Dupont Tyvek Supro Breather Membrane 1 x 50m. BBA Approved

Product Information

Costa Rica (solely their 20 colones bank note, Z series), [17] the Isle of Man, [18] and Haiti [19] have made banknotes from Tyvek. These banknotes are no longer in circulation and have become collectors' items. Without a breather membrane, moisture will pass through the external roof material, then build on the insulation layer, making the insulation ineffective, or even build up within the roof space, causing damp, mould and rot.

Tom Sachs used Tyvek for the outer shell of the spacesuits used in his Space Program series of artworks. [14] Tyvek ( / t aɪ ˈ v ɛ k/) is a brand of synthetic flashspun high-density polyethylene fibers. The name "Tyvek" is a registered trademark of the American multinational chemical company DuPont, which discovered and commercialized Tyvek in the late 1950s and early 1960s. Large sheets of Tyvek are frequently used as housewrap to provide an air barrier between the outer cladding of a structure and the frame, insulation, etc., allowing water vapor to pass but restricting air infiltration. [11] Tyvek Supro Breather Membrane 1m x 50m is flexible and extremely durable membranes with applications involving roofing underlay for pitched roof construction. The membrane helps to protect roofs against wind and water at the same time it increases energy efficiency. The membrane is reinforced with non-woven laminated polypropylene. Seals horizontal laps and increases thermal efficiency by decreasing the air infiltration. When Tyvek Supro Breather Membrane 1m x 50m is used it does not require any soffit, tile or ridge ventilation, which will speed up the construction process saving time and money. Applications of Tyvek Supro Breather Membrane 1m x 50m:-With wet verges, also known as verges that use mortar bedding as fixings, the breather roof membrane needs to lap onto the masonry by at least 50mm. When used with dry fix verges, the membrane needs to be laid so that it extends past the face of the gable. Penetrations Firstly, it is important to have an eaves support tray or a UV resistant membrane, that is fitted along the eaves, with the bottom edge extending into the gutter.

When moisture passes into the roof space as vapour it condenses when it reaches a cool surface. This can cause insulation to become less effective, which in turn increases heating bills. If the moisture increases over time, this can cause dampness and mould, which is unpleasant and can cause structural issues. A breathable membrane prevents moisture from entering the roof space and, in some cases, allows moisture to leave a roof space. Continue laying the lengths of the breather membrane, working up the roof. Each manufacturer should state the amount of overlap required between each length of the breather membrane. If the overlap does not coincide with a timber batten, an additional batten can be installed to ensure the overlap remains, and to prevent the tiles from touching the membrane. These can be added across the top of the underlay, but the drape of the underlay must still exist to allow the rainwater to pass down the surface of the membrane. Doctorow, Cory (February 2012).

How to install a roof breather membrane

This Tyvek Supro underlay can be used for a wide variety of applications including cold, hybrid and warm roofs. It is also perfect for wall and floor installations, low-pitched metal roofs and Scottish sarking board systems. Designed to withstand high temperatures and prolonged UV radiation while also offering superior moisture and air management for residential and commercial buildings, it comes with full IAB and BBS approval for use in all pitched roof structures.

Installing a breathable membrane improves ventilation and reduces condensation buildup while ensuring insulation remains effective. There are a variety of different breather membranes available, and the best option is dependent on the nature of your project.

Increasingly, reused Tyvek material is being used by home crafters. Protective sleeves for CDs and DVDs, tote bags, [25] and origami wallets [26] also use Tyvek-containing materials. Next, lay the breather membrane parallel to the roof eaves – normally, when installing the breather membrane the printed side should face outwards. Make sure the bottom of the membrane is overlapping the eaves support tray or UV-resistant membrane by at least 150mm, but not by so much that it will still be exposed when the roof tiles are laid.

In 2017, the DuPont company merged with another chemical company, The Dow Chemical Company to form DowDuPont. DowDuPont currently manufactures Tyvek at the Spruance plant in Richmond, Virginia, and in Sandweiler- Contern, Luxembourg. In 2018, DowDuPont announced plans to expand the Tyvek production capacity of the Sandweiler-Contern factory.

Tyvek is often used as housewrap, a synthetic material used to protect buildings during construction, or as personal protective equipment (PPE). [1] History [ edit ]
