The Rockdoor Montana is another Rockdoor style that has been around for a very long time, it is very similar to the Rockdoor Georgia, but it has a smaller glass panel than the Rockdoor Georgia. It comes with lots of different glass designs and textures so it suits lots of different types of houses.
The Rockdoor Montana has a sort of cylindrical glass unit, a little bit similar to the Rockdoor Arcacia but more stretched. Its a perfect composite door for the front of the house. It lets a lot of light to enter the house and can be made very private too, all the while keeping it A++ energy rating if you choose a glass design with clear backing glass.
