4 causes fogging door: how to eliminate fogging and freezing doors

Owners of private homes in the cold season may be faced with the problem of condensation on the inside of the front door, which in the cold freezes to form frost.

Moisture greatly increases wear door structure: slope leads to deformation and web rust, as well as mold and mildew.

Reasons for fogging doors

Blame a significant temperature difference between indoors and outdoors. The heated room air passes into the condensate in contact with the ice door.

This problem occurs primarily on metal doors, since the metal is an excellent heat conductor.

Wooden doors too prone to fogging, since they have metallic elements conducting cold. Condensation occurs for the following reasons:

1. Poor insulation: lack of insulation, when the cavities in the web does not filled, it insufficient and uneven distribution;

2. High humidity in the room;

3. Violation door installation technology: a wrong internal flanks, the gap between the box and the web, even if they are not more than 2.1 mm;

4. The presence of so-called "cold bridges" - metal parts, which pass through the fabric: the castle, eye, loop, rib frame rigidity.

Remedy fogging and freezing

When the condensation on the front door is necessary to take measures aimed at maximum reduction of temperature difference:

• warm door. Put insulation into the interior or attached on the outside, for example, glue foam. In addition, the perimeter can be placed insulation tape hindering the cold. It requires securely insulate all metal elements derived into the room, including a special cover plate keyhole;

• seal seams between the frame and the door using air gun and foam, set along the perimeter of the rubber gasket for a tight fit of the door frame to the slope;

• the door itself or attached to the panel it is possible to cover special compositions, Retaining heat;

• attach veranda or install a second outer door of the timber;

• In extreme cold near the door can be put heating instruments.

The appearance of moisture or frost means increased energy losses because of the room quickly leaves accumulated heat but also leads to a rapid deterioration doors and boxes. The problem must be addressed immediately to the door structure ahead of time is not out of order.
