Acoustic Window Handles: Tokyo, Belgrad and Zero Series
Windoform's acoustic window handles are a family of design series, including Tokyo, Belgrad and Atlas, complemented by the minimal Zero line. "Acoustic" is the name of the series, not a performance figure, so choosing between them is mainly a question of design language, ergonomics and fit with the profile system. This guide compares the series and shows how to choose.
1. Why the Acoustic Handle Matters
The handle is the part of a window people touch every day, and often the only piece of hardware visible from the room. In residential and commercial projects where architects want a coordinated look, a handle series with several related models makes specification easier and keeps the appearance consistent from floor to floor.
The Windoform acoustic range brings together Tokyo, Belgrad, Atlas, Ege, Anka, Akdeniz, Asya and Parma. Each series has its own design line while sharing the same production and quality control. One point is worth stating clearly: the sound insulation of a window depends on the profile, glazing, seals and installation. Treat the handle as a design and function choice, and take acoustic values from the window system supplier.
2. The Tokyo Acoustic Series
Tokyo is one of the core models of the acoustic range and a common starting point for projects that want a contemporary handle on PVC windows. When you evaluate Tokyo for a project, check:
- compatibility with your gear and the required spindle length;
- whether the grip suits the users, for example in housing, offices or hotels;
- the finish options that match your profile colours;
- whether matching door handles are needed elsewhere in the building.
3. Belgrad Acoustic and Belgrad Flat Slim
Belgrad is a second main line of the acoustic range. For projects that prefer a low-profile appearance, the Belgrad Flat Slim version offers, as its name suggests, a flatter and slimmer variant of the same design idea. Having both versions in one family is practical: you can use the standard Belgrad in most rooms and switch to Flat Slim where the design calls for a more discreet handle, without changing the character of the project.
As with every handle, confirm fixing and gear compatibility on a sample of your profile before ordering in volume.
4. Zero and Atlas: Acoustic and Minimal Design
Atlas belongs to the acoustic range and gives specifiers a further design option alongside Tokyo and Belgrad. Zero, on the other hand, is aimed at projects that favour a minimal appearance. Used together, these lines cover both a classic and a reduced design language within one supplier's portfolio.
You can compare the models on the acoustic window handles page and see the wider range, including lockable, ABS, curved, axial and outward-opening handles, on the window handle page.
5. Criteria for Choosing a Series
- Technical fit: spindle, fixing, operating positions and, for Rehau profiles, the need for a profile adapter.
- Design consistency: choose a series that works in every room type of the project.
- Security needs: where windows must be locked, compare the lockable window handle options.
- Finish: match the handle colour to the profile and to other visible hardware.
- Continuity of supply: for long-running projects and dealer stock, choose a series you can reorder easily.
6. Technical Verification and Contact
Windoform develops its handles through in-house R&D and produces them in its own factory in Torbalı, İzmir, using robotic zamak, plastic and aluminium injection. The company works with ISO 9001 and ISO 14001 management systems and holds TSE certification for window handles. Technical information is available in the catalogues, and our team can send samples so you can verify the fit on your own profile. Contact us at +90 232 854 70 00 or info@windoform.com.tr.
Frequently Asked Questions
Does an acoustic window handle improve sound insulation on its own?
No. "Acoustic" is the series name. Sound insulation depends on the profile, glazing, seals and installation, so rely on test data from the window system supplier.
What is the difference between Belgrad and Belgrad Flat Slim?
Both belong to the same design family. Belgrad Flat Slim is the flatter, slimmer version for projects that want a more discreet handle.
Can I combine acoustic handles with Windoform door handles?
Yes. Windoform also produces door handles, sliding handles and hinges, so you can source the visible hardware of a project from one manufacturer.
