Highly reflective air and vapour control layer (AVCL)

Jump to:

BOS

Application

Suitable for timber, masonry or steel construction.

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.
