Premium wooden windows by BARTYN: protection, function and value retention

BARTYN manufactures project-specific, FSC®-certified wood and wood-aluminium windows for sophisticated architectural demands. We exclusively process selected quality timbers such as pine, spruce, larch, oak, meranti and Eucalyptus grandis – further speciality timbers such as Accoya are available on request. Our made-to-measure products combine state-of-the-art burglary protection, sound insulation at the highest level and uncompromising energy efficiency.

Our performance limits at a glance:

  • Burglary protection: Up to resistance class RC3 according to DIN EN 1627.
  • Sound insulation: Full spectrum of all sound insulation classes 1 to 6 (weighted sound reduction index Rw up to over 50 dB).
  • Thermal insulation: GEG-compliant versions as well as high-end constructions for the passive house standard (Uw ≤ 0.8 W/(m²K)).

Burglary protection according to DIN EN 1627: mechanical security RC

Windows and French windows are among the primary targets in break-in attempts. At BARTYN, effective
protection results from the mechanical unity of solid wood profiles, state-of-the-art hardware technology and resistant glazing.

Depending on your individual security needs, we plan and manufacture your wooden windows with tailor-made
security components:

  • Security hardware and mushroom-head locking: Effectively hinders the window sash from being levered open.
  • Burglar-resistant glazing: Use of penetration-resistant laminated safety glass (VSG) – mandatory for classes RC2 and RC3.
  • Lockable window handles: With integrated drilling protection against unauthorised operation from outside.

While class RC2/RC2N is generally recommended for private residential ground floors, BARTYN realises solutions up to class RC3 for buildings with increased security requirements.

Sound insulation: maximum quiet from class 1 to class 6 (DIN 4109)

Effective sound insulation protects health and increases living comfort in urban areas, on main roads or in the vicinity of airports. BARTYN covers the entire technical spectrum and manufactures sound insulation windows in all sound insulation classes (SSK 1 to SSK 6) according to DIN 4109.

  • SSK 1 to 3 (Rw 25 to 39 dB): Optimum protection with moderate outdoor noise and in purely residential areas.
  • SSK 4 to 5 (Rw 40 to 49 dB): High-performance protection for buildings on busy main roads and railway lines.
  • Sound insulation class 6 (Rw ≥ 50 dB): Maximum acoustic decoupling for extreme noise exposure (e.g. in the direct vicinity of an airport).

This extreme sound reduction is achieved through the precise use of asymmetrical pane thicknesses, optimised cavities between the panes (SZR) with noble gas filling, special laminated sound insulation films and multi-level sealing planes in the solid wood frame.

Thermal insulation and energy efficiency: GEG-compliant and passive house standard

Modern wooden windows by BARTYN are a central building block for the thermal quality of the building envelope.
They minimise transmission heat losses and sustainably reduce heating costs.
When windows are replaced in existing buildings, the current German Building Energy Act (GEG) requires a maximum thermal transmittance of Uw ≤ 1.3 W/(m²K). BARTYN wooden windows with modern triple thermal glazing remain significantly below these legal requirements. Through thermally optimised profiles and highly efficient spacers (“warm edge”), we achieve top values that easily meet the strict criteria for the passive house standard (Uw ≤ 0.8 W/(m²K)).

Durability through material quality and constructive protection

The natural durability of our windows is based on the careful selection of wood species (pine, spruce, larch, oak, meranti, Eucalyptus grandis, Accoya) and the perfect interplay of constructive wood protection and environmentally friendly, multi-layer coating systems. They protect the material in depth against moisture and UV radiation while preserving the natural material’s ability to diffuse.

  • Optional additional fourth coat of varnish: For surfaces exposed to extreme wear and maximally extended maintenance intervals, we optionally offer an extended coating system with a fourth coat of varnish. This ensures even higher resistance to mechanical impact and extreme weather.
  • The premium alternative: For extreme, unprotected weather exposure we offer wood-aluminium windows – inside the natural aesthetics of wood, outside an absolutely maintenance-free, rear-ventilated aluminium shell.

Value retention and care

High-quality building components retain their function and aesthetics for decades. Retaining the value of your BARTYN
wooden windows only requires minimal, regular measures:

  • Cleaning and surface care: Annual application of gentle care products recommended by the system supplier to keep the protective layer elastic.
  • Hardware maintenance: Light oiling of the moving hardware parts according to the manufacturer’s specifications for permanently smooth operation and optimum contact pressure.
  • Seal inspection: Visual inspection of the circumferential seals for elasticity in order to guarantee airtightness and sound insulation in the long term.
