Welcome to the Airtight Membranes category, where we offer an array of products designed to enhance the air tightness and energy efficiency of your building projects. Airtight membranes are essential in construction for creating barriers against air leakage, thus improving thermal performance and reducing energy costs.

Types of Airtight Membranes

1. Self-Adhesive and Vapour Permeable Membranes

  • Example: Wraptite Self-Adhesive Vapour Permeable Air Tightness Membrane

  • Ideal for: Providing air tightness while allowing moisture to escape, thus preventing condensation issues in walls and roofs.

     

2. Torch-On Underlay Membranes

  • Example: Danosa Torch On SBS Underlay

  • Use Case: Suited for flat roofs, these membranes offer robust waterproofing and are applied using a torch-on method.

     

3. Breather Membranes

  • Example: Black+ Breather Membrane DIY Kit

  • Function: These are used in wall and roof systems to allow moisture to escape, reducing the risk of condensation, while preventing moisture ingress.

     

4. Reflective Vapour Control Layers

  • Example: Reflectatherm Plus Reflective Vapour Control Layer

  • Purpose: These layers are designed to enhance thermal insulation by reflecting heat back into the building and controlling vapour diffusion.

     

5. Aluminium Faced Membranes

  • Example: StrataShield Self Adhered Aluminium Faced AVCL

  • Best For: Applications requiring high moisture control and a barrier against vapour transmission.

     

6. Specialized Membranes

  • Examples: Radon Barriers, UV Resistant Membranes (e.g., Traspir Zenit UV 210)

  • Applications: Tailored for specific needs like radon gas mitigation or UV resistance in exposed environments.

     

7. DIY Kits

  • Example: Novia Black+ Ultimate DIY Kit

  • Convenience: These kits come with all necessary components for small-scale or DIY projects, simplifying the installation process.

     

Choosing the Right Membrane

When selecting an airtight membrane, consider the following:

  1. Application Area: Roof, wall, or floor – each area may require a different type of membrane.
  2. Building Regulations: Ensure the product meets local building codes and standards.
  3. Climate Conditions: Some membranes are better suited for humid, rainy, or cold climates.
  4. Building Design: Factor in the overall design, including ventilation needs and thermal insulation requirements.

  5. Ease of Installation: Consider the installation process and whether a DIY kit or a professional-grade membrane is more appropriate.

     

Our range includes products from trusted vendors like Proctor, Danosa, Novia, and Rothoblaas, ensuring quality and reliability in every purchase.
