Heathrow Airport VCR, UK

Glass on the control tower was cleaned daily in an attempt to maintain good visibility. However, a better, low-maintenance solution was required, and Ritec subsequently renovated and protected the exterior glass with the ClearShield System™.

The results were dramatic. Says a member of Heathrow’s Building Services Department: “Since conversion of the Visual Control Room windows from ordinary glass, regular maintenance using Ritec aftercare products has ensured that, from the original daily window cleaning schedule, the windows now are only cleaned once a week.”

New Bangkok Airport, Thailand

The Second Bangkok International Airport features a modern steel, aluminium and glass architecture covering approximately 100,000m2.

The protection of glass during construction was a high priority for the construction company and specified the application ClearShield® prior to installation. ClearShield® helped to reduce costs and delays on the construction site by protecting the glass from cement, concrete and construction dust.

Farnborough Airport Control Tower, UK

Ritec successfully completed the protection of all glazed areas of the Farnborough Airport Control Tower.


This stunning building whose glazing includes both sandblasted and clear glass is now fully benefiting from the low-maintenance properties of ClearShield®, but most importantly from an increase in visibility and safety which is critical to the operations of the air traffic controllers.


The application was carried out on-site by Ritec’s team of specialist technicians. Some 520m2 of glass was treated.
