Glass Walls for Flood Defence


The IBS glass wall flood defence system (or flood glazing) is used where permanent flood protection is required but where the visual impact of a traditional flood defence wall is not suitable for the surrounding area. The system has been used extensively throughout Europe with individual panel lengths in excess of 3m and heights in excess of 2m.

The IBS glass wall is extremely robust and uses the same aluminium post profiles and EPDM seals as the tried and trusted IBS demountable flood defence system. All parts are interchangeable, easily replaceable and maintenance free (apart from the occasional clean if the panels experience a build up of dirt).

Flow Control Systems
Glass System

In order to achieve the required project specific static and impact loads the IBS glass wall consists of two or more central structural glass panes (according to size and loads), bonded together with intermediate layers made of highly tear-resistant, transparent polyvinyl-butyral foils (PVB). Protection of these structural panes is achieved by the use of ‘sacrificial’ panes of glass, which are located on either side of the structural glass and also bonded with PVB. These ‘sacrificial’ panes cannot be included when calculating the strength of the glass system and their main purpose is to protect the structural panes from impacts and/or vandalism, thus ensuring that the integrity of the flood defence is maintained.
Glass Types

The two types of glass used in the construction of our glass wall are: float glass (rolled glass) or pre-stressed glass (PG). PG has four to five times higher bending tensile strength than float glass and if broken due to excess external force, disintegrates into blunt-edged, loosely connected crumbs that pose a much lesser risk of injury than the sharp-edged shards of float glass. PG is made from float glass by controlled heating to approx. 620°C and fast subsequent cooling.

System Construction

The glass is surrounded on four sides by extruded sections of aluminium with a profiled EPDM seal (similar to that seen in double glazing units). The finished aluminium framed glass panel sits in an aluminium post at each end and is allowed to float between the two to allow for construction tolerances, expansion and contraction. Ideally, posts are equally spaced along the length of the flood defence wall to maintain a consistent glass panel length and improve the aesthetics of the system.
For higher static and impact loads, additional central supports can be added to the system which then disperse load to the foundation wall (see image below).
