Sky Sheet 300 is a polyethylene vapor barrier film manufactured from SABIC-blown polyethylene with a blend of low-density polyethylene (LDPE) resins. This barrier provides exceptional resistance to corrosion, moisture, and harsh environmental conditions. It is engineered with high-quality European standards for maximum durability.
Key Features:
✔️ Weather and corrosion-resistant.
✔️ Maintains flexibility at temperatures above 80°C.
✔️ Prevents moisture and chemical gas penetration.
✔️ Protects oil pipelines and water tanks from corrosion.
✔️ Functions as a high-performance vapor barrier in concrete slabs and foundations.
✔️ Acts as a separation layer between bitumen insulation and polystyrene insulation boards.
✔️ Shields against sun, wind, rain, dust, and debris.
