Discreet, square-edged handles fit perfectly to the straight-lined design of Internorm studio windows. Despite square edges, handles can be gripped well. Lockable handles or Secustik handles ensure more security.

Next to insulating and toughened glass from our own production, we can also offer a range of special glazing.

Choose from our wide range of colours and design your window according to your requirements. Along with our standard colours, we can offer you a large selection of other colours such as weather-resistant hirest  and many more.
