Tyvek Pro Underlay felt 60 m² – 1.5 × 40 m

Tyvek Pro is a high-quality underlay covering that combines waterproofing and wind protection with good breathability — it allows water vapor to pass through, enabling effective ventilation without a separate air gap. 

The roll covers 60 m² with dimensions 1.5 m x 40 m. The functional layer of the Tyvek Pro material is about six times thicker than many alternatives on the market. This makes the product especially suitable for constructions where you want to minimize or eliminate traditional ventilation between the underlay and insulation.

Tyvek Pro can also be used as an effective wind barrier in exterior wall constructions.
