Insulated Washbay Garage Doors

Why It Works

• 3" insulated sandwich-style panels rated R-17.
• Maximum thermal protection for climate-controlled wash bays.
• Corrosion-resistant materials throughout.
• Heavy-duty construction for daily commercial use.
• Warmer interior surfaces dry faster between cycles.
• Protects livestock, product, vehicles, and equipment, so ag buildings get the same door the wash bays do.

How the Section Is Built

The section is a true thermal sandwich: closed-cell insulation bonded between steel skins, with thermal breaks at every path cold could take through the panel.

• ▪ Tongue-and-groove joint locks sections together and closes the meeting-rail gap the wind would otherwise find.
• ▪ Vinyl thermal break separates the interior and exterior skins, so cold has no straight metal path through the panel.
• ▪ 3" extruded closed-cell polystyrene core, pressure bonded to the skins, rated R-17. It absorbs far less moisture than bead-board insulation, which matters in a room that is wet every day.
• ▪ Hot-dipped galvanized steel skins on both faces, pebble textured.
• ▪ Bottom astragal rides in an aluminum holder and seals the floor line.
• ▪ Weatherstripping between each section keeps the stack weathertight from top to bottom.

Engineered for the Environment

Insulation That Holds Its R-Value

Extruded, high-density, closed-cell polystyrene keeps its R-value over time and absorbs far less moisture than expanded bead-board type products, which matters in a room that is wet every day. It is pressure bonded to the skins, so the panel works as one piece.

Commercial Steel Skins

Interior and exterior skins are commercial-grade pebble-textured steel, roll-formed from hot-dipped galvanized stock, with five section colors to choose from.

Rails That Shed Water

Tongue and groove meeting rails are beveled to shed moisture and eliminate water traps, which reduces section delaminating caused by freezing.

Heavy-Duty End Stiles

Commercial 16 ga galvanized steel with a vinyl thermal break, so the stile is not a highway for cold straight through the section.

Thermal Barriers Throughout

Thermal breaks between the interior and exterior skins, at the end stiles, and in the between-section seals give the door a thermally tight seal instead of a well-insulated panel with cold edges.

Hardware Options

Platinum, Gold, and Silver hardware packages are offered, and stainless packages extend service life where chemistry and humidity are constant.

Counterbalance: How the Door Carries Its Own Weight

Insulated washbay doors run a torsion spring counterbalance matched to the section weight and the bay's cycle count.

Torsion Spring System

High-cycle models rated up to 100,000 cycles are available, in standard hot-dipped galvanized wire or rust-resistant stainless steel wire for daily washdown duty.

Choose it when: Every insulated washbay door. Spring selection follows the daily cycle count.

Hardware Package Options

Select the hardware package that fits your building's exposure level. American Garage Door Supply includes heavy-duty hardware as standard across every tier.

Build It for Your Bay

Every door is configured to order. These are the options we quote most often.

Window Lites

Insulated glass lites bring daylight into the bay: three lites across a 10' or 12' door, four across 14', five across 16', in 7", 12", or 15-1/2" heights. A full-vision insulated glass section is also available.

Five Section Colors

Choose from five section colors so the door matches the building. Ask for the current color chart when you quote.

Stainless Hardware Packages

Track, springs, bearing plates, bearings, shafts, cable, face hardware, and fasteners in stainless steel for bays where chemistry never lets up.

High-Cycle Springs

Spring packages rated up to 100,000 cycles for automatic washes and high-traffic bays.

Brush Weatherseal

Perimeter brush seal upgrade tightens the opening against wind-driven spray and heat loss.
