Available in a 500mm wide pre-cut version for insertion between joists or 1000mm wide, the Kingspan AIR-CELL Permifloor has been manufactured using Kingspan’s unique, patented design. This involves a closed-cell, cross-linked foam structure that is sandwiched between highly reflective foil surfaces that have been perforated.

As with our other products, these tiny holes allow water and vapour to permeate, preventing the dangerous collection of moisture that can sometimes occur under the flooring when traditional underfloor insulation systems are used.
