Durable, silent and air-tight ventilation system
CLIMAVER® A2 Plus self-supporting duct system for the distribution of air in ventilation, heating and cooling systems, especially where acoustic and interior cleaning and fire safety requirements are high.
Characteristics
- High-density glass wool Climaver® A2 PLUS panel is covered with reinforced alu foil inside and outside to provide vapor barrier.
- Manufactured from inorganic chemically biosoluble materials and do not include anything that would have effect on corrosion and shall not facilitate microbial growth.
- Technical characteristics in compliance with applicable regulations.This section features all the technical characteristics required for references standards: EN 14303, EN 13403, EN ISO 354,EN 13501-1,EN 15715 , EN 12667, EN 12939, EN 12086, EN 1604 , EN 12237

(*)Acoustic attenuation (DL, in dB/m) estimated via: DL=1.05·αp1.4 ·P/S (αp: sound absorption coefficient, P and S: perimeter and duct section). For the sound power of a ventilator with a 20,000 m3/h flow, load loss 15 mm.w.g.
Pressure loss
For normal HVAC systems air speed pressure drops are similar to metal ducts , ASHRAE charts for metal ducts can be used
Other information
- High mechanical strength: duct is durable and can stand static pressure without reinforcemets up to 800Pa
- The interior facing has a high mechanical resistance, meaning that the duct can be cleaned using the most aggressive methods, such as, for example, brushing
- Textile frame: total sound wave permeability and absence of perforations susceptible to the accumulation of dirt
- Marking of SDM guide lines: points of reference for the construction of duct layouts using the Straight Duct Method, or SDM

Working conditions
- Application as EN 13403
- Maximum temperature of circulating air: 90°C
- Maximum external air temperature 60ºC
- Maximum Static pressure: 800 Pa (80 mm w.g.)
- Maximum air speed : 18 m/s
Assembly
Although there are other assembly methods, the recommended method is the “Straight Duct Method”, SDM. This method is based in the use of a straight duct as the basis to obtain duct fittings, and, therefore, the ductwork. The Straight Duct Method uses two types of accessories:- CLIMAVER tools: CLIMAVER MM, used to groove the panel so that it can be folded into the duct section, and CLIMAVER SDM, used to cut the straight duct and obtain the pieces that will be used to make duct fittings.
- CLIMAVER Glue and CLIMAVER Tape: These are used to seal joints when making duct fittings. CLIMAVER Glue has been specially developed to glue glass wool. CLIMAVER tape is made of pure aluminium, 50μm thick and 65 mm wide.
