As a matter of fact our competition has pointed out that the lock is "so..... tight that it cannot be ovalized". This is false of course, but our competition still says it. Spiral is best for&nbsp;maintaining consistent airflow and air pressure. This allows for superior ventilation while reducing the energy costs of heating and cooling.</li><li><strong>Spiral duct installation costs less</strong> than an equivalent rectangular duct design. Parts, labors, packaging, and waste disposal are all reduced for spiral duct.</li><li><strong>Cleaning spiral duct is both easier and costs less</strong> than working with rectangular duct.</li><li><strong>Spiral duct can be more space efficient</strong>, since joints, connectors, and reinforcements on rectangular duct often take up to an extra 3 inches.</li></ol> <p>Are there any reasons left to continue using rectangular duct? Yes. Although spiral duct is by and large the superior choice for medium and high-pressure systems, rectangular duct remains easier to install and may be more efficient in low pressure installations.</p> <p>Just as spiral duct can be more space efficient in some circumstances, the same can be said of rectangular duct in the right circumstances. Spiral is not as wide, but it does take up more height. Of course, this is an issue that can often be addressed by using flat-oval instead of rectangular.</p> <p>Experienced engineers and contractors choose between rectangular and spiral duct based on the specifics of the job and the heating and cooling needs of the building. That said, for years now spiral duct has been gaining in popularity as its potential use in diverse projects is more broadly recognized.</p> <!--EndFragment-->
