HVAC Duct Insulation
Enhances Thermal Performance by Reflecting 95 Percent of Radiant Heat.
Astro-Safe is made from lofted non-woven polyester laminated with either one or two reflective metalized surfaces. When wrapped around the exterior of HVAC ducts, it enhances thermal performance by reflecting as much as 94 percent of radiant heat. Its top fire rating makes ASTRO-SAFE one of the safest forms of duct insulation on the market.

Astro-Safe Installation Instructions
- Position 1" foam spacers along the corners of the duct. The additional airspace will increase resistance to heat loss or gain.
- Begin wrapping ASTRO-SAFE around the duct starting at the midway point of the right side of the duct. Proceed counter clockwise.
- Position a 1" foam spacer in the center of the duct on top of the first layer of insulation. Once at the starting point, extend ASTRO-SAFE to create a second layer along the top of the duct. Extend this second layer over the foam spacer to the midway point of the left side of the duct.
- Tape all seams and butt-joints using reflective tape. Repeat the above steps for the entire length of the duct, until its surface is fully enclosed.
