Interior, exterior, laminate and painted finish availability varies by series and configuration.
Product specifications and availability can change by series, size and project conditions. Your specialist will confirm the exact configuration in writing.
Casements hinge at the side and swing out at the angle you choose, catching breezes along the wall and opening from top to bottom. They suit spots that are awkward to reach, like over a kitchen sink, because one turn of the handle does the work.
The crank folds flat when you are not using it, so it stays clear of blinds, shades and the sill.
Locking hardware engages at several points along the sash, pulling it in for a tighter, safer seal.

(210) 796-9574Casement windows seal tightly, open fully for ventilation and catch side breezes, which are their biggest advantages. The drawbacks are that the sash swings outward, so it can conflict with walkways, patios or shrubs, and the crank hardware needs occasional care. They also usually cost more than sliders or hung windows of a similar size.
Casement windows are usually more expensive than sliding windows of the same size because they use crank operators, hinges and multi-point locks. The added cost buys a tighter seal and a sash that opens fully. Size, frame material and glass package still drive most of the final price, so comparing both styles with identical glass is the fairest test.
Casements are better for airflow, a tight seal and hard-to-reach spots such as over a kitchen sink, while double-hung windows suit traditional exteriors and openings beside walkways where an outswinging sash would be in the way. Double hungs also accept standard exterior screens. The better choice depends on each room, its layout and how often you open the window.
Casement windows are among the most secure styles because their hook-style locks grip the frame at several points and the sash closes tightly against the frame. Security in any window also depends on lock quality, frame strength and laminated or tempered glass where needed. Keeping locks engaged and installing the window with a solid fit matter more than style alone.
Maintain casement windows by keeping the hinges and crank operator clean, wiping the weatherstripping and checking that the sash closes evenly against the frame. Clean the glass from inside when the sash is fully open, since many designs leave room to reach the exterior pane. If the crank feels stiff, clean the hinge track before forcing it. Our San Antonio team can walk you through care at installation.
