also reduce the potential for condensation, as well as provide protection against fading of furniture, fabrics and carpeting.

Kolbe offers the following Low-E glass options, as well as many specialized options. For specific ratings, please search our Energy Performance database. Plus, standard glass used in our products contains 25-30% recycled content.

Solar Low-E
Suitable for most climates and meets most energy zone requirements. Solar Low-E glass is designed to reflect room-side heat back into the room during winter months. In summer, visible sunlight is allowed in while blocking most of the sun’s infrared heat energy. Kolbe's standard.

Solar Control Low-E
Offers an ideal balance of solar control and high visibility by blocking 95% of UV rays while maintaining the interior temperature.

Solar Advanced Control Low-E
A tinted glass recommended for warm climates that achieves solar control over a wide range of the spectrum, while also helping to reduce glare.

Solar Increased Control Low-E
Provides a four-layer silver coating with 52% visible light transmission while offering 99% UV protection. This glass is generally used in warm climates and is formulated to manage solar heat gain while maintaining clearer views.

Solar Gain Low-E
When the weather turns frigid, Solar Gain Low-E glass is the perfect cold remedy. It keeps homes warmer and more comfortable by blocking heat loss to the outside and letting the sun's heat stream in to increase solar heat gain.

ThermaPlus Low-E
An additional Low-E coating which helps to meet the strictest energy requirements by providing protection against heat loss and UV damage. Available with dual pane versions of Solar Low-E, Solar Control Low-E, Solar Increased Control Low-E, or Solar Advanced Control Low-E glass.

Triple Pane
Provides a greater energy performing window that keeps indoor air warm and comfortable, prevents heat loss and lowers your heating bills. It is constructed with three panes of glass, thermal spacer bars and is available in Solar Low-E, Solar Gain Low-E, Solar Control Low-E and Solar Advanced Control Low-E glass.


Standard in Kolbe doors to address safety concerns. Also available in window units to meet specific building codes.

Benefits include safety, security, sound control and provides the ultimate in UV blockage.

Impact Glazing
utilized to withstand harsh environmental conditions, especially in coastal regions. Combined with an impact rated product, this glazing offers the highest level of security.

Tinted, Colored or Patterned
Provides shading, privacy or visual interest.

Harnesses the sun's UV rays to breakdown greenhouse gases, other pollutants and loosens dirt so water can rinse it away, leaving windows cleaner, longer. A special sputter-coating process makes the glass ultra smooth, so the water "sheets off" more readily than it would on uncoated glass, allowing you to spend less time cleaning.

Preserve® Film
A protective film that protects the glass surfaces from scratches during transit and construction, as well as reducing the time involved in job site clean-up.

Smart Glass
Kolbe offers a selection of windows and doors with smart glass that can switch from transparent to obscure on demand – for various levels of privacy when and where you need it. Easily integrated with smart home systems, this switchable glass provides modern versatility and dynamic shading – whether ‘on’, ‘off ’ or anywhere in between.

Bird-Safe Glass
Has a pattern or design on the exterior surface of the glass so birds can see the solid barrier. The patterns can range in visibility to humans so the view is not obstructed. Contact your local dealer to request samples and select the best solution for your project.

Turtle Glass
Achieves turtle code lighting ordinance enforcement while meeting all other NFRC thermal performance standards.

Not all glass is available on all product lines. Please contact your Kolbe dealer for product specifics.
