Halo® 1 in. Exterra® Advanced Rigid Insulation, R-5, 4 ft. x 8 ft. Sheet
Halo® Exterra® is designed to insulate exterior above-grade walls in residential, commercial, and industrial buildings, resulting in energy efficient building enclosures. Halo® Exterra® can also function as the water resistant barrier for the building enclosure (thicknesses of 9/16 in. (14mm) or greater) when the joints of the product are sealed with tape or a liquid applied membrane.
Halo® Exterra® products are rigid foam sheathing insulation boards
made from graphite infused polystyrene (GPS), which offers up
to 18% more thermal resistance than conventional expanded
polystyrene insulation (EPS). Halo® Exterra® is coated with perforated
polypropylene laminates on both sides of the insulation.
- Laminates are reflective or white on one side, and reflective or clear on the other side.
- Laminates are perforated, which allows moisture to diffuse through Halo® Exterra® for thicknesses up to 2 in. (50.8mm).
*Halo® products should be protected from reflective or direct UV
exposure. Always keep stored Halo® products tarped or covered to
protect from weather, and when possible store indoors. Do not use a
clear plastic covering film.*

Until cladding is installed over Halo® Exterra® the following recommendations will help ensure installed products maintain manufactured dimensions.
• Remove or cover the surface that is casting a reflection on installed Halo® products, or shield the affected Halo® products.
• Cover Halo® Exterra® if left exposed for more than 30 days. Faded printing on Halo laminates is normal and will not degrade the products properties.
• Ensure all butt joints are tightly fitted and apply sheathing tape or liquid sealant as soon as possible.
• Immediately tape seal or temporarily cover all joints of inside corners until tape sealant is applied.
