Tyvek® Reflex
Verified by manufacturer 25 days ago
BBA Agrément Certificate
Certificate type
Reflective wall breather membrane .
Application
Suitable for use in any wall system that requires secondary protection from external moisture. The low emissivity membrane is particularly effective in lightweight wall construction such as timber or metal frame systems and is also popular for masonry and internal insulation upgrades.
Description
A strong, heat reflective water-resistant breather membrane that helps to improve thermal efficiency by reflecting radiant heat in summer and reducing convective heat loss in winter.
Features and benefits:
- High thermal performance due to low emissivity surface, provides 0.54 thermal resistance.
- Airtight and water resistant, yet vapour-open, properties help to create an energy efficient construction that lasts the lifetime of the building.
- Keeps building cool inside by blocking 91% of radiant heat in summer.
- Lightweight, flexible, easy to install.
- Can be left uncovered for up to four months while retaining full performance.
- Trusted performance and proven durability.
- Fully BBA, BRE and TRADA certified; approved by UKTFA – covers compliance with codes and standards.
- CE marked.

Accessories | Tyvek® Metallised Tape. Guidance for specification option: Single sided tape composed of an acrylic adhesive on a metallised Tyvek carrier. For sealing laps in metallised Tyvek® membranes and making good around penetrations, pipework, windows and door openings. Roll size: 75 mm x 25 m. Tyvek® Double Sided Tape. Guidance for specification option: Double sided acrylic tape for sealing laps in Tyvek membrane and bonding to smooth surfaces. Excellent adhesion properties under extreme conditions. Strong initial tack. Roll size: 50 mm x 25 m. Tyvek® Butyl Tape. Guidance for specification option: Double sided butyl based sealant, used to seal fixing penetrations in a Tyvek membrane and form a moisture and airtight seal between a Tyvek membrane and most commonly used building materials. Tape is compatible with brickwork, blockwork, masonry, timber, metalwork and most plastic products. Roll sizes: 20 mm x 30 m, 50 mm x 30 m. Tyvek® FlexWrap NF. Guidance for specification option: A stretchable and flexible tape made up of three components: a crimped DuPont™ Tyvek® top sheet providing a water tight layer, the butyl mass as an adhesion layer and a paper release liner. It provides excellent watertight adhesion to all Tyvek® breather membranes around non-straight penetrations, such as dormers, door sills, chimney breasts, pipe penetrations and any custom shapes. Roll size: 2280 mm x 22.9 m. |
