Solutions for ‘Problem Glass’ in Buildings – Before, during and after installation

17 Oct

The main causes of ‘Problem Glass’ are MAD!

Moisture, Alkalinity and Dirt (MAD) can easily cause glass, exterior or interior, to become Problem Glass.  Glass is all around us and, when new, it promises visibility, clarity and cleanliness.  Unless glass is protected against MAD, it can easily break these promises before, during or after installation – with serious consequences for specifiers, fabricators, contractors, installers, building owners and occupants.

Problem Glass is any glass that has broken, or is likely to break, its original promises of visibility, clarity and cleanliness.  This causes glass to become increasingly difficult to clean and keep clean – a high-maintenance material of construction.  In spite of frequent and intensive cleaning, Problem Glass can easily lose its original visibility and “sparkling” appearance.

Problem Glass can also fail to achieve industry standards for light transmission that were met at the time of installation.  This has negative effects on daylighting in a building as well as reducing the well-being and productivity of its occupants.

Problem Glass is likely to be found anywhere one or more of the aggressive trio of MAD is present.  The two biggest enemies of glass are moisture and alkalinity.  Either individually or together, they can etch or dissolve the surface of glass, making it appear dull and sometimes white in appearance.  Some dirt can damage the surface, and further harm can be caused in efforts to remove it.

Moisture can be in its liquid form, such as rainfall, or as a vapour in high humidity areas.  Alkalinity comes from hard tap water, sea water and construction materials such as cement dust and building run-off from concrete, bricks or mortar.

Organic dirt does not normally attack glass but can attach firmly to the surface and be difficult to remove.  For exterior glass, this includes traffic film, bird droppings and tree sap.  For interior glass, organic dirt includes fingermarks and cooking oil vapours.

 Inorganic dirt bonds chemically to glass and is difficult, if not impossible, to remove using conventional cleaning methods.  Inorganic dirt on exterior glass includes sea spray, industrial emissions, metal oxides from railways and construction materials such as cement dust and building run-off.  For interior glass, an example is limescale from hard tap water.

Problem glass is most likely to be found in locations such as:

construction sites

  • sloped glazing – conservatory roofs, rooflights
  • buildings with difficult access for routine washing
  • glazing exposed to run-off from concrete, bricks, mortar, stonework, lead flashing, silicone sealants
  • glazing in polluted areas – city centres, industrial estates, near railways, coastal
  • interior glass – shower enclosures, sand-blasted glass, kitchen splashbacks.

For more than 30 years, Ritec International Limited has developed and supplied innovative and cost-effective solutions for Problem Glass.  These solutions provide either ‘prevention’ for new installations or ‘cure’ for glass already installed – reducing or eliminating the risks of call-backs, delays in construction and complaints.

Intelligent glazing within the home gives glass an eco boost.

14 Oct

 

Glass may have previously be regarded as a rogue in a green world, but a series of hi-tech developments has boosted its eco credentials within the home, suggests leading glass processors, ESG.

Without a doubt, modern architectural movements have seen glass being used to introduce shadow and texture to internal spaces, creating buildings accentuated by light and space. Remove light and any building would present a limited experience that would be entirely nonvisual. Put simply, glass helps to make sense of buildings.

However, with 40% of the UK’s carbon being consumed in maintaining a comfortable interior environment, sustainability and  the energy efficiency glass are going to be of increasing concern, as Scott Sinden, Managing Director of ESG explains:

“Façade and glazing technologies will play an increasingly important role in keeping buildings comfortable without compromising energy performance.

“Hi-tech developments in the form of ‘intelligent glass’ are allowing glass to be seen as more eco-friendly building product.”

Firm in the belief that ‘intelligent glazing’ solutions for the residential market are set to grow in popularity, ESG have secured UK exclusivity to supply ESG Polyvision™, the UK’s largest sized privacy glass on the market. By controlling its optical properties upon application of an electrical current, the glass provides significant solar shading, blocking out a large proportion of UV rays.

Using a minute electrical current, users can immediately switch the ESG Polyvision glass from clear to private (opaque) and vice versa. All ESG Polyvision™ panels involve a PDLC film being encapsulated between 2 or more glass sheets, which can be tinted to add further solar protection. When the electrical supply is switched on, the liquid crystal molecules align and incidental light passes through, making the glass clear.

Increasingly it is being used in the residential market for home improvement or refurbishment projects by used in windows, partition screens, shower screens, doors, projection screens, as well as for security purposes. ESG are also experiencing high demand for ESG Polyvision™ for use as solar shading in Conservatories, making blinds (and their associated cleaning) redundant.

MELT

7 Oct

The consumer’s retail shopping experience could change radically in the coming years following an intriguing new lighting concept developed by SEEDA award-winning artist Esther Rolinson.

‘MELT’ is a work developed with and constructed by Creative Technologist, John Nussey, based on the idea of an architectural or landscape structure that can be reconfigured depending on its location.

Whilst the 1.25 metre square ‘MELT’ prototype is a sculptural work in its own right, the long term objective of the project is to revolutionise the way in which retailers directly influence the mode in which consumers would travel around their store by altering specific pathways of light.

The work has been directed with the goal of achieving specific effects for creating new art works and is expected to heavily influence digitally sensitive works for the retail environment. Designed using digitally responsive glass that can be illuminated with LEDs, at full scale (2.5 metre) ‘MELT’ is capable of manipulating natural and artificial light in response to people within its structure.

Composed of 25 panels of ESG Polyvision™ privacy glass panels, the prototype is held in place by a wooden base and each panel is illuminated externally. Each pane of glass can then be individually-switched from opaque to transparent and as a group they can be programmed to respond in sequence to a light sensor.

The programming concept is an investigation of organic movement patterns that people learn and understand inherently. Whether it’s diminishing ripples, repetitive waves, these are all designed to improve people’s receptiveness in a similar vein to Cellular Automata.

An example could be that the presence of a small number of people in a room stimulates changes of opacity, but if there are too many then the area becomes overpopulated, causing the activity to rapidly diminish, encouraging people to keep circulating in the same way that the automata behaves – such as the flow of a retail store or shopping centre.

This form of experimentation with architectural geometries is capable of altering the experience of internal structure and exterior environment, with the aim of creating a sensory tension between the viewer and the glass/light surface.

Rolinson’s vision has been funded by Arts Council England and sponsored by glass manufacturers Essex Safety Glass (ESG), whom endorse the development of sensitising spaces and structures and currently have exclusive UK distribution rights of Polyvision™ which works using a minute electrical current to switch glass from clear to opaque.

In its unpowered state, the glass panels are opaque but by applying an AC current it is possible to reduce their opacity, making them more transparent and achieving the aim of refining the relationship between viewer and environment.

Rolinson said: “MELT is a catalyst for a continued dialogue focusing on the development of art works and designs that feed into the development of glass and digital technology.

“We are already exploring the sensory and control systems in more depth with support from ESG. The potential for altering a customer’s behaviour in response to their surroundings is quite far-reaching.”

Rolinson participated at the Designing Interactive Systems 2012 Conference workshop on Interactive Lighting Design, contributing examples of the technology and conceptual process used in the development of MELT, with specific interest in their use of art as a medium for pushing technological boundaries.
