Single frame wood aluminium window FENIX FIXED

Durable, energy efficient and easy to maintain Fenestra Fenix Fixed windows are an excellent option for any home. The single frame triple glazing wood aluminium window does not open, thus allowing the construction of large scale windows. The frame and architrave are covered with aluminium profiles from the outside. It can be used side by side with an identical to-open window section inside the same architrave. The windows can be ordered and fitted with air vents, mosquito nets, venetian blinds, ventilation frames and hatches as well as decorative edging. The model comes in a variety of finishing options. All our products are tested by approved test labs.

Window glazing can serve as a decorative element in the home or, where necessary, obscure the view from the outside or the inside. For example, Satinovo glass is an excellent choice for washrooms as it lets in light while shielding you from the eyes of outsiders. We offer something for everyone.

Mosquitos, flies and other unwelcome guests tend to be a problem in spring and summer, this is where an insect screen comes in handy. The screen can be set up on the inside and added to windows that open.

Stylish venetian blinds that match your home’s decor make life as convenient as possible. We recommend ordering them with the windows, as they are much more costly and time-consuming to install later.

Air vents help ensure functioning ventilation in your home by keeping indoor air fresh and healthy. The vents are designed to mix outdoor air with the warm indoor air in the upper part on the room, thereby avoiding draught.
