Tinted Insulating Glass
When to Choose: Rooms that get direct sun
Features: Blocks the sun's rays, so it controls glare and keeps rooms that get direct sun cooler. The tint also helps block the view into your home.

Laminated Insulating Glass
When to Choose: Added safety and noise control
Features: Features a polymer interlayer that holds the glass together if it's shattered - for added protection from intruders, as well as reducing outside noise.

Understanding Center-of-Glass Values
Center-of-glass (COG) value - glass alone, no frame - is an easy way to compare the energy performance for each glass type shown below. (Note that these numbers differ from the products' NFRC labels which show "whole product" - glass and frame - values.)
U-Factor
The U-Factor represents the rate of heat flowing out of the window or door in an hour's time. The lower the number, the better the glass insulates.
SHGC
Solar Heat Gain Coefficient rating tells how effective the product is at blocking the radiant heat. The lower the number the less heat the glass allows into your home.
1 Glass options can be upgraded to offer the benefits of our InsulShield energy performers. Glass options may vary per product. See specific product information for availability.
2 Optional high-altitude Low-E insulating glass does not contain argon in most products. Please see your local Pella sales representative for more information.
3 Pella® Designer Series® windows and patio doors with Advanced Low-E triple-pane glass have superior NFRC U-Factors and SHGC ratings among top national wood brands.
4 When compared to top natonal wood brands with similar glazing, Pella's triple-pane glass significantly reduces sound transmission.
5 Pella's HurricaneShield impact-resistant insulating glass is made up of a sheet of tempered glass combined with a sheet of laminated glass. For best performance, the laminated glass may be the interior or exterior pane of insulating glass, depending on the product. It can withstand an impact equivalent to that of a two-by-four traveling at 50 feet per second.
