Garage Door Types: Steel, Insulated, Wood, and Openers
Compare garage door families: steel sectional doors, insulated doors, wood and custom doors, and garage door openers, with how each is built, insulated, and operated.
Aluminum and Glass Garage Doors: Frames, Glazing and Finishes
A full view aluminum and glass door is built from a lightweight rust resistant frame that carries interchangeable glass, acrylic or solid panels, which is what gives it its modern look and its wide range of privacy and finish options.
System typeCarriage House Garage Doors: Steel Construction and Insulation
A modern carriage house door delivers the swing out barn door look on a standard overhead sectional, using a layered steel body with a woodgrain composite overlay so it gets the appearance of wood without the upkeep.
System typeGarage Door Openers: Chain, Belt, Screw, and Wall-Mount Drives
Drive type sets how loud and how smooth an opener runs, while federal safety rules require entrapment protection such as photoelectric sensors on every residential opener.
System typeHigh Wind Rated Garage Doors: Design Pressure, DASMA 108 and 115
A high wind rated door is specified by the pressure it can hold, not the wind speed it faces, and it is proven with the ANSI/DASMA 108 pressure test and, in debris zones, the ANSI/DASMA 115 impact test.
System typeInsulated Garage Doors: R-Value, Polyurethane vs Polystyrene
Door R-value depends on the insulating core, the thickness, and how it is measured, and polyurethane and polystyrene foams sit at very different points on that scale.
System typeJackshaft Wall Mount Openers: How Side Mount Drives Work
A jackshaft opener bolts to the wall beside the door and turns the torsion bar directly, which frees the ceiling for storage or high lift tracks and is why it needs a torsion spring rather than a trolley and rail.
System typeSteel Sectional Garage Doors: Layers, Gauge, and Finish
Steel sectional doors are sold in single, double, and triple-layer builds, with thicker steel and injected insulation moving up the price and performance ladder.
System typeWood and Custom Garage Doors: Look, Maintenance, and Cost
Real wood and custom doors deliver a look steel cannot match, but they trade that for higher cost, lower factory R-values, and ongoing refinishing.
