Stormproof Casement windows are typical English windows which open outwards. This brings two main advantages – the space around the window can be fully utilised, plus, the insulation is enhanced during strong winds which push the masses of air against the window.





While manufacturing of our windows we use pine, oak and meranti. Other timber species areavailable upon request. We use only the best quality wood which is 80­100 years old. Each woodis FSC­certified, which attests to the fact that it comes from organic farming, honoring theenvironment.


ROTO hardware is used in Casement Stormproof windows. It is chosen individually to everyproject.


Windows may be single, double or triple glazed, depending on customer’s needs. Triple glazedunits have the best thermal insulation.We offer a wide range of glass types:
– soundproof
– esg- energy efficient
– ornamented
– fireproof
– anti burglar
– solar control

We also offer one­way mirrors and other types of custom made glass. Every window has an aluminum spacer bar which can be replaced with a warm spacer bar to increase thermal insulation.


Frames are available in a wide range of RAL colours. Opaque and translucent Teknos Gori paintsare used due to their durability and resistance to fading. There is a possibility of designing dualcolour window frames.
