| Ally: |
Aluminium. |
| Anti lift Device: |
A device usually fitted on sliding patios or
double doors, and fitted over an opening sash in-between the
sash and frame profile. |
| Anti Sun Glass: |
A range of low to medium performance tinted
glass, designed to reduce heat gain. The solar control properties
and colour densities can vary depending on thickness. Available
in Blue, Bronze, Green and Grey tints. |
| Annealed Glass: |
Standard glass (not safety glass). |
| Armoured Cylinder: |
A high security cylinder that is protects against
drill attack. |
| Austrian Bar: |
Thin aluminium roll formed bar that is inserted
between the two panes of a sealed unit to give a leaded glass
effect. Easier to clean than leaded windows. Usually available
in white, gold, bronze and grey. |
| Automatic Deadlocking: |
A small auxiliary bolt situated next to the
main bolt that hits a striking plate or staple and is pushed
in every time the door is closed. This action automatically
holds the main bolt in the locked position. |
| Backplate: |
The plate, fixed on a door, to which the moving
parts of a lock or latch are attached. |
| Bay Window: |
Bay windows are internally recessed and form
an angled projection from the building that rises up from
the ground on the first floor. A Canted Bay Window has straight
front and angled sides. |
Bead:
|
The section designed to secure
the double glazed unit in place. |
| Bow Window: |
Bow windows are rounded projections, often
formed of the window glass itself. |
| Casement Window: |
Traditional outward opening window |
| Cat Flaps: |
Can be fitted at the time of manufacture |
| Child Restrictors: |
Attachments to large openers preventing them
being opened far enough for a young child to climb or fall
out. They can easily be disabled by an adult to allow the
window to fully open but in truth, should only be considered
toddler proof. |
| Cill (Sill): |
A window will normally have two cills, one
internally usually referred to as the window board and one
external one. The function of the external cill is to disperse
water that has run down a window. |
| Claw bolt: |
A type of deadbolt having claws that swing
out sideways when the bolt is shot. These locks are usually
fixed to sliding doors. |
| Deadlock: |
A single bolt mortice lock, which can be used
in addition to a standard cylinder rim lock on the front door. |
| Deadlocking: |
On cylinder rim locks with this function, when
you leave the house and close the door, you insert the key
in the cylinder lock and turn anti-clockwise. This deadlocks
the bolt and stops it from being pushed back. |
| Delayed Action: |
A door closer that holds the door in the open
position for a number of seconds before the closing action
commences. This is ideal for use by the handicapped, the aged
and people with prams, trolleys etc. |
| Desiccant: |
Desiccant is moisture-absorbing beads that
fill the spacer bar within the construction of the double
glazed unit. The desiccant will absorb any trapped organic
moisture or vapour that may cause condensation between the
panes of glass at a later date. |
| Door restrictors: |
Used for outward opening doors to prevent them
slamming shut in windy conditions |
| Dormer windows: |
Windows that are usually set upright in a sloping
roof. They require extra trims or liners around the outside |
| Double locking: |
The means by which the latchbolt on a cylinder
rim lock is deadlocked. Upon leaving the house you insert
the key in the outside cylinder and turn anti clockwise. This
locks the inside handle rendering it unopenable until the
key is reinserted into the outside cylinder and so preventing
unauthorised entry by someone breaking adjacent glass, reaching
in and turning the handle. |
| Double Glazed: |
see sealed units |
| Dual Seal: |
Dual seal is a black butyl rubber based hot
melt compound that is specifically designed for the use as
a primary seal and spacer bar adhesive in the construction
of insulated glass units.The sealant is applied at high temperature
to the spacer bar by using hot melt extrusion equipment, and
then the spacer bar is applied to the two leaves of glass.
To complete the construction of the unit a two part fast curing
polyurethane compound specifically designed as an edge sealant
is applied to the perimeter of the insulating glass unit. |
| Espagnollette: |
A device, which is fitted to the sash (opening
window) and is operated via the handle to lock the window. |
| Face Plate: |
A strip of metal fixed to the outer edge of
a mortice lock, which fits flush with the door edge. |
| Fire Escape Hinges: |
These allow windows to open further than conventional
friction hinges and therefore provide a better means of fire
escape. |
| Fixed Unit/Fixed Light: |
A non-opening window. |
| Flag Hinge: |
A type of door hinge that is surface mounted
and offers horizontal and vertical adjustment. |
| Frame Fixings: |
A device for fixing the frame of any type of
door or window to the fabric of the building. |
| Georgian Bar: |
A grid system designed to look like a traditional
Georgian window but that is easier to clean. It is normally
made of roll formed aluminium and painted white, although
a variety of colours are available including wood grain in
various shades. The bars sit between the 2 panes of glass
in the double glazed unit. |
| Glazing Gasket: |
This is normally a rubber gasket that sits
between the glass and any uPVC or aluminium components. |
| Head: |
The top of a window or door. |
| Handle: |
This operates the locking device to secure
the window via the Espagnolette. Locking and non-locking types
are available. |
| Insulated Glass Units: |
see sealed units |
| Jamb: |
The vertical component of a doorframe |
| K-glass: |
Manufactured by Pilkington with an almost invisible
coating on the inside of the inner pane to reduce heat loss
through the window. A brand name for low-e glass. |
