The role of cladding sheets in duct insulation: How they can help reduce energy loss

Air ducts are one of the primary ways that heated or cooled air moves throughout our homes and buildings. However, uncovered ductwork allows precious energy to escape before it reaches its destination. This wasted energy means higher utility bills and an HVAC system that must work harder than necessary. Installing cladding sheets from trusted suppliers is an effective solution.

 

How energy is lost through ductwork

A considerable quantity of energy is lost by conduction, radiation, and air leakage in uninsulated ducts. Heat radiates out of the ducting and passes through the metal with ease. Conditioned air can also escape prior to delivery through gaps and seams where duct parts join. This can result in the waste of more than 30% of the energy utilized to heat or cool a home. The HVAC system needs to work harder to maintain the optimum temperature for every degree lost. 

 

The benefits of cladding sheet insulation

Cladding sheets, also known as duct wrap or duct insulation, provide an ultra-effective barrier to prevent energy loss when wrapped around ductwork. Two layers of reinforced foil with a bubble design trap radiant heat within hollow voids, resisting conduction. The material is also tear and puncture-resistant to protect against insulation damage over time. Properly installed cladding sheets can reduce heat loss through ducts by up to 90%, lowering energy bills significantly. Less wasted energy means the HVAC unit runs less often and uses fuel more efficiently.

 

Choosing the right cladding sheets for your needs

There are a few different types of cladding sheets suited for various applications and environments. Fiberglass insulation is a budget-friendly option but not as durable long-term compared to foil-faced duct wrap. Polyethylene-reinforced foil cladding sheets offer excellent resistance to moisture and have a Class 1 flame-spread rating for use in attics.

For underground ductwork or high-humidity areas, reinforced aluminum cladding sheets that won’t absorb moisture are recommended. Be sure to select an R-value rating suitable for your climate needs – higher R-values block more heat transfer.

 

Professional installation for maximum effectiveness

While a homeowner can wrap their own ductwork, professional installation is highly recommended to achieve the full insulation benefits of cladding sheets. Proper securing methods like stapling, taping, or wire-tying ensure a tight, wrinkle-free fit that won’t degrade over time. Any gaps or loose edges allow conditioned air to escape before reaching rooms.

Ask an HVAC contractor to inspect your existing duct system, measure for the correct cladding sheet size, and install it with integrated seams and joints. This will maximize energy savings from reduced loss through the ductwork.

Installing cladding sheets around your HVAC ductwork is a smart, affordable way to save significant energy costs over the long run. Proper installation by an HVAC pro like Delta Duct ensures a sealed envelope that prevents up to 90% of heated or cooled air from escaping undelivered. With lower utility bills and less work for the HVAC unit, cladding sheets easily pay for themselves over their lifespan.
