MD — centre sealing

NEO FLEXA is a system with central seal, defined by the abbreviation MD. In the opening part there are three plane seals. The middle seal remains an element of the cooperating frame and wing structure. For the buyer it is important information about the construction of the solution which is worth knowing even before comparing offers.

However, the number of sealing surfaces does not replace the data of the finished window. The leak of a particular product informs its documentation. The best conversation about NEO FLEXA therefore combines understanding of the profile construction with parameters of the ordered variant. It is an easy way to choose based on the actual characteristics of the product.

One frame, different functions

The characteristic FLEXA solution allows you to adjust the gasket to how a part of the frame is used. In the area of solid glazing, it can be removed during production. It remains in place in the opening part. Thus, one frame can handle both the wing and the adjacent fixed field.

This is a task for the window manufacturer at the construction stage. It is not an instruction to change the seal after installation. It is worth considering this feature as a design option: in advance, determine the functions of individual fields and get a window prepared for agreed use.

What does your project gain from this?

You can more consciously separate the spaces that are to open up, from those that are primarily intended to provide a view. In the living room it will be a different decision than in a small kitchen. The office may have a meaning for setting work places and in the bedroom furniture location and access to the window.

A well-chosen division should not hinder cleaning or daily handling. Therefore, apart from the appearance it is worth discussing access to the external side of the glazing and the direction of opening the wing. NEO FLEXA gives an interesting design opportunity and careful planning allows you to use it in a particular room.

Detail about which you should ask

When you talk to KM Okno, indicate which pieces you plan as permanent and which are opened. Ask for a drawing of the division and confirmation of the possibilities of carrying out the specified dimensions. It is easier to evaluate both the proportions and convenience of later use.

The force NEO FLEXA is that the design solution has a clear application. Flexible gasket does not need to be visible in the finished interior, so its role is important. It helps create a window designed for specific needs
