Safety

Because of the construction quality and the strength of the material, our products meet high safety standards. Aside from the steel reinforcements in the frame, they also feature multi-layer glass panels. Also, through the combination of various glass panel properties and profile characteristics, we can adjust the safety features to the personal requests of every client.

Joinery maintenance

ALU doors and windows should occasionally be wiped using a damp cloth and warm water. We do not recommend using coarse sponges and wire sponges, or cleaning agents of any kind. Regularly remove dust and other residue from the profiles, fittings, gaskets, and from the edges of the profiles.

Fittings

Fittings enable the joinery to open and close, and according to their method of operation we have: casement, tilt, turn and tilt, slide, turn and slide, lift and slide, fold, etc. Fittings have a crucial effect on the reliable long-term function of windows, but also on the level of safety, or burglary protection.

Glass

Aside from the ALU profile, the insulation properties of ALU windows also depend on the glazing method. Lately, with increased awareness and necessity to save energy, there is a higher representation of triple-layer 44 mm thick glass panes, with the 4-16-4-16-4 composition, low-e coating, and gas fills. At Iveta, we produce the glass panes ourselves and we are able to fully control the quality of the final product and reduce the production and delivery time.

Insulation

Windows and doors are an important insulation element of every building. The combination of insulation glass, high quality Veka synthetic profiles, and the sophisticated multi-chamber manufacturing technology enables significant energy savings. In old buildings, more than a third of thermal energy loss (almost 40%) is caused by old windows and doors. When considering the rising cost of heating fuel that represents an increasing burden on the household budget, and the fact that 78% of the yearly energy consumption in a household is for heating, thermal insulation is becoming more and more important.

Handles

Iveta offers several types of safety handles for windows. We are offering window handles with safety systems that are activated by the handle going from the open position, through the “tilt” position, to the closed position, which then activates the locking mechanism and prevents the burglar from entering easily. There are also systems that have a locking mechanism inside the handle which uses a key. The key can be on the front of the handle or on the rosette. The level of safety depends on the internal mechanism of the handle. The level of safety depends on the strength that the handle can withstand when there is an attempt to pull it out of the rosette. Aside from the standard handles, we offer handles from the manufacturer Hoppe.
