FOAMULAR XPS ROOF INSULATION FOR COMMERCIAL BUILDINGS PAGE 13 KEY FEATURES Owens Corning FOAMULAR XPS tapered roofing insulation products provide performance and value in low slope roofing systems and are designed to be used over structural roof decks. THERMAPINK tapered roof insulation provides a thermally efficient, moisture-resistant positive drainage slope for use under single-ply or other types of roofing systems. FOAMULAR tapered roof insulation products are available in three types. Tapered THERMAPINK 25 (ASTM C578 Type IV) insulation is the most commonly used tapered product, but for applications that require higher compressive strengths, tapered FOAMULAR 400 (ASTM C578 Type VI) and tapered FOAMULAR 600 (ASTM Type VII) insulations are available. Owens Corning provides tapered roofing design services with detailed tapered layouts and material quantities to describe how the insulation is to be installed. See your Commercial Area Sales Representative to request tapered roofing services or call 1-800-GET-TECH. See the FOAMULAR Tapered Roof Insulation Product Data Sheet for more details.

Two-Directional Taper System Utilizes tapered panels installed in two directions, accompanied with saddles ("S") between the drains, and half saddles ("HS") between drains and outside walls. The saddles assist in directing the water flow to the drains. 2. Modified Two-Directional Taper System Utilizes tapered panels installed primarily in two directions with saddle ("S") placed between the drains; however, two of the four sides utilize mitered valleys. This system is desirable when a constant thickness of insulation is required at the outside perimeter of the roof. 3. Four-Directional Taper System This system utilizes tapered panels installed in four different directions. Mitered valleys lead to drains. 4. Four-Directional Taper System-Perimeter Drainage Utilizes a four-way taper system directing the water flow to the outside perimeter. This system may be selected when gutters are employed rather than roof drains. Desired drainage is obtained with the creation of hip miters.
