LeakBarrier® PS200^HT Ice and Water Armor

LeakBarrier PS200^HT Ice and Water Armor is a premium, SBS modified, glass fiber reinforced, self adhesive modified bituminous roofing underlayment for use under tile, metal, slate and asphalt shingles. PS200^HT is manufactured with a specially engineered Hybrid Polymer System formulation that allows the underlayment to withstand high temperatures (resistant up to 260° F). PS200^HT is surfaced with a polyester fabric on the upper layer to provide a non-abrasive surface that also offers excellent walkability.

PS200^HT Case Studies

Usage

LeakBarrier PS200^HT Ice and Water Armor helps to protect a building's deck or internal structure against leaks caused by ice and water damming and wind-driven rain. It is highly effective in critical roofing areas such as valleys, ridges, coping joints, chimneys, vents, dormers, skylights and low-slope sections.

Features and Benefits

• New polyester fabric surface allows for better walkability and cooler surface temperatures.

• Specifically designed for the demands of metal and tile roofing systems, with high temperature stability of 260 °F, and polyester fabric surface for maximum walkability. Non-skid surface also helps prevent tile from sliding off the roof.

• Split-back release film peels off for easy installation and handling.

• 120 day exposure limitation allows for long term dry in.

• Adheres directly to concrete, plywood, wood composition board and gypsum sheathing decks.

• Self-sealing around nails preventing moisture penetration.

• Product available for multi climates.

• Functions as a vapor barrier for commercial roofing applications.

• Meets ASTM D 1970

• Miami Dade County Approval NOA No. 08-0804.10

• ICC-ES ESR-2116

• Florida Building Code FL 10450-R1

• UL Prepared Roofing File No. 16744

Storage

• PS200^HT rolls must be stored indoors, in a dry location.

• Rolls must be stored on end only. Do not store in a leaning position.

• The rolls must be protected from the elements. Do not expose rolls to direct sunlight.

• Store rolls at room temperature. Prolonged exposure to elevated temperatures may reduce the adhesive characteristics of the membrane.

General Precautions

• Install PS200^HT only when material interface temperatures (air, deck, material) are 40 °F and rising.

• Do not install when any form of moisture such as water, ice, snow, dew, rain, etc. is present.

• Ensure roof has positive drainage prior to installation.

• Proper ventilation is critical. When applying over the entire roof deck, the roofing system must provide sufficient ventilation, including both ridge and soffit venting.

• A full, irreversible adhesion is achieved when the underlayment goes through a complete heat cycle. Do not attempt to remove the underlayment immediately after adhesion to the substrate.

• Use of a hand-held "hot air gun" might help in enhancing adhesion during application of underlayment in cooler weather.

• (Applicable for the State of Florida only) - All tiles shall be staged (two tile perpendicular to slope, four tiles on top parallel to slope), not to exceed 6-high. When installing flat tiles and lugged tiles above 6:12 roof pitch, PS200^HT shall be installed behind a nominal 1" x 2" horizontal batten.

• PS200^HT must be covered with a finished roof covering within the specified exposure time of the product. Refer to section on Features and Benefits for exposure times.

Surface Preparation

• Surface must be clean, dry, and without voids, that may interfere with adhesion.

• For re-roofing, all old roofing and other loose materials must be removed prior to installation.

• Acceptable substrates for adhesion of LeakBarrier membranes can be found on the Tarco website

• For best results, surface may be primed with an ASTM D 41 Primer prior to installation of PS200^HT. When primer is used, ensure the primer is fully dry prior to application of PS200^HT.

Application

• Cut the PS200^HT roll to suitable, manageable lengths before installation.

• Place a full width piece of the pre-cut PS200^HT underlayment on the substrate, parallel to the eave (low) edge of the roof.

• Align PS200^HT so that it is parallel with the edge of the eave and extend over the eave and rake approximately 3/8".

• Place the side lap on the up side of the roof, fold back the sheet, and remove the exposed release film, taking care not to displace the sheet.

• Working from the center out, roll the sheet onto the substrate, taking care to avoid wrinkles and ridges. PS200^HT must be set straight. Repeat this process for the remaining half of the sheet.

• Apply a 1/16" thick layer of asphalt plastic cement over the eave and rake metal drip edges extending 2" to 3" onto the deck surface where the roll will intersect.

• Apply full roll width, a 1/16" thick layer of asphalt plastic cement to the surface of the first course in the 6" end lap area before adhering the next course.

• Apply the next eave course in the same manner overlapping the first course at the end lap by 6".

• Remove release film covering the selvage, if present, prior to application of the next sheet.

• Lap the succeeding course over the lap area just to the fabric edge of the preceding course.

• Roll the side lap and end lap areas with a weighted roller.

• Apply succeeding courses in like manner, as in steps above.

• Stagger the end laps a minimum 3' from the preceding course.

• Install capped or tin tagged nails 6 inches on center in the middle of the selvage edge (side lap) or fasten according to applicable building codes.

• At the T-Joint (where an end lap and next overlapping course intersect), apply a bead of roofing lap cement before the overlapping course is laid.

• Roll the entire surface with a weighted roller, paying attention to side lap and end lap areas. Also roll along the eave and rake edges with a weighted roller.
