Product Information

Full details

This Tyvek Firecurb Housewrap is designed for builders and contractors seeking enhanced fire safety in external wall construction. Its key benefit is providing superior flame-retardant properties, including self-extinguishing capabilities and reduced smoke/droplet formation, without compromising the essential airtight, watertight, and vapour-permeable functions of standard Tyvek membranes. A potential consideration is ensuring proper installation techniques are followed to maximize its fire-retardant benefits and overall performance.

Extended Product Information

FAQs

What is the primary benefit of Tyvek Firecurb Housewrap over standard Tyvek?

The primary benefit is its enhanced fire-retardant property, featuring self-extinguishing capabilities and reduced smoke/droplet formation, which significantly improves the safety of the building envelope.

Is this membrane suitable for residential buildings?

Yes, Tyvek Firecurb Housewrap is suitable for buildings of all scales, including low-rise dwellings, due to its B-s1,d0 reaction-to-fire rating which helps limit flame propagation.

How does the Firecurb technology work?

The patented Firecurb technology suppresses sustained burning by inhibiting ignition and causing flames to die out rapidly once the ignition source is removed, without producing droplets.

What are the dimensions of this product?

This specific product comes with a width of 1.5 meters and a length of 50 meters.

Can I use standard building tapes to seal the laps?

It is strongly recommended to use only Tyvek-approved tapes or compatible sealing systems to ensure the integrity of the airtight, watertight, and fire-retardant performance of the membrane.

Does the fire-retardant feature affect the breathability of the housewrap?

No, Tyvek Firecurb Housewrap maintains the same vapour-open characteristics as standard Tyvek products, allowing moisture vapour to escape from the wall cavity.

What is the B-s1,d0 fire rating?

B-s1,d0 is a European reaction-to-fire classification. 'B' indicates limited combustibility, 's1' means low smoke production, and 'd0' indicates no flaming droplets.

Troubleshooting

Membrane appears slack or rippled after installation.

Ensure the membrane was adequately tensioned during installation. Significant slackness may require re-securing. Check that fixings are appropriate and not overloaded.

Water penetration observed at laps or joints.

Verify that all overlaps meet the minimum requirements (100mm vertical, 150mm horizontal) and that all laps, joints, and penetrations have been properly sealed with approved tape or sealant. Re-tape or re-seal as necessary.

Damage to the membrane during installation (e.g., tears, punctures).

Repair small tears or punctures immediately using the appropriate Tyvek tape, ensuring the tape extends at least 100mm beyond the damaged area in all directions. Larger areas of damage may require a patch securely fixed and taped.

Concerns about fire performance after installation.

Ensure the membrane was installed correctly according to manufacturer guidelines, with proper detailing at all junctions and penetrations. Confirm that all materials used (tapes, sealants) are compatible and approved for use with Tyvek Firecurb Housewrap.

Pros and Cons

Pros

Significantly enhances building safety with superior flame-retardant properties.
Self-extinguishing capability minimizes risk of fire spread.
Reduces smoke and droplet formation during a fire event.
Maintains the essential weatherproofing and breathability of traditional Tyvek housewrap.
Suitable for a wide range of construction types, from residential to high-rise.
Durable and easy to handle during installation.

Cons

Requires specific installation practices to achieve optimal fire-retardant performance.
May have a higher cost compared to non-fire-retardant housewrap options.
The weight, while manageable, might require attention during transport and handling for large projects.
Specific detailing for joints and penetrations is critical for both air/water tightness and fire performance.

Setup, Compatibility & Care

Setup:

Preparation: Ensure the substrate (timber, steel, or concrete frame) is clean, dry, and free from sharp objects or projections.
Application: Unroll the Tyvek Firecurb Housewrap and apply it to the external face of the wall structure. Ensure the printed side (if applicable, check product markings) faces outwards.
Overlap: Overlap subsequent courses by a minimum of 100mm vertically and 150mm horizontally. Ensure overlaps are positioned to prevent water ingress (e.g., the upper layer overlaps the lower layer).
Fixing: Secure the membrane using appropriate mechanical fixings such as staples or nails. Ensure fixings are spaced adequately to hold the membrane taut without causing excessive stress or damage. Use corrosion-resistant fixings suitable for the substrate.
Taping: Seal all laps, joints, and penetrations (windows, doors, service entries) using approved Tyvek tapes or compatible sealing systems to ensure an airtight and watertight seal.

Compatibility:

Frame Types: Suitable for timber frame, steel frame, and concrete wall constructions.
Ventilated Façades: Designed for use in ventilated rainscreen systems.
Cladding Systems: Compatible with a wide range of external cladding materials.
Sealing Products: Use only Tyvek-approved tapes and sealants for optimal performance.

Care:

Storage: Store rolls in a cool, dry place, protected from direct sunlight and moisture. Keep upright to prevent damage.
Handling: Handle rolls carefully to avoid puncturing or tearing the membrane.
Cleaning: The membrane itself does not require cleaning post-installation. Ensure the external cladding is maintained as per manufacturer recommendations.
