The Vapour Barrier category on Insulation4Less features a comprehensive range of high-quality products, each providing distinctive solutions in moisture management and insulation within buildings.

Understanding Vapour Barriers

Vapour barriers, also referred to as vapour control layers (VCL), play a crucial role in controlling the passage of water vapour within wall, ceiling, and floor assemblies, preventing unwanted moisture migration and condensation which could result in structural damage and mould growth. These barriers are often utilised in various building and construction applications to ensure a stable, moisture-free environment within the insulated areas.

Polythene Vapour Control Layers

The Polythene Vapour Control Layers available in various gauges, like 500, 1000, and 1200, supplied by NOVIA, are tailored to handle diverse applications requiring different levels of vapour resistance. Typically, higher gauge layers provide enhanced durability and better resistance to moisture ingress, suitable for areas exposed to higher moisture levels.

DIY Kits

Novia also provides DIY Kits in multiple gauges, offering an all-in-one solution for DIY enthusiasts and professional builders. These kits commonly include the essential materials and accessories required for an effective vapour barrier installation.

Specialised Vapour Barriers

Vendors like PROCTOR and ACTIS bring to the table specialised vapour barriers such as the Procheck VCL 125 and Eolis HC 135mm respectively. These products may offer additional features such as improved thermal performance, making them suitable for applications requiring enhanced insulation properties.

High-End Solutions

Strata Waterproofing provides the StrataShield, a premium, self-adhered aluminium-faced vapour control layer, offering excellent resistance to water vapour transmission and superior durability. This product is well-suited for high-end applications where an extra level of protection is desired.

Repair and Maintenance Products

Understanding the importance of maintaining the integrity of your vapour barriers, ROOFTEC provides Membrane Repair Tape, specifically designed to repair any punctures, tears, or damages, thereby ensuring the longevity of your vapour barrier system.

Breathable Membranes

ROOFTEC’s range of Breathable Membranes, categorised under BBA 95, 120, and 140, ensure optimal breathability and water resistance, which can be selected based on specific project requirements regarding permeability and durability.

Guiding Your Selection

Choosing the appropriate vapour barrier requires consideration of several factors, including the specific application (walls, roofs, floors), the level of moisture exposure, and any additional insulation requirements. Lower gauge polythene barriers or specialised vapour barriers might be suitable for standard residential applications, whereas higher gauge options or high-end solutions like StrataShield might be reserved for commercial or industrial applications with demanding specifications.

When it comes to repair and maintenance, products like membrane tapes and breathable membranes become pivotal to ensure the durability and efficacy of your vapour barrier system over time.
