Secure Hardware System

Thanks to wireless sensors, no modifications are required in your home and the entire system can be installed in just half an hour.

KVCPEN series has optional security window, door, sliding and parallel sliding options. In order for a window to be secure, many factors must come together. First of all, a system consisting of strong profiles should be selected and this system should be reinforced with security hardware, locking handles, reinforced support plates and secure glazing.

Air holds a certain amount of water as vapor at each temperature. If this amount increases or the temperature decreases, the vapor condenses as water and sweat occur. If the water vapor in the air is below the condensation temperature of the joinery and glass surfaces, this sweat is evident on the joinery and glass.

First of all, we must reduce the water vapor in the air. The most significant sources of water vapor are bathrooms and kitchens.
Doors of kitchens and bathrooms should always be kept closed, bathrooms should be ventilated through ventilation windows, and kitchens should be ventilated through aspirators and chimneys.

Laundry should not be dried inside the house.

If there are other sources of moisture in the house, ventilation time should be increased.

The surest solution to reduce sweating is to ventilate our homes. This ventilation should continue periodically until the fogging (sweating) on the glass surface disappears.

After installing PVC windows, plaster and whitewash modifications are made, if any. The protective tape is removed, and the tape is exposed to heat and sunlight for a long time, which will cause it to boil to the profile surface, making it difficult to remove.

Otherwise, it is more appropriate to apply a thin oil heated up to 55ºC on the tape surface, leave it for 4-5 hours, and then remove it.

Materials such as paint and mortar adhered to the profiles should be carefully cleaned immediately but without scraping.

Care should be taken to ensure that the detergents used for cleaning are not excessively particulate, and liquid or cream ones should be preferred. Contact with metal-equipped water or soap should be avoided.

PVC systems should not be cleaned with solvents or bleach.

To prevent sweat on the surface of building elements;

The temperature inside should be around 20-22ºC.
The parts of the building where water is used intensively, such as bathroom-WC, should be ventilated with windows.
Water vapor released during cooking should be removed with aspirators on the stove.
It should be ventilated at least 4-5 times a day.
