Protect your Project with DuPont Tyvek

Whether it's a skyscraper or a single-family home, the building envelope is an essential line of defence against air, water and wasted energy.

Tyvek Building Envelope Systems offer solutions that exceed building code requirements through industry leading technical properties of water resistance, optimal water vapour permeability, air resistance and sustained durability.

Tyvek HomeWrap

Tyvek HomeWrap is a non-woven, non-perforated sheet made from spun high-density polyethylene fibres to form a strong, uniform web. The fibrous structure is engineered to create microscopic pores that resist bulk water and air penetration while allowing moisture vapour to pass through.

Supro Roof Underlay

Tyvek Supro is a self-supporting fire retardant synthetic roof underlay, designed for use in both roofs and walls. It is made by laminating spunbonded high density polyethylene to a non-woven polypropylene membrane, providing a strong, weather resistant barrier with excellent vapour permeability.

3 rolls of 2.7 x 30m Tyvek HomeWrap
