DuPont™ Tyvek - Building Control Membranes

DuPont™ Tyvek® weather barriers, minimising construction, and subsequently, operating costs by helping create more efficient, sustainable residential and commercial buildings for greener, smarter solutions for modern buildingBreather membranes play a key role in protecting buildings and occupants from the elements. DuPont™ Tyvek® helps to provide long-term building protection, in addition to improving energy efficiency.

Breather membranes offer long-lasting protection against various threats to building's integrity, such as condensation and infiltration by water and air. Some products add effective fire retardancy to the list of benefits that further protect structures and their inhabitants.

Tyvek® membranes act as a vital secondary water-shedding layer, which has a highly durable functional layer that is six to eight times thicker than most common multi-layer products. This layer consists of heat-stabilised polyethylene (PE) for reliable, long-term performance and UV/heat resistance – something other breathable membranes cannot always guarantee.

Tyvek's secret is the unique single-layer structure of the membranes that comprise millions of microfibres in a homogeneous ‘maze’ that is vapour-open, yet watertight.

Tyvek® breather membrane choices are versatile, lightweight, easy to install, and are backed by DuPont’s guarantee of quality, which includes a ten-year warranty.

When searching for the right reflective breather membrane, prioritise low emissivity products, as emissivity is the basis upon which the product functions as a thermal layer.

What Makes a Tyvek® Watertight Breather Membrane Unique?

  • A DuPont™ Tyvek® watertight membrane can provide top quality durability, protection and energy efficiency for homes and buildings. For long-lasting protection against water infiltration, air infiltration and moisture, Tyvek® breather membranes provides a proven solution.

Tested and Proven Performance

  • A comprehensive ageing test conducted by the SP Technical Research Institute of Sweden has demonstrated the significantly superior durability of Tyvek® compared to the tested multi-layer products.

Thickness and Quality of the Functional Layer

  • Most of the common multi-layer underlays that were tested only have functional layers that are ca. three times thinner than a human hair. The functional layer of DuPont™ Tyvek® is ca. 6 to 8 times thicker than most common multi-layer underlays – giving long-lasting performance.

Unique Structure

  • Tyvek® consists of millions of microfibres in a unique ‘maze’ pattern. Thanks to this structure, UV and heat additives are spread across the membrane evenly to provide superior resistance and durability.

Proven Resistance to UV

  • Whereas most multi-layer underlays are made of polypropylene (PP), the functional layer in DuPont™ Tyvek® uses a material – stabilised polyethylene (PE) – that resists 100% high ultraviolet (UV) rays and heat far better.

Resists Temperatures of up to 100°C

  • Heat can seriously degrade the functionality of a watertight membrane over time, and temperatures on top of insulation sometimes exceed 80°C. So for long-term performance and investment security, DuPont™ Tyvek® breather membranes are designed to resist temperatures of up to 100°C.

Made by DuPont – Your Guarantee of Quality

  • DuPont™ Tyvek® uses a unique manufacturing process that is based on flash-spunbond technology. Every strand comes with over twenty years of experience in the EMEA underlay market and a commitment to innovation and quality woven right in.

Tyvek HouseWrap - Breather Membrane for External Walls

Housewrap breather membrane can be used in timber frame wall applications, but is also suitable for steel frame and concrete structuresHousewrap delivers the optimum balance of properties for superior performance against the elements, and helps prevent outside water from entering the walls and help to seal the home to keep outside air where it belongs.

As a consequence, HouseWrap helps reduce energy bills, because homes that stay cool in the summer and warm in the winter, and and are dry all year round, consume less energy.

Tyvek UV Façade - Ventilated Rainscreen Cladding Membrane

UV Facade ensures optimum protection of the insulation and structure in ventilated or rainscreen cladding constructions from sunlight, wind and water. The product fits naturally also for standard wall application

Tyvek UV Facade breather membrane ensures optimum protection of the insulation and structure in ventilated or rainscreen cladding constructions from sunlight, wind and water. The product fits naturally also for standard wall application. Facades with open rainscreen cladding offer new design options, but the insulation and structure still require effective, lifelong protection from the harmful effects of the elements to which it is constantly exposed. In particular UV radiation can compromise the long-term performance of secondary protection membranes.
