Versatile tensioned fabric system for glazed facades, rooflights and atria. Suitable for external use only.Features and benefits:Fitted with a single barrel tension system which produces smooth, quiet travel.Built around a unique spring mechanism which constantly holds fabric flat and adapts to the surrounding environment.Relieving rollers allow the blinds to follow the direction of the glass, in any angle or direction.Whatever the scale or shape of the glazing, tensioned fabric can be applied with accuracy and discretion.With angles and curves to suit application.Reliable and robust.CE marked.TESS 400:Manufactured to overcome the challenges of curved glazing.Rectangular in shape.Ultra-thin cables maintain fabric tension.No guides required.Discrete design.TESS 401:Manufactured to cover 90° triangles and corners.Shaped like a right-angled triangle.Appropriate for flat or curved surfaces.No guides required.TESS 402:Manufactured for special or uneven shapes, including domes and tapered windows.Trapezoidal in shape.An adaptable solution.No guides required.Ultra-thin cables maintain fabric tension.TESS 420:Used where tensioned fabric is required for lighter structures; designed to minimize the load imposed.Rectangular in shape.With aluminium guide rails for maximum stability and to retain the tension force of the blind.Provides strength and weather resistance.The weight of the system is distributed via multiple fixing points.CE marked; wind class 3.TESS 440:Clean-cut design to help blend in with facades.Rectangular in shape.Designed to deliver reliability.Slim, 5 mm diameter stainless steel wire guides and flexible brackets make it easy to design into the glazing surround for near invisibility.Suitable for both internal and external use.CE marked; wind class 3.Installation:TESS 400, 401 and 402: Bottom or back of the window.TESS 420 and 440: Top, back or sides of the window.Weight (excluding fabric):TESS 400, 401, 402 and 440: 12.5 kg (approximately).TESS 420: 10.5 kg (approximately).Fabric area:TESS 400: Maximum fabric area of ≤16 m².TESS 401: Maximum fabric area of ≤9 m².TESS 402: Maximum fabric area of ≤16 m².TESS 420: Maximum fabric area of ≤16 m².TESS 440: Maximum fabric area of ≤16 m².Technical characteristics:Fabric draw: TESS 400, 402, 420 and 440: ≤6500 mm; TESS 401: ≤5000 mm.Fixing load: TESS 400, 401 and 402: ≤36 kg (per bracket); TESS 420: ≤7 kg (per fixing point); TESS 440: ≤100 kg (per bracket).Fabric tension: >100 N.Operating temperature: 0–55°C.Motor: 15 Nm (17 rpm).Maximum running time: 4 minutes.Fabric speed: 5 m per minute (approximately).
