Price and reliability of the supplier
There is no need to deny it — for customers, the right price is one of the most important aspects when acquiring goods. Aluminum windows can be two times more expensive than for example PVC models, you have to find a reliable supplier. Choosing the wrong provider may lead to a variety of problems, ranging from delays to unsatisfactory quality. The second matter is the huge price difference for the same window systems between various fenestration suppliers, as they can fluctuate up to several dozen percent.
We are a reliable and trustworthy manufacturer, additionally, we constantly monitor the fenestration market in many oversea markets, thanks to this, you can be sure that by entrusting us with your order, you do not overpay for the purchased goods, and their quality will be at the highest level.
Thermal insulation
In the beginning, let’s establish that the more insulation, the warmer the window is. But it should be remembered, that panes have the greatest impact on the U-Factor, since they occupy the largest area of the window.
*U-Factor — parameter of the thermal insulation value of the window
In terms of thermal insulation, aluminum windows can be divided into cold and warm windows.
Cold profiles do not have thermal insulation inside the frames and are dedicated to the internal building only.
On the other side, warm aluminum profiles have thermal spacers that are usually made of polyamide or foam. You can also add additional spacers, which also improves their thermal properties.
Height of the frame and sash assembly
The height of the frame and sash assembly is another element that affects the window thermals — the lower the fold, the larger the glass area, which is why narrow-frame profiles have been gaining popularity recently.
This trend awakened the rivalry between aluminum fenestration producers that compete in creating systems with the lowest possible folding of the frame with the sash, which also allow as much light as possible to enter the room. Another advantage of the standard profiles with low folding is the slightly lower price of the windows, since the material consumption is lower.
From an aesthetic point of view, you have to remember that the larger the dimensions of the structure with the sash are, the higher the folding height can be — this is related to the maximum loads that a given sash and fitting can have. With larger constructions, however, the differences in the height of the assemblies are not that noticeable.
Allowed dimensions and loads
Each window system has its own maximum dimensions and load — this is another parameter that determines which system you should choose for your investment, for instance, if you want a 3-meter entrance, without the need to divide the structure into a lower sash and transom, the number of available options becomes significantly lower. But fret not — our technical consultants will help you choose solutions that meet your needs.
