There are a few key moments when changing the window frames. We will try to explain these in a most straightforward way in order to facilitate you when choosing new window frames that will last several generations without changing.

Budget
First you have to determine a budget so that you know what you can afford. PVC windows and doors are the most affordable. This doesn’t mean that they are of low quality. It is just that they are made of plastic and are less durable compared to wooden or aluminum window frames.

Glazing
Next, it is very important to choose the best glazing for you. The glazing makes up for 80 % of the area of the windows- actually, it is even more important than the profile of the window frame. According to european standards the window frame should have minimum double glazing (2 glasses) with one being a low-emission glass (Ka glass) and the other- white float glass. This type of glazing has quite sufficient insulation characteristics.  For even better insulation a combination of multifunctional and white float glass is used.

Noise protection
For the best noise protection we again turn to glazing. The best protection is made of a glazing combination of triplex glass and white float glass. Even higher standards of noise protection are achieved when we use triple glazing (3 glasses).

Security
We achieve the highest degree of safety and security when using glazing with triplex type glass. It is highly durable and doesn’t break but only cracks.

Fittings
Windows open with the aid of the fittings of the window frame. The fittings are supremely important for each window or door that opens. We trust only quality german fittings so that you feel safe when you order new windows for your home or factory in our company.

Colours
The standard colour is white. This is not only because the white windows are the most affordable in terms of price. The white colour is the most durable since it is not affected by the sunrays in the same way as window frames with dark colours. The white-coloured window frames are the most widely spread not only in Bulgaria but also in Austria, Belgium, Germany, France, Italy and others. However, also quite popular is the colour that imitates the one of wood: golden oak, walnut, dark oak or wenge. These are very beautiful and naturally complete the façade of your home.  

Types of window frames
We offer several types of window frames- wooden, PVC, aluminum. We hope that we have been quite thorough in order to help you in choosing the best type for you.

Advice and recommendations
If you have limited funds we recommend that you choose economy class of window frames but a one that has well-insulated glazing.The glazing accounts for the largest portion of a window and the investment in such is worth it in a long–term perspective. The money saved from electricity will compensate for the difference in price really quickly.
