100% VIRGIN VINYL Will never yellow, flake or crack with excellent insulating properties that stand up against extreme weather conditions year after year and is virtually maintenance free
AIR-LOKS Added sash limiters to prevent sashes from raising or lowering more than 3”
ARGON GAS Argon gas reduces temperature transfer to help lower energy cost and keep your home comfortable all year long. Odorless, colorless, on-toxic inert gas between the panes of glass to reduce temperature transfer
BEVELED EXTERIOR An angled extension from the frame that adds an aesthetically-pleasing dimension to the exterior of the window
HIGH DENSITY NYLON ROLLERS FOR 2-LITE AND 3-LITE Smooth gliding rollers for a lifetime of carefree operation
CONDUCTION Heat transfer from one material to another by direct contact
CONTOURED LIFT RAILS Molded into the sash for a long-lasting performance
CONVECTION Heat transfer by currents that flow from a warm surface to a colder one
DUAL CAM LOCKS 180- degree self-contained lock for added security. Two locks on sashes over 28”, single lock under 28”
DENNY CLIP PIVOT SYSTEM Locks securely into the base to maintain perfect alignment of the sash for smooth operation
DUAL FIN WEATHER-STRIPPING Around the sash perimeter and triple weather stripping at the head and sill provide superior protection from outside elements
FLORIDA E Glass with a transparent metallic oxide coating applied onto or into a glass surface “the coating allows short wave energy to pass through, but reflects long wave infrared energy, which improves the U-value”
FLUSH-MOUNT TILT LATCHES Mechanism that unlocks the sash and allows it to tilt in from the main frame. Flush mount for superior look *Larger windows may require a top-mounted latch
FUSION WELDED FRAMES AND SASHES 45- degree welded corners to effectively stop air and water infiltration while assuring a true and square frame to reduce seal failure
GEOMETRIC Specifically designed windows classified as either straight line geometrics such as rectangles, triangles, trapezoid, octagons, pentagons, etc., or radius geometrics, which include half-rounds, quarter rounds, circles, ellipse, eyebrows, etc
INTERCEPT SPACER SYSTEM Unique U-shaped design keeps glass warmer for increased efficiency and comfort, while flexing and contracting to reduce seal failure
KEEPSAKE MAXIMUM GLASS .06 AND .09 An effective barrier against forced entry and extremely difficult to penetrate – deterring would-be intruders. Hurricane approved for flying debris that may break the exterior pane of glass while the interior laminated pane will stay intact to protect the inside of the home
LAP-LOK MEETING RAIL Overlaps and interlocks the sash to create a tight seal that virtually eliminates air and water infiltration
LIFT RAIL A hand-hold for raising and lowering the sash
MULTI-CHAMBERED FRAME AND PANEL PROFILES Increase strength and thermal performance
OBSCURE GLASS Glass that has been made translucent instead of transparent
R-VALUE Resistance material to heat flow. The higher the R-VALUE, the greater the resistance
STAINLESS STEEL CONSTANT FORCE BALANCE SYSTEN WITH COIL SPRING BALANCER Allows the sash to raise and lower smoothly, ensuring a lifetime of trouble-free operation
STC 35 RATING Sound-dampening plastic interlayer (.06 / .09) provides 50% sound reduction over standard glass and reduces unwanted outside noise

TEMPERED GLASS Safety glass that disintegrates into small, rounded particles instead of large, shape fragments

TRIPLE-STEP SLOPEED SILL Exclusive triple-stepped sill forces water away from the window more quickly than flat, conventional sills that help prevent your home from water infiltration, even in heavy rain

TURTLE CODE GLASS Grey-tinted glass used on windows facing the beachfront to dull the impact of light so that hatchlings turn toward the moon

U-VALUE Amount of heat transferred through a material. The lower U-Value 0the slower the transfer and the better insulating quality
