Perfect Design casement

IDEAL 4000 casement is an example of a group of outward opening window systems characterized by a flat rebate with one or two diagonal planes. Windows in these systems are installed equally willingly in broad residential construction, as well as in market segments related to public tenders and architectural services. The advantage of this type of systems, especially those characterized by a single oblique rebate surface, is definitely faster and easier cleaning.

Two versions of window sash:

Classic line

Round line

A wide range of options for adjusting the appearance of the windows – according to your preferences

Choose the version that better suits the look of your home.

For white windows, you can also choose the color of the glazing seal: black, or light gray.

Standard glazing package

Our doors are equipped with a tripe plane glass that is connected by three spacing frames, two of which are covered with Low-E coatings

The glass type strongly depends on the measurements of the whole door configuration. Please have a look at examples:

  • 4LE/18Ar/4/18Ar/4LE
  • 4th/16Ar/4/16Ar/4th

Safety glass

For an extra charge we have in our offer a safety glass option.

The safety glass consists of two glass panes joined together with a laminated PVB foil. This solution is used in for instance the windscreens of passenger cars because of its shatterproof function and strength. Additionally, it provides better sound insulation.

Sample glass package with a safety glass:

  • VSG 33.1 LE/ 18 Ar/4mm/18 Ar/4mm LE

P4 glass – increased resistance to damage / burglary

P4 glass type with higher resistance to damage e.g. VSG 44.4 where glass panes are connected with 4 layers of protective foils.

The strength of P4 glass is confirmed in laboratory tests. During the tests, the glass must withstand a three-time impact with a 4.11 kg steel ball dropped from a height of 9 m. This type of glass is characterised by the highest resistance to manual attack for instance with a hammer weighing several kilograms.

Sample package with a safety glass:

  • VSG 44.4 LE/ 16Ar/ 4mm/ 16Ar/ 4mm LE

Warm spacer frames

A spacer frame is the basic element of joining the space between the panes in a glass. It is normally filled with 90% argon which is a non-toxic, insulating dense type of gas and 10% air. It allows to obtain a heat transfer coefficient of up to Ug = 0.4 W/m²K.

Warm, Swisspacer Ultimate spacers (available in 6 colors) are used as standard in our glazed units. They are recommended for energy-saving construction thanks to a significant reduction in the heat transfer coefficient. Due to the extremely thin gaps between the panes Krypton is used which is a gas that performs best as an insulator when used in such configurations.


There is a huge range of choices in glazing, for instance: energy-saving, sound-absorbing, safety, anti-burglary and solar glass.

Solar glass
This category includes several types of special-purpose glazing designed to reduce the effect of the sun in interiors – both in terms of heat transfer and excessive light penetration. The most common solutions are milk glass, glass with one-way mirror effect as well as bronze reflex glass.


Thermal insulating glass – energy efficient
This type of glazing is designed to provide the best possible thermal insulation of a room, which is especially important in temperate climates, where there are significant temperature differences between seasons. Thermal insulating glazing is covered with an extremely thin layer of precious metals, so in winter it minimizes heat loss from the room, while in summer it prevents excessive heating.

Sound-absorbing glazing
Sound-absorbing glazing provides excellent sound insulation along with comfort for people in rooms whose windows face, for example, busy streets (low-frequency sounds) or children’s playgrounds (high-frequency sounds). The effect of sound-absorbing glass is related to the thickness of the glass – the thicker the glass, the better it protects against outside noise. Such glazing can be made of ordinary glass, tempered glass or laminated glass with a film. The space between the layers of glass is filled with heavy gases.

Safety glass
Safety glass is usually layered glass or glass made of laminated or tempered glass that does not shatter into small fragments when broken. This type of glazing primarily provides protection against injury from glass shards.

Anti-burglary glass
Burglar-proof glass, as the name suggests, protects windows from a burglary. Mostly they are layered glass, made of two layers of glass and between 2 to 4 layers of PVB film. The film strengthens the structure of the glass – the more layers of film, the more resistant the glass is to mechanical damage. We can divide anti-burglary glass into 8 classes: P1A, P2A, P3A, P4A, P5A, P6B, P7B and P8B. The strength of glazing in each class varies significantly. For example, according to the standard, glazing of the P3A class can replace the grid made of Ø10 steel wire, with meshes up to 150 mm, while glazing of the P8B class replaces the grid made of steel bars with diameters up to Ø16.


The standard color of IDEAL 4000 windows is white (natural PVC). However, special veneers can be applied to them, which decorate and add character. Depending on your needs, veneers can be applied on one side (outside or inside), or on both sides.

The color palette is rich and allows customization for any project.
