LIT-1004-X-Grade-PIS-091814 ® PRODUCT DESCRIPTION ThermalStar® X-Grade® is below grade rigid insulation with a distinctive trademarked orange color. Several grades are available depending on the application. Standard features include: •Manufactured with EPSx® technology, providing integrated termiticide & wax for long term protection •Non-diminishing, warranted R-value •Excellent moisture resistance •High compressive strength •Available scored for snapping to into 16” or 24” wide panels •Lightweight yet industrial strength •Closed-cell construction •Recyclable TYPICAL USES ThermalStar® X-Grade® has been designed specifi- cally for use below grade. Other rigid insulation is re- stricted for use at or below grade in many areas by code because termites can tunnel through foam plastic to the rest of the house, and thus remain hidden from pest control inspectors. The combination of a wax matrix, 2nd generation EPA registered termiticide, and polystyrene assures long term performance below grade in compliance with all building codes. Lower grades are suitable for vertical use, higher grades for weight bearing applications.

The higher the R- value, the greater the insulating power. INSTALLATION AND HANDLING ThermalStar X-Grade can be handled much the same as wood sheathing, using similar tools or simple utility knives to cut, score, shape, or other- wise customize panels to fit the application. Specific installation instructions for below grade applications can be accessed from www.atlaseps.com. WARRANTY ThermalStar X-Grade Insulation is backed by a limited lifetime warranty for physical and thermal performance, as well as for termite resistance. Rigid Insulation X-Grade® Rigid Insulation ® CHEMICAL & PHYSICAL PROPERTIES Physical properties of various grades can be found in Table 1, while chemical resistance is listed in Table 2. MOLD RESISTANCE ThermalStar X-Grade insulation has been tested against 4 week exposure to various mold and fungi via ASTM G21, D3273, and C1338 with no growth of spores on the product. X-Grade insulation provides no nutritive value for mold. However, construction prac- tices greatly impact mold growth, and fungi have been known to even grow on glass. FREEZE/ THAW EXPOSURE ThermalStar X-Grade insulation has been tested via ASTM C1512 Moisture & Temperature Cycling for Insulation with no loss of physical or thermal performance. This test places the product between a cold chamber and a high humidity chamber with tem- perature cycling, measuring the effect on the insulation as natural moisture drive occurs. SAFETY MSDS for this product available at www.atlaseps.com. Dust generated from sanding or cutting ThermalStar X-Grade Insulation should be avoided using a dust mask as with other building materials. X-Grade insulation is combustible and the product should be protected from ignition sources such as open flames or welder’s torch. Applica- tions not specifically listed in UL ER16529.1 require permanent sepa- ration of X-Grade insulation from the interior of the building by a ther- mal barrier such as drywall or concrete for fire safety. ENVIRONMENTAL ThermalStar X-Grade Insulation uses air in the insulating cells, emitting no gasses. The ppm levels of termiticide incorporated into the polysty- rene do not present leaching concerns under typical applications. X- Grade insulation is readily accepted for recycle.
