Series B460XT Front-Set Thermal Aluminum Storefront System

Boyd's Series B460XT is the industry's first dual pour-and-debridge thermal barrier front-set commercial aluminum storefront glazing system, delivering unmatched thermal performance. The ASTM-tested system has a 2" sightline, 4.5" frame depth, and 1" maximum glazing capacity, while its front-set glass plane creates a curtain-wall aesthetic for a seamless, consistent exterior appearance.

Series B460XT is ideal for high-performance storefronts, new construction, storefront replacement, adaptive reuse, and cost-effective historic renovations. It is compatible with Boyd historic grids and offers outside-glazed, inside-glazed, and structural silicone glazed (SSG) options; screw-spline or shear-block construction; Series SV100 zero-sightline vent compatibility; heavy-duty, corner, and variable mullions; anodized and painted finishes; and seamless integration with Boyd commercial aluminum entrance systems.

Boyd maintains a full inventory of storefront-system accessories, allowing the team to prepare, package, and ship orders anywhere in the United States while cutting normal delivery times in half. A Boyd storefront representative can help coordinate B460XT framing, glazing method, historic grids, muntins, vents, entrances, mullions, finishes, accessories, drawings, specifications, and installation requirements.

When to Use the Series B460XT Storefront System

• Commercial storefront projects requiring XT high-performance aluminum framing with a dual pour-and-debridge thermal barrier.

• Low-rise, ground-level, single-story glazed openings requiring a front-set glass plane, 2" sightline, 4.5" frame depth, and glazing up to 1" thick.

• Projects requiring a front-set glass plane that mimics curtain wall and creates a seamless, consistent exterior appearance.

• New construction, storefront replacement, adaptive reuse, and energy-conscious building-envelope projects requiring coordinated thermal storefront framing and entrance systems.

• Cost-effective historic renovations requiring compatibility with Boyd historic grids, applied muntins, finish coordination, and a front-set storefront profile.

• Projects requiring outside-glazed, inside-glazed, or structural silicone glazed storefront details.

• Projects requiring screw-spline or shear-block construction and heavy-duty, corner, variable, three-way, or four-way mullion configurations.

• Storefront elevations requiring compatible Series SV100 zero-sightline awning or casement project-out vents.

• Storefront entrance packages requiring coordination with Boyd D350XT medium-stile or D500XT wide-stile thermally broken entrance doors.

• Storefront and accessory orders where Boyd's maintained inventory, careful packaging, nationwide shipping, and reduced normal delivery time support the project schedule.

Choosing an XT or Standard Boyd Storefront System

You are viewing the B460XT front-set system in Boyd's XT high-performance thermal storefront line. Storefront selection should begin with the required thermal strategy, front-set or center-set glass plane, glazing method, frame dimensions, glazing thickness, historic-grid requirements, entrance type, ventilation, mullion configuration, finish, water management, wind load, and opening conditions. Review the related systems below when the project requires center-set XT framing, standard thermal storefront framing, non-thermal framing, a dedicated historic-replica profile, zero-sightline ventilation, or coordinated XT thermal entrance doors.

Common Series B460XT Storefront Coordination Items

• Thermal strategy: Coordinate the dual pour-and-debridge thermal barrier with the glazing package, thermal entrance doors, adjacent wall conditions, energy-code criteria, condensation requirements, U-factor or U-value targets, SHGC requirements, and perimeter details.

• Front-set glass plane: Confirm that the front-set B460XT appearance and glazing position match the architectural intent. Review B450XT when a center-set glass plane and traditional storefront appearance are required.

• Storefront versus curtain wall: B460XT creates a curtain-wall aesthetic but remains a storefront framing system. When an elevation spans multiple stories, crosses floor lines, or requires curtain-wall anchorage and movement accommodation, review a curtain-wall system instead.

• Glazing method: Select outside-glazed, inside-glazed, or structural silicone glazed details and coordinate glass access, installation sequence, sealants, gaskets, stops, structural silicone requirements, inspection, replacement glazing, and adjacent conditions.

• Glazing makeup: Confirm the complete glass makeup, 1-inch maximum thickness, safety glazing, coatings, tint, heat treatment, spacers, edge conditions, setting blocks, glass availability, thermal targets, and glazing responsibility.

• Fabrication and shop drawings: Select screw-spline or shear-block construction and coordinate extrusions, fasteners, shear blocks, drill requirements, cut lists, shop drawings, frame assembly, opening identification, and field installation sequence.

• Historic grids and muntins: Confirm the grid pattern, lite divisions, muntin profile, dimensions, attachment, joints, finish, glass replacement strategy, prefabrication scope, field installation, alignment across frames, and coordination with entrance doors.

• SV100 vent integration: Confirm awning or casement project-out operation, vent dimensions, surrounding glazing pocket, screens, operating hardware, interior and exterior clearance, drainage, flashing, finish, and installation details.

• Mullions and spans: Coordinate opening width and height, vertical- and horizontal-mullion spacing, heavy-duty, corner, variable, three-way, or four-way configurations, wind pressure, glass weight, dead load, reinforcement, expansion, anchors, and intermediate horizontals.

• Air, water, and structural performance: Coordinate 0.06 air infiltration at 6.2 psf, 12.00 psf water resistance, and 25.00 psf structural performance with opening dimensions, mullion spacing, reinforcement, glazing, anchorage, and installation conditions.

• Entrance integration: Coordinate D350XT or D500XT door selection, entrance frames, single doors or pairs, sidelites, transoms, thresholds, panic hardware, closers, access control, clear openings, accessibility, 1-inch glazing, thermal continuity, and finish.

• Water management: Coordinate subsill, end dams, sill flashing, weep paths, glazing pockets, perimeter sealants, backer materials, thresholds, adjacent construction, and field drainage conditions.

• Anchoring and perimeter conditions: Verify rough openings, field dimensions, substrates, anchors, fasteners, shims, perimeter joints, sealants, dissimilar-material isolation, trims, adaptors, and accessory scope against approved shop drawings.

• Finish and protection: Coordinate anodized or painted finish, color samples, grids, muntins, entrance hardware, vents, accessories, exposed fasteners, adjacent materials, jobsite protection, cleaning, and touch-up requirements.

• Inventory, shipping, and installation sequence: Provide storefront and accessory quantities, required delivery date, opening priorities, packaging or sorting needs, site access, storage plan, fabrication responsibility, and installation sequence when shorter delivery times are needed.
