Compare Boyd Aluminum casement window options
The table below compares project-out and project-in aluminum casement windows, thermal-strut casement systems, historic-replica casement options, coastal casement/projection windows, blast- and impact-related configurations, and SV100 zero sightline vents. Several project-in and project-out configurations are published as casement projection windows, so that term appears where it matches Boyd Aluminum product documentation. If drawings use in-swing or out-swing language, Boyd Aluminum can help align the operation terminology with the selected series.

Product ratings, blast requirements, impact requirements, glazing thickness, installation method, opening size limits, and approval paths are configuration-specific. Confirm the selected series against current Boyd product documentation and project requirements before bidding, specifying, or submitting.

How to Choose a Boyd Casement Window System

The right Boyd Aluminum casement window depends on operation type, appearance goals, thermal requirements, historic review, glazing requirements, performance documentation, opening conditions, and surrounding wall or framing conditions. For project-in and project-out configurations, project teams may also see casement projection window terminology in drawings, schedules, or product references.

• Use project-out configurations when the opening and project requirements call for outward-operating aluminum casement windows. If drawings use out-swing language, Boyd Aluminum can help match that terminology to the selected project-out casement documentation.

• Use project-in configurations when the opening and project requirements call for inward-operating aluminum casement windows or interior-side access considerations. If drawings use in-swing language, Boyd Aluminum can help match that terminology to the selected project-in casement documentation.

• Use 3250XTC or 3250XTC-G options when thermal-strut performance, a 3.25" frame depth, and 1.75" maximum glazing are important starting points.

• Use 3250XTC-G options when the project needs a historic-replica casement appearance with thermal-strut performance.

• Use 6400 or 4400 options when historic, coastal, or high-performance casement requirements are driving the review, subject to current product documentation.

• Use 2400 options when harsh-weather, blast-related, or impact-related requirements may drive the product path. Confirm the exact project-in or project-out configuration and supporting documentation before specifying or bidding.

• Use SV100 Zero Sightline Vents when the project needs a discreet operable vent path in a storefront or curtain wall condition, subject to compatibility review.

Common Casement Window Coordination Issues

Aluminum casement window selection often depends on details that are not obvious from the product name alone. Review these items before finalizing the Boyd series, bid scope, or submittal path.

• Operation and access: Confirm project-in, project-out, in-swing, or out-swing terminology shown in the drawings, along with hardware expectations, screen requirements, cleaning access, and surrounding clearance conditions.

• Glazing and frame depth: Match glass thickness, glazing makeup, frame depth, and thermal requirements to the exact product series.

• Performance documentation: AAMA/NAFS ratings, impact requirements, blast requirements, wind-load criteria, water performance, and energy requirements should be tied to the selected configuration and supporting documents.

• Historic appearance: For historic-replica work, coordinate muntin type, profile appearance, finish, existing opening conditions, and any authority-review requirements.

• Surrounding conditions: Panning, receptor systems, caulk backers, mullions, snap trim, anchors, substrates, and field dimensions can affect the final product path.

• Storefront or curtain wall vent conditions: For SV100 vents, confirm the selected framing system, glazing condition, project-out vent configuration, and compatibility requirements.

Commercial Casement Window Questions

What is a commercial aluminum casement window?

A commercial aluminum casement window is an operable aluminum window hinged along one side so the sash swings open like a door. Unlike sliding windows, casement windows open by using operating hardware rather than sliding vertically or horizontally. Because the sash presses against the frame when closed, casement windows are often reviewed for tight weather sealing, unobstructed glass area, and ventilation in commercial, institutional, renovation, and specialty building projects.

Boyd Aluminum offers aluminum casement window options in project-out and project-in configurations, with narrow sightlines, thermal-strut options, historic-replica options, coastal casement/projection paths, and zero sightline vent options depending on the selected series and project documentation.

What is the difference between casement, awning, hopper, and projected windows?

Casement, awning, hopper, and projected windows describe how the sash is hinged and which direction it opens. A casement window is hinged at the side and swings inward or outward like a door. An awning window is hinged at the top and opens outward at the bottom. A hopper window is hinged at the bottom and opens inward at the top. A projected window operates on hinges or arms that allow the sash to project outward or inward.

Boyd Aluminum casement and casement/projection series are offered in project-out and project-in configurations. Confirm the exact operation, hardware, clearance, and selected series against the current product documentation and project drawings.

What is the difference between project-out and project-in windows?

Project-out windows open toward the exterior, while project-in windows open toward the interior. Project-out is commonly reviewed when exterior-opening operation fits the wall condition and interior clearance should remain open. Project-in is commonly reviewed when exterior projection is restricted or when interior-side access, cleaning, or operation is preferred.

Project-out and project-in terminology may also appear as out-swing and in-swing in drawings or schedules. Boyd Aluminum can help project teams align that operation language with the correct casement or casement/projection series.

Are aluminum casement windows energy efficient?

Casement windows tend to seal tightly because the sash compresses against the frame gaskets when it is cranked or closed shut, which helps limit air infiltration compared with sliding window operation. Total energy performance still depends on the frame, thermal break, glazing, weatherstripping, and installation details.

For projects with thermal targets, Boyd Aluminum offers thermal-strut casement series such as 3250XTC and 3250XTC-G. Confirm current ratings, glazing options, and configuration-specific documentation for the selected series before specifying, bidding, or submitting.
