Short answer: Eurovent Certita Certification have a certification programme for rigid and semi-rigid ventilation ductwork systems. Long answer: Eurovent Certita Certification have a certification programme for rigid and semi-rigid ventilation ductwork systems divided into the following sub-programmes: Rigid metallic ductwork systems … Continue reading →
TightVent Europe has published a list of applicable standards for building and ductwork airtightness. The detailed list can be found here.
Continue reading →Short answer: TAAC is the TightVent Airtightness Associations Committee and has the primary goal to bring together national associations and experts on building and ductwork airtightness in order to promote reliable testing and reporting procedures. Long answer: TAAC is the … Continue reading →
France, Belgium (Flemish Region) & the United Kingdom have national databases that gather most of measurements performed by qualified testers in their countries. Other initiatives also exist in Spain, Germany, Czech Republic, Estonia and the US [1], [2]. More information can … Continue reading →
Ductwork airtightness can be defined as the resistance to inward or outward air leakage through the ductwork shell.
Continue reading →The implementation of the EPBD recast puts increasing pressure to achieve better building and ductwork airtightness since for most European climates and countries, good airtightness levels are necessary to achieve nearly zero-energy buildings. This has been shown in a number … Continue reading →
Duct airtightness classes A to D are defined in European Standard EN 12237 for circular ducts and EN 1507 for rectangular ducts. Class A is the leakiest class. A parallel standard to EN12237, EN 1507 and EN 1751 based on … Continue reading →
It depends on the country and context of the measurement. Most EU countries include in their regulations either required or recommended minimum airtightness levels with or without mandatory testing. There are several countries (e.g., United Kingdom, France, Portugal, Denmark, Ireland) … Continue reading →
A method of quantifying how much air leaks into or out of an enclosure. EN 13829 gives a standard test method for buildings. Several standards apply to ductwork systems (see also “How is the ductwork airtightness quantified?“). Building airtightness levels can … Continue reading →
Because air infiltration is uncontrolled, poor envelope airtightness may affect: Indoor air quality: Some rooms may be largely under-ventilated while other are over-ventilated. Energy use: Air leakage may inadequately increase the total ventilation airflow rate; or it may not allow … Continue reading →
