Technal has launched Tigal, a hybrid sliding aluminium system for high-rise applications said to it deliver ‘a balanced aesthetic that won’t detract from the overall design intent of the building.’
The system combines multi-point locking around the perimeter and a patented central sealing system said to guarantees water-tightness performance up to four times better than a traditional sliding door.
The action of turning the door handle releases pressure from the perimeter gaskets integrated around the door opening and when closing, the mechanism compresses the door against the gaskets. This seals it to provide E1200 water-tightness and up to Class 5 wind resistance of 3000 Pa.
Delivering sound proofing up to 45dB, which is ideal acoustically for an urban environment, the system also offers high thermal performance with U values up to: 0.85 W/m2K (Ug: 0.5 W/m2K).
Where doors are installed at height and exposed to potential high pressures, Technal has designed an inward ‘Pull Slide’ opening mechanism.
Unlike a conventional sliding door, the door pulls 6mm internally and will sit in either a parallel secure fixed position or slide open along its track. In the micro ventilation position this creates a hidden ventilation gap to all four sides allowing a gentle, well-dispersed airflow internally.
Tigal features a recessed threshold and disabled access threshold of 15mm high, purposefully designed for ease of use.
Some 70% of the materials and components of Tigal are recyclable and durable. The extrusion of its aluminium profiles can be produced with Hydro Circal 75R, recycled low carbon aluminium.
Floor-to-ceiling glazing is possible up to a height of 2.70m and width of 4m using one sliding and one fixed leaf, with each pane capable of weighing up to 300kg and carrying a glazing thickness of up to 52mm.
Allan Barr, UK Sales Director said: “Tall buildings are becoming more and more important for cities of the future. Tigal introduces innovations that meet the daylighting, ventilation and safety challenges of what can be a demanding but increasingly prevalent environment, putting the comfort of building users first.
“Purposefully designed for great ease of use, TIGAL’s secure micro-ventilation system and smooth, silent operation, provides a serious option for architects designing tall buildings in situations where a high performance door solution is required.”
