If you want to reduce noise from your pipes and ductwork, you should consider installing acoustical cladding. This lining should be compatible with local building and fire codes and support vibration isolation hangers. To find the best duct lagging solution for your application, contact eNoise Control. Our experts can provide you with expert advice and recommend the right lagging product. In this article, you’ll learn about different types of lagging and what they can do for your pipes and ducts.
Acoustical pipe and duct lagging
Often used to reduce noise transfer in ductwork and piping systems, Acoustical Pipe and Duct Lagging is a mass-loaded vinyl barrier that reduces sound transmission at mid-frequency ranges. Typically furnished in rolls, Acoustical pipe and duct lagging has a Sound Transmission Class (STC) of 1lb/ft. Its superior sound attenuation is measured by independent laboratories using industry standard tests.
To avoid lagging from being damaged by moisture, keep it in a cool, dry place away from heat and direct sunlight. If you use it indoors, make sure you maintain the desired humidity levels while installing it. You can read about the installation and maintenance requirements of Acoustical Pipe and Duct Lagging. The manufacturer’s data sheet contains important safety information regarding acoustic lagging.
INS Acoustical Pipe Lag Type FL is an excellent choice for commercial applications, where fibre erosion is an issue. This product offers a high level of sound insulation, is easy to apply, and minimises volumes. This product is fire and temperature resistant, so it is ideal for industrial applications. It is also available in custom sized sizes to meet a variety of needs. Its versatility allows it to meet building codes and meet all the specifications of the project.
Using an ASTM-E90 sound transmission test method, mechanical engineers can measure the acoustic transmission of a building element. Based on the results, they can determine STC (sound transmission class), which is a numerical rating of the material’s ability to reduce sound transmission. The higher the STC rating, the better. These tests are conducted at a laboratory and then in the field to ensure that the product is effective in minimizing sound transmission.
Mineral Fibre industrial lagging
Mineral Fibre industrial duct lagging is made of natural minerals, such as quartz and clay. This material is chemically inert and rot and vermin-proof. In addition to being a natural product, Mineral Fibre is also a cost-effective alternative to asbestos or other materials used in ducting. Here are some of its benefits. Read on to learn more about its various uses.
There are two main types of mineral wool: stone wool and insulation glass. Both types of these materials have the same properties and are non-combustible. Stone wool is composed of 98% inorganic rock and 2% organic material. The organic content is usually an adhesive or thermosetting resin binder. The mineral wool is resistant to moisture, fire, and abrasion. It can also be used for duct insulation and pipe covering.
Mineral fibres are highly effective in insulating a variety of applications. For example, micaceous magnesia alumina-silicate is a lightweight concrete slab or loose filler. ULTIMATE(tm) insulation has excellent fire resistance and is 50 percent lighter than traditional stone wool insulation. It also has excellent sound absorption and air-flow resistivity values. Mineral wools are often used as blankets or loose-fill insulation.
Another benefit of mineral wool is its fireproof properties. The mineral wool is the same material used to fireproof steel members in commercial buildings. Because it is extremely resilient to fire, it will last longer during a fire, allowing occupants more time to escape. It also gives firefighters a much safer window to enter a burning house. If you are a professional installer, it’s best to wear a quality dust mask and cover the mineral wool material with drywall or other coatings.
AudioSeal(r)
AudioSeal(r) Duct and Pipe Lagging is a mass-loaded vinyl noise barrier with a scrim foil face. The flexible vinyl noise barrier is available in either one-inch or two-inch thickness and can be applied to noisy pipes and ducts. It is ideal for blocking noise transmission through walls and is compatible with fiberglass insulation. Its elasticity and flexibility make it a convenient and effective solution for a variety of applications.
AudioSeal(r) duct and pipe wrap is a Class 1 fire-rated sound-absorbing material that provides thermal insulation and is easy to install. It comes in 54-inch wide x 30-foot lengths and is easy to cut and install using matching lag tape. The vinyl material is made of a one-pound per square foot mass loaded barrier that is laminated to a scrim-faced, quilted fiberglass decoupler.
AudioSeal(r) DL-10-LAG
The AudioSeal DL-10-LA-G mass-loaded vinyl duct lagging offers a complete solution for reducing radiated noise in HVAC ducted systems. It is easy to cut and install, and combines the benefits of fiberglass insulation with the durability of mass-loaded vinyl duct lagging. It is suitable for many applications, including the enclosure of noisy pipes, valves, and fan housings.
HH Lagging
The application of HH Lagging in ductwork is a common solution for reducing noise and vibration in pipes and ductwork. It comprises a 2.5 mm polymeric barrier and a 25mm glass fiber quilt with an inner spacer layer and reinforced aluminum foil on the outer face. The HH Lagging has an acoustic rating of A1 and is considered non-combustible. Its flame resistance is determined by BS EN 13501-1 and its fire safety performance is BS EN 5852 part 1.
It is time-consuming to install HH Lagging in ducts because it requires separate scaffolding and contractors for the installation of insulation. In addition, the lagging supports hamper the installation process, which results in an additional cost. To overcome these challenges, it is possible to install pre-insulated panel on medium-temperature heating ducts. This method is also cheaper than HH Lagging, since it is easier to apply.
