The H Casement Window
Sought-after by architects and building owners for its quality construction, smooth operation, and superior performance, our Projected Casement Window revolutionized the window industry with its innovative hinge design allowing the window to fully rotate for easy cleaning and maintenance.
The Sliding Hinge
The H Window Sliding Hinge
allows a window to revolve a full 180º for easy cleaning and maintenance. The hinge is perfectly balanced at the sash’s center point allowing for smooth and controlled rotation. The robust hinge can support double and triple pane windows up to 15 square feet.
Composite Aluminum and Wood Construction
The H Awning Window, the H Casement Window, and the Fixed Sash window all use the same design shown in this cross-section.
Product Information
Interior wood frames are available in a variety of hardwood, softwood, and bamboo species including Forest Stewardship Council© certified materials. All wood materials are kiln dried and preservative treated to prevent deterioration.
Applied prior to assembly, our three-coat factory finish options include standard and custom paints, stains, and clearcoats.
Wood and bamboo are natural grain materials and will always exhibit individual characteristics and features. The overall look of the product will vary depending on grain, texture, and color of the wood. As such, these images are representative only and not to be considered an exact match of the final product.
Three finish options are available for our extruded aluminum profiles: powder coating, anodized finish, and Kynar® fluropolymer coatings.
Powder Coating, our most common finish, is highly durable in all environments. Select from our stock colors or custom colors.
Anodized finish gives any commercial or residential projects a timeless metallic aesthetic ranging from bright clear to deep black.
Kynar® PVDF coatings are exceptional for their ability to retain color and gloss keeping windows looking vibrant.
Encore Roto-Crank
Streamlined full-flip folding handle will not collapse during operation. Allows the venting angle position to be locked in place.
- ADA compliant optional
Rules of Thumb
Two key considerations for sizing casement windows:
- Frame sizes should not exceed 15 ft²
- The frame cannot be wider than it is tall (always portrait, never landscape).
Egress Requirements:
Minimum frame dimensions for egress casement windows are 28″w x 46″h
The H Casement Window can be paired in a single frame. It is designed to be easily combined into filed mulled arrangements with other H Window door and window products.
Our thoughtful design innovations eliminate mosquitos and maintenance! Extruded aluminum frames with staked corner keys are more robust than typical roll-form aluminum screen frames.
Screens are securely attached to the window frame with ABS latch clips to allow easy removal.
Clear Advantage™ fiberglass screens provide more visibility and ventilation without sacrificing strength or durability. Other fabric options include aluminum mesh, pet resistant, extra strength, small insect, and sun protection.
Design versatility of the H Casement Window is amplified with customizable accessories including divided lites and extension jambs.
