High performance ventilation and smoke extraction ducts

The ventilation and smoke extraction ducts made from PROMATECT®-L500 have been tested according to standard EN 13403, which confirms their high performance in terms of cold sealing.

These tests, carried out in an approved laboratory, have shown that the Promat pipes subjected to overpressures or depressions up to 1500 Pa meet the requirements of sealing class D (i.e. at +/- 1500 Pa, a leakage rate of less than 0.42 m3.h-1.m-2).

Class D being the most demanding classification, obtaining this new class attests to the good efficiency of Promat systems. It is also a pledge of professionalism which demonstrates, on the one hand, the expertise that Promat is able to bring to its customers and, on the other hand, its commitment and that of its R&D teams to invest in solutions that meet the most stringent requirements.

Promat ventilation and smoke extraction ducts offer multiple benefits

Designed with PROMATECT®-L500 sheets, the ventilation and smoke extraction ducts are suitable for all constructions of vertical, horizontal ducts, branching on vertical or horizontal duct, offset, against slab or wall, installation of smoke exhaust dampers, on wall or in drag.

PROMATECT®-L500 conduits are able to withstand seismic stresses and vibrations to which certain buildings such as airports, train stations, underground car parks, etc.

The advantages of the duct system in PROMATECT®-L500:

• Ducts tested according to European standards EN 1366-1 and 1366-8,
• Identical assembly for ventilation and smoke extraction ducts,
• Assembly by stapling or screwing,
• Single-layer system without joint cover,
• Unprotected hangers for all ventilation ducts,
• Treatment of joints with PROMACOL®-S or PROMACOL®-K84 / 500,
• Unprotected hangers for all smoke extraction ducts with a section less than 1250 x 1000 mm,
• Section up to 2500 x 1500 mm for ventilation ducts and 2250 x 1125 mm for smoke extraction ducts,
• Classification o↔i for all ventilation ducts (compulsory according to the order of 22 March 2004 amended),
• Classification S (smoke tightness) for all ventilation and smoke extraction ducts,
• Surface roughness factor practically identical to that of steel pipes,
• Can be used in areas with high humidity and outdoors under shelter (areas not subject to wind stress).

The advantages of the PROMATECT®-L500 sheet:

• its lightness: 500 kg / m³ for plates ranging from 20 to 60 mm thick,
• its fire resistance performance (EI30 to 180),
• its CE marking,
• its mechanical resistance,
• its machining: the PROMATECT®-L500 sheet can be worked using conventional tools for wood panels. It is fixed by screwing or stapling,
• its Environmental and Health Declaration Sheet (FDES) available on request and on the INIES database.

It should also be remembered that all Promat products are subject to quality control and their performance is guaranteed by tests in approved independent laboratories.

With unique experience in the field of fire safety, Promat proves once again that the technical innovations of its systems are major markers of difference compared to its competitors. As the French leader in the field of passive fire protection and specialist in high performance insulation, Promat has always had the desire to innovate on a daily basis in order to offer products with unparalleled performance, adapted to the challenges of his clients.
