Vision Panel Technical Information

Regulations for Vision panels & Health and Safety.

When fitting Vision panels Knowles, according to regulations, will be measuring the distance from the bottom of the door to the glass. With this measurement, we subtract the top of the glass to the top of the door. This calculation (below) is the ‘max height’ for allowance. To create the maximum vision panel size incompletion the formula is as follows;

Example: Door size 2040 x 926 x 54 (Height x width x Depth). 2040-331-150=1559

926 (Width) – 150 (measurement from one side) – 150 (measurement from another side) = 626 *The only thing that will change is the width of this sum. 926-150-150=626

This will leave you with max glass VP size of 1559 x 926. Subject to door size.

Certification on Vision Panel Kits

Due to the components being sent out for assembly we cannot certify them as fire rated as we would not be assembling the VP on site. For more information on how to order your door, read our door reference guide.
