Burglary resistance classes

In a building, whether residential or public, the most common and easiest way to break in is by breaking through windows and doors. When burglary protection is not used, in the production of joinery, thieves need little time and effort.

According to a pan-European standard, there are six types of burglary resistance classes – RC1, RC2, RC3, RC4, RC5 or RC6. They are also found as WK1, WK2, WK3, WK4, WK5 and WK6. The classification is based on experiments with static and dynamic loads on components (windows, doors and suspended facades), as well as on the basis of simulated theft attempts, which compare the time and tools needed by the thief to overcome the obstacle.

Schüco, Jansen, Reynaers, Forster and Rehau products offer doors, windows and doors with burglary resistance classes up to RC3.



Shelters, pergolas, penthouses and glazing

More and more often clients require functionally and aesthetical solutions for glazing balconies, verandas, terraces, as well as building sheds in a relaxation area, barbecue and others. There are a number of options that InnovaStyle offers.



An option for SKYMATIK aluminum pergolas SKYMATIK. In addition to effective sun protection, they offer many additional accessories – built-in blinds; glazing with sliding windows; embedding music and various types of lighting; anti-snow retention system; remote control and smartphone; rain sensors; snow and wind; automatic braking system for obstacles, as well as a wide range of colors. There is also the possibility of several colors in one pergola. They are designed to withstand loads up to 300 kg / sq.m, and this is achieved without an additional option against snow retention.





WINTER GARDENS Schüco and Reynaers

Another option are the system conservatories of Schüco and Reynaers, which in essence resemble an aluminum suspended facade, but allow geometric shapes in more planes. Like the suspended facade, different types of windows and doors can be built into their construction. They have excellent heat and sound insulation properties.



Windows and facades – types, advantages and disadvantages

Frequently asked questions are: “What exactly is the difference between windows and a facade?”; “What are the types of windows and facades ?”; “What are the advantages and disadvantages of window frames and facades over each other?”; “What to look for and how to choose windows or facades ?” , Etc.



The most significant difference between the windows and the facade is that the windowsare placed inside the opening in which it steps, and thefacade is attached to the floor, wall or ceiling (depending on the shape of the building) by means of cantilever slats. in this way it stands in front of the opening itself.



Aluminum facades are mainly divided into two varieties – COLUMN-BEAM (known from the German language in the industry as pfosten-crossbar) and ELEMENT. The most significant differences start from the installation itself – with the column-beam facade , the columns for the supporting structure of the building are installed first, after which the horizontal elements (crossbars) are installed. This type of aluminum facade is more widespread of the two. In the case of the element facade, each module is prefabricated in a workshop, and the installation takes place module by module. It is suitable for buildings with a large number of repeatable elements; installation takes less time, but is more expensive. Due to the above differences, different types of profiles and components are used for the implementation of the two types of facades.




The column-beam facade is mainly of two types – cap and with silicone joint. In the cap, in the outer part of the building there are visible profiles of aluminum – “caps”. On the facade with a silicone joint, instead of aluminum profiles there are thin silicone seals. There is a third option – a combination of the first two.




Basically, the windows are divided into aluminum, PVC and steel. The advantage of PVC windows over aluminum is the price (with less money are achieved similar heat and sound insulation characteristics). The disadvantage is the smaller variety of types of opening and accessories for installation, as well as the limitations in the maximum sizes. Steel is the most expensive, but surpasses the other two in all structural and functional qualities. Some of the most common window configurations and openings are shown in the image above:

  1. Single-leaf window with opening inwards
  2. Single-sash window with opening to the outside
  3. Double-sash window with divider
  4. Single-sash window with offset vertical axis
  5. Window type valve
  6. Lift and slide door
  7. Single-leaf window with upper hinges
  8. Single-leaf window with lower hinges
  9. Double-sash window with flying divider
  10. Single-sash window with offset horizontal axis
  11. Entrance door
  12. Accordion type window

You can take a closer look at the different types of opening here.




The main advantage of the aluminum facade over the windows is the ability to glaze huge areas. With facade , the visions are achieved in which the whole building looks like glass. Unlike, windows however the aluminum facade itself does not offer opportunities for opening. Openable elements an aluminum facade are achieved by embedding the familiar elements of the windows in it.







СПЕЦИФИЧНИ ЖЕЛАНИЯ ЗА АРХИТЕКТУРА И ДИЗАЙН – например големи размери на остъклените елементи, или нетрадиционни геомтрични форми.

ИЗИСКВАНИЯ ЗА ТОПЛО И ШУМОИЗОЛАЦИЯ – един от основните фактори, влияещи при избор. Географското разположение и предназначението на сградата са водещ мотив за избор на конкретна система дограма или окачена фасада.

ВЗЛОМОУСТОЙЧИВОСТ – понякога естеството на сградата налага висок клас на взломоустойчивост, понякога е желание на клиента. И в двата случая ИноваСтил може да предложи алтернативи от продуктите на Шуко, Рейнърс и Рехау.

ПОЖАРОУСТОЙЧИВОСТ – при нужда се прибягва до специализирано разработени за целта пожароустойчиви системи.

ЕКСТРИ И АКСЕСОАРИ – допълнителни оборудвания като скрит обков, автоматизирано отваряне, вентилационни системи, сензори за аларма и други.

БЮДЖЕТ – балансът цена-качество често е определящ.

Types of glazing units

Types of glazing units

Although the profile is the base of the window/door, the greatest heat and noise transmission takes place through the glazing, as it has the largest area. That is why the double-glazed window is a detail that should not be neglected. When choosing a glazing unit, it is important to take into account several things that will contribute to our correct assessment:

  • the location of the building and the climatic conditions in the area
  • the orientation of the façade
  • time zone for use of the building (for buildings intended for use only in summer)
  • the opportunity to invest in energy-saving glass, which would lead to a significant reduction in heating and cooling costs

The glazing unit is two or more sheets of glass that are hermetically sealed to each other using a special glue and a spacer. In this way, a hermetically sealed air space is formed between the panes, which is an insulator. The glazing is 80-90% of the window area, which makes it decisive for the heat and sound insulation properties of any window system!

Glass – standard

  • Glass thickness 24 mm,
  • Two transparent float glasses of 4 mm each,
  • Spacer 16 mm, thermal insulation 2.8 W / m2K ,
  • Noise isolation 32 dB, light transmission 91%


Glass – reinforced

  • Thickness – 26 mm
  • Two glasses – 5 or 6 mm on the outside, 4 mm on the inside
  • Spacer 16 mm,
  • Thermal insulation – 2.8 W / m2K
  • Good strength at large sizes
  • Increased noise insulation


Glassware – with low emission glass

  • Glass thickness 24 mm, low emission glass and clear glass 4 mm
  • Spacer 16 mm
  • Thermal insulation 1.9 W / m2K
  • Noise isolation 32 dB
  • Daylight transmission 91%
  • The low-emission glass is coated with an ionized layer of precious metals, which reflects the long-wave spectrum of the infrared rays from the sun’s rays and heating or air conditioning appliances.


Glass package – with tinted glass

  • Thickness – 24 mm
  • Two glasses – externally 4 mm tinted, internally 4 mm transparent
  • Spacer 16 mm,
  • Thermal insulation – 2.8 W / m2K
  • There are variants of tinted glass


Glassware – with reflective / stopsol / glass

  • One colorless float glass with a glass thickness of 4 mm, one reflective glass /green, blue, gray, brown/ with a glass thickness of 4 mm
  • Spacer 16 mm
  • Thermal insulation – 2.7 W / m2.K
  • Noise isolation – 32 dB
  • Daylight penetration – 40% to 60%

Stopsol glass has a special coating of metal oxides, applied with pyrolysis during its production. Stopsol glass is designed for additional protection of the premises from ultraviolet solar radiation and creates the effect of a mirror surface. Stopsol glass has a lasting reflection, perfect uniformity and consistency over time and a hard coating, resistant to scratches and stains.
