Under-Floor Insulation System: Steel Floor Joists

Heat-Ceil fitted to the bottom lip of C Channel Floor Joist with reflective airspace provides an extra insulation layer from reflective still air film.

Heat-Ceil combines Combines the exceptional thermal qualities of EPS and reflective air films

into one easy to use product that requires no special masks or clothing for installation.

Product Description: Heat-Ceil Insulation is a light weight rigid board made of an

SL grade polystyrene core with pure aluminum foil laminated to both sides that reflects 97% of radiant heat, contains fire retardant and is water resistant.
