Casement Windows

Measure the rough opening (width and height) at three points and use the smallest measurement; decide left- or right-hand hinge based on which side you want the crank and how the window will open relative to nearby obstructions; confirm frame depth and sash thickness to match your wall and trim

Common materials are vinyl (low maintenance, good thermal performance), aluminum (slim profiles, durable), and wood or wood-clad (better aesthetics, higher maintenance); choose finishes and coatings rated for weather resistance and consider UV-stable paints or factory-applied finishes to reduce upkeep

Look for multi-point locking or strong single-point locks, corrosion-resistant hardware (stainless or plated), smooth-operating crank mechanisms, and easy-to-replace parts; ensure the operator fits the intended sash weight and usage frequency

Check U-factor (lower is better) and Solar Heat Gain Coefficient (SHGC) appropriate for your climate, look for insulated glass options like double or triple glazing, low-emissivity (Low-E) coatings, and warm-edge spacers to reduce heat transfer and condensation

Yes; casement windows seal tightly when closed because the sash presses against the frame, and they can provide strong ventilation when opened fully, directing airflow into the room depending on wind direction

Retail unit prices commonly range from budget options under $100 to several hundred dollars for higher-performance models; factor additional costs for professional installation, custom sizing, upgraded glazing, trim, and disposal of old windows

Clean frames and glass regularly, lubricate hinges and crank mechanisms annually with a suitable lubricant, inspect and replace worn weatherstripping or seals, and touch up finishes or repaint wood components as needed to prevent moisture damage
