A glass partition separates two spaces while letting daylight through. At home it divides kitchen and living room or bedroom and walk-in wardrobe; in offices it creates meeting rooms and private offices. The slim, black-framed "loft" look is the most popular today.
How much sound insulation do you need?
| Use | Recommended | XS-ALU system |
|---|---|---|
| Kitchen – living room, wardrobe | 25–30 dB | Modulusz 50 Fixed, single glazing |
| Bedroom, home office | 30–38 dB | Modulusz 50 Fixed with acoustic glass |
| Office, meeting room, private office | 38–45 dB | Twin 61 double glass wall |
Our values measured in an accredited laboratory: Modulusz 50 Fixed 31–41 dB, Twin 61 38–45 dB. For comparison, a typical steel loft door reaches 15–25 dB and a conventional interior door 20–30 dB. The table is a guide; the exact need depends on how the room is used and on background noise.
Single or double glazing?
- Single glazing (Modulusz 50 Fixed): slim, steel-look frame for homes, lofts and hotels. Glass panes up to 180 kg.
- Double glazing (Twin 61): two panes in a 61 mm frame for offices, meeting rooms and lecture halls. Up to 2 × 180 kg of glass per field.
Doors with the same slim profile can be built into both systems: hinged, sliding, pivot or bi-fold. A technical panel can also be added next to the Twin 61, for a display or charging points in the wall.
What to plan for
- The door is the weakest point. A well-insulated wall does little if there is a gap under the door. Hinged doors usually insulate better than sliding doors – the exception is the Modulusz sliding door: with its 3-axis gravity mechanism it can reach even better values if the floor on site is level.
- The joints. Gaps to the ceiling, floor and walls must be sealed elastically. Our flexible Scandinavian seal helps here: an EPDM-based expanding sealing tape that stays tight even at pressure differences above 600 Pa.
- The glass type. Safety glass (toughened or laminated) is mandatory; for sound insulation we recommend laminated glass with an acoustic interlayer.
- The divisions. Horizontal and vertical divisions create the loft character; we design them to suit the space. True divisions that split the glass into several panes usually reduce sound insulation. Where high sound insulation is needed, or where slimmer bars give a nicer pattern, we use bars bonded onto the glass.
- The survey. Every element is made to measure, so exact dimensions are essential. On request, our specialist measures on site.
Why aluminium?
It does not rust, it is light and it stays straight, so the seals close better than on welded steel frames. Black anodised as standard and paintable in any RAL colour. XS-ALU delivers over 120 projects a year with its own CE-marked system.
