FIRE-RETARDANT FOAM FOR FAÇADES AND FENESTRATION Building façades go way beyond the aesthetics of a building. Architects consider many essential aspects when designing the type of façade required: protecting the interior from outside elements, keeping it safe and comfortable, enhancing the energy performance of the interior, extending the building lifespan, creating a pleasant indoor climate, as well as considering the environment
and saving in energy costs. There have been some horrific and deadly fires as a result of incorrect façades and cladding applications on buildings. Den Braven has a range of sealants designed to retard fire for up to four hours, allowing more time for safe passage in case of fire. Known as FireProtect®, this patented range of products, available in silicone, acrylic, and hybrid and PU foam, is applied to

expansion and connection joints, such as window frames and cladding, during their installation in the finishing stages of construction. Wall applications such as field glazing of curtain wall modules where glass lights are attached to the metal framing system, need a specific sealant. Den Braven Silicone Structural Glazing Sealant is designed and tested for structurally glazed curtain. It is also used as the weather seal in glass-to-glass butt joints as it has an excellent resistance to ultraviolet radiation, ozone, high and low temperatures and water vapour. It is compatible with many types of coated glass, metal finishes, setting blocks and spacers. Weather sealing around glazing joints, to prevent moisture getting into glazing panels, is as important and this is where a product like Den Braven Silicone-NO is the sealant of choice. It has a neutral formulation, low odour and fungicidal properties. Other positive attributes of Silicone-NO is that it is noncorrosive to metals and does not discolour. This product is available in six different colours to match most aluminium substrates.
If cladding with stone and concrete slabs, Den Braven High Tack will save time and money. High Tack is non staining and capable of adhering weights of up to 25kg because it has a very high initial tack and no fixation or support is needed during curing. It is non-corrosive to metals and can be used on dissimilar materials. It’s high mechanical strength, low VOC and resistance to moisture and weather makes it ideal for many types of cladding. No matter what type of façade treatment is required, the Den Braven team of technical sales consultants are on hand to discuss the requirements of a project and, if necessary, visit the site to advise and train in the application requirements and procedures of any Den Braven Sealant. www.denbraven.co.za
