Grey routine days with a lack of sunlight make you think about how to get more light. But how at the same time not to sacrifice the heat? Viknar’off HST Portal provides maximum light transmission meanwhile remaining an energy efficient component of your home. Noise from the highway, the airport and other outside sounds will not disturb your rest and comfort: thanks to three sealing contours and double-glazed unit up to 52 mm, the Viknar’off HST Portal system perfectly blocks this noise. Triplex or tempered glass will make the system even more reliable and take care of the safety of your home and property.
The strong Gealan S9000 profile, square steel reinforcement with a thickness of 2 mm in the frame and reliable Siegenia hardware allow Viknar’off to produce constructions with an area of more than 15 m². The maximum size is achieved due to the unique function of dry pasting of a double-glazed unit in the STV sash which is presented in Gealan profiles.
Allow yourself to choose exactly what you want and do not compromise with your dreams, since we offer 63 options for decorative coating and 8 colours of the spacer bars in the double-glazed unit. Real aesthetes should pay attention to the additional option of lighting in the aisle.
Viknar’off HST Portal lightweight parallel sliding constructions connect the space of your room. The Siegenia ECO Pass threshold with a slight height of 5 mm above the floor level will take care of it. For maximum comfort we recommend installing a parallel sliding system with a drainage system that will not let excess moisture, melt water, dust or dirt get into the room.
