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.
