Halo® Subterra® is designed to insulate below-grade walls and under slab in residential, commercial, and industrial buildings. The product is manufactured from denser graphite infused expanded polystyrene (GPS), which provides a minimum compressive strength ranging from 16 to 40 PSI (110 to 275 kPa).
Halo® Subterra® is coated with polypropylene laminates on both sides of
the insulation. The laminates are white on one side, and white or clear on
the other side. The denser GPS insulation and polypropylene laminate
makes Subterra® strong and durable against heaving loading and wet
environments, such as backfill and construction traffic. In addition, Halo®
Subterra® acts as a vapor barrier, while providing continuous insulation.
*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 Halo® Subterra® is covered 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® Subterra® 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.
