As we encounter many mistakes when installing windows, I would like to introduce you to the advantages of using our underlay profile. The balcony underlay profile is white on the inside and its height is 13 cm, which corresponds to the standard floor composition in our company. Because the profile is hollow and has several cavities, it has very good thermal insulation properties. Compared to the standard extension profile, it is cheaper as it does not contain steel reinforcement. I firmly believe that the profile will appeal to you and that you will use it in your new projects.
Balcony base profile – 130 mm
Installation procedure
Incorrect application
Balcony doors anchored only on two steel dowels. The gap between the window frame and the floor is filled with extruded polystyrene without the use of diffusion strips!
