The Evolution-Windows structure is based on top-quality class A window profiles. The number of chambers and the profile wall thickness guarantee not only the stability and durability of the window, but most importantly, ensure improved protection against low temperatures and noise. With a smaller sash dimension (108 mm casing), more daylight enters the room, which also reduces heating costs.

The excellent insulation parameters of this sealed glazing unit guarantee low heat loss and thus reduce building heating costs.

This is possible to use in the Evolution Windows two-chamber glazing units with a coefficient of Ug=0.5W/m2K. With this solution, the Evolution Windows may be included in the energy-saving window segment (Uw of 0.8 W/m2K)

The lower the coefficient of UW thermal conductivity of a window, the less loss of energy and lower heating costs. The Evolution Windows with a Uw coefficient of 0.8 (with Ug=0.5 glazing unit and Warmatec frame) not only meet but also exceed the rigorous standards for thermal insulation, ensuring the comfort of the homeowner.

The Warmatec frame, made of high-grade stainless steel and plastic, is a combination of outstanding parameters with high aesthetic value. The frame minimises the risk of vapour condensation in the corners, which are the coldest points of the glass panel. It also improves the thermal performance of the window, thus reducing energy consumption costs (reduction of the U-value by as much as 10%). With the available selection of colours, the frame will give the window an air of elegance and will make it possible for the user to match it to the colour of the window.

Evolution Windows are fitted with an under-sill trim with gasket that enables correct and sealed assembly of the cillboard and the windowsill. The trim further improves the thermal and noise insulation of the window. A special gasket in the trim also provides additional protection against the penetration of rainwater into the room.

The higher the Rw value of acoustic insulation of a window, the greater the protection against noise. The Evolution Windows profile, with an Rw (dB) = 33 (-1, -4) coefficient, is a barrier against annoying noises and provides peace and quiet.

The mushroom striker plates are attached to the steel reinforcement, which makes breaking into the room significantly more difficult. This solution provides additional protection against burglary.

This proprietary profile reinforcement made of bent galvanised steel makes it possible to design large-sized windows. The thickness, shape and profile of the reinforcement ensure rigidity, correct function and an unchanged shape of the windows for many years. It also provides additional security for the window. The steel reinforcement system in the window sash is patent pending.

The fitting makes the handling of the window sash easier and increases protection against uncontrolled slamming. Unique, patented "SAFE LOCATION" solution - a system of specially designed fitting elements that ensure the correct sash position in the window. Additional multi-step tilt regulation by the handle ensures even more convenient use of the window.

This proprietary profile reinforcement made of bent galvanised steel makes it possible to design large-sized windows. The thickness, shape and profile of the reinforcement ensure rigidity, correct function and an unchanged shape of the windows for many years. It also provides additional security for the window. The steel reinforcement system in the window sash is patent pending.

A window unsealing mechanism to let in fresh air without the need to tilt or open the window at all. The perfect solution when the temperature is above 0°C.

A mechanism in the tilt window preventing the sash from shutting on its own. This element provides protection against the slamming of the sash due to draft.

This reliable balcony window element reduces the risk of tripping. Reducing the threshold height to 20 mm allows free movement between the flat and the terrace or balcony.

Proprietary, lean and elegant profile, with a 33% narrower floating mullion and symmetrically placed handle - the only profile of this kind in Poland. The larger glazing area compared to traditional profiles reduces the consumption of heating energy by increasing the volume of sunlight entering through the window.

The ColorFull veneering technology provides uniform colour and structure for the entire window, even when it is open. The solution is available in a wide selection of colours that will match any interior.

Unique glass gasket finishing solution at the angle of 45°; the glazing bead, harmonised with the sash curvature, and special drain plugs in Sheffield Oak colour improve the visual aesthetic of the window.

The frame minimises the risk of vapour condensation in the corners, which are the coldest points of the glass panel. It also improves the thermal performance of the window, thus reducing energy consumption costs (reduction of the U-value by as much as 10%). With the available selection of colours, the frame will give the window an air of elegance and will make it possible for the user to match it to the colour of the window.

Durable and flexible gaskets with high resistance to weather conditions, such as UV radiation, humidity or ambient temperature changes.

The dESIGN+ handle was designed in cooperation with the renowned design consultant KISKA, exclusively for the Oknoplast brand. The shape of the handle lends it a modern, minimalistic character. Furthermore, the handle is durable and comfortable to use, and its universal tint harmonises both with modern and classical interiors. Also available with a key lock

The so-called "invisible hinges", concealed between the window frame and the sash, are a unique solution developed on the basis of the Multi Power system. Concealed hinges improve the aesthetic features of the window, but also its tightness. They also make it easier to keep the blinds, window blinds and shutters clean.
