Our expert technical team will collaborate with you, your builders, and your architect to ensure that our slimline sliding door is showcased to its full potential. We carefully level the track and drainage profile to achieve a flush floor finish from the inside to the outside. Additionally. we ensure that the outer frame remains entirely concealed both from the inside and outside, with an extended plaster finish. Typically, the
external face of the frame is exposed and presents a pleasing
appearance; however, if needed, it can be concealed using external finishing materials. Upon completion, the only visible profiles on the door are the 25mm vertical interlocking profile and the side sash locking profile. This means you get up to 94% of full glazing area which give you with an ultra-modern panoramic view.
