Reflective Insulaltion from Atro-Foil International

A HIGH-STRENGTH Insulating Moisture Barrier
for Use Below Heated Concrete Floors

Absolute Moisture Barrier
Keeps heat-robbing ground moisture away from the concrete.

Reduces Downward Heat Loss By Over 50%
Exceeds the requirements of most HVAC load calculation programs.

Super-Strong 338 PSI Puncture Resistance
Will support over 6" of concrete plus floor loads indefinitely.

Total of Over 16 mil Extruded Polyethylene Film
Withstands rough handling by installers and finishers.

Air-Encapsulating Vacuum Formed Bubbles
Results in a structure that will not delaminate.

Laminated With 99% Pure Polished Aluminum
Adds a reflective benefit to the intrinsic R-value.

PET Coating Strengthens and Protects Foil Against Chemical Erosion
Tuff-Stuff can be laid with the foil side up or down, whichever is most convenient.
