How does foil insulation facing work?

Posted on 02/15/2023

Foil insulation facing comes in batts or rolls. The batts are precut to fit into standard size of the ductworks or walls. Roll insulation facing is best for ductworks, floors, ceilings, and roofs. All insulation facing is easy to cut with a sharp utility knife or insulation knife. 

The facing has a tab (called a flange) running along each side edge of the insulation. When installing the insulation in wood-frame structures, you fold out the base flange and staple it to the side (or front edge) of the framing to secure the insulation. 

Because the foil insulation facing serves as its own vapor barrier that traps moisture inside a building, it should not be used with additional vapor barriers.

The aluminium foil insulation facing provides three valued insulation solutions: thermal protection, vapor protection, and flame retardancy. These qualities, together, help protect construction from damage over time and help lower overall energy costs.
