Division 7 Ebook Page 339 Under Slab Insulation Overview

Section Overview Under Concrete Slab Insulated Floor Systems Under Concrete Slab Insulation Industrial and low temperature concrete slab floors are insulated to save energy and reduce the cost of building operation. Well insulated floor slabs are particularly important in the operation of low temperature and cold storage buildings. In addition to the energy cost savings associated with well insulated slabs, insulation and under floor heating systems provide protection for floors against damaging frost heave. The insulation also must be structurally capable of supporting the high rack storage and/or forklift traffic loads that are common on industrial and low temperature floor slabs. FOAMULAR 400/600/1000 Under Slab Insulation FOAMULAR extruded polystyrene (XPS) insulation is perfect for under slab environments. It is closed cell, chemically hydrophobic, and homogenous in structure (unlike EPS, bead board). Those characteristics give FOAMULAR XPS insulation superior water resistance, enabling it to maintain its R-value of 5 per inch of thickness and structural properties even in a moist or wet under slab environment. FOAMULAR XPS insulation is available in high compressive strengths of 40, 60 and 100 psi for use under high load and high traffic concrete slabs in industrial and low temperature storage buildings. Other engineering properties such as recommended load limits and foundation modulus are available to help select the correct strength of product for the situation. FOAMULAR LT30/LT40 Under Slab Insulation Particularly well suited for the typical load carrying demands for insulation under low temperature floor slabs, FOAMULAR LT30 and LT40 insulation have compressive strengths of 30 and 40 psi respectively. Both also have the same thermal resistance of R-5 per inch of thickness as other FOAMULAR products. Sustainability Owens Corning is committed to driving sustainability through greening our operations, greening our products and accelerating energy efficiency in the built environment. Owens Corning FOAMULAR XPS products, are GREENGUARD Indoor Air Quality Certified and GREENGUARD Children and Schools Certified SM . FOAMULAR XPS is also third party certified, to contain a minimum 20 percent recycled polystyrene content and is produced with a zero ozone depletion blowing agent formulation. FOAMULAR XPS insulation products contribute to achieving credits in multiple LEED categories including energy efficiency and recycled material content and carry a lifetime limited warranty 1 on all ASTM C578 physical properties for true long lasting value.
