Kloeber’s Alu-clad Composite Flush Casement and Tilt & Turn Windows

Kloeber’s bespoke and high performance alu-clad composite flush casement windows are manufactured with softwood or oak internally and an aluminium external face resulting in low U-values, high security and low maintenance.

Tilt & turn windows, or ‘European style’ windows have an innovative type of hinge mechanism that allows them to be opened inwards in two different ways; turn the handle through 90° to tilt the panel inwards for ventilation or through a further 90° to open the panel into the room on the side hinges.

Available with a variety of opening configurations and colour options, double or triple glazing with excellent U-values our alu-clad composite windows are factory finished with powder-coated external aluminium and stained or painted internal timber.

Our alu-clad composite windows are fully factory finished.  Externally, the Aluminium is powder-coated to the RAL colour of your choice from the standard colour range and internally, the timber can be finished in either transparent lacquer or painted to your choice of RAL colour.

Due to the extensive choice of colours available we are unable to provide samples.  However, a ‘RAL’ colour chart may be downloaded from the link below.  Please be aware that individual screens and printers will vary when reproducing colour charts.

The ‘RAL’ colour system used by Kloeber UK is the international standard for accurately defining paint colours. A much more extensive selection of ‘RAL’ defined colour card samples for our colour finishes is available directly from RAL colour ( on request. You may find the K7 fan deck useful when making your colour choices.
