Our bigSwing top- and side-hung windows are system-independent. They can be installed in any stick-system assembly, wall reveals and timberwork structures. Their elegant, filigree structural glazing look make them ideal for ventilating halls and other spaces.
Having been certified by research and test institute ift-Rosenheim as NSHEV (natural smoke and heat exhaust ventilator) for a total area of up to 5 m2, bigSwing also offers an unbeatably economical solution.
The potential applications are virtually unlimited.
Burglar resistance is another key issue at the above locations. Here too, our bigSwing top- and side-hung vents boast impeccable credentials, through their class RC2 and RC3 certification to DIN EN 1627.
To allow prompt and trouble-free installation, we supply the windows as fully pre-assembled units complete with glazing. This allows straightforward fitting of our top- and side-hung windows – in much the same way as fixed lights – with no time lost through fine adjustment of hardware etc.
Our bigSwing top- and side-hung windows are manufactured, to your specifications, with
The insulating-glass panes are provided with an enamelled, overlapping step with polished edges on all sides.
The glass panes are adhesive-bonded to the frame. They are additionally secured by means of special, hardly visible screws or filigree frames finished identically to the edge seal.
Our bigSwing top- and side-hung windows are manufactured in widths and heights of up to 6 m, and with a maximum total area of up to 6 m2. Sizes which few manufacturers can measure up to.
The achievable production sizes depend on the
We should be glad to counsel you on the optimum window sizes for your particular scheme. With all due regard, of course, to your specific requirements and preferences. After all, our ultimate goal is to find the most economical solution for you and your project.
For our frames, we exclusively use highly insulating, thermally broken multi-chambered sections with 24 mm adapter thickness. The sections can be adjusted to fit all standard stick-system assemblies, steel sections and timberwork structures. Packing for greater adapter thicknesses and the widening of the adapter edge are feasible.
The frame sections are only visible from the inside and can be anodized or coated in any required RAL or DB colour.
Innovative (230 V and 24 V) chain motors are used for our bigSwing windows. An intelligent synchronization control is additionally fitted for windows with two or more drives.
If necessary, the window's current (open/closed) position status can be monitored using reed switches or an incremental encoder system.
The wiring for industrial communications networks (bus systems) or the central NSHEV station is integrated in the window and carried within the assembly to a single connection point.
As an optional extra, we supply our windows complete with cabling. Cable lengths vary from window to window and are adapted by us to meet project-specific requirements.
In all tests conducted by independent institutes, our bigSwing top- and side-hung windows exclusively deliver top results:
The use of radar and movement detectors is possible, depending on the local conditions and occupancy. Clearly defined factors governing their application include the need for additional control cabinets and separate power supply cables, potential "blind spots" and the possibility of inadvertent interruption in non-critical cases.
Safety Class 4 applications to VFF (German Association of Window and Facade Manufacturers) data sheet: Lacker prefers in-built systems using Mayser safety edge contact strips. This obviates the need for additional power supply cables, on-site fine-tuning and cumbersome external control cabinets.
Safety Class 2 and 3 applications to VFF data sheet: For applications subject to only a small risk of accident, Lacker recommends an acoustic or visual warning signal, or a reduction of the closing speed.
