Colder air circulating through the hottest areas of your home can cause condensation to build up on spiral duct accessories. This moisture can cause mold and mildew to grow unless you properly insulate it. Most HVAC ducts need to be insulated. At Spiral Pipe of Texas, our home area encompasses regions with high temperature and humidity fluctuations. It's no wonder that we've been at the forefront of developing and implementing products for insulating ducts.
Factory-insulated duct products reduce labor in the field, in addition to providing uniformity and product characteristics that are not obtained with thermal wrapping. Duct insulation is also essential to reduce air conditioning system noise. Here are some of the product options for round insulated ducts that are available at Spiral Pipe of Texas:In general, the double-walled spiral duct is relatively better compared to the rectangular-walled duct, making it ideal for most air treatment systems. For the suspension and support, the weight of the dust collecting duct is calculated as the weight of the duct itself plus the weight of the sawdust that fills half of the duct.
More duct sealant will be needed. Even if you don't check the duct to verify that you haven't met energy standards, you'll have to build the duct to seal class A. Maintenance: It's also easier to repair and maintain a double-walled spiral duct than a rectangular one. The only mechanical joints that do not have to be sealed according to this standard are the spiral joints of spiral ducts. The result in this case is the reduction of the drum effect caused by the vibration of the duct compared to a rectangular wall duct.
The Biyang double-walled spiral duct is made of a large spiral duct on the outside, an insulation in the middle, and a small spiral duct on the inside. Double-wall systems require completely different insulation because they are structured differently, with an insulated inner duct and an outer duct lining the insulated inner duct. The essence of a double-walled insulating spiral duct is to ensure that it constantly maintains the desired temperature of the air circulating through the duct system. ASHRAE manuals and design guides recommend using oval, round, flat ducts instead of rectangular ones. The Johns Manville One-inch Spiracoustic Plus VVSD is the only pre-perforated duct liner specifically designed to fit ducts with diameters between 6 and 8 inches.
This allows contractors to ensure that the Spiracoustic Plus fits exactly the size of the duct they insulate and helps improve the installation process and quality in these smaller ducts.HVAC Insulation Duct Board Duct Lining External Duct Insulation Flexible Duct Insulation Accessories Source: Insulation Intel. The inner metal housing protects against insulation erosion, maintains a uniform cross-section of the ducts and facilitates the cleaning of the ducts. You can avoid obstructions in the air flow, similar to how you do with traditional connections in air conditioning ducts with screws and glue, but to get those nice rolled ends, you have to use a duct with a longitudinal seam. Most leaks in all ducts occur at joints, and you'll need to make about twice as many joints with a rectangular duct (56 standard lengths from a TDC coil line) than with a spiral duct (typically supplied in lengths from 10 feet to 0 feet).Insulating your home's spiral ducts is essential for maintaining comfortable temperatures throughout your home while reducing energy costs.
With so many options available for insulating your home's ducts, it's important to understand which type is best suited for your needs.
