TERRAGRAF ventilated rainscreen facade combines a high performance cladding material with the natural beauty of extruded terracotta. An increasing number of architects use this technique not only for refurbishment, renovation and conservation projects - but also for new-build developments where the system provides unequalled aesthetic benefits, together with flexibility of design and an ability to create practically any shape or form.
TERRAGRAF ventilated rainscreen facades are a modern construction solution for both new-build and refurbishment projects. The system is ideal for schemes that need a secure and appealing cladding solution. It can be applied to all types of buildings - including residential, offices, shopping centres, schools, hospitals, hotels and industrial buildings.
TERRAGRAF is produced by the extrusion of terracotta using a blend of natural clays, creating a unique range of standard and bespoke terracotta colours that are available in large, medium and small format sizes. This, together with a variety of glazed finishes, makes TERRAGRAF the perfect facade solution for modern architecture.
TERRAGRAF provides efficient thermal insulation. In summer, the ventilated facades of exterior walls form a natural "thermal shield" that effectively protects the building against heat gains caused by direct solar radiation. The ventilation helps to maintain a constant temperature within the zone on the outer side of the insulation.
A ventilated rainscreen facade has the added benefit of providing the walls of the building with high levels of thermal inertia. This is the ability of the wall material to conduct and store heat that will optimize its performance both in cold and warm climates. In summer, solar heat is stored in the external wall. During the day this is very gradually released -penetrating through the inner wall and into the rooms at a reduced rate - thus preserving a cooler internal temperature. At night, when the outside ambient temperature is lower, the stored heat gently warms the rooms. In winter, the opposite effect occurs. The final result is a more stable climate and temperature range that helps to improve comfort and living conditions inside the building.
TERRAGRAF ventilated rainscreen facades help to create high levels of thermal insulation throughout the year, particulary as the system also accommodates varying thickness of insulation material without significantly increasing the overall wall thickness. Research has indicated that such thermally efficient walls can substantially reduce energy consumption over the lifetime of the building - highlighting the economical benefits and cost savings over other forms of construction.
TERRAGRAF ventilated rainscreen facades can also accommodate an acoustic insulation material that can significantly reduce sound transmission through the wall.
The air circulating within the ventilation zone eliminates moisture generated by condensation or capillary action.
A ventilated rainscreen facade can provide a perfect long-term protection against wind-driven rain and other weathering agents, such as ice and snow. Excessive water penetration is one of the main causes of failure of any construction. Extensive research and weathering tests show that no significant rain or snow infiltration occurs into the cavity of TERRAGRAF ventilated rainscreen facades. The angled horizontal joint between tiles is open and allows air to flow through the facade, pressurising the ventilation zone beyond and substantially reducing the risk of rain penetration - even when exposed to strong wind pressures.
TERRAGRAF is a ventilated rainscreen solution in extruded terracotta.
The TERRAGRAF system is formed by supporting extruded terracotta tiles on an aluminium substructure, and are secured with stainless steel inox clips. The system has the following advantages:
The fixing solution provided by TERRAGRAF incorporates the three basic concepts of ventilation, waterproofing and reliability. These have been effectively incorporated into the innovative solution that TERRAGRAF provides.
TERRAGRAF is a ventilated rainscreen facade solution that uses terracotta tiles with the long horizontal edges of the tile extruded at an angle of 459. This permits the use of an open horizontal joint that is more effective than in a closed-joint system for air and thermal movement, but will still prevent excessive rain penetration - even in strong winds. The tiles are secured to the vertical rail using the patented two-piece steel inox clip.
The vertical aluminium substructure of TERRAGRAF has a profile that is designed to:
The patented two-piece steel inox clip (AISI 304) that secures the tile to the vertical rail requires no drilling or mechanical fixing.
The vertical aluminium rail profile used for TERRAGRAF transfers the dead load of the cladding back to the building structure, and has an excellent resistance to any imposed wind loads and forces. The system has been thoroughly tested and is capable of supporting loads far heavier than the terracotta tiles used. The substructure has been designed to accommodate any thermal movement of the tiles and to eliminate any possible problem due to the atmospheric corrosion or bimetallic reactions between clips and rails.
TERRAGRAF ventilated rainscreen facade system can accommodate the installation of building services, such as drains, electrical and telecommunication services, water and gas pipes, ventilators and flues - without the need to incorporate bespoke access covers or plates on the visible face of the wall. The substructure for TERRAGRAF is designed to allow the removal and re-installation of the original tile - without damage - by use of a special tool and clip.
