Thin Timber Frames

These thin framed timber windows have been sculpted by Carminati Serramenti who have been creating bespoke joinery since 1894. The unique timber framed window has ultra-slim frames thanks to the strong laminated timber profiles, available in Oak or Fir.

Skyline Timber Windows are available as tilt and turn windows, tilting windows or inward opening hinged windows in heights up to 2.8m tall.

Externally you can hide all timber framing to create the appearance of a frameless window opening. Alternatively, you could choose aluminium external finish, an all glass external finish or leave the timber frames on show.

High Performance Values

A double opening option for the tilt and turn windows offers a slim central profile with the option to have either opening as a tilt or turn window.

Minimal timber frames offer us an extremely high level of thermal performance with Uf values from the frame along as minimal as 1.1 W/m2K. When combined with highly insulating glass we can achieve Uw values far below 1.0 W/m2K.

The timber window has been fully tested for thermal and weather resistance. The handle choice is extremely varied allowing for a bespoke internal design to your room.


The Carminati timber window range is an inward opening window system available in a bottom hung window, side hung window or versatile tilt and turn window.

As well as single opening windows we can also engineer double vent windows with a minimal central profile where the windows meet.

As with the Carminati Skyline Lift and Slide Door the system is available in two depths; the 78 series (for double glazing) and the 92 series (for triple glazing).

Frames and Finishes

The beauty of the Carminati Skyline system is the slim timber framing. The windows have an overall ultra slim frame of 60mm with the venting frame itself at 50mm wide.

The timber frames are available in two timber choices; Oak or Pine. Both timber frames are available in a range different finishes, please view the product information sheet for more information. 

You can opt to clad the timber frame externally with aluminium for a low maintenance external finish. The aluminium can be powder coated any RAL colour to suit the external finish of your building. You could even step the glass over the external frame for an all glass external finish.

Alternatively, you can hide all external timber frames of this inward opening window with external building finishes to create a completely frameless effect.

Size and Performance

The maximum size of these timber windows is determined by the weight of the glass. The maximum weight of each window is 150kg and the windows can be installed with a maximum height of 2.8m.

Timber frames are natural insulators and that allows the Carminati Skyline system to offer exceptional levels of thermal performance. The Uf value of the frames depends on the timber choice and depth of the installation.

Oak frames have a Uf value of 1.3-1.5 W/m2K and the Pine Frames have a Uf 1.1-1.4 W/m2K.

Fully tested for weather resistance the timber windows have achieved high levels of weather resistance:

Air Permeability Class 4

Wind Resistance Class B3

Water Resistance Class 7A-9A
