Timber/aluminium windows can be designed completely in 68 mm
Source: bauelemente bau
Thanks to its new design of the Gutmann Spree TWT rain protection rail and a window sill rebate of 30 mm, Gutmann Bausysteme GmbH has succeeded in producing a timber width of 68 mm at the bottom of the frame for classic timber windows - including professional installation of an aluminium window sill.
Due to the higher proportion of glass and the narrow face widths, the new Mira TWT offers improved U-values. Classification to RC 2 is planned for burglar resistance. Tests are currently underway for resistance to driving rain, wind load, air permeability and impact resistance - according to the company, Mira TWT will achieve at least the standard values here.
The special feature of the new Mira TWT/Mira contour TWT: fabricators can build a complete window with the 68 × 68 mm timber cross-section. Frame, sash, transom or set timber - all components can be designed in 68 mm. The face width is 110 mm in the double rebate. All standard opening types and window shapes can be implemented.
Mira TWT
- With a 68 × 68 mm timber cross-section, the new system is based on the optimized profile geometry for CNC machine technology.
- Also available with timber thicknesses of 78 mm and 88 mm.
- Narrow appearance with a face width of 110 mm.
- Quick and easy installation thanks to the use of clip holders.
- Modern design thanks to the large glass surface, combined with slim face widths and optimum glass bonding for large elements.
- Classic timber windows can be produced with the Spree TWT rain protection rail and a 30 mm window sill rebate for professional installation of an aluminium window sill.
- Only a small additional investment is required, as it is possible to work with extensions to the tool inventory.
Mira
The Mira timber/aluminium system with its diverse range of profiles offers tailor-made solutions for both residential and commercial buildings. Behind the classic, offset appearance is solid technology with outstanding performance values. All standard window constructions, opening types and window shapes - including slanted windows, round, segmental or pointed arches - are available in various profile designs.
- The Mira system can be designed as a double rebate, single rebate or slanted rebate construction.
- The profiles are available with radii on the visible edge and with an angular look.
- The product line is rounded off by a variety of transom and set timber profiles for optimum profile joints and optimized building connection solutions.
- Thanks to the tried-and-tested fastening technology, the aluminium shells are easy and economical to install on the wooden part.
- The available plinth heights make it possible to compensate for various timber overhangs.
- A wide range of seals offers solutions for different areas of application.
- The design as a composite sash construction, sash variant or slanted rebate construction offers further window design options. The frame connections are available welded or with sturdy punched corner joints.
- The system is also suitable for the timber/building bronze version with punched corner joints.
Mira contour
- The system can be designed as a double rebate, single rebate or diagonal rebate construction.
- Mira contour can be used in a classic style as an offset look for the standard timber cross-section in the Gutmann Mira system.
- The use of the VFM sash enables a flush design - without changing the standard timber sash cross-section in the Mira system.
- Narrow sash face widths round off the system.
- The range of accessories from the Mira system can be used without restriction.
- The frame connections are available welded or with sturdy punched corner connections.
Mira contour integral
The flush-mounted Mira contour integral timber/aluminium system has a narrow frame view with a completely concealed sash up to the insulating glass pane and allows a large amount of light to enter through large glass surfaces.
Together with the milled glazing bead on the sash, this design is an economical development in timber/aluminium window construction. The glass is protected in the timber rebate, resulting in good thermal insulation: Mira contour integral achieves Uf values of 0.86 to 1.1 W/m²K at the frame and is therefore suitable for use in passive houses. The glass is held in place by an aluminium profile. The aluminium frame is generously ventilated and is fixed to the wood with sturdy brackets without tension. This allows the wood to breathe. The profiles create clear lines with small radii on the visible edge. Set timber and transom profiles in various widths also allow complicated window divisions. The frame connections can be either welded or realized with stable, punched corner joints. All fittings from timber window construction can be used here.

Architectural bronze
Gutmann has been supplying the market in the EU, Switzerland, Russia, the United Kingdom and the USA with architectural bronze profiles based on the Mira, Mira contour, Braga and Lara metal composite systems for over 15 years. A large number of special profiles made of architectural bronze have now been realized for large properties. With its lively surface, architectural bronze can be used in a variety of ways. The copper metal harmonizes with numerous other building materials. The natural shades from copper red to bronze brown and anthracite lend individual accents to modern buildings.
