Our aluminium windows and sliding doors open easily!

We make aluminum sliding doors for terraces and balconies from the best warm and durable aluminum profile manufactured in Germany or Belgium. It is not only about the aluminum profile but a holistic system of structures that allow for high reliability and ease of use. We make our balcony doors only from the profile of the best European manufacturers – Schüco or Reynaers.

One of the main elements of glazing is double-glazed windows. We ourselves make our double-glazed windows and therefore we guarantee their reliability and high quality. We have been manufacturing our products from the special energy-saving glass of the Belgian manufacturer Saint-Gobain, which has been producing the best glass for several hundred years. We fill each double-glazed window with argon and this increases the energy-saving qualities of your windows and sliding doors. High energy saving options will help you significantly reduce heating costs and ensure constant comfort.

If you’re installing a sliding door or large window, we recommend tempered or triplex glass. We independently temper our glasses in order to make them safer and we ourselves make triplex. This is a great way to make it durable and safe. Triplex technology has been used in the aircraft industry for several decades and has proven itself perfectly. Such glasses reliably protect your room from vandalism and protect your loved ones from shards.

Tempered Glass by Saint-Gobain

We recommend tempered glass as the most prudent solution, adhering to all necessary European and global standards. Saint-Gobain, a world leader in producing quality glass, stands behind this recommendation.

Protector BR Bullet-Resistant in accordance

A glazing is bullet-resistant if it hinders the passage of bullets. The DIN EN 1063 differentiates between “non-splintering” glazing (NS) and types with fragment issue (S). Non-splintering glazings is predominantly used in cases where persons spend their time in close proximity to the glass.

Protect P-A /P-B /BR /D in accordance with DIN

Impact, bullet and blast-resistant types

Protect with alarm wire

Besides the optimum burglar-resistant characteristics of SGG STADIP PROTECTOR laminated glass, further protection is optained by providing the panes with alarm systems.

Protect P-BR Bullet-Resistant in accordance

We recommend tempered glass as the most prudent solution, adhering to all necessary European and global standards. For understanding the specific level of protective glass required, we suggest referring to standards for protective glass.

Protect with SGG SECURIT

Alarm system with wire loop burnt into SGG SECURIT. An electrically conducting wire loop is burnt into the inside top corner of a SGG SECURIT pane. The loop is connected to the alarm system. If the glass is cracked, the wire is torn and an alarm is set off.

SGG STADIP® PROTECT – Saint-Gobain Glass

SGG STADIP PROTECTOR

SGG STADIP PROTECTOR is a special laminated safety glass, which offers security against attack. It is executable in different resistance classes.

Guardian Glass

Guardian Select Sunguard Fabricator for Heat Treatment in accordance with “EN 12150”, Laminated & Insulated Glass Unit Fabrication of Sunguard High Performance Products.

BCI

All glass recommended by Saint-Gobain adheres to the necessary European and global standards. As a world leader in quality glass production, this recommendation carries exceptional weight.

If you have questions about our windows, check out our page of frequently asked questions on the windows for answers.

Standard or frequently encountered window sizes:

Standard PVC window height: 450 mm, 600 mm, 1050 mm, 1200 mm, 1350 mm and 1500 mm.
The width of the NIP window can be more complex. PVC frames were originally made for bricks 215 mm long. Despite the fact that we usually use smaller bricks, the dimensions of the NPVX windows were also made for bricks 300 mm long in accordance with the EU directive.
Standard PVC window width: 488 mm, 630 mm, 915 mm, 1200 mm and 1770 mm.
But we are ready to make for you windows of absolutely any size that will be limited only by technological or design features.

Energy saving:

All our windows have an energy rating of A +, or A + + and you will not find the best anywhere else. This means that they can significantly reduce your heating bills.

Make your doors, windows and winter corner more energy:

Make your doors, windows and winter corner more energy efficient and this will reduce your electricity bills and reduce the carbon footprint. Learn how to reduce the amount of heat lost and how to find an authoritative installer.
Energy-efficient glazing covers both double and triple glazing. These are windows with two or more glasses in a sealed block, which is filled with Argon gas. You can also increase the energy efficiency of your home by installing secondary glazing or even using heavy curtains. The availability of energy-efficient windows can help reduce carbon footprint and electricity bills.

The benefits of energy-efficient windows include:

Installing energy-efficient glazing will significantly reduce the cost of heating your home in the cold. Sometimes savings can be up to 30% of current heating costs.
In summer, especially if your windows are south oriented, this will reduce heat inflows and relieve you of the need to install an expensive air conditioning system. Any additional energy efficiency efforts further improve the soundproofing properties of the windows.

Strength of construction and anti-vandal features.

Our windows comply with European standards in terms of strength, performance and weather resistance, and they are carefully tested – and above industry standards. But if necessary, we can install additional elements for some windows. It can be special reinforced elements of locks, frame structures, shockproof tempered glass or triplex.

A feature of replacing windows if you live in an old or historical house:

A feature of replacing windows if you live in an old or historical house that is of historical or architectural value.
Before replacing the windows, check in the local architecture planning department if any of the following applies to your property:
– Do you live in the protected area.
– You have an order under Article 4 for your property, which deprives you of the right to permitted development.
– You live in an old guarded building.

Some technological aspects related to the dismantling of old windows:

Most people have double or triple glazing set by a professional. Some capable people can independently install some secondary glazing systems, but only a professional must dismantle old windows and install new windows. In addition, it is important to ensure timely removal of construction waste, taking into account all requirements for safety and environmental protection.

How to measure the location for installing the window.

– Measure your window outside the property.
– Measure the brick opening in 3 places both in width and in height.
– Of the 3 dimensions, use the smallest and subtract approximately 10 mm, this is your order size.
– Always measure in millimeters ( mm ).
– Height measurements should be made at the bottom of any existing removable part, such as a window sludge or window ebb.
– Make sure that you measure the distance from brick to brick and no other elements such as a window stitch or window stitch or plaster prevent you from taking measurements.
– Enter the sizes in the list for measurements, which you will find below on our website.
