An important role in creating a comfortable living in the apartment is played by the entrance doors. The struggle "for degrees" on a winter night evenings provokes a reaction, and we begin to frantically insulate the front door. How to insulate the door with your own hands, and, most importantly, what?

Farewell, doors covered with dermatitis
The times when the entrance wooden door was insulated with dermatome, long gone. In the old fashion, some people are still trying to try to insulate the door in such an antiquated way. However, whether the dermatitis in the country is over, or whether the inner voice suggests that this way the door can not be insulated.
Then how to insulate the wooden door? Today, the construction industry offers quite good materials that have sound and heat insulation properties. Therefore, we turn our attention to new materials, which can be safely called a heater for the entrance door.
Insulation for entrance door
The vast majority of the entrance doors, especially those made by the manufacturer, are equipped with an internal insulation. For insulation of doors use the following materials:
• mineral wool
• Corrugated cardboard
• Styrofoam
• foam rubber.
As you can see, felt, skin and dermatitis here already does not smell. Moreover, the old materials, absorbing moisture over time, can not cope with the assigned role of the heat insulator. Therefore, instead of them, you can successfully use foam rubber and foam. Such materials are easy to install, and for ease of installation, heaters are provided with an adhesive layer.
To insulate the entrance doors, in particular metal doors, a "honeycomb filling" is used, which is embedded in the door leaf.
The characteristic method of laying the filler provides the best thermal insulation. Mineral wool, commonly used as a heater, has a fibrous structure, because it is made from mineral raw materials.
Due to its origin, mineral wool is fully responsible for the tasks and rhetorical question: "A heater for doors, which is better?". Ecologically clean product - insulation has high mechanical and heat-insulating properties, prolonging the service life of the entrance door.
The required rigidity of the construction of the entrance door is provided by the filler corrugated board. The rigid filler used for steel doors has considerable mechanical resistance in the vertical and horizontal directions. The design of the corrugated cardboard is responsible for the strength of the filler of the entrance door. Corrugated cardboard has low weight and cheapness.
Styrofoam has established itself as a heater for entrance doors, for a long time. The foam has a porous structure, low density and high sound and heat insulation characteristics. The practice of door insulation is now practically unthinkable without the use of polystyrene foam. Simplicity of installation and minimum costs allow to make insulation by foam independently any door leaves, starting from the entrance doors, and ending with the doors to the balcony or loggia.
Polyfoam can be used to insulate even wooden doors, however, it is recommended to decorate the top layer of insulation with MDF panels or plastic sheets. It is cheap and affordable for those who decided to insulate the entrance wooden door with their own hands. From insulated steel doors from the manufacturer, the doors of the wooden entrance insulated will differ in weight design.
As a filler and a heater can be used foamed polyurethane foam, which is obtained in the manufacture of foaming agents. The obvious advantages of polyurethane foam are:
• Resistance to negative influences
• Improved insulating properties
• light weight
• simple installation
• Eco-friendliness.
This type of filler for the entrance doors has a convenient design for installation - foam plates. Plates provide heat insulation and waterproofing on a relatively large area of contact with the surface of the door. To fully seal the area of the insulated door leaf, the joints between the plates are sealed with a silicone sealant. This material is least affected by mechanical forces - compressive and tensile.
In practice, this will mean a longer service life of the front door.
Excellent has a heater isolon. Isolon is an elastic foam polyethylene, with an expanded range of thicknesses and densities. Are you skeptical and doubt that this film material can protect the apartment from the cold? In this case, familiarize yourself with the distinctive thermal insulation properties of the isolone.
Compared with the existing thermal insulation materials, isolon has a significant coefficient of thermal conductivity: 0.031 W / mK at an isola density of 33 kg / m3. For comparison, one centimeter of isolone can be replaced:
• 4.5 cm thick mineral wool insulation
• 4.5 cm of wooden insulation
• 1.2 cm of expanded polystyrene
• 15 cm brick masonry.
Fantastic properties of isolone are concluded in the process of processing high polymer raw materials and innovative technology.
Foamed polyethylene foam combines hydro-, noise-, vapor- and heat-insulating properties. An excellent option for a door heater with your own hands! True, this material is not cheap.
The main methods of warming the wooden entrance door
In addition to the above heaters and fillers, solve the problem of insulation of wooden doors in the following ways:
• replace the entrance wooden door with a practical metal door
• Choose a tubular seal for the door leaf
• install the second front door.
The cardinal method of warming can be called the replacement of a wooden door with a already insulated metal.
Immediately there will be a lot of problems related to the insulation of the old front door. Moreover, you can install the metal front door yourself.
The selection of a tubular sealant is recommended to be made from materials that have the quality of a self-adhesive base. The width of the seal should be chosen from the width of the gap between the door frame and the door itself.
It is recommended to pay attention to the thickness of the seal. Here it is necessary to make a small experiment: glue a piece of sealant and make sure that the entrance door is simply closed and opened. To mount a seal of this type around the perimeter of the wooden entrance door is not difficult.
Solve the problem of the thermal insulation of the entrance wooden door by installing the second door. Between the first and second doors a magnificent air cushion is formed, which will increase the thermal insulation characteristics of the wooden door.
