Product Details
The 48 x 80 exterior door is built from 6063-T5 aluminum with a 35–44 mm polyamide thermal break. This aluminum exterior door 48x80 can be configured as a single leaf, a 36-inch active with 12-inch sidelight, or a 2x24-inch French double. Opening types cover swing, pivot, heavy-duty sliding, and bifold, each featuring a triple EPDM seal and a multi-point lock.
Compared to residential doors, this heavy duty entry door withstands wind loads to Grade 8 and water tightness to Grade 5. Insulated glazing achieves U-Factors from 0.27–0.32, with select assemblies as low as 0.18. Smart access readiness and ADA-compliant thresholds ensure it meets modern commercial demands for security and code compliance.
Product Features
Thermal Break Performance: Polyamide strips of 35–44 mm reduce heat transfer, achieving U-Factors down to 0.18 and making this an energy efficient commercial door that lowers conditioning expenses.
Wind and Water Resistance: Built to Grade 8 wind (5 kPa), this heavy duty entry door protects building envelopes in exposed locations.
Multi-Point Security: Six-point locking with 304 stainless hooks deters intrusion; Class C cylinder adds insurance for high-theft-risk areas.
Configurable Design: Leaf layouts, opening style, and threshold type adapt to project drawings—no need to alter structural openings.
All-Weather Sealing: Triple EPDM gaskets maintain air tightness of 1.2 m³/(m·h) and prevent drafts, even under thermal movement.
Smart Access Ready: Prepped for fingerprint, card, or BMS integration, the frame routes wiring cleanly for future building management upgrades.
Customizable Styles
Glazing Choices: Low-E, laminated, tempered, insulated double/triple with argon, reflective, or tinted glass available to tailor thermal and acoustic performance.
Frame Finishes: Powder coat, anodized, or PVDF in RAL custom colors; suitable for architectural coordination and long-term exterior durability.
Leaf Configuration: 48x80 opening as a single door, 36″ + 12″ sidelight, or 2×24″ double—determine by traffic flow and accessibility needs.
Opening Mechanism: Swing, pivot, sliding, or bifold; each engineered with hardware matched to maintain weather sealing and durability.
Threshold Adaptation: Standard aluminum thermal break or ADA low-profile sill with integrated seal for smooth passage and energy conservation.
Hardware Accessories
Multi-Point Lock: Six-point 304SS hook lock with anti-pry cylinder secures the leaf; available with thumbturn or keyed operation.
Concealed Hinges: Adjustable concealed hinges deliver smooth swing and a clean appearance, supporting heavy door weights.
Triple Seal Gaskets: Continuous EPDM seals on frame and sash block air and water, compensating for expansion and contraction.
Handle and Smart Module: Long commercial handle with optional fingerprint/card reader; wiring channel pre-installed for access control.
Weatherproof Sill: Thermally broken aluminum sill with flexible seal prevents water penetration and meets accessible route requirements.
