Handles and Fittings

Windows & Terrace Doors



Krivaja windows and balcony doors are fitted with GU Tilt&Turn hardware.

GU Tilt&Turn hardware sys­tems stand out due to supe­rior, often tested quality: not only is the­ hardware surface galvanised, but also pro­tected against corro­sion with the­ proven fer­GUard finish.

You can choose between visible fittings with cover caps in a choice of colours to match the­ window's frame colour, or con­cealed Tilt&Turn hardware sys­tems which dis­cretely inte­grates into the­ indi­vidual design of a window.

Krivaja windows


We use industry standard RAL colours, which are a range of around 200 colours available.
For reference please use the chart below. 


We use highly protective water-based paints for our products to guarantee the maximum lifetime. New generation water-based paints form an almost rubbery covering that never reaches crystallising point so as to prevent the paint film being excessively fragile or developing cracks. 

Wood is a natural product. Some variation in colour can be expected; different types of wood, the absorption of the wood as well as thickness of coating can all lead to slight variations in the colour. These serve to underline the unique natural character of wood.

Wooden Shutters

Charm, style and genuine character

Krivaja Wooden Shutters

Shutters give to the fa?ade a timeless style and irresistible charm. During Summer or Winter, Krivaja Shutters provide protection from sun's heat and glare, and insulating rooms from the cold by providing an extra layer of warmth and protection.  Krivaja wooden shutters are produced in different variants: with fixed or adjustable louvres, with different kinds of attractive ornaments or in simple rustic shape with planks.

As with all of our products, Krivaja shutters are custom made to order to exactly meet your wishes and requirements. 

Roller Shutters - Invisible when open, sleek-fitting when lowered.

The built-in roller shutter fit in naturally and neatly because the box is directly integrated into the wall and thus invisible. They hugely improve noise and heat insulation, security, privacy and energy efficiency. Shutters can be Manually or Electrically Operated.

You can even combine it with a rollable insect screen and you will sleep peacefully next summer.
