Internal Venetian blinds
The internal venetian blind is fully integrated into Oknoplast’s insulating glass unit, offering greater privacy and free-flow control of sunlight while enhancing space, maintenance and the overall window design.

Internal venetian blind. Invisible-almost.
The blind’s ultra-thin slats (0.2 mm) let you modulate room brightness and become almost invisible when fully open. They are extremely durable thanks to a stainless-steel core and undergo NO-FOGGING treatment that removes the risk of chemical emissions inside the unit caused by UV exposure and heat.
Housed inside the glazing, the blind is sheltered from dust and accidental damage, eliminating the need for cleaning or maintenance.
All in one click.
Built into the glass unit, the blind’s movement lets you control incoming sunlight and fine-tune interior illumination.
Because everything stays inside the glazing, the internal venetian is ideal for spaces that demand extra privacy and flexible daylight control—bathrooms, kitchens or bedrooms. Book a personalised consultation at an Oknoplast showroom and find the solution that suits you best.
