Vision Panel Technical Information

Glazed apertures can be introduced to a door specification for reasons of safety, aesthetics or to permit the transfer of light. Vision panels can be selected from a range of popular configurations shown below or can be produced to order for a bespoke product.

Regulation for Vision Panels Health & Safety

When fitting Vision panels E & S W 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 Vision Panel size of 1559 x 926. Subject to door size.

Door Vision Panels for the protection against impact from and trapping by doors.

Approved Document K giving practical guidance on how to meet the requirements of the Building regulations 2010 incorporates Requirement K6: Protection against impact from and trapping by doors.

K6 (3) states, provision shall be made to ensure a clear view of the space on either side of a swing door (or gate). Requirement K6 does not apply to a) dwellings or b) any door (or gate) which is part of a lift. The requirement of (AD) K6 can be meet if measures are incorporated into the door design to prevent the opening and closing of doors presenting a safety hazard.

(AD) K6 Section10.1 – Safety features:
Doors (& gates) should be constructed in accordance with a) Indoor leaves and side panels wider than 450mm, include vision panels towards the leading edge of the door to provide as a minimum, the zone or zones of visibility shown in diagram 10.1(FZD0519/1).

(AD)K6 section 10.2- Hazards on access routes:
If, during normal use, doors (excluding fire escape doors ) swing out by more than 100mm towards an access route, protect them as shown in diagram 10.2 (FZD0520/1).]

DDA Regulation Act 1995.

The Disability Discrimination Act (DDA) works to protect people with disabilities – including blind and partially sighted people – from discrimination.

DDA Regulations for doors with vision panels require;

People should be able to see other people on or approaching the other side of doors to avoid the risk of collision. (There may be circumstances where for reasons of privacy or security this may not be appropriate or possible).

The diagram to the right shows the minimum requirements to satisfy Part M.
(Please note that this diagram is now shown in Part K of the Building Regulations, not Part M. It is referenced in Part M)
