Note that specific product variations can affect properties, and actual performance depends on application conditions, thickness, and manufacturer specifications.

Aspect	JY-ZPT Polymer Self-Adhesive	SBS Modified Bitumen	TPO	PVC
Composition	Polymer-modified bitumen with a self-adhesive rubberized asphalt layer, often incorporating SBS-like polymers for elasticity; topped with polyethylene film; release liner on adhesive side.	Bitumen modified with SBS polymers for flexibility; available in cap sheets with granules; can be self-adhered, torch-applied, or cold-adhered.	Thermoplastic polyolefin; single-ply sheet with UV stabilizers; often white for reflectivity; no plasticizers needed for flexibility.	Thermoplastic polyvinyl chloride; includes plasticizers for flexibility; available with or without KEE additives for enhanced weather resistance.
Installation Method	Self-adhesive: Peel release film and apply to prepared surface; no heat or torches needed; overlaps sealed by pressure; suitable for occupied buildings to avoid fire risks.	Torch-applied, cold-adhesive, hot-mopped, or self-adhered; torch method requires skilled labor and fire precautions; self-adhered similar to JY-ZPT but may need primers.	Heat-welded seams for fusion; mechanically attached, adhered, or induction-welded; requires specialized equipment and certified installers; sensitive to wind and contamination.	Heat-welded or adhered; mechanically attached or induction-welded; quick for large areas but needs attention to plasticizer compatibility.
Durability/Lifespan	Typical 15-25 years; resistant to water penetration under pressure; multiple layers in systems add redundancy; vulnerable to high heat flow if not granulated.	20-30 years; multiple layers provide puncture resistance and redundancy; withstands building movement; may require recoating every 10-12 years.	15-25 years; good puncture resistance (40% better than some alternatives); prone to cracking in extreme cold (-30°C); formulation changes address early failures.	25-35+ years; high puncture and fire resistance; performs well under ponding water; consistent long-term data with fewer formulation issues.
Flexibility	Elongation around 200%; flexible down to -10°C; suitable for moderate temperature swings but may stiffen in extreme cold.	High elasticity (up to 300% stretch); flexible from -30°C to +120°C; handles thermal cycling well due to rubber-like properties.	Limited below -20°C (brittle at -30°C); arctic grades extend to -35°C; stable in heat without flowing.	Superior due to plasticizers; remains flexible in various temperatures; KEE versions enhance long-term flexibility.
UV Resistance	Relies on polymer modification and surface film; may need protective granules or coatings for extended exposure.	Granulated surfaces provide resistance; polymer helps but recoating needed in severe conditions.	Contains stabilizers (2-3% min.); white versions degrade reflectivity by 40% in 2 years from dirt.	Good with UV inhibitors; KEE additives improve long-term resistance; less prone to rapid degradation.
Chemical Resistance	Moderate; resistant to water and some contaminants but not ideal for oils, greases, or harsh chemicals.	Fair; withstands general exposure but degrades with petroleum-based substances.	Resistant to many chemicals except acids, greases, oils; suitable for moderate environments.	Superior; handles oils, greases, jet fuel; KEE enhances for harsh industrial settings.
Energy Efficiency	Limited reflectivity unless modified; black or dark surfaces absorb heat; not primarily designed for cool roofing.	Granulated surfaces moderate heat; not highly reflective unless coated white.	High SRI in white (reduces cooling by 20-30% initially); reflectivity drops over time.	Available in reflective colors; good for cool roofs with stable SRI.
Cost (Installed per sq ft)	$12-18; lower labor due to self-adhesion; minimal equipment needs.	$15-20 for torch; self-adhered 40% higher; recoating adds ongoing costs.	$14-18; welding equipment adds 20% to labor; arctic grades increase by 15-20%.	$15-20; higher initial for KEE versions; long lifespan reduces lifecycle costs.
Pros	Easy, fire-safe installation; good adhesion on irregular surfaces; cost-effective for below-grade or low-slope uses.

Customer Reviews

Here are some customer reviews from various users around the world, highlighting different aspects of the product based on their experiences.

John D., USA (Contractor, Focus: Ease of Installation)
"I used this membrane on a basement foundation project. The self-adhesive backing made application straightforward without needing torches or extra tools. It stuck well to the concrete after priming, and I could backfill the next day. There were a few wrinkles in spots where the surface wasn't perfectly smooth, but overall, it saved time compared to liquid options."

Maria S., Canada (Homeowner, Focus: Durability in Harsh Weather)
"In our cold winters, I applied this to an exterior wall for moisture control. It held up through freeze-thaw cycles without cracking, and there's no sign of peeling after a year. The elasticity helped with minor shifts in the structure. It's not the cheapest, but it seems reliable for long-term use in wet conditions."

Ahmed K., UAE (Engineer, Focus: Adhesion and Compatibility)
"We installed it in a tunnel lining where dust was an issue. The adhesive bonded effectively to the prepared surfaces, even with some irregularities. It integrated well with other materials like bentonite for added protection. No major issues with adhesion so far, though we had to be careful with overlaps to avoid gaps."

Sophie L., UK (Builder, Focus: Cost-Effectiveness)
"For a municipal culvert repair, this membrane provided decent coverage at a reasonable price point. It resisted water flow during tests, and the lack of VOCs meant safer working conditions. Installation was quicker than expected, but we needed extra rolls for curved areas, which added to the cost slightly."

Karl M., Germany (Project Manager, Focus: Environmental Adaptability)
"Applied in an underground storage cavern with high humidity. The membrane maintained its integrity over extended exposure without degrading. It's flexible enough for rocky surfaces, but we noticed minor dust accumulation during construction that required cleaning. Performs as expected in stable environments."

Li Wei, China (Construction Supervisor, Focus: Overall Performance with Minor Drawbacks)
"Used on subway station walls for anti-seepage. The three-dimensional application helped with bonding to post-poured concrete, and it handled vibrations without issues. However, in very humid spots, we saw some initial softening before it set fully. It's functional for urban projects but requires proper surface prep."
