No matter what type of property you own in Kansas, duct insulation and air sealing are key to energy efficiency. Homes, shops, agricultural buildings and even barndominiums all depend on well-sealed ductwork and building envelopes to keep conditioned air where it belongs. Kansas has adopted parts of the 2018 International Energy Conservation Code (IECC), which sets strict rules for both duct insulation and overall air tightness in new construction and major remodels. 

The building envelope is your first line of defense against drafts, hot or cold spots and wasted energy. Spray foam insulation is a top choice for air sealing because it fills every crack, gap and cavity, stopping air leaks in their tracks. In Kansas, passing a blower door test is now standard for new builds, meaning your home or business must have an air change rate below code limits. If there are leaks, inspectors will spot them, leading to costly delays or additional work. 

Ducts running through attics, crawl spaces or other unconditioned areas must be insulated to at least R-8 if they are 3 inches or larger in diameter, and R-6 for smaller ducts. This prevents energy loss and stops condensation, which can damage ducts and lower air quality. Spray foam can also be used to seal duct boots and plenum connections for a tighter, more efficient system. 

Code Requirements and Best Practices 

Kansas code requires that all joints, seams and connections in ductwork be sealed with mastic or approved tape. Simply relying on friction-fit or loose connections is not enough to meet modern standards. After installation, ductwork is often tested for leakage to ensure it is under 4 CFM25 per 100 square feet of conditioned floor area. Failing this test can mean re-sealing, re-testing and additional costs. 

Air sealing is not limited to ductwork. It also applies to walls, floors, ceilings and anywhere pipes, wires or vents penetrate the building shell. Spray foam insulation makes it much easier to meet or exceed these requirements, as it can be applied in hard-to-reach places where traditional insulation leaves gaps. 

For barndominiums and metal buildings, air leaks and poor duct sealing are common problems due to unique framing and open layouts. Our team at Advanced Seal Kansas has the experience to handle these challenges and deliver a solution that passes inspection and saves money over the life of the building.
