Flush Casement

Casement Flush is a traditional English outward opening window. The window sashes are fitted flush into the frame which makes them look elegant. Outward opening helps to save the space inside an interior and allows to design window sill area to one’s liking. Flush Casement windows are a perfect choice for environments with harsh weather conditions, especially with strong wind.





We use only the highest quality timber. The most popular timber species are oak, pine and meranti.
Other timber species are available upon request. Our timber is supplied from FSC­certified sources and is 80­ – 100 years old.


In our Flush Casement windows, we use ROTO hardware.


Windows may be single, double or triple glazed, depending on customer’s needs. Triple glazed units 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. We use opaque and translucent Teknos Gori paints due to their durability and resistance to fading. There is a possibility of designing dual colour window frames.
