When Pilkington first launched what has been the Holy Grail of glassmakers – glass that helps to keep itself clean – scepticism was often the initial response from customers, especially around April. The second reaction, once convinced that this was indeed a serious proposition, is for a keen fascination with the concept, with market research also showing that window cleaning is in the top three of the nation’s most hated chores.
The key element of Pilkington Activ™ self-cleaning glass is a microscopically thin, transparent coating of titanium oxide. Knowledge of the properties of this compound in relationship to glass has been widely available for as long as 20 years. However, it is the on-line application of the coating that has been patented by Pilkington technologists.
Developed in the UK by Pilkington plc at the company’s Research & Development Centre in Lancashire and launched following extensive field and laboratory testing, Pilkington Activ™ will continuously clean the external surfaces of windows by harnessing the two natural elements of ultra violet light and rain. The dual action of Pilkington Activ™ uses a special, permanent hard coating that continuously reacts with ultra violet light from daylight to break down organic deposits of dirt, with a secondary action that causes rain to flow down the glass in an even sheet to wash the deposits away.
Pilkington Activ™ was launched in the UK in September 2000, initially to private home improvement sector. Uptake has been steady, despite the British double glazing market being notoriously conservative, increasing numbers of companies are realising the benefits of offering their customers an intriguing product, and which offers the ultimate low maintenance home improvement.
A number of social landlords have also seen the advantages, in terms of the reduced maintenance benefits of the product, and as a means of satisfying ever more stringent Health & Safety regulations, and potential legal claims. A sheltered housing development for the elderly in Normanby, Cleveland, for example, was installed with Pilkington Activ™ principally as a maintenance solution when the existing timber windows were replaced last year. The three large blocks of three storey maisonettes previously required a costly window-cleaning programme, as the elderly residents were largely unable to carry out the cleaning themselves. The original plan for the refurbishment was to fit tilt-and-turn style windows, but it was decided that even with these the residents would not be able to carry out their own cleaning. Pilkington Activ™ was chosen to resolve the problem, installed in conventional-style frames that were also considerably cheaper to replace.
The Places for People Group (PfP) specified Pilkington Activ for other reasons at Briary Court in Clayton Brook, Preston, a group of flats owned and maintained by the organisation. During a window replacement programme, urgent attention was also required for a conservatory that provided a lounge for the residents. However, such was the design of the structure that it posed a particularly difficult and hazardous cleaning problem, as much of the glass area was completely inaccessible by conventional means. The glass had always presented a problem for cleaning, in terms of cost and potential hazard and PfP decided to use the opportunity to resolve the problem for good by installing self-cleaning glass.
As whole of life cost calculations are now increasingly the norm, then so Pilkington Activ™ is creating a demand in the public sector. In fact it is largely the interest from RSIs that has caused Pilkington to look far more closely at the sector, and the company is now fully focused on the specific needs of local authorities and housing associations.
In addition to residential accommodation, Pilkington has now developed commercial solutions for curtain walling projects and similar applications. Pilkington Activ™ is now fully tested in combination with solar control glass, Pilkington Suncool™, in various colours and offering a range of performance options. Possible applications are now considerably extended to more typical commercial buildings, offering greater potential for reduction of maintenance cost and risk, whilst also simply keeping buildings looking cleaner, for longer.
With homes in Britain now re-appearing from the murk of winter; demanding to be restored to their pristine glory, the prospect of having windows and glass roofs that always look sparkling will be hard for any homeowner to resist. Pilkington, Britain’s biggest glass manufacturer produces a self-cleaning glass that is low-maintenance! In a country that is home improvement crazy, Pilkington Activ™ has provided thousands with the ultimate home solution.
Hearing about Pilkington Activ™ for the first time, the reaction is often one of disbelief, quickly followed by fascination, and the words ‘I want it!’ Now installed in thousands of homes throughout the world, and some very impressive commercial projects, Pilkington Activ™ works by using a special, permanent coating that harnesses ultra violet light and rain to first break down and loosen organic dirt on the glass, for it to then be washed away when the rain comes.
Once it’s installed it takes a few days to ‘charge’ with ultra violet light, following which the coating will begin the steady but inevitable process of, quite literally, breaking down dirt such as sap, bird droppings and the like, where it sits on the glass. It works continuously, helping to keep windows sparkling, even in really tough conditions where an occasional hosing will help to shift heavier soiling.
Although it may be installed anywhere glass is required, Pilkington Activ™ can be especially useful in conservatory and other glass roofs, which are notorious for quickly gathering algae and moss.
Whilst the promised benefits of the product are almost divine, Pilkington Activ™ is in all other ways like ordinary coated glass. It requires no more special attention that you would give to sealed units installed with, for example, Pilkington K Glass™ and therefore offers the ordinary builder every opportunity to install units made using Activ, which are combined with other glasses to offer appropriate performance, such as compliance with Part L. It is available from most, larger sealed unit manufacturers, and especially any Pilkington depot.
Pilkington has also added Pilkington Activ™ Blue to the family. This version has a faint blue tint to it, which acts to reduce the build up of heat in the room and, when combined with other glasses such as low-E, is an excellent choice for conservatory roofs. The most important effect of course, is that it keeps the roof in pristine condition throughout the year. In fact, such a location provides probably the most effective and ideal setting in which to demonstrate the extraordinary properties of this glass.
