Contemporary window joinery must combine multiple qualities: high energy efficiency, aesthetics, durability, and user comfort. The Ideal 4000 system, now available in Bertrand’s offer, addresses all these needs – it’s a solution designed for modern construction that doesn’t compromise.

What makes the Ideal 4000 system stand out?

 

Versatility and modern appearance


Ideal 4000 is a PVC system that works perfectly in single-family homes as well as multi-family or commercial buildings. Clean lines and the classic profile design offer great flexibility in arrangement – the windows match both modern and more traditional façades.

Thanks to the option of choosing between straight or rounded sashes, the windows can be tailored to individual preferences.

  • CLASSIC LINE – NON-FLUSH

  • SEMI-FLUSH VARIANT

  • ROUND LINE – SEMI-FLUSH

 

 

Durability and security


The robust profile construction with a 70 mm installation depth and glazing chamber width of up to 48 mm ensures excellent stability and resistance to mechanical damage. Steel reinforcements in frames and sashes increase the rigidity of the window, which is particularly important for larger glazing.

The system also allows for the use of modern hardware with anti-burglary locking points, significantly improving safety levels.

Energy efficiency and comfort

Nowadays, windows are inseparable from the concept of energy saving. Ideal 4000 offers excellent insulation properties:

  • heat transfer coefficient (Uw) suitable for energy-efficient construction,

  • possibility to install double or triple glazing units,

  • excellent airtightness thanks to two independent seals – external and internal.

 

All of this results in reduced heat loss in winter and protection from overheating in summer. This directly translates into increased comfort for residents and lower heating or air conditioning costs.

Rich colours and style

Thanks to a wide range of decorative foils (including wood-like and metallic finishes), the Ideal 4000 system allows you to create windows that harmonize with the façade, interior, and the user’s personal style.

Variants with aluminum cladding (Aluskin) are also available, combining the benefits of PVC with the modern look of aluminum.

Technical capabilities and configuration

The Ideal 4000 system also offers:

  • various opening types: tilt, turn, tilt-and-turn, parallel sliding,

  • low-threshold options for balcony doors – ideal for elderly people or children,

  • the possibility of creating large glazed areas while maintaining stability.

 

 

Ideal 4000 is a system that combines modern technologies with classic aesthetics. With it, you get: energy-efficient and secure windows, long-term comfort of use, and design flexibility to suit any building style.

If you’re looking for windows that will meet the expectations of both the investor and the architect – Ideal 4000 is a choice that truly pays off.
