Halo® GPS (graphite polystyrene) creates a

thermal break and delivers a long-term R-5 per
nominal inch.
Breathable — walls stay dry and healthy.
When properly installed, products 1/2”+ qualify as a water resistant barrier according to test ASTM E 331 of the International Building Code.

Zero thermal drift. Zero compromise.

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