Zero thermal drift. Zero compromise

  1. GPS (graphite polystyrene) provides R-5 per nominal inch*
  2. GPS provides a permanent long-term R-value and won’t deteriorate over time like XPS and ISO.
  3. GPS delivers greater R-values at lower outside temperatures.
  4. Minimizes the energy loss from thermal bridging
  5. Light yet durable — perfect for today’s demanding jobsites.
  6. Superior indoor air quality due to Halo®’s clean steam-fused GPS core.
  7. GPS is 100% recyclable and ozone layer-friendly — no CFCs or HCFCs.
