Each timber window frame is made bespoke and can be stained, oiled or painted from our cultivated selection of finishes in order to achieve the required maintenance, performance and appearance.

Minimal Timber Windows

Skyline Timber Windows are highly engineered and fully tested timber windows suitable for luxury residences and commercial buildings. Available as tilt and turn windows, tilting windows or inward opening hinged windows the frames can be made in heights up to 2.8m tall. This increase height dimension allows for the creation of exclusive floor to ceiling opening windows, all with a minimal timber frame.

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.

By using a laminated timber frame with a Uf value of as little as 1.1 W/m2K it is possible to achieve fantastic levels of thermal insulation with a bespoke minimal frame. The system can also take a triple glazed unit if required for enhanced thermal insulation.

The Carminati Skyline timber window has been fully tested and certified for weather protection, thermal insulation and security.

Air Permeability Class 4 in accordance with EN 1026 – UNI EN 12207
Water Tightness Class 9A (92mm deep system) or Class 7A (78mm deep system) in accordance with EN 1027 - UNI EN 12208
Wind Resistance Class B3 in accordance with EN 12211 – UNI EN 12210
Security Resistance Class RC2

The overall Uw value for each timber window needs to be calculated for each installation in relation to the timber used, glass specification and the size of the window.

The 78mm deep system has a Uf value of 1.3 W/m2K using a Pine frame or 1.5 W/m2K using an Oak frame. The 92mm deep system has a Uf value of 1.1 W/m2K using Pine and 1.4 W/m2K using Oak.

Maximum Window Sizes

The maximum opening size for each timber window will depend on the weight of the glass as well as the hinge option you require.

Timber windows with visible hinges have a maximum weight of 130Kg per leaf. This roughly equates to an opening window of 2600 x 1100mm when using a glass pane weighing 40Kg/m2.

If you opt for concealed hinges the maximum weight per vent is 150Kg which should offer you a window opening of 2600 x 1100mm with 50Kg/m2 of glass.

For larger timber framed windows the reinforced visible hinges have a maximum weight per vent of 220Kg which will allow you to create a minimal framed window of 2800 x 1300mm with 60Kg/m2 glass.

As these systems are bespoke engineered larger opening sizes may be possible on request.
