Vapour Control Layers | Vapour Control Barrier | VCL

Vapour Control Layers (VCLs) are essential components in modern construction, playing a crucial role in managing moisture and air quality within buildings. Our VCL category offers a diverse range of products suitable for various applications, ensuring the integrity and longevity of your building envelope.

How Vapour Control Layer Works

VCLs function by limiting the passage of warm, moist air from the interior of a building into the colder parts of the structure, such as walls, roofs, and floors. This control is crucial because when warm air meets cooler surfaces, it can condense into water, leading to potential issues like rot and mould. By installing a VCL on the warm side of the insulation, typically just behind the internal finish, builders can effectively manage moisture levels within the building envelope.​

Types of Vapour Control Layers

There are several types of VCL available, each suited to specific applications:​

Reflective Vapour Control Layer

Reflective VCLs, such as Reflectatherm Plus and Ultrablock series, are designed to offer enhanced thermal performance. These layers not only control vapour transmission but also reflect heat, making them ideal for projects where thermal efficiency is a priority.

Standard and Premier Vapour Control Layer

Products like Procheck Standard 300 and Procheck Premier 500 are excellent choices for general construction needs. These VCLs provide reliable moisture control, suitable for walls, roofs, and floors across various building types.

Polythene Vapour Control Layers

Polythene VCLs, available in different gauges, are versatile and cost-effective solutions for a wide range of construction projects. They are particularly useful in applications where simplicity and ease of installation are essential.

Reinforced and High-Performance VCL

For more demanding applications, STRP Reinforced and Profoil 861 Vapour Control Layers offer enhanced durability and performance. These products are well-suited for environments with higher risk of mechanical damage or where additional strength is required.

Speciality Vapour Control Layers

Our range includes specialised products like FlameOut Block Flame Retardant VCLs, offering additional safety features in fire-sensitive environments. The VC8 Reflective and VC200 Reflective layers are tailored for situations where air leakage control is as crucial as vapour control.

DIY Kits for VCL

For smaller projects or DIY enthusiasts, our category includes a variety of DIY Kits in different gauges and specifications. These kits provide an all-in-one solution, simplifying the selection process for residential or small-scale applications.

Choosing the Right Vapour Control Barrier

Selecting the appropriate VCL depends on several factors:

• Building Type and Location: Consider the climatic conditions and the specific needs of the building.
• Thermal Performance: Reflective VCLs are preferable in projects where energy efficiency is a key consideration.
• Strength and Durability: In areas prone to mechanical stress or where longevity is vital, reinforced or high-performance VCLs are recommended.
• Fire Safety: In fire-sensitive areas, flame-retardant VCLs should be considered.
• Budget and Application: Polythene VCLs and DIY kits are suitable for a wide range of applications and offer a balance between performance and cost.

Our extensive range of Vapour Control Layers caters to all these needs, ensuring you find the perfect fit for your project.
