Innovative
Glazing Solution for Secure Hospitals
Merseyside-based
specialist fabricator BRITplas has developed an extraordinary
window solution for secure hospitals and similar healthcare facilities
using Pilkington Activ self-cleaning glass as one of its major
components.
The SafeVent Window was developed after BRITplas was approached by
Laing O'Rourke to provide windows for the Rathbone Low Secure Unit
on behalf of Merseycare NHS Trust.

The
Alpha Hospital at Sheffield utilises SafeVent windows featuring Pilkington
Activ self-cleaning glass throughout, just one of a growing
list of hospitals to specify the window.
Laing
O'Rourke had approached a number of manufacturers to source windows
for the hospital that would provide an appropriate level of security
whilst retaining the appearance and general performance of conventional
windows. BRITplas was the only company to provide an appropriate solution.
The BRITplas SafeVent window has an in-line horizontal sliding action
which allows up to 50% of the window area to open without the need
for hinges, locking points, levers or handles that may be used as
ligature points. It has an easy sliding action to allow use by even
frail patients whilst also preventing use as a ligature anchor point.
The SafeVent's open area is covered with a sheet of stainless steel
punched with holes to make a mesh. Although, in description, this
sounds austere it is actually surprisingly discreet. The mesh prevents
escape and the passing of contraband while allowing fresh air, natural
sound and light to enter the room.
Standard glazing comprises of a 10mm toughened glass on the internal
surface, a 10mm argon-filled air gap and an 8.4mm laminated section
to the outside.
Pilkington Activ is utilised due to the difficulties presented
in cleaning the windows because the Safevent Window cannot be opened
conventionally and the external pane of the sliding section is fixed
behind a mesh. The self-cleaning action of Pilkington Activ
ensures that through exposure to ultra violet light organic soiling
of the glass surface is continuously broken down and loosened. By
occasionally spraying water through the top of the mesh in short bursts
the hydrophilic action of the glass causes the water to 'sheet' and
therefore take the loosened dirt with it as it runs off.
As proven by extensive and violent testing the SafeVent Window is
highly secure, whilst also complying with thermal performance in accordance
with Part L of the Building Regulations. Of key importance however
is that the windows provide an appearance and performance close to
that of conventional frames. The window may be manufactured in any
framing material and with a choice of glazing options, including solar
control. Frames may be manufactured to almost any size including patio
door dimensions.
Kevin Gorman, Managing Director of BRITplas and designer of the SafeVent
Window, says that Pilkington Activ was a key component of the
development of the product: Pilkington Activ allowed us
to develop a solution that is very simple in its principles and execution,
but which more than satisfies the strict criteria of the client.
Since the SafeVent system was used throughout Rathbone LSU five other
NHS Trusts and two private hospitals have installed the product, including
Pennine Care NHS Trust, Oxford & Buckinghamshire NHS Trust, Derbyshire
NHS Trust, 5 Boroughs NHS Trust and Gloucestershire NHS Trust. Private
hospital groups to have installed SafeVent featuring Pilkington Activ
are Alpha Hospitals and Priory Healthcare. A further eleven projects
are being installed with others under discussion.
