AWFDA • Acoustic flexible Duct

AWFDA is a thermally and acoustically insulated duct, consisting of a micro-perforated inner duct of the AWFDAL type and a metalized polyester outer jacket. The fibreglass insulation has been developed especially for flexible ducting. A polyester barrier is applied between the fibreglass insulation and the inner duct to avoid the diffusion of insulation particles in the air stream. This flexible duct is easy to install, either on circular or on oval connection parts. As the product does not contain PVC, no toxic vapours are released should fire occur

• The AWFDA flexible ducts are used in ventilation, air conditioning, and air handling systems where high mechanical strength, temperature, fire-resistance, and thermal and sound attenuating qualities are required
