ETFE rendszerek homlokzathoz

ETFE Systems are lightweight and transparent, offering a wide range of possibilities for innovative and spectacular building designs. These systems are cost-effective due to their low weight and reduced support structure requirements. ETFE systems are recyclable, resistant to bad weather, and offer excellent fire behavior. They are used in large roofs, shopping centers, offices, sports stadiums, and skylights, providing high transparency and minimal maintenance. TECHNICAL FEATURES & ADVANTAGES • Low weight • It can be coloured, printed on and lit • High tranparency ( 95% visible light / 85% ultraviolet ) • Excellent behaviour in fire (B-s1, d0 according to EN13501-1:2007) • Impermeable • Self-cleaning with rainwater • Permeable to UVA rays but preventing the passage of UVA C rays. • Minumum maintenance • Very resistant to bad weather • Recyclable • Good resistance to impact ( hail,etc.) • No visible mechanical deterioration • Does not discolour or harden over the years APPLICATIONS Large roofs – shopping centres – offices – sports stadiums / Skylights / etc. APPLICATION TYPES SINGLE-LAYER APPLICATIONS A single layer is used, normally with double curvature geometry. Single-layer applications depend on the mechanical prestressing, with the primary structure bearing the loads. MULTI-LAYER APPLICATIONS: INFLATED CUSHIONS These are constructed with two or more sheets of ETFE, closed at their edges and fixed to a perimeter anchoring system. They require a low-pressure, dry air inflation system produced via a unit made up of fans and a distribution network. It’s controlled using an intelligent system. Dimensions In general, the cushions, which can be circular or square, measure a maximum of 7,5 m and rectangular cushions should not exceed 4,5 mt. The length of a cushion can reach 40 mt. The dimension can be increased with the introduction of reinforcement with cable mesh and other materials. Anchorage System Cushions are fixed at the edge using a system of extruded aluminium profiles and a condensation collection tray. The system is guaranteed airtight using EPDM joints.
