It is known, from Meteorological Office Records, that in the United Kingdom, we can expect to "enjoy" 1, 500 hours of bright sunshine every single year. Enjoyable, that is, if you are simply planning to have a break from the office and do your own thing - not so, if you are tied to your desk trying to do a job of work. Taking London (at 51.7° North) as an easily located example, the potential heat gain through vertical glazing is comparable to that experienced in the Middle East. During Spring and Autumn, they are much on a par and during peak summer months, London is exposed to a full 35% additional solar energy than say Jeddah or Riyadh. The challenge is simple but equally daunting when you accept the fact that every 1.4m² of glazing can effectively transmit heat at the same rate as a 1 kW single bar electric fire. The cost of removing that heat in terms of air conditioning can be staggering and the dual problems of direct radiation and glare still persist.

The unique aerofoil blade of the smooth-flow louvre system provides for a pleasing architectural feature which at the same time offers enhanced aerodynamic and weathering performance. Extremely versatile, smooth-flow louvres can be installed into any configuration of wall facade. It also acts as a visually attractive screening system. An important feature of the smooth-flow design is that it allows water to drain completely from both sides of the blade - there is no ridge or receptacle that can allow an unsightly silt pool to form or where potentially lethal bacteria could contaminate the ventilation system. The system is available in 50, 80 and 100mm pitches and may be supplied in continuous form with pre-assembled mullions and metal clips. It is also available in modular and interlocking formats.

Ventilation and solar shading are key to the success of any building envelope and Robertson Thermovent has introduced two ranges of high performance louvres as an essential complement to the integrated facade and curtain walling systems. The new products and associated design services are of the very highest pedigree, coming from a company that has been active in the design and manufacture of ventilation systems since 1908. With the global requirement to achieve drastic reductions of carbon dioxide emissions and the consequent requirement to improve the energy efficiency of all kinds of buildings, there has been a dramatic increase in the demand for natural ventilation products. On this CD-ROM you can find details of the two principal ranges of louvres that are now designed by Robertson Thermovent - the standard and the smooth-flow systems.

The current range of Robertson Thermovent fire ventilation products is the result of over 80 years worldwide experience in the design, manufacture, supply and installation of smoke ventilation systems. Robertson Thermovent is a recognised specialist in the design of smoke ventilation systems and is renowned for its reliable service and technical support. Robertson Thermovent provides a full technical design advisory service with all drawings prepared on CAD systems. This service not only ensures that all smoke ventilation units are designed and tested to meet the requirements laid down in current codes of practice, but that all the latest developments in ventilation are included, where relevant, in a particular project. Robertson Thermovent offers a range of fire ventilation systems, which are engineered by computer selection to determine the effect of the development of fire and the passage of smoke on the configuration of the building. This is essential in order to provide the most appropriate solution to meet individual project requirements. Robertson Thermovent's commitment to a policy of continuous development and rigorous testing of all products ensures their quality and reliability.
