Energy Efficient Glass

Low-E Insulating Glass

Low-E, or low-emissivity, glass has a coating that is applied to reflect heat and keep your home comfortable. It helps to prevent your carpet, furniture, décor and window treatments from fading by blocking most of the sun’s harmful UV rays. Help lower annual heating and cooling costs with Pella’s exclusive glass coatings optimized for your specific geographic region. Most Pella windows come with low-e insulating glass.

Advanced Low-E Insulating Glass

  • Triple-pane: Three panes of glass also available on select product lines for increased energy efficiency. Blocks 86% of the sun’s ultraviolet rays.
  • Best use: Most U.S. climates

Tinted Glass

Tinted glass is popular in very sunny and hot climates and is commonly used in rooms that receive a lot of sun exposure. Like sunglasses, windows and patio doors with tinted glass block some the sun's rays and keep rooms cooler. The glass also helps control glare and provides privacy for your home.

Privacy and Security Glass

Obscure Glass

Commonly used in intimate spaces such as the bathroom and bedroom, obscure and frosted obscure glass create privacy while allowing natural light. A variety of textures are available in both dual-pane and triple-pane glass designs.

Best Use: Areas requiring extra privacy, such as a bathroom or bedroom

Tempered Glass

Tempered glass is available where safety glass is required by code or to increase the strength of the glass as required. This type of glass is incredibly strong, but when broken, it shatters into smaller pieces of glass rather than jagged pieces. This means there is a lower chance of injury, even if the glass is broken. Tempered glass comes standard on Pella patio doors and is less likely to shatter than standard annealed window glass.

Best Use: Places where safety glass is required by code or needed to help increase the strength of the glass

Sound Control Glass

STC (Sound Transmission Class) Sound Glass

Windows and patio doors come with a standard glass thickness. STC sound glass uses mixed glass thicknesses to help dampen sounds. When different glass thicknesses are paired, like 3mm and 5mm glass, they help dampen different sounds at different frequencies – like traffic, airplanes, lawn mowers and more — to keep your home quieter. It is available on dual- and triple-pane products.

Best Use: Areas that experience lots of outside noise

Laminated Glass

Commonly used in locations in need of added security, ultraviolet (UV) protection and noise reduction. A polymer layer sandwiched between two layers of glass that cuts outside noise and harmful UV rays and offers added protection against intruders and forced entry. The interlayer holds the glass together if it's shattered.

Best Use: Homes that need added security, UV protection or noise reduction

Impact-Resistant Glass

Impact-Resistant Glass

Impact-resistant glass provides added protection for your home from intruders and storms such as hurricanes. It is designed to help maintain the structural integrity of your home and features a strong polymer interlayer sandwiched between panes of glass. This interlayer holds the glass together if impacted. Impact-resistant glass also provides exceptional noise reduction.

Best Use: Places that need extra security or strong storm protection

Additional Glass

Spandrel Glass

Commonly used between sections of a multi-story building including the area between floors, columns, ceilings, and other small or large spaces, spandrel glass creates the visual appearance of a glass wall. Spandrel is created using fired-on frit methods. This process includes a ceramic frit that is fused to the glass using high heat fusing methods and creates a glass that will not fade over time. In addition, spandrel glass is up to five times stronger than annealed glass.

Best Use: Common between sections of a home or building between floors, columns, ceiling or other spaces

High Altitude Glass

For homes and buildings located at a high altitude, like in the Rocky Mountains, the air-filled insulating glass assembly is typically vented to prevent over pressurization of the system. If argon gas fill is used, the insulating glass is filled to a pressure level tailored for higher elevations.

Best Use: High altitude homes
