Formaldehyde-free™ Fiberglass Duct Wrap
Microlite® FSK Formaldehyde-free™ duct wrap insulation is a lightweight, highly resilient, blanket-type thermal insulation. The insulation blanket is manufactured from rotary-process fiberglass bonded with a formaldehyde-free resin.
Microlite® Formaldehyde-free™ insulation is available in a variety of densities, thicknesses and roll lengths. It is supplied with an FSK (foil-scrim-kraft) vapor barrier facing to meet installed performance requirements, with a 2" (51 mm) stapling tab. Microlite® FSK is 48" (1219 mm) wide.
Microlite® insulation is recommended as thermal insulation for the exterior of HVAC systems or other spaces or surfaces where temperature control is required.
Microlite® FSK duct wrap is not recommended for use on duct systems in service at temperatures above 250°F (121°C). It should not be used in weather-exposed applications without proper protection.
Microlite® FSK duct wrap should be kept clean and dry during storage, transport, installation, and system operation.
Microlite® FSK Formaldehyde-free™ duct wrap offers superior thermal performance and condensation control in a lightweight, blanket-type insulation with an FSK facing. It is recommended for HVAC system exteriors or surfaces where design parameters prohibit the use of liner or board. Installing contractors prefer Microlite's binder for many reasons, including improved handling, easier cutting and less dust.
