Product Overview
Factory-Direct Cold-Applied Waterproofing for Safe, Fast Construction
TY-SHIELD™ self-adhesive membrane is the modern answer to traditional torch-on systems—eliminating open flames, binders, and complex equipment. Using a premium rubberized asphalt compound, it bonds instantly to primed substrates, forming a continuous, monolithic barrier for everything from residential roofing to heavy civil infrastructure.
No-Flame Safety
Eliminates fire risk and hot-work permits. Mandatory for refineries, wooden structures, and confined spaces.
Active Self-Healing
The "creep" property of modified bitumen automatically seals minor punctures and fastener penetrations.
Peel-and-Stick Efficiency
Reduces job-site labor time by up to 50% compared to traditional torch-applied or cold-bonding methods.
Selection Guide: Understanding Reinforcement & Performance
| Classification | Options Available | Key B2B Consideration |
|---|---|---|
| Reinforcement | Class N (Non-Reinforced) / Class PY (Polyester) | Specify Class PY for heavy-duty infrastructure and high-puncture risks. |
| Performance Grade | Type I / Type II (High Performance) | Type II offers superior low-temp flexibility down to -30°C. |
| Surface Layer | PE / PET / ALU / Sand / Green Strong Film | Use Aluminum Foil for direct UV exposure and heat reflection. |
Expert Recommendation & Selection Tip
Building a Standard Roof in Moderate Climate?
Specify 1.5mm Class N with PE surface. It offers the best cost-to-performance ratio for general roofing underlayment.
Basement or High Hydrostatic Pressure?
Always use 3.0mm-4.0mm Class PY (Type II). The high-tensile polyester core prevents ruptures during soil settlement.

Key Benefits
Precision Factory-Controlled Thickness
Unlike fluid-applied systems, a factory-produced self-adhesive membrane is supplied with a defined nominal thickness. Confirm the product tolerance, substrate preparation, lap treatment, and installation quality requirements in the product TDS.
Exceptional Elongation Capacity
Maintains high elastic strain capacity, allowing it to bridge substrate cracks and accommodate significant building movement without losing its watertight integrity, even in deep below-grade applications.
Integrated Release Liner Protection
Protected by a high-strength siliconized release liner that ensures the adhesive properties remain pristine until the exact moment of application, preventing contamination and ensuring a perfect bond every time.

Installation Guide
Surface Preparation
Substrate must be clean, dry, firm, and free of dust, oil, grease, and loose particles. Apply cold bitumen primer on porous surfaces like concrete and masonry for optimal adhesion.
Weather Constraints
Do not apply during rain, snow, or strong wind. Installation below 5°C may reduce initial tack — gentle indirect warming of the adhesive side improves cold-weather bond performance.
Positioning & Alignment
Unroll the membrane and allow it to relax. Start from the lowest point on horizontal surfaces, working upward so that overlaps naturally shed water.
Peel & Apply
Peel back the release film progressively while unrolling the membrane onto the primed substrate. For double-side variants, peel liners from both faces.
Packaging & OEM
Export-Ready Roll Packing
Each roll is wrapped with protective core sleeves and polyethylene film. Rolls are stacked vertically on fumigated wooden pallets with corner protectors and strapping for ocean freight.
Private Label & OEM
Full support for custom roll labels, barcodes, brand marks, and packaging design. We supply your market with your brand — minimum order quantities vary by specification.
Storage Recommendations
Store rolls vertically in original packaging, in a cool, dry, covered area away from direct sunlight. Recommended storage temperature: +5°C to +35°C. Shelf life: 12–18 months from production date.

Frequently Asked Questions
What is the difference between Class N and Class PY self-adhesive membranes?
Class N (Non-Reinforcement) membranes have no internal carrier and rely on the polymer-modified bitumen compound itself for mechanical integrity. They are available in thinner gauges (1.2–2.0mm) and are suitable for less demanding applications. Class PY (Polyester Felt) membranes incorporate a high-strength polyester reinforcement carrier, offering thicknesses of 2.0–4.0mm with significantly higher tensile strength and puncture resistance — the preferred choice for heavy-duty roofing and below-grade waterproofing. We also offer glass fiber felt (G) reinforced variants for specialized applications.
Which surface material should I choose — PE, PET, aluminum foil, or sand?
PE film is the most economical and widely used — suitable for general roofing and underground applications where UV exposure is not a concern. PET film offers higher reflectivity and heat resistance. Aluminum foil provides superior UV reflection, vapor barrier properties, and aesthetic finish for exposed applications. Sand/mineral (D) surface is designed for torch-on system compatibility and slip resistance. Our sales team can recommend the optimal surface for your specific project conditions.
What is the difference between single-side and double-side self-adhesive membrane?
Single-side self-adhesive has adhesive coating on the bottom face only, with a surface film (PE/PET/ALU/Sand) on top — it is the standard for most roofing and basement applications where the membrane is the outermost waterproofing layer. Double-side self-adhesive has release liners on both faces, allowing it to bond two substrates together — commonly used as a sandwich layer between concrete slabs, for lap-joint reinforcement, or where additional bonding strength is required.
Is a primer required before installing self-adhesive membrane?
While the membrane can bond directly to clean, smooth metal and some non-porous surfaces, we strongly recommend applying a cold bitumen primer on concrete, masonry, and blockwork. Primer seals the substrate surface, eliminates dust, and significantly enhances long-term peel adhesion — especially critical in below-grade applications where hydrostatic pressure is a concern.
Can self-adhesive membrane be installed in cold weather?
Installation is not recommended below 5°C as the adhesive compound becomes less tacky. However, gentle indirect warming of the adhesive face (using a hot air gun on low setting, not an open flame) before application can restore bond performance. For projects requiring winter installation, please contact us about our enhanced cold-weather formulation options.
How does self-adhesive membrane compare to torch-applied SBS membrane?
Self-adhesive membrane is the safer, faster alternative — no open flame, no hot-work permit, no specialized torching equipment. Torch-applied SBS membranes offer higher heat resistance and are preferred for exposed roofing in hot climates. Self-adhesive membranes excel in confined spaces, refurbishment projects, chemical plants, and anywhere fire safety is paramount. Many projects use both: torch-on SBS for exposed roofs and self-adhesive for basement and foundation systems.
What is the minimum overlap for self-adhesive membrane seams?
Side laps require a minimum 100mm overlap; end laps require a minimum 150mm overlap. All seams must be firmly rolled with a hand roller to ensure a continuous, monolithic waterproof seal. Stagger end laps between adjacent rows by at least 300mm to avoid creating a weak point.
What is the shelf life and how should rolls be stored?
Shelf life is 12 to 18 months from the production date when stored properly: vertically in original packaging, in a cool, dry, covered area away from direct sunlight, at temperatures between +5°C and +35°C. Do not stack rolls horizontally during long-term storage as this can cause deformation. Remove packaging only at the moment of application.
Do you offer OEM / private label for self-adhesive membrane?
Yes. We provide full private label and OEM support for wholesale and distribution partners — including custom roll labels, barcodes, brand-name printing, bespoke packaging design, and customized roll dimensions. Minimum order quantities apply and vary by specification. Contact our export team with your requirements for a tailored quotation.
