Door & Window Options for Every Application

Doors and windows serve critical functions in modular buildings beyond basic entry and light. They provide fire protection, sound isolation, security, visibility, natural light, ventilation, and accessibility. The right door and window selections transform a modular building from functional to exceptional — while the wrong selections create problems with noise, security, energy loss, and code compliance.

Material Handling USA offers the full range of commercial door and window options for modular buildings. Standard configurations include commercial steel doors with lever hardware, tempered glass windows, and panic-exit hardware on egress doors. Upgrades include fire-rated assemblies, acoustical doors, ballistic-rated entries, sliding glass systems, transaction windows, and electronic access control provisions.

Door & Window Options for Every Application

Door & Window Options

Select the right doors and windows for your modular building’s function, security, and code requirements.

Standard Commercial Doors

18-gauge steel doors with commercial-grade lever locksets, closer mechanisms, and weatherstripping. Available in 3-0 and 3-6 widths for ADA compliance. Single and double-door configurations.

Fire-Rated Doors

UL-listed fire-rated door assemblies from 20-minute to 90-minute ratings. Required where fire-rated wall separations occur. Include fire-rated frames, closer, and positive-latching hardware.

Acoustical Doors

STC 35–50 rated door assemblies for sound-sensitive applications. Solid-core or specialized acoustical door systems with perimeter seals, automatic bottom seal, and acoustical frame gaskets.

Windows & Glazing

Tempered safety glass in aluminum frames. Fixed, operable (sliding or awning), or full-height glazing systems. Double-pane insulated glass for exterior applications. Tinted, frosted, or clear options.

Transaction Windows

Counter-height windows with speak-through capability for shipping offices, guard booths, and reception areas. Include shelf, locked panel options, and bullet-resistant upgrades.

Specialty & Security Options

Specialty & Security Options

For high-security applications, we offer UL 752 ballistic-rated doors and windows from Level 1 (9mm handgun) through Level 8 (7.62mm rifle). Ballistic assemblies include rated glass, steel frames with ballistic overlap, and coordinated wall construction that provides equivalent protection. Guard booths, security checkpoints, and high-value storage facilities benefit from ballistic-rated entry systems.

Electronic access control provisions include electric strike prep, card reader mounting plates, and conduit for access control wiring. Overhead coiling doors and bi-fold doors are available for equipment access, vehicle entry, and large-opening applications. Sliding glass doors provide reception area access and natural light in office configurations.

Benefits of Proper Door & Window Selection

Code Compliance — Fire-rated doors, panic hardware, and ADA-width openings ensure your building meets all applicable building and fire codes.
Sound Control — Acoustical doors and sealed windows maintain the sound isolation that STC-rated wall panels provide — the door is often the weakest link in a sound-rated enclosure.
Security — From standard commercial locksets to ballistic-rated entries with access control, doors and windows are your primary security boundary.
Energy Efficiency — Insulated glass, weatherstripping, and proper door seals prevent conditioned air loss — maintaining HVAC efficiency and occupant comfort.
Natural Light — Strategic window placement reduces artificial lighting needs, improves occupant well-being, and provides visual connection to surrounding operations.
Durability — Commercial-grade hardware withstands thousands of daily use cycles — far outlasting residential-grade components in high-traffic modular buildings.

Frequently Asked Questions

What fire rating do I need for my doors?
Fire-rated doors are required where a fire-rated wall separation exists. The door rating must be at least 75% of the wall rating: a 1-hour fire wall requires a 45-minute fire door; a 2-hour wall requires a 90-minute door. Your local fire code and building plans specify where fire-rated assemblies are required.
Can windows be added to any wall panel?
Yes. Window openings can be cut into most modular wall panel systems. Factory-installed windows are recommended for precise fit and weather-sealing. Field-installed windows are possible but may compromise fire ratings or acoustical performance.
Do you offer bullet-resistant glass?
Yes. We offer UL 752-rated ballistic glazing from Level 1 through Level 8. Ballistic glass is typically 1–2 inches thick (depending on rating) and is installed in specialized frames with ballistic overlap to prevent penetration at frame edges.
What about overhead doors for equipment access?
We install overhead coiling doors (steel or aluminum), sectional overhead doors, and bi-fold doors for equipment access, vehicle entry, and large-opening applications. Openings up to 12 feet wide and 12 feet tall are available.
