Alumitrex™ 39-1/2" x 121-3/4" Storefront Glass Entrance System - 36" x 84" LH Medium Stile Door with 36" Transom - Exterior Pre-Cast Concrete Wall - 1/4" Tempered Safety Glass, Standard-Duty, Clear Anodized - Made in USA (3-4 Week Production)

A complete, exterior-compliant storefront entrance system engineered for pre-cast concrete wall applications. Combines a 36" x 84" LH medium-stile door with a 36" transom window above for added daylight and visibility. The door ships pre-glazed. The entrance frame is pre-fabricated and requires field assembly. Transom glass ships in a separate crate and is field glazed after the frame is anchored and sealed. Total system frame size: 39-1/2" x 121-3/4".

Compliance & Intended Use

  • Exterior application with dedicated sill and head flashing details for weather management.
  • ADA approach and operability supported when adjusted per A117.1.
  • IBC storefront entrance assembly practices for non-fire-rated openings.
  • Hardware: Grade 1 where applicable; UL Listed and ANSI/BHMA certified components (A156 series).
  • Standard-duty construction for moderate-traffic commercial entrances.

Aluminum storefront systems are generally non-fire-rated. If a rating is required, select a listed hollow metal/fire-rated assembly.

  • Transom glass: 1/4" tempered safety glass, crated separately and field installed after frame is set and sealed.
  • Exterior sill package: commercial threshold plus sill flashing to integrate with the wall’s drainage plane.
  • Head flashing/drip edge components to shed water at the transom/head condition.
  • Primary hardware set: Grade 1 closer (A156.4), entry lock/latch (A156.5), interior push bar and exterior pull (A156.6), top and bottom pivots/hinges.

Wall Type & Exterior Weatherproofing - Pre-Cast Concrete

Designed for pre-cast concrete wall panels with joints, reveals, and embedded hardware. The included threshold, sill flashing, and head flashing/drip edge integrate with commercial sealants to help shed water at both the sill and transom head.

  • Coordinate with the GC/engineer for embed plates/inserts or receiver angles at jambs and head where required.
  • Anchorage: use engineer-approved mechanical expansion or adhesive anchors into pre-cast, or fasten to embeds/inserts per project details; verify edge distances and minimum embedment.
  • Prepare a flat, level, structurally sound sill; bed threshold in continuous sealant and integrate sill flashing with positive slope to exterior.
  • Treat adjacent panel control/expansion joints with backer rod and compatible sealant; allow for anticipated movement.
  • Shim jambs, head, and transom mullions to maintain plumb, level, and square; verify clear opening and reveal uniformity.
  • Use compatible sealants for pre-cast substrates; prime where specified by the manufacturer.

Anchors, embeds, and structural attachment are by installer to match site-specific panel design and engineer requirements.

Typical Installation Sequence

  1. Verify rough opening and layout; confirm system frame size 39-1/2" x 121-3/4".
  2. Dry-fit components; assemble the pre-fabricated frame (KD) including transom section per instructions.
  3. Install pan/sill flashing; bed threshold in continuous sealant; set and plumb the frame.
  4. Anchor jambs, head, and transom mullions to pre-cast via embeds/inserts or approved anchors; seal perimeter joints.
  5. Install head flashing/drip edge above the transom; integrate with WRB/through-wall flashing where detailed.
  6. Adjust closer and hardware to ADA parameters; verify smooth operation and latch engagement.
  7. Field glaze the transom: set blocks, install glass from the crate, apply glazing, secure stops; verify weatherseals.
  8. Final QA: check clear opening, sweep/latch speeds, and water-shed at sill and head.

Popular Options & Upgrades

  • Insulated, laminated, tinted, or low-E glass for door/transom.
  • Keyless entry, electric strike (non-rated), access control prep.
  • Alternate anodized or painted finishes.
  • Enhanced weatherseal packages for high-exposure facades.
