Which size door?

Up and over garage door
Sectional garage door
Non-insulated Roller garage door
Insulated Roller 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 two most popular brands of door - i.e. Hormann and Garador.

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.

Cardale, Henderson and Wessex Door and Frame Sizes (examples)

Internal Frame size	Canopy Door Overall Frame	Retractable Door Overall Frame

7' 0" wide x 7' 0" high	Width - door size + 108mm Height - door size + 68mm	Width - door size + 136mm Height - door size + 68mm
8' 0" wide x 7' 0" high	Width - door size + 108mm Width - door size + 108mm	Width - door size + 136mm Height - door size + 68mm
14' 0" wide x 7' 0" high	Canopy not available	Width - door size + 136mm Height - door size + 68mm

NB: THIS WILL GIVE TIGHT OVERALL FRAME SIZES TO WHICH THE TOLERANCES MENTIONED ABOVE SHOULD BE ADDED (OVERALL 10MM ON THE WIDTH AND 5MM MINIMUM ON THE HEIGHT)

2. Sectional garage doors.

The size of a sectional door is expressed as an internal frame size
A fully finished steel frame comes with all sectional garage doors as standard
The steel frame of a sectional garage door fits onto the rear of the brick pillars
A between brickwork fit is possible if needs be - please call 01691 670394 for details

	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
	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).

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.
