Larger spans in reach

With increasing demand for 60mm curtain wall systems, architectural aluminium systems specialist Sapa has launched the Technal MY curtain walling system, which can offer a glazed surface area of up to 12m².

The MY curtain walling system provides a 62mm wall structure allowing for maximised glazed surfaces of up to 12m², weighing up to 680kg. A larger glazing pocket gives increased glass edge clearance to accommodate building movements that can be expected on larger projects.

Architecturally interesting facades can be created using different external effects, frame asymmetry as well as facetted constructions. Design options include flat pressure plate caps, which provide a smooth appearance.

The MY aluminium curtain walling can be combined with Technal’s PY 55 door, STII door and FY 65 window.

Technal’s national sales manager Allan Barr said: “The MY packages many features that are available from our current curtain walling offer in one flexible yet fully integrated system.

“What we were finding was that customers were wanting to stretch the capabilities of the 50mm systems. The profile strength in the new range can avoid the need for secondary supportive steel structures while delivering those all-important uninterrupted views.”

MY curtain wall meets energy consumption reduction requirements and in the high insulation version, the system offers Passivhaus performances with U-values as low as Ucw = 0.61 W/m2k.

MY is an optimised solution with fewer profiles, a simple tooling system, and is available as 7m bar lengths for larger spans.
