Vapour Control Layers (VCLs)

Vapour Control Layers (VCLs) – Essential for Moisture Management & Energy Efficiency

Vapour Control Layers (VCLs) are crucial components in modern building construction, designed to regulate moisture movement, improve thermal efficiency, and maintain indoor air quality. By controlling the diffusion of water vapour, VCLs prevent condensation, reducing the risk of mould growth and structural deterioration.

Benefits of Vapour Control Layers:

✔ Moisture Management – Prevents water vapour ingress and reduces condensation-related damage.
✔ Energy Efficiency – Minimises heat loss, stabilising indoor temperatures and lowering energy consumption.
✔ Improved Air Quality – Controls humidity levels, preventing mould and mildew growth for a healthier environment.

Types of Vapour Control Layers:

• Polyethylene Films – High-resistance plastic membranes used in walls, floors, and roofs.
• Bituminous Membranes – Durable, waterproof layers ideal for flat roofs and below-ground applications.
• Metal Foils – Vapour-tight aluminium sheets that enhance insulation performance.
• Specialised Coatings – Liquid-applied vapour barriers for concrete, wood, and masonry surfaces.

Correct Installation for Maximum Performance:

✅ Sealing – Ensuring airtight joints, seams, and penetrations with tapes, adhesives, or sealants.
✅ Proper Placement – Positioned on the warm side of insulation to prevent internal condensation.
✅ Integration with Other Components – Designed to work with windows, doors, and ventilation systems without compromising efficiency.
