Description
Adhered base sheet membrane composed of SBS modified bitumen and a non-woven polyester reinforcement.
UNITS PER SKID: 25
Material Use:
ELASTOPHENE 180 PS DG is a high-performance SBS-modified bitumen base sheet membrane designed for use in multi-layer roofing and waterproofing systems. It is primarily used as a base ply in built-up roofing systems for commercial and industrial flat or low-slope roofs. The membrane provides excellent waterproofing protection and mechanical strength, making it suitable for new construction and roof replacement projects.
System Components:
This membrane is typically used as part of a multi-layer SBS-modified bitumen roofing system. It serves as the base sheet and is installed in conjunction with a compatible cap sheet such as SOPRALENE or ELASTOPHENE cap membranes. The system may also include a primer (such as SOPREMA ELASTOCOL 500 or ELASTOCOL STICK) applied to the substrate to enhance adhesion, especially when installed over concrete or wood decks. Hot bitumen (SEBS or oxidized) is used as the adhesive medium for installation.
Applications:
ELASTOPHENE 180 PS DG is suitable for use in commercial, industrial, and institutional roofing applications. It is designed for use in multi-ply SBS-modified bitumen systems where high durability, flexibility, and waterproofing performance are required. It is ideal for flat or low-slope roofs and can be used in both new construction and re-roofing projects.
Application Details:
The membrane is installed by unrolling it into a bed of hot bitumen (SEBS or oxidized) applied with a mop. The top surface is covered with a thermofusible plastic film that melts during installation to ensure proper bonding with the subsequent layer. The underface is sanded to facilitate adhesion to the hot bitumen. The membrane includes two selvedges protected by a silicone release film to ensure proper overlap and sealing between adjacent rolls.
Special Notes:
- Installation Temperature Range: The membrane should be installed in ambient temperatures above -18 °C (0 °F), as it maintains flexibility and performance at low temperatures.
- UV Resistance: ELASTOPHENE 180 PS DG is not UV stable and must be covered with a UV-resistant cap sheet or protective surfacing.
- Thickness: Minimum thickness is 2.2 mm (85 mils), with selvedge areas slightly thicker at 2.3 mm (90 mils).
- Reinforcement: The membrane is reinforced with a non-woven polyester mat, providing excellent tensile strength and elongation properties.
- Storage: Rolls must be stored upright with the selvedge side on top. If stored outdoors, they must be protected with an opaque cover to prevent UV degradation and moisture infiltration.
- Compatibility: This membrane is compatible with other SOPREMA SBS-modified bitumen products and should be used in conjunction with SOPREMA-approved primers and cap sheets for optimal performance.
- Coverage: Each roll measures 15 m x 1 m (49 ft x 3.3 ft), covering approximately 49 m² (528 ft²) before accounting for overlaps.
This product is CSA A123.23 Type B, Grade 3 certified, ensuring compliance with Canadian roofing standards. It offers excellent puncture resistance, dimensional stability, and compound stability up to 121 °C (250 °F), making it a reliable choice for demanding roofing environments.
