Safety Glass Regulations
are rules and regulations as to what types of glass can
be installed into windows, doors and other glazing locations.
Here is our guide to help you understand where you must
look to install the correct safety glass to your home or
To comply with the Building Regulations glazing
requirements or also known as ‘Critical
Locations’ there must
be safety glass or safety guards in place to protect people
from injury. The
most likely locations for accidents caused by glass breakage,
which could result in cutting and piercing injuries
are in doors,
side panels, low windows and low level glass in walls and
Safety glass should be fitted in all doors and other windows or glazed areas that are lower than 800mm from the floor level. Glass panels less than 250mm wide can be fitted with 6mm glass or laminated glass instead of toughened glass.
Critical Locations are considered to be:
1. Glazing in doors – Glass which is wholly or partially
within 1500mm from floor level. As the drawing
below shows, any glass in doors that does not start over
1500mm from the floor must be safety glass.
2. Glazing adjacent to doors – Windows/side panels
wholly or partially within 300mm of the edge of a door and
or partially within 1500mm from floor level must be safety
3. Low Level Glazing – Not covered in (1) OR (2) ABOVE
- Other glazing that is wholly or partially within 800mm
from floor level. This means that windows that are not located
within 300mm of a door must use safety glass if the bottom
is within 800mm of the floor level.
in ‘Critical Locations’ should either:
1. Break safely, if it breaks, i.e. laminated or toughened
Class C safety glass complying with BS6206. Or if it is installed
in a door or in door side panels and has a width or height
exceeding 900mm it should be Class B of BS 6206.
Ordinary wired glass is not safety glass.
For double-glazed sealed units, the rules apply to both
pieces of glass.
All safety glazing should be permanently marked in accordance
with BS6206. The markings should be still visible after the
glass has been fitted and the beading and pointing has been
most common form of safety glass (and the lowest cost)
is 4mm toughened glass. This glass is used for almost
all residential safety glazing and 4mm toughened comes
in a large range of obscure
patterns as well as
the energy saving glass - Pilkington K glass.
Normal glass (annealed) can also be used as a safety
glass in some instances as long as the glass is thick
enough. As an example 6mm annealed glass can be used
in doors up to a glazing width of 250mm but must not
exceed 0.5sq.metre in area.
Other annealed glass regulations
are as follows...
8mm glass can be used as safety glass if it does not
exceed 1100mm in any direction
10mm glass can be used as safety glass if it does not
exceed 2.25m in any direction
glass can be used as safety glass if it does not exceed
3.0m in height or 4.5m in width
glass can be used as safety glass in any size opening
