Flat Roof Vapour Barrier (VCL)

Description

Damplas VCL Vapour Barrier

Damplas VCL is a high-performance vapour control layer designed to protect flat roof structures from moisture damage. By effectively preventing moisture penetration and improving building airtightness, Damplas VCL helps to maintain structural integrity and enhance energy efficiency.

Key Features:

• Moisture Barrier: Stops moisture from entering and damaging roof structures.
• Improved Airtightness: Creates a more energy-efficient building by reducing air leakage.
• Enhanced Insulation: Helps to prevent heat loss and maintain comfortable indoor temperatures.
• Versatile Application: Suitable for both warm and cold deck roof designs.
• Durable Construction: Made from a strong, durable polythene film.

Technical Specifications:

• Color: Translucent
• Size: 4m x 25m (100m2)
• Composition: Blown extruded polythene film, approximately 125 microns thick.

Installation:

• Warm Side Installation: Damplas VCL should be installed on the warm side of the insulated structure, following the guidelines of BS5250:2002.
• Continuous Sheet: Ensure a continuous sheet is installed to prevent moisture intrusion.
• Seamless Sealing: Carefully seal all holes and seams to maintain a secure barrier.
• Overlapping and Taping: Overlap sheets by 75mm and tape all edges to secure them.
• Moisture Content: Ensure the frame’s moisture content is 20% or less before installation.
• Temperature Considerations: Avoid installation in temperatures below 5°C.
