Single Skin Roller Doors - Measuring Guide

Before taking any measurements it is essential to understand that Gliderol roller doors can only be installed to the internal face of the opening or behind a suitable structure such as a timber framework. For more information read the Gliderol single skin door technical details page.

Measure the Width

Measure the structural opening width (brick to brick) in mm (we advise you to measure top, middle and bottom to allow for any deviations in the opening. Use the biggest measurement for the width).

Meausure the Height

Place the tape on the floor and measure from this point to the underside of the lintel. Check the opening in three places to check for any deviation in dimensions. Use the biggest measurement.

Combine the Measurements

This will give you your ordering size (width x height) In the case of the illustrated drawings a 2010mm (w) x 2110mm (h) will be ordered.

Checking the Headroom and Side Room

You will now need to need to check the side room and headroom space you have available. Using the below image as a reference, measure in three places to check for any deviation in dimensions. This time use the smallest measurement.

Headroom Requirements

The minimum clearance required above the structural opening is:

• OPENING HEIGHT up to 2135mm - HEADROOM REQUIRED 430mm
• OPENING HEIGHT up to 2440mm - HEADROOM REQUIRED 450mm
• OPENING HEIGHT up to 2750mm - HEADROOM REQUIRED 450mm
• OPENING HEIGHT up to 3000mm - HEADROOM REQUIRED 470mm

Side Room Requirements

• Structural openings up to 3350mm wide require 90mm each side of the opening plus an additional 20mm on the side the motor fits (if automated).
• Structural openings over 3350mm wide require 150mm each side of the opening plus an additional 20mm on the side the motor fits (if automated).

NB* 2135mm High doors wider than 3400mm will require 450mm of headroom

Check The Horizontal Space

Finally you will need to ensure enough horizontal space is available to conceal the door roll from view when looking from the outside.

The minimum horizontal clearance required is:

• OPENING HEIGHT up to 2135mm - CLEARANCE REQUIRED 500mm
• OPENING HEIGHT up to 2440mm - CLEARANCE REQUIRED 540mm
• OPENING HEIGHT up to 2750mm - CLEARANCE REQUIRED 540mm
• OPENING HEIGHT up to 3000mm - CLEARANCE REQUIRED 560mm
