The most important component to your sunroom is the glass. That's why we offer the Highest-Performance Glass Available. 

• Our Millennium Windows are one inch thick insulated glass units with argon filled dead air space for superior insulation, fully tempered for strength and safety, nearly unbreakable.
• Lower maintenance - easier to clean glass, while there is no such thing as self-cleaning glass, E-Z Clean glazing repels dirt and other residue from clinging to the glass. It features a thin layer of silicon dioxide applied to the exterior surface, literally a glass-on-glass coating.
• Cardinal LoE 270 - All climate solar control glass. Features a unique coating that has been specially formulated to reject the sun's heat and damaging rays to provide the ultimate in comfort. The glass is coated with microscopically thin, optically transparent layers of silver sandwiched between layers of anti-reflective metal oxide coatings. This patented coating provides the best clarity and optimum performance.
• SilverCoat E-140, More than a solar control glass. This high technology glass allows you to let the sunshine come in without bringing discomfort to your room while controlling glare. It's multi-layer coating give it the ability to handle each portion of the solar spectrum differently to absorb incoming visible light, making it spectrally selective. Perfect for nighttime star gazing.
• SilverCoat E-366, the latest in Low-E glass technology. The ultimate high-performance glass, delivers the ideal balance of solar control and high visibility. The unprecedented triple layer of silver, gives three layers of year-round thermal protection that blocks more solar gain, reflects heat and lets the light stream in.
• NFRC Approved Windows - Energy performance ratings
• AAMA Certified Windows - For structural performance, air infiltration, water infiltration, acoustics and security.  

All windows should have glass energy performance ratings. If the manufacturer won't furnish you with the actual ratings, then most likely the glass is not the high performance glass that should be used in sunroom applications. There are many types of Low- E coatings. The term "high performance" can be misleading but not untruthful, for example ordinary house windows with a Low-E coating can be called a high performance window, especially when compared with clear glass, single pane house windows. But it would not be a good choice for a comfortable year-round use sunroom.

Several factors should be considered for glass roof rooms. You want the best combination of glass that will give you the greatest efficiency in comparison to visibility. There are some glasses that have good energy ratings but to get the good rating, have a very dark and/or highly reflective tint. These tints are so dark that there is basically no nighttime visibility. This contradicts one of the main reasons for a glass roof room, to be able to stargaze and enjoy the beautiful nighttime views.

There is a difference in glass ratings and window ratings. When using windows ask if the windows are NFRC (National Fenestration Rating Council) certified. Ask to see the certification label (it should be attached to each window). This label will show the certified energy performance ratings. If it is not certified, don't buy it.

AAMA (American Architectural Manufacturers Association) certification grades the structural performance of the window; air infiltration, water infiltration, acoustical and security. This certification is important but has nothing to do with the glass energy performance of the window.

The Vertical Four-Track Panels open up to 75% of the window area for ventilation or can be:

• Removed completely for 100% air flow
• All Four-Track Panels can be completely raised or lowered to create an comfortable outdoor feel
• Tilt-In, Removable Vents make cleaning a breeze
• Sizes to accommodate virtually any size opening
• Outside Mount Frame - Ideal for enclosing an existing porch, deck or patio room
• Inside Mount Frame - Ideal for multi-floor applications such as decks or areas not easily accessible from the outside

For an attractive, spacious and wide-open look, nothing beats the Side-Slider. Available in two and four track frame options, these full-length panels move back and forth at the touch or a finger.

• Inside Mount Frame
• Outside Mount Frame
•  Vent configurations: stacked, staggered, pyramid or condo
• Vent quantities range from 2 - 10 to fill any opening
• Neoprene rollers

PGT Eze-Breeze Garage Door Screens are an affordable way to get more use out of your garage. The rugged screens slide across the garage door opening at the touch of a finger, creating a well-ventilated, screened-in area where you can work or play in comfort. The screens will keep out debris, insects and the neighbor's cat and will glide smoothly out of the way to put the car in. Durable Vinyl can be installed instead of screen to create a weather barrier while letting in the light.

• 2-track or 4 track frame option
• Sill with threshold on both sides
• Vent quantities range from 2 to 10 to fill any opening
• Vent configurations: stacked, staggered, pyramid or condo
• Vents rolled in 1814 charcoal mesh
• Optional vinyl rolled panels keep out wind and rain but let in light
• 8", 12" or 16" Kick plate
• Outside Mount Frame
• Inside Mount Frame
