Types Of Garage Doors
Panel garage doors combines the look of wood grain textured panels with the durability of high quality corrosion resistant coloured steel. From the closed position a single panel door will slide up and overhead on rails to the fully open position. A disadvantage of monolithic panel doors is that the swing up arc of the door occurs partially outside the garage. This means a vehicle must stop and park several feet in front of the door to avoid being hit by the garage door when it is opened.
Roller doors are usually constructed of corrugated steel. Other materials can be used (eg; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door will have a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.
Sectional garage doors are usually constructed of six to eight panels and slide up and overhead. Sectional doors occupy exactly the same amount of internal garage space as a monolithic door. Sectional doors have two distinct advantages over single panel monolithic doors:
- Sectional doors do not require any space outside the garage to open. A vehicle may park very close to the garage before opening the door.
- Each panel of a sectional door has its own connection to the door track. This increases reliability and robustness compared to a monolithic doors which has only a couple of track connections for the whole panel.
Sectional garage doors can be made out of many materials, but steel, aluminum, wood, and vinyl (polyethylene) are the most popular materials. A few manufactures are making energy efficient garage doors by putting foamed-in-place polyurethane insulation in monolithic panel and sectional garage doors
Tilt Garage Doors comprise of a one piece tilting panel, fitted with pivoting arms at both sides of the opening, which moves out and up from a vertical position into a horizontal position. These allow almost any material to be used to make a garage door and offer one of the lowest possible headroom requirements.
