In Slab Duct

In Slab Ducts

An in-slab duct is a rectangular spiral seamed duct entrenched in high-rise buildings' structural concrete floors. The right in-slab duct and ventilation system has a 3-hour fire rating on all encased components. It must have also passed extensive testing to give trouble-free installation and service.

The primary use of in-slab ducts is to drain air from bathroom fans, hoods, and clothes dryers.

Benefits of In Slab Ducts

In-slab ducts consist of a full range of terminations, couplers and fittings, although you could also fabricate custom fittings for specific applications.

Slab ducts and ventilation systems are used in various structures because of their reliability. They come in handy in these situations because of the flexibility of their design and layouts. The best ductwork manufacturers use automated manufacturing equipment in producing them because they guarantee quality and ease of installation.

The average HVAC slab duct is manufactured in 10-foot lengths. This significantly reduces labour costs and makes it easier for the fitters to do their jobs easily and build runs effectively. Once each run is ready, the concrete is poured over the finished design so that the next level of the high-rise can be built. With the efficiency of in-slab duct, you can save 1 floor for every 10 floors on a high-rise building.

One other reason why in-slab ducts come in handy in buildings. It can be used because they eliminate the expensive use of dropped ceilings to conceal pipes and elbows used in older fabrication methods. Plus, they are durable and proven to resist deformation even in situations where they have to handle loads as heavy as 440 lbs. of aggregate.

In sum, in-slab ducts provide the following benefits:

  • Easy shipment;
  • Aesthetically Pleasing on High-Rise Buildings

Summarily, it’s vital to understand that in-slab, ducts can be the difference between increased heating and cooling costs and the overall comfort. The secret is that they have to be handled by professionals like us.
