Product Information
Full details
This B2C Vatec100 breathable membrane is designed for homeowners and construction professionals seeking to enhance roof and wall weather protection. Its primary benefit is blocking wind-driven rain while allowing trapped moisture to escape, preventing condensation and extending the lifespan of your roof structure. A potential caveat is its UV protection is limited to 6 weeks, requiring timely installation of final roofing materials. Key features include a durable 3-layer construction, high vapor permeability, and versatility for pitched roofs and timber frame walls.

FAQs
What is the primary function of this breathable membrane?
The primary function is to protect the roof structure from wind-driven rain and external water while allowing trapped moisture vapor to escape, preventing condensation and extending the roof's lifespan.
How long does the UV protection last?
The UV-stabilized surface provides protection for up to 6 weeks during installation. It is important to install the final roofing materials within this timeframe.
Can this membrane be used as a primary waterproofing layer?
No, this membrane is designed as an underlay or breathable barrier and must be used in conjunction with primary roofing materials like tiles, metal sheets, or shingles.
What are the dimensions of the membrane?
The membrane is typically 1.5m wide, with lengths available in rolls such as 20m or 50m.
How do I ensure the membrane is installed correctly?
Install with the printed side outwards (if applicable), ensuring proper overlaps horizontally and vertically. Secure with appropriate fixings and seal all laps and penetrations with compatible tapes or sealants.
Is this membrane suitable for flat roofs?
This membrane is primarily designed for pitched roofs and timber frame walls. Its suitability for flat roofs may vary and should be confirmed based on specific project requirements and local building codes.
What is the weight per square meter (g/m2)?
The membrane is rated at 100g/m2, indicating its density and robustness.
Troubleshooting
Membrane appears to be leaking after installation.
Verify that all overlaps and penetrations have been sealed correctly. Check for any accidental tears or punctures that may have occurred during installation and repair them with appropriate membrane tape.
Condensation is still forming within the roof structure.
Ensure the membrane is installed with the correct side facing outwards (if applicable) and that there is adequate ventilation in the roof space. Confirm that the membrane is not completely sealed off from external air by other building components.
UV exposure has exceeded 6 weeks.
Protect the membrane from further UV degradation immediately by installing the final roofing materials as soon as possible. Assess the membrane for any signs of brittleness or degradation before proceeding.
Difficulty achieving a tight seal at edges or junctions.
Use manufacturer-recommended tapes or sealants specifically designed for breathable membranes to ensure watertight and airtight seals at all laps, seams, and junctions.
Pros and Cons
Pros
- Excellent breathability prevents moisture buildup and potential structural damage.
- Robust protection against wind-driven rain, ensuring a watertight seal.
- Durable construction offers long-term performance and resistance to tearing.
- Versatile use cases for both roofing and wall applications.
- Simple to handle and install, saving time and labor costs.
Cons
- Limited UV protection (up to 6 weeks) requires prompt installation of final roofing.
- Requires proper ventilation strategies to work effectively.
- May require specialized tools or techniques for certain complex roof designs.
- Not a primary waterproofing layer, needs to be combined with other roofing elements.
Setup, Compatibility & Care
Setup:
- Ensure the roof deck or timber frame is clean, dry, and free from debris.
- Unroll the membrane, ensuring the printed side (if applicable) faces outwards.
- Install the membrane horizontally, starting from the eaves and working upwards.
- Overlap subsequent courses according to manufacturer recommendations (typically 10-15 cm horizontally and 15-20 cm vertically).
- Secure the membrane with appropriate fixings (e.g., staples or battens), ensuring not to over-tighten.
- For pitched roofs, install underlayment according to local building codes and manufacturer guidelines.
- Ensure the UV-stabilized surface is exposed to the elements for no longer than 6 weeks before final roofing is installed.
Compatibility:
- Compatible with most common roofing materials including tiles, metal sheets, and shingles.
- Suitable for use in conjunction with various insulation types in pitched roofs and timber frame walls.
- Ensure compatibility with any tapes or sealants used for laps and penetrations according to their respective manufacturer guidelines.
Care:
- The membrane requires no active care once installed and covered by final roofing materials.
- During the 6-week UV exposure period, inspect for any damage and make necessary repairs using appropriate membrane repair tape.
- Keep the material stored in a cool, dry place away from direct sunlight and moisture before installation.
