Which Size Garage Door

 

1. Up and over garage door

All types of up and over garage doors are measured as an INTERNAL FRAME SIZE - e.g. timber to timber width (internal frame size = 7' 0"). Floor to underside of timber crossbar (internal frame size = 6' 6"). This means you need a 7' 0" wide x 6' 6" high garage door.
Door sizes are always expressed with the WIDTH first.

The actual Door Panel size will be slightly SMALLER than the 7' 0" x 6' 6" in order to be a perfect fit to suit the internal frame size of 7' 0" wide x 6' 6" high.

frame

  • Most up and over garage doors require a 70 mm square timber goalpost frame OR factory fitted steel frame. The door size does not include the size of this frame.
  • There are two ways of fitting an up and over garage door. Please see diagram A and B.
between brick fit
rear brick fit

The most popular way of fitting a new garage door and - if required - a new frame is to purchase a door complete with a steel frame - which is pre-fitted to single size doors in the factory. (New timber frames can also be purchased). This allows a very quick and easy installation on site. The Pdf table below shows exact overall and internal frame sizes for the most popular brands of door: Garador, Hormann, Wessex and Woodrite on super gear.

frame sizes

With this information you can check if the framed door/frame can fit in between or onto the rear of the brickwork opening. NB: for a between the brickwork fit you should allow a tolerance to the overall frame size shown - ideally 10mm on the overall width and 5mm minimum on the overall height.

3.Non insulated roller garage doors.

roller
If the headroom available is less than that required in the diagram, the roller can be fitted lower, but the drive through height will be reduced. Also, the curve of the roller may become evident when viewed from the front with the door shut, if the door is fitted too low
roller
For automatic single doors, a minimum of 110mm is needed on the motor end of the door.
N.B. Single doors for opening up to 11’ wide are made 2” wider than the opening, 1” of curtain sits in the guide channels each side. Double doors over 11’ wide are made 4” wider than the opening, 2” of curtain sits in the guide channels each side.

4. Insulated roller garage doors.

  • The door is usually installed on the rear of the brickwork opening.
  • The headroom needed for the full box, which houses the roll, is normally 300mm square and the side room for the guides is 90mm each side. 70mm guides on request. If 300mm of headroom isn’t available the neat box front will act as a facia.
  • For very limited headroom situations the Compact model with 55mm slats fits into a 205mm box housing. This model has 68mm guides.

The three methods of fitting this product are as follows:-
1. On the rear face of the brickwork opening (most popular) - looks good, box and guides are hidden. *
2. Between the brick pillars and underneath the lintel - maximises garage length but reduces entrance height and width. *
3. On the front of the brickwork - maximises garage width, height and length. *

5. Side-hinged garage door:

  • Steel and GRP (glass fibre) side-hinged garage doors come pre-installed to a fully finished goalpost frame.
  • Timber side-hinged garage doors come as 2 loose leaves for on-site fitting to a separate goalpost frame.
  • Most side-hinged garage doors are fitted between the brick pillars (see diagram below). This allows the doors to open past 90° without the doors hitting the pillars.
    between brick fit
  • All GRP side-hinged and Cedar side-hinged are made-to-measure as standard at no extra cost. All we need are your brickwork opening sizes.......
  1. Brick to brick width
  2. Floor to underside of lintel height
  • Garador steel side-hinged doors (pre-framed) come in a range of standard sizes. The chart below shows internal frame sizes and external frame sizes. To check if they will fit your opening you need minimum 5mm tolerance each side and above between your brickwork and the external frame size. Made-to-measure sizes also available.
