1.2mm Thick Al Foil Butyl Roll: Heavy-Duty Old Color Steel Roof Refurb Barrier
Product Description
| Roduct Name | Aluminum Foil Butyl Rubber Waterproofing Membrane |
| Material | Butyl |
| Color | Silver |
Butyl rubber waterproof membrane is a self-adhesive sheet available in single or double-sided variants. Mainly formulated with butyl rubber as the core component,
it is coated on reinforced or corrugated aluminum foil. This material establishes a firm bond with diverse surfaces, rendering it perfect for
color steel tiles and roof crack remediation. Featuring superior weather resistance, anti-aging capabilities, and waterproof efficacy, it securely seals bonded surfaces.
Its shock-absorbing and protective traits stay in an uncured state during its service life, adapting effectively to thermal expansion,
contraction, and mechanical fluctuations of the bonded surface. As a solvent-free product, it does not shrink or release harmful gases,
acting as an eco-friendly waterproof sealing and adhesive material.

Product Characteristics
- Exceptional bonding creep performance: When applied to concrete, it penetrates deeply into concrete pores, preventing leakage even if the concrete develops cracks.
- Superior mechanical properties: High bonding and tensile strength, along with strong elasticity and ductility.
- Strong chemical stability: Offers excellent resistance to chemicals, weather, corrosion, and UV rays, with a service life of up to 20 years.
- Simple installation, safe and eco-friendly: Free of volatile substances, non-toxic and odorless. Can be installed at -5°C; the cold-bonding process is safe, environmentally friendly, and efficient.

Construction applications
- Substrate Preparation: Clear all sharp protrusions and debris from the surface.
- Primer Application (if required): For aged color steel plates, apply a compatible water-based anti-rust primer.
- Formal Installation: Align the membrane with the guide line and use a rubber roller to roll forward and outward to eliminate air bubbles.
- Overlapping Treatment: Press the overlapping areas firmly with a roller for secure adhesion.
- Detail Handling: Reinforce details in accordance with relevant specifications for enhanced protection.

Scope of Application
-
Roof and underground waterproofing; waterproofing at structural construction joints, short edge overlaps, or detailed treatment of pre-installed membranes.
-
Sealing and waterproofing of construction joints in elevated, subway, and tunnel structures within municipal engineering works.
-
