As well as looking smart, they are very practical: they give daytime and night-time privacy, protection from the sun and darken the room for sleeping at night. You can change the angle to improve any one of these functions.
Aluminium Venetian blinds
Although we do have an option of supplying aluminium Venetian blinds with a 50mm slat, almost all of the aluminium Venetians we make use 25mm slats. They come in a variety of colours, which can be seen here: https://www.uniline.co.nz/Product/Detail/6/Privasee-Venetian-blinds/1
They are useful in both domestic and office environments. Being relatively light weight, they can cover a wider window than PVC or Marupa blinds. Some people like to raise them every day, while others like to use the tilt function only to change the amount of light and visibility they afford.
