Delta Ultra Control VCL - Vapour Control Layer

A highly reflective air and vapour control layer (AVCL), offers low emissivity to enhance thermal performance of

walls, ceilings and floors.

Features and benefits:

• Strong insulating properties.
• Delivers an airtight system with sealed laps.
• Helps avoid condensation risk in accordance with BS 5250:2011+A:2016.
• Excellent nail tear resistance.
• High tensile strength, tough and durable.
• low emissivity reflective surface.
• Enhances thermal performance of the structure when used in a still air cavity.
• Easy to cut and lightweight to handle.
• Available with integrated tape to seal overlaps to ensure radiant heat is reflected back into the structure, minimising absorption and energy transfer.
• Class 1 surface spread of flame to BS 476-7: 1997 fire test on building materials and structures. Method of test to determine the classification of the surface spread of flame of products.
• Thermal resistance: 0.78m²K/W heat flow horizontal to EN ISO 8990.
• Emissivity of the surface (0.02³) unaged to BS EN 15976.
• Emissivity of the surface (0.03³) aged to BS EN 15976.
• Resistance to water penetration to BS EN 1928 with mods Class W1.
