Du Pont breather membranes protect buildings and their occupants

DuPont has an outstanding track record as a strong and reliable manufacturer with a long standing commitment to sustainable growth, meeting the specific needs and requirements of all customers, such as architects, specifiers, builders, roofing contractors, and the like.

Through the use of its unique and highly advanced technological materials, DuPont products protect the environment for future generations, as Tyvek® roofs, walls and floor membranes are extremely efficient - cutting energy consumption, heating bills and greenhouse gas emissions to the atmosphere, and thus reducing the risk of global warming.

Wrapping a home with DuPont™ Tyvek® weather barriers is like putting a windbreaker over a sweater.

DuPont™ Tyvek® helps to reduce nasty drafts, optimise insulation, control air leakage, hold out bulk water which can lead to mold and mildew, and cut energy bills. Tyvek® can also breathe, which means that if moisture does get inside your walls, DuPont™ Tyvek® lets it pass through to the outside.

Protects buildings and their occupants through the use of its unique and highly advanced technological material, Tyvek®.

At the same time DuPont products protect the environment for future generations, as Tyvek® roofs and walls are extremely efficient - cutting energy consumption, heating bills and greenhouse gas emissions to the atmosphere, and thus reducing the risk of global warming.

Unique technology is used to create the fibre structure of Tyvek®.

Backed by more than 30 years experience worldwide it ensures superior durability and long term performance which provides the following benefits:

Tyvek® is the only product with a unique functional layer that is entirely made up of millions of unique micro fibres. These are bonded together to create a maze that stops water penetrating, whilst allowing water vapour to freely move through the fibres.

Moisture management and protection from the external elements

Minimises air and water ingress, whilst allowing moisture to migrate freely and safely into the atmosphere as required in Building Regulations/Standards (Tyvek® high vapour permeability).

Helps minimise condensation to protect the building structure, preserve the integrity of the insulation material and thus its performance and provides a healthy indoor climate.

Energy efficiency

Helps to reduce energy loss due to uncontrolled air infiltration (Tyvek® air tightness).

The new generation of Metalised membranes reflect the heat inside the building during winter leading to increased energy savings (Tyvek® low emissivity).

Helps to minimize CO2 emissions by reducing energy consumption.

Comfort

Tyvek® membranes control the movement of heat, air and moisture in a building by minimising air leakage and therefore allowing greater environmental control to the occupants. The new generation of Metalised membranes helps to reflect external heat during the summer.

Certified and durable materials

UV and heat stability ensure long term performance. CE marking and warranties available. In the event of a fire, Tyvek® membranes will not give off any harmful gasses.

Building regulations compliance

Tyvek® membranes help to satisfy items a, b & c of Approved Document C(2) for England & Wales and Sections 3.10 and 3.15.4 of The Scottish Building Standards – Resistance to moisture/Precipitation and Interstitial condensation

Tyvek® membranes also assist in satisfying Approved Document L for England & Wales and Section 6.2.5 of the Scottish Building Standards – Air permeability/Air infiltration

Tyvek® Metalised membranes further assist in Part L and Section 6.2 compliance by improving thermal performance
