On roof valleys, ensure the breather membrane is extended by a minimum of 300mm on each side, measured from the centre of the valley. At abutments, the underlay should be turned up by at least 100mm – this will create a secondary water-resistant barrier. Roof verges 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]

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. Tyvek is used by the United States Postal Service for some of its Priority Mail and Express Mail envelopes. [15] 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. PenetrationsInstalling 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. Tyvek coveralls are one-piece garments used for personal protective equipment. They are usually white, commonly worn by mechanics, oil industry workers, painters, insulation installers, and laboratory and cleanroom workers where disposable, one-time use coverall is needed. They are also used for some light HAZMAT applications, such as asbestos and radiation work, but do not provide the protection of a full hazmat suit. Tychem is a sub-brand of Tyvek rated for a higher level of liquid protection, especially from chemicals. DuPont makes Tyvek clothing in different styles from laboratory coats and aprons to complete head-to-toe coveralls with hoods and booties. The latter was notably used by the Japan Ground Self-Defense Force as emergency limited CBRN gear during the Fukushima nuclear incident. [32] 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.

Features & Benefits: DuPont Tyvek Supro Breather Membrane Felt Underlay Roll - 50m x 1m

History of Weather Barrier". www2.dupont.com. Archived from the original on 2012-10-05 . Retrieved 2018-11-28. Breathable roof membranes are crucial in pitched roofing projects, as they prevent the build-up of condensation, which can lead to damp, mould and rot. They allow moisture to move out of the roof space, whilst still preventing rainwater ingress, ensuring that the roof space stays dry. Here at Roofing Superstore, we have a number of breathable roof membranes available for your latest roofing project, from Tyvek Supro breather membrane to Cromar’s breathable membrane, TLX breathable pitched roofing felt, Klober Permo and more.

Tom Sachs used Tyvek for the outer shell of the spacesuits used in his Space Program series of artworks. [14]

Reinforced with laminated nonwoven polypropylene, this durable Supro breather membrane felt underlay from DuPont Tyvek is extremely water-resistant, as well as vapour-permeable and airtight. It is ideal for use with all unsupported and supported roofs without needing any ridge, tile or soffit ventilation. As a result, you can save on both time and money throughout the construction process. Protective Clothing for Ebola Virus Disease (EVD)" (PDF). www.dupont.com. 2014. Archived from the original (PDF) on February 25, 2015 . Retrieved 1 June 2023. If the roof includes ridge ventilation, the breather membrane must be cut on each side of the ridge to ensure the path of ventilation is still clear. If there is no ridge ventilation, the breather membrane should go over the ridge, and overlap each side of the ridgeline by the required overlap. Roof valleys New Products and Services".

How to install a roof breather membrane

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:- workflow-process-service. "Crime scene protection with DuPontTM Tyvek | DuPont South Africa". www.dupont.co.za . Retrieved 2018-11-28. We also offer breathable felt membrane.Engineered to optimise moisture management and air circulation, our breathable felt membranes effectively prevent condensation buildup while promoting a healthy indoor environment. Enjoy prolonged structural integrity, as these membranes act as a reliable barrier against water infiltration while allowing trapped moisture to escape. Whether for roofing or wall applications, our breathable felt membranes ensure superior protection, energy efficiency, and durability. Timber frame breather membranes have been manufactured to be slightly thinner and less heavy duty than their breather membrane counterparts. This allows them to be installed vertically, making them perfect for use in timber frame construction.
