Delta Ultra Control VCL - Vapour Control Layer
Verified by manufacturer 4 months ago
Highly reflective air and vapour control layer (AVCL)
Application
Suitable for timber, masonry or steel construction.
Description
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.
