Description

Tyvek Reflex, a breather membrane with a metallised surface, enhances thermal efficiency by reflecting radiant heat during summer and minimising convective heat loss in winter. It provides secondary protection against external moisture for various wall systems and is especially effective in lightweight construction like timber or metal frame systems.

This low emissivity breather membrane is a preferred choice for masonry and internal insulation upgrades. It is both durable and water-resistant with a high-density polyethylene composition.

Features & Benefits: DuPont Tyvek Reflex Breathable Membrane - 0.48m x 100m Roll

  • 100m length x 0.48m width x 220µm thickness
  • Roll size of 48m²
  • 0.09 emissivity
  • Made from high density polyethylene
  • Includes a metallised surface
  • UV exposure: 4 months
  • 4.2kg in weight
  • Reflects radiant heat during summer and minimises convective heat loss in winter
  • Improves thermal efficiency

A material's emissivity refers to its surface's ability to emit energy through radiation. A material with a low emissivity value is more reflective, making it an effective thermal insulation layer when used with an air gap. Tyvek Reflex, for example, has an emissivity value of 0.09, which means it reflects 91% of radiant heat, resulting in improved thermal comfort and airtightness. This leads to a decrease in the overall thermal transmittance or U-value of the construction.

Standards & Certification

  • Certification: BBA Certified and CE Marked

Please note:

  • The Tyvek metallised tape will be required for any joints or laps.
