If your ducts are not properly insulated, you’re paying to heat and cool your home without reaping the benefits. Duct insulation helps cut energy costs, creates a more comfortable indoor environment and improves air quality.
Reduced Energy Use
Uninsulated ducts can lose up to 30% of the conditioned air they deliver, leading to higher utility bills and overworking your HVAC system. Insulating your ducts can help keep that conditioned air where it should be, saving money and lowering the stress on your heating and cooling equipment.
Lower Indoor Noise
Insulated ducts reduce the rattling, buzzing and whistling sounds that come from air-generated condensation and expansion in metal ducts. While this isn’t an entirely foolproof way to eliminate these sounds, duct insulation does significantly reduce their volume.
Consistent Temperature Control
Insulation prevents condensation within ducts, keeping the indoor air dry and creating an environment that is less hospitable to mold growth and mildew. This not only improves indoor air quality but also extends the lifespan of your heating and cooling system by reducing overheating and wear.
Duct Insulation Types
Several different types of duct insulation are available, including fiberglass with a foil barrier, polyethylene and rockwool. Each offers a unique set of advantages, depending on your specific needs and project budget. Fiberglass is a cost-effective option that can be installed in most homes. It is resistant to moisture and can withstand high temperatures, making it an effective choice in areas that experience frequent temperature changes. It is also easy to install, simply cutting the insulation and fitting it around the duct. insulation duct
