Sika - Sikaplan G-20 waterproofing membrane

Multilayer, reinforced with polyester mesh, synthetic, polymer, waterproofing roof membrane based on high-quality polyvinyl chloride (PVC). Contains UV radiation stabilizers and a flame retardant (in accordance with PN-EN 13956). Roof insulation membrane is used to cover flat surfaces of roofs - roof coverings mechanically attached to the roof substructure. Suitable for direct exposure in all climatic zones.

Features

• resistance to the constant exposure to wind
• resistance to mechanical damage and hail
• resistance to permanent UV radiation
• high vapor permeability
• hot air welding without open fire
• resistance to common environmental pollutants
• recyclable
