PURPOSE OF THE CONTINUOUS LOUVRE SYSTEM Purpose of the continuous louvre system The continuous louvre system consists of a support structure to which blades are fitted. The support structure carries the complete louvre assembly and is formed by vertically or horizontal placed mullions fixed by brackets at set distances. Depending on the structure, Renson® offers different mullion types. Blade supports are permanently fixed to the mullions allowing the blades to be clip-locked onto their supports. The method of construction is simple and well tested. Mitred corners, doors, vermin, bird or...

ONLINE LOUVRE SELECTOR Online louvre selector How to select the correct louvre for your application? WEBSITE WWW.RENSON.NET On the website www.renson.net you can find an overview of all louvres including technical drawings, leaflets and product summaries. On this website, you can quickly find the most suitable louvre for your application, thanks to the extensive possibilities of searching, filtering, and calculating. You can also download the results of your selection, contact one of our specialists for additional advice, or find a dealer in your area.

SELECTION CRITERIA This chapter offers you assistance in selecting the ideal Renson® louvre ventilation system. Some definitions well-known in the field of natural ventilation are explained. If the CLS is only used for aesthetic reasons, the theoretical values calculated using the formulas below can still provide an added value. VISUAL FREE AREA(*) = The visual free area is determined by the ratio between the visual distance between two blades (A) and the pitch of the blade (C). PHYSICAL FREE AREA (*) = The physical free area is determined by the ratio between the narrowest opening between...

Flow rate = m3/s Surface area = m2 Air speed = m/s FLOW RATE SURFACE Pressure drop = K x 0,6 x Air speed ² (b) the volume of air passing through the CLS the size of the louvre (front view) the speed of the approaching air at the front of the CLS. (This is the result of a certain volume passing through the CLS.) One can transpose the equations to determine dimensions, air speeds or pressure drop. Link between K-factor and c-coefficient: Selection criteria If two elements are known in this equation, one can calculate the third. Before one can determine the pressure drop one must determine the...

The Renson® louvres were subjected to tests according to EN13030:2001 in Great Britain by BSRIA, a body accredited worldwide. A wall of 1 m², possibly fitted with a stainless steel 304 mesh, was tested in torrential rain with a capacity of 75 litres/hour and a wind speed of 13 m/second. The weather performance class table is drawn up depending on the results obtained, i.e. the quantity of water passing through the louvre. WITHOUT WATER CHANNEL Test of a standard CLS Wind 13 m/s Surface area of louvre 1 m² Transferred water WITH WATER CHANNEL Test of a CLS with mesh and sill Wind 13 m/s...
