Fire Retardant Breather Membrane
Having a Fire Retardant Breather Membrane in your building is essential in protecting your building and the people inside it from the dangers of fire. A Fire Retardant Breather Membrane is a material that is coated with a special coating that is resistant to fire. These materials are usually used in commercial buildings or offices. There are many different kinds of these products to choose from. They range from HPV-resistant membranes to ones that can be treated with special fire retardant compounds.
Classification of construction products and building elements on reaction to fire
Building materials and components in buildings must perform well in fire tests. This is because fires are a threat to life and property and people are the most important. The performance of a building component is a function of the product’s design, material composition and installation.
There are many construction products available that have been certified as performing well in fire tests. Some examples are flooring, wall linings, roofing, windows, acoustic panels, insulation, and fire retardant chemicals.
In Europe, testing of building materials is standardised and uses standardised test equipment. It uses data from tests to create a classification system that enables comparisons between different products.
One of the most important features of the classification system is the way that it ties fire tests to the overall performance of the product. Basically, there are three main classes: floor coverings, construction systems parts, and electrical cables.
DuPont Tyvek(r) FireCurb(r)
Tyvek FireCurb is a highly advanced building protection technology that is designed to help stop the propagation of flames, minimise damage and improve the safety of occupants. The DuPont product has been developed to provide enhanced safety and performance for any type of building.
DuPont’s breakthrough technology combines world-class materials science and chemistry know-how to deliver high performance building solutions at a competitive cost. By combining advanced properties, DuPont’s products deliver increased safety and durability while delivering beauty and enhancing the energy-efficiency of any building.
DuPont Tyvek FireCurb is backed by a unique and patented self-extinguishing coating that self-extinguishes when ignited. This coating is made of halogen-free materials and has a minimal environmental impact. It is a water-resistant membrane that forms a vapour-open lining behind ventilated facades.
Exemption from being part of an A1 or A2-s1, d0 vertical wall system
A recent consultation has recommended changes to the list of exemptions in Regulation 7(3). It was proposed to include boarding houses, hotels, hostels and cavity wall vents. Some respondents have expressed concern about this proposal, while others questioned the need for a comprehensive list of exempt products.
While most respondents agreed with the proposal, there were some comments regarding the clarity of guidance and the risks associated with closures. There are also concerns about the performance of materials.
The current regulations are clear that all external walls should have a fire classification of A1 or A2-s1, d0. This classification is based on the European classification standard EN 13501-1, which classifies materials based on smoke development and flaming particles.
EXOPERM MONO DURO 200
Partel, a leading low energy building product supplier, has launched an advanced fire-rated breather membrane. Using a combination of modern monolithic TPU technology, the Exoperm MONO DURO 200 is a breathable, UV and fire resistant, and highly breathable membrane. It’s also a great option for roofs and facades. With its fire retardant properties, EXOPERM MONO DURO 200 is an excellent choice for new build or retrofit projects.
Among other features, the membrane comes fitted with a non-combustible ECHOSeal airtight tape. The breather membrane is rated for a B-s1, d0 fire classification, which is more than ample for most buildings. This is achieved by using a halogen-free flame-retardant coating.
There are other notable features of the EXOPERM MONO DURO, including the fact that it is made of PES non-woven fabric. The membrane also offers high levels of airtightness and a long lifespan. The product is also CE-certified according to EN 13859-2.
HPV resistant membranes
The human papillomavirus (HPV) is a sexually transmitted disease caused by a circular, non-enveloped genome. It is commonly associated with warts, and in some cases, pre-cancers and cancers. HPVs are transmitted through contact with sexual partners, which means that certain individuals are at higher risk. Those at highest risk include men who are HIV positive, homosexual men, and bisexual men. Some people are also at high risk because they have a weak immune system. Vaccines are available to protect against most types of HPV.
The viral genome is approximately 8 kb in length, and contains eight open reading frames. It has two structural proteins, L1 and L2, which play critical roles in virus infection. They form inter-pentameric disulfide bonds that are necessary for the proper assembly of the viral capsid.
