The Energy Star Certified Homes (Version 3.0, Revision 07) HVAC System Quality Installation Rater Checklist states that HVAC ducts, cavities used as ducts, and combustion inlets and outlets may pass perpendicularly through exterior walls but must not be run within these walls unless at least R-6 continuous insulation is provided on the exterior side of the cavity, along with an interior and exterior air barrier where required by the Thermal Enclosure System Rater Checklist. Double wall ducts are designed for noise reduction and thermal insulation, with the walls of the duct being thermally insulated simultaneously. In residential applications, double-wall duct and fittings can reduce radiated noise by 25 dB or more compared to fiberglass duct board and by 30 dB or more compared to insulated flexible duct.
In rooftops across the country, duct systems may be installed outdoors due to application requirements. Double-wall systems require different insulation due to their structure, which includes an insulated inner duct and an outer duct that encases the insulated inner duct. These types of insulated air duct systems can be used to meet various specifications, local codes, and owners’ comfort control needs.
Double wall ducts have the benefit of isolating or semi-isolating the duct liner from the air stream, which is desirable for several reasons, such as keeping the duct liner from the air stream. Placing the HVAC on the outside of a building frees up valuable interior space and lowers building costs. Pro-R duct solutions provide superior thermal performance and durability, improving indoor air quality and energy savings while reducing install times and eliminating costly costs.
📹 Duct Sizing Explained – Why Ducts are undersized sometimes
In this video, Joshua Griffin explains a few theories and misconceptions when it comes to duct sizing. The hope is with more …
What is the difference between single wall and double wall duct?
Double wall spiral ducts offer several benefits for HVAC systems. They reduce the risk of air leakage, allowing the system to heat or cool more effectively. Traditional single-walled ducts lack noise reduction benefits, such as from fans and airflow-related noises. Double wall spiral ducts eliminate the rush of air, eliminating the drawbacks of duct silencers. There is no restriction on airflow, but quieter ductwork remains.
Choosing a double wall spiral duct is a convenient, energy-efficient, and space-efficient alternative to traditional ductwork, making it a valuable choice for any HVAC system installation. Switching to spiral duct work instead of rectangular ductwork can greatly benefit your project.
When to use double wall vent pipe?
Double-wall pipe is recommended for mobile homes due to its longer lifespan and improved draft. It is air-insulated, preventing heat from radiating outside, enhancing the performance of wood stoves. Double-wall pipes have a higher and consistent flue temperature compared to single-wall pipes. Despite being more expensive, double-wall pipes are superior in quality and durability. They have a. 016″ stainless steel inner wall and a. 018″ galvanized outer wall, making them superior to single-wall pipes.
Additionally, double-wall pipes produce less creosote, which can lead to chimney fires if not treated properly. This is because the flue heats up faster and stays hotter for a longer period of time. Therefore, double-wall pipes are a cost-effective solution for improving stove performance.
Can you run HVAC ducts in exterior walls?
The ENERGY STAR Certified Homes (Version 3. 0, Revision 07) HVAC System Quality Installation Rater Checklist states that HVAC ducts, cavities, and combustion inlets can pass through exterior walls but should not be run within them unless R-6 continuous insulation is provided on the exterior side of the cavity, and an interior and exterior air barrier is required. If installing supply ducts within the walls, ensure there is enough space for a duct capable of outputting the necessary air flow. Previously, running ducts inside a wall cavity of an exterior frame wall was common but can create an energy penalty and cause durability issues.
Can you run AC duct outside?
It is possible to run AC ducts on the exterior of a building, but this option is more costly, less energy-efficient, and may potentially cause damage to the building’s exterior, even if it is painted, due to its exposure to the elements.
What is the purpose of the outer wall of double walled piping?
The objective of this process is to prevent environmental releases by containing any leaked fuel within the interstitial space that is created between the pipe’s two walls.
Can you vent through an exterior wall?
A range hood can be ducted to vent to the exterior or recirculate air within the home. The best option is to vent vertically through the roof, as hot air rises. If venting directly above the hood is not possible, vent through a side wall. The cost for installing a new range hood by a contractor is $200 to $500, depending on the complexity of the installation, which does not include parts, ductwork, or electrical work.
When to use a double wall duct?
The CaptiveAire product is optimal for kitchen ventilation applications that require reduced clearance or even zero-inch clearance to combustibles. An email has been dispatched to the team, and should you be interested in representing CaptiveAire and selling their products, you are invited to complete the form, after which you will be contacted in due course.
Where is double wall construction used?
The double wall method represents a traditional approach to the construction of energy-efficient residential buildings. This involves the erection of a primary structural wall (typically the internal wall) and the subsequent construction of a second wall around it, with insulation material placed between the two walls.
Which is better single wall or double wall flue?
Double wall stove pipes have superior insulation with 1/4″ airspace between the inner and outer walls, allowing hotter flue gas temperatures and reducing moisture or soot buildup within the vent. Screws are required for installation. Single wall pipes have 6″ pipes, 7″ pipes, 8″ pipes, and 10″ pipes, with stainless steel inner walls and galvanized outer walls. Follow local, state, and federal regulations for stove heat installation and operation.
What are the advantages of a double wall?
Double-wall construction is a premium wall design that offers structural integrity and exceptional energy performance. It reduces electricity and heat usage, saving homeowners money over time. Double-wall construction also provides excellent air/vapor barrier support and noise reduction due to the layered materials and wall thickness. This creates a consistent and reliable air/vapor barrier, while additional materials and wall thickness prevent noise from traveling through the walls.
Some builders use single-wall construction on their houses, but HiLine Homes ensures premium double-wall construction throughout the house. This premium wall design is a great way to build savings into a home, especially as energy costs continue to rise.
What is double wall pipe used for?
A double wall stove pipe is a type of chimney pipe used to vent wood stoves, fireplaces, or other solid fuel burning appliances. It consists of two layers of metal pipe with insulation to keep the outside cooler. Benefits of using a double wall stove pipe include improved safety, increased efficiency, and reduced clearance requirements. The insulated pipe reduces the risk of chimney fires by keeping the outside cooler. It also improves stove efficiency by keeping exhaust gases hotter, creating a stronger draft.
Double wall stove pipes typically have reduced clearance requirements, allowing them to be installed closer to combustible materials. They are safe and durable when installed and used properly, but regular inspection and cleaning are essential to prevent creosote buildup and ensure proper ventilation.

My new Daikin mini split sydtem has been working well, but there has been times when it is set to 22 C, it can only make it 21 C. The temperature had been -6 C, and it could hold 22C, then a week later when it it was – 6 C again, it could only hold 21 C. The contractor has checked it out, and found things in order. He will be back with his diagonistic device to check out the circuitry.
