Halo Exterra products are rigid foam sheathing insulation made from BASF Neopor® 5300 Plus GPS (expanded polystyrene containing graphite), which offers up to 18% more R-value than conventional EPS. Halo Exterra is coated with a reflective and clear laminate that is perforated to maintain breathability.

Halo Exterra provides a breathable, waterresistive barrier for building envelopes, while providing continous insulation. Halo Exterra is breathable up to 2” thick, and acts as a water-resistive barrier (does not require building wrap) for thicknesses of 9/16” or greater.

• Perfectly Designed For Exterior Applications
• Exterra offers a high-performance GPS core that is laminated on both sides with a precision-perforated film.
