Advantages of the IzoKlass window

Savings

The intelligent design of the profile structure contributes to an improved stability of the PVC joinery. The windows are bigger, they have a remarkable static, and the solar energy is used under optimal conditions, helping reduce the energy costs of the dwelling. The construction depth allows the uptake of up to 3 sheets of glass with enhanced thermal insulation properties. Save energy simply and smartly!

Median sealing gasket

The third sealing in the profile improves the thermal insulation, the tightness of the closure, the safety of the window and reduces the impact of noise pollution. A safe and quiet home!

Safety and protection

The profile is reinforced with galvanized steel stiffeners. Standard equipment is made with German Winkhaus hardware, with high burglar resistance. Optionally hardware can be selected up to the RC2 safety class, with parallel opening (3D) or concealed hinges, for a great design. The windows are robust and provide a high degree of home security

Certified quality

Izotec windows are regularly inspected and certified by the most important European institute in the field: IFT – the Institute for Window Engineering of Rosenheim, Germany. The quality of materials and the modern production equipment contribute to these performances..

Health and comfort

The PVC profile produced in Germany does not contain lead and is environmentally friendly. Besides, Kommerling is the first leading manufacturer who introduced in the production process “green” stabilizers based on calcium and zinc, thus showing its care for environmental protection. The system is available in standard colours or wood décor veneer with a natural touch and can be easily used for new constructions and renovations.
