The superior gloss of the 4000 Window Series profiles is achieved through the combination of the following factors: the type of raw material used, the extrusion method and special tools, and greater compaction of the components. Glossy profiles are less porous, making your windows easier to clean.
The extruded aluminum bar with overlap gives the screen greater rigidity, increasing durability and protection from insects.
TRIPLE WEATHERSTRIPPING SYSTEM
All weatherstripping is located on the sash for maximum tightness. A coextruded blade further enhances the look of the sash.
STAINLESS STEEL HARDWARE AND ENCORE OPERATING HARDWARE WITH INTEGRATED RETRACTABLE HANDLE
Operators, hinges, multi-point rods, sash snubbers and screws: we only use stainless steel hardware. Say goodbye to corrosion problems! Also eliminated are the inconveniences caused by a handle that obstructs the use of blinds.
