These ventilation compartments respond independently to constantly changing wind pressure. One solution is a pressure-equalized rainscreen, which relies on creating smaller compartments across a facade rather than one continuous ventilation cavity. This can cause greater stress to the cladding and the systems behind it. Higher wind loads mean more pressure will be to the exterior cladding. This type of system allows masonry to compete in the curtain wall and rainscreen arenas with a stone unit that hangs from a substrate rather than bearing on the foundation wall.įor tall buildings subjected to higher wind loading, ventilated rainscreens require a greater level of engineering. Simply put, a properly detailed rainscreen system will greatly reduce the chances of water infiltration into the wall assembly and provide a continuous convection of air improving resistance to thermal transfer in the wall cavity.Īluminum grid and clip veneer systems have found their way into the U.S.
As such, modern facades should be designed with three lines of defense in mind - the facade or veneer to deflect moisture - the airspace behind the facade to allow for drainage as well as for continuous ventilation - and a weather-resistant moisture barrier. Having a system offering open or partially-open joints on the building’s outer layer can be highly beneficial for ventilation and drainage of the wall cavity behind the facade and drying of the facade itself.
It is simple to design and build with Belstone and please contact us if technical assistance is required.Some rainscreen systems are not necessarily designed to be 100 percent rainproof. It will also protect your building from water penetration by site application of foam into chambers where components abut, to ensure your façade remains impervious to water, yet still allows the wall to breathe. With a full range of factory-produced or site-applied components, the system can cater for most architectural designs.Bel-Stone's insulating properties will help to significantly improve the thermal performance of your building and can reduce a buildings U-value by up to 60%.
As with Gebrik and Gecaro it is patented and manufactured in Belgium by Isosystems.Developed as a natural stone Rainscreen Cladding solution, Bel-stone is a durable, cost effective and non-load bearing alternative to traditional Stone Walling and the stone tiles are machined in different finishes, which are then cast in polyurethane under factory controlled conditions to produce lightweight stack-bond panels.Įach cladding ‘sheet’ measures approx 1m² and they can be mechanically fixed to either masonry, Timber or steel frame substrates on site. Bel-Stone is an Insulating Stone Cladding System, which was added to the range in 2008.
