Outdoor duct insulation specification

The outside layer of foil is made of heavier foil. Microlite Vinyl duct wrap is a thermal insulation made from flame attenuated fiberglass fibers laminated onto a white vinyl facing. It is made with a phenolic binder and laminated onto a white, vinyl facing.

What is duct insulation? The product provides an R-6. There is a choice of three spacer configurations that create the required air space. Fibrous glass duct wrap insulation is designed for application to the exteriors of commercial and residential sheet metal heating, ventilating, and air-conditioning ducts and plenums operating at temperatures between 40˚F (4˚C) and 250˚F (121˚C ). Must have a minimum performance temperature rating of 165° (per UL 181A-type test) and a minimum tensile strength rating of pounds.

Flexible duct between the cable tie and end of metal or PVC duct will be screwed. PVC-to-PVC materials will be fastened with approved PVC cement. Thermaduct is available in insulated values between R-and R-and offers extremely low air leakage. Option (all seams tape maintain airspace): Wrap the insulation around spacers, R-6. Option (all seams tape maintain airspace): Wrap insulation around spacer times, R-8.

The contractor shall include for the manufacture, fabrication, supply, delivery and installation of materials necessary for the ductwork systems described in this specification.

Duct insulation : Ventilation supply ducts installed outside of the thermal envelope Envelope The separation between the interior and exterior environments of a building that includes a combination of air and thermal barrier will be insulated to a minimum of R-or equivalent to local codes. Use this Master Flow sq. Fiberglass Duct Wrap Insulation to reduce condensation in, absorb noise from and improve the air temperature efficiency of your duct system. Duct liner pins that mechanically attach, wel or adhere to the sheet metal, and have a shank length that is equal the thickness of the insulation must be used.

After installation, and prior to occupancy, blow out duct system to remove any cutting scraps or foreign material remaining in the duct. The Code requires that insulation materials for air ductsbe of either non‐combustible construction or have a limited flame spread rating and smoke developed classification. The Code expressly forbids the use of foamed plastic insulation on and in interior and exterior air ducts. The most effective type of insulation is one that is thick, dense, and allowed to take up space, giving it more room to create a barrier between the ducts and the outside air. It will apply to either factory or field jacketing.

CW” products have a pressure sensitive adhesive, covered with a release liner, over their entire inside surface. NA” products have no adhesive. Thermaduct is a patented pre-engineered duct system that incorporates the duct , insulation and cladding all in one high performance product.

While other manufacturers use tapes, adhesives and screws, which experience degradation over time, Thermaduct uses a seamless heat formed corner or chemical welded seam to ensure impervious water integrity. Withstands Harsh Weather Conditions. Outdoor Duct Made Easy.
