REINFORCEMNETS Where necessary, the ducts will be fitted with special reinforcement bars in order to provide further mechanical strength during operation. Said reinforcements will be calculated using the manufacturer s charts. The maximum deflection of the sides of the duct must not exceed 3% or in any case 30 mm, as laid down in standard UNI EN 13403. FLANGING The individual lengths of ducting will be joined together by means of special invisible flanges with hidden bayonet connections, providing a suitable airtight and mechanical seal to meet the requirements of standard UNI EN 13403. The maximum length of each section of duct will be 4 metres.

Bitumen-based compounds must not be used. It is advisable to apply strengthening gauze around flanging points. Ducts will be built to P3ductal standards and in conformity with standard UNI EN 13403. The ducts will have to be manufactured using accessories with antimicrobial treatment. FLANGING The individual lengths of ducting will be joined together by means of special invisible flanges with hidden bayonet connections, providing a suitable airtight and mechanical seal to meet the requirements of standard UNI EN 13403. The maximum length of each section of duct will be 4 metres. REINFORCEMENTS Where necessary, the ducts will be fitted with special reinforcement bars in order to provide further mechanical strength during operation. Said reinforcements will be calculated using the manufacturer s charts. The maximum deflection of the sides of the duct must not exceed 3% or in any case 30 mm, as laid down in standard UNI EN 13403. SUPPORTS The ducts will have to be supported every 2 meters, lifted from the ground with appropriate fasteners and will have to have a suitable slope in the horizontal portions in order to drain any water. SNOW/WIND LOADS Ducts must be also sized in order to bare the snow/wind loads as stated in the manufacturer s tables. CONSTRUCTION SOLUTIONS Should the ducts pass through the roof, they should be fitted at the end with gooseneck shaped bends in order to prevent water and/or snow from getting in. All external duct openings, like the exhaust outlets, external air intakes etc. will be fitted with special bird grids.

applications in aggressive environments The pre-insulated aluminium HVAC ducts will be produced using environmentally compatible sandwich panels like the PIRAL HD HYDROTEC PANEL COUPLED W/POLYESTER FILM with the following properties: Panel thickness: 20.5 mm; External aluminium: 0.08mm thick, embossed and coupled with corrosion resistant polyester film 13 μm; Internal aluminium: 0.08mm thick, embossed and coupled with corrosion resistant polyester film 13 μm; Initial thermal conductivity: 0.022 W/(m C) at 10 C; Insulating material density: 50-54 kg/m 3 ; Insulating material: polyurethane which has been expanded with the use of only water and not with CFC, HCFC, HFC or HC gasses; Insulation expanding agent: ODP (ozone depletion potential) = 0 and GWP (global warming potential) = 0; % closed cells: > 95% according to ISO 4590; Rigidity class: R 200,000 according to UNI EN 13403; Fire reaction class: 0-1 according to Italian ministerial decree (D.M.) 26/06/84; Fire reaction class: B according to European Standard EN 13501-1; Fire reaction class: approved according to the ISO 9705 standard (Room corner test); Smoke toxicity and opacity: class F1 according to NF F 16-101; Smoke toxicity: FED and FEC < 0.3 according to pren 50399-2-1/1; Smoke toxicity: below 6.7 according to the British Naval Engineering Standard NES 713; Ducts will be built to P3ductal standards and in conformity with the UNI EN 13403 standard. REINFORCEMNETS Where necessary, the ducts will be fitted with special reinforcement bars in order to provide further mechanical strength during operation. Said reinforcements will be calculated using the manufacturer s charts. The maximum deflection of the sides of the duct must not exceed 3% or in any case 30 mm, as laid down in standard UNI EN 13403. FLANGING The individual lengths of ducting will be joined together by means of special invisible flanges with hidden bayonet connections, providing a suitable airtight and mechanical seal to meet the requirements of standard UNI EN 13403. The maximum length of each section of duct will be 4 metres. TURNING VANES & SPLITTERS All rectangular elbows must be fitted with special turning vanes; the large circular elbows will be fitted with splitters in order to meet the requirements of standard UNI EN 1505. SUPPORTS Ducts will be supported by special brackets at intervals which should not exceed 4 metres if the widest side of the duct is less than 1 metre, and at intervals which should not exceed 2 metres if the widest side of the duct is more than 1 metre. Accessories, such as: volume dampers, fire dampers, diffusers, in-duct heating coils etc. will be supported independently so that the ducts do not have to support their weight. INSPECTION Ducts will be fitted with special control points for airflow sensors and doors for inspection and cleaning set at intervals along the ducts as laid down by standard EN 12097 and by the Guidelines published in the Italian Official Gazette dated 3/11/2006 relating to ventilation system maintenance. Doors may be made using the same type of sandwich panel used to produce the ducting, in conjunction with the relevant profiles. Doors will be fitted with seals in order to provide the required airtight seal. Alternatively, P3ductal inspection hatches may be used. AHU CONNECTION Connections between air handling units and ducting will be performed by means of special antivibration joints in order to isolate them from vibrations. Ducts will be supported independently in order to pevent that the weight of the ducts be transferred to the flexible fittings. Moreover, connection with the air handling unit will allow the unit to be uncoupled for system maintenance purposes. Should the antivibration joints be fitted outdoor, they will have to be waterproof.

The ducts will maintain an air seal and mechanical strength according to the prescriptions of the UNI EN 13403 standard. The maximum length of each single piece of duct will be of 1.2 metres. The ducts will have to be fixed using appropriate supports which may be placed up to a maximum distance, between them, of 4 metres. The accessories like the fire dampers, diffusers, etc. will have to be held up autonomously in order for them not to weigh on the ducts.
