UltraPly TPO XR

UltraPly TPO XR is a fleece-backed thermoplastic polyolefin (TPO) roofing membrane in the Elevate single-ply range. It is a flexible, heat-weldable TPO single-ply membrane produced with polyester weft-inserted reinforcement and an 8-ounce polyester fleece backing.

The membrane is used on low-slope commercial roofs in new roofing, reroofing and recover work. Its technical information sheet is numbered TIS 207 and carries the date June 23, 2026.

The membrane meets or exceeds all requirements of ASTM D 6878.

The sheet is built from three elements: a TPO compound, a polyester weft-inserted reinforcing scrim, and an 8-ounce polyester fleece bonded to the underside. The fleece backing distinguishes UltraPly TPO XR from the plain reinforced UltraPly TPO sheet.

The thickness measurement is taken above the fleece. The coating over the scrim measures 0.017 inch (0.43 mm) on the 45 mil sheet and 0.021 inch (0.53 mm) on the 60 mil sheet, against a performance minimum of 0.015 inch (0.38 mm).

Two product designations are made.

• UltraPly TPO XR 100: 45 mil, 0.045 inch (1.14 mm) thick, with a membrane weight of 0.27 lb/ft² (1.3 kg/m²).
• UltraPly TPO XR 115: 60 mil, 0.060 inch (1.52 mm) thick, with a membrane weight of 0.32 lb/ft² (1.6 kg/m²).

Thickness tolerance is plus or minus 10 percent on both. Both are supplied in 10 ft x 100 ft (3.0 m x 30.5 m) rolls in white, tan and gray.

The item numbers are W56TXRM3099 (XR 100 white), W56TXRLT099 (XR 100 tan HR), W56TXRGM099 (XR 100 gray), W56TXR3M699 (XR 115 white), W56TXRLM699 (XR 115 tan HR) and W56TXRGM699 (XR 115 gray). The tan is designated Tan HR.

Typical values are reported against the ASTM D 6878 performance minimum. Where the two thicknesses differ, the 45 mil value comes first.

• Breaking strength (ASTM D 751, grab method): 340 lbf (1,512 N) and 390 lbf (1,735 N); minimum 220 lbf (979 N).
• Elongation of reinforcement break (D 751 grab method): 25 percent on both; minimum 15 percent.
• Tearing strength (D 751): 120 lbf (534 N) on both; minimum 55 lbf (245 N).
• Brittleness point (D 2137): both thicknesses pass the -40 °F (-40 °C) requirement.
• Ozone resistance (D 1149): pass with no cracks.
• Dynamic puncture resistance (D 5635), machine direction: pass at 60 J and 65 J. Cross direction: pass at 55 J and 65 J.
• Static puncture resistance (D 5602): pass at 25 kg on both.
• Air permeance of the membrane material (E 2178): pass, against a limit of less than 0.004 ft³/ft² (0.02 L/(s·m²)).

After heat aging for 32 weeks (224 days) at 240 °F (116 °C) under ASTM D 573, both thicknesses retain more than 90 percent of breaking strength and elongation at break and more than 60 percent of tearing strength. Weight change is less than 1 percent. Linear dimension change, tested for 6 hours at 158 °F (70 °C) under D 1204, is less than 1 percent. Water absorption under D 471 is less than 3 percent.

Weather resistance under ASTM G 155 is rated above 60,000 kJ/m² against a minimum of 10,800 kJ/m². The test uses a 176 °F (80 °C) black panel, with no cracking or crazing when wrapped around a 3 inch (76.2 mm) mandrel and inspected at 7X magnification.

Cool Roof Rating Council values are given as initial and 3-year aged figures for the white, light tan (HR) and gray sheets.

• White sheet, rated product ID 0008: reflectance 0.80 initial and 0.70 aged, emittance 0.78 and 0.81, SRI 97 and 84.
• Light tan (HR) sheet, rated product ID 0091: reflectance 0.73 and 0.66, emittance 0.90 and 0.91, SRI 90 and 87.
• Gray sheet, rated product ID 0032: reflectance 0.34 and 0.34, emittance 0.89 and 0.88, SRI 37 and 36.

All three share licensed manufacturer ID 0608 and a Production Line classification. White and light tan pass the LEED initial SRI minimum of 85 (97 and 90) and the 3-year aged SRI minimum of 64 (84 and 87). They also meet the Title 24 minimums of 0.63 solar reflectance, 0.75 thermal emittance and 75 SRI, and pass the IgCC 3-year aged SRI minimum of 64. White and light tan are listed as Solar Ready; all three colors are listed as Vegetative Ready. Recycled content is 0 percent post-consumer and 15 percent post-industrial.

Substrates are cleaned, dried and smoothed, with sharp edges, fins, loose material, oil and grease removed. Surface voids wider than ¼ inch (6.3 mm) are filled with an acceptable fill material.

The membrane can be fully adhered with I.S.O. Spray R Insulation Adhesive, Jet Bond Spray Adhesive or hot asphalt. It can be adhered in adhesive beads using XR Stick Adhesive, or in beads or a spatter pattern using Twin Jet. It can also be mechanically attached, or adhered with SEBS Mopping Asphalt (TIS 811) to an approved substrate or modified bitumen sheet.

The sheet is stored away from sources of puncture and physical damage and away from ignition sources, as the membrane burns when exposed to open flame.
