Doors with thermal fracture: design advantages and choice of model

Without an entrance door, you can not imagine any apartment or private house. It not only protects us from uninvited guests, but also is able to keep warm. Today I want to focus on individual buildings. It is here that problems arise. Let's look at the door with thermo rupture. Let's consider their features and technical characteristics.

Know-how on the doorstep

To begin with, it is worthwhile to tell what the thermal break is, and for this you need to remember the law of physics. It says: all materials are capable of giving and receiving heat. This transfer is made from a warm area to a cold one. Steel input groups are no exception. When the outside is cold and the house is warm, heat emission begins, and then the cold gradually penetrates into the room.

To somehow reduce the heat transfer process, resort to thermal fracturing. Simply put, this is an element of the inside of the door, which has a low thermal conductivity.

You could never see the door with a thermo rupture, but with this effect you come across daily, for example:

• Put the kitchen pothook on your hand before taking something hot;
• Put on warm clothes before going out onto the snow-covered street.

Application

This effect in the manufacture of entrance doors began to be used not so long ago. Before that, it was replaced by a second partition. And more precisely, it was an additional door that created that very barrier and absorbed all the cold air. This method has not gone anywhere, but simply to replace cumbersome structures, the installation of which takes a lot of energy, time and money, an alternative has come. New products look aesthetically pleasing and keep heat well.

Manufacturing

Surely you will find it interesting to know what the thermo-interrupted door consists of. The reviews show that more and more often such models become the leaders of sales. And if you look inside it, you can see the following:

1. Outer sheet metal with decor.
2. Cork fiber.
3. Polyurethane foam.
4. Folgoisolone.
5. Styrofoam.
6. Internal metal sheet.

A thermal break in such a construction is the foil-isolone, which is used to lay the middle of the interior space of the door leaf.

Certification

When you come to the store, do not buy the first door you got. It's time to study all the technical documentation. Quality doors should be manufactured in accordance with GOST 31173. This information you need to provide a sales consultant. And also for the goods of this quality you need to provide additional information. Namely:

1. Documents for the test of the door. All certified products must have similar conclusions. In them you will find all the test results in the field of noise insulation, heat transfer, reliability and air circulation. The total number of inspections should be about 8 points.
2. A separate act of testing the thermal conductivity properties. The door passes the test, during which the balance of temperatures should be maintained: on one side of the product the temperature should be about -20 degrees, on the other - +20. There can not be any heat leakage, standards require it.

If the manufacturer has available all the documents, then such a door with thermal fusing can be safely purchased.

Features

Now you should tell you about the advantages of such an entrance door. This includes:

• Minimized heat loss;
• Reduced energy costs;
• The door can be operated for a long time.

Also, I would like to add that there are no shortcomings in such a door. Is it only high cost, but its quality is worth it. The price for such a product starts from 22,000 rubles.

Additional materials

We are acquainted with such an interesting product, without which no building can be imagined. What does the thermo-interrupted door look like? The photo will show you in more detail what a quality product looks like.

Enumerating thermal insulation materials, we did not mention fiberglass. With him, the door is cheaper. But with the slightest fire, fiberglass burns strongly and releases toxic substances.

The species is important

Low thermal conductivity and original design have all the doors with thermal fusing. Reviews of people speak about the popularity of such models. Here's what users say about them:

1. Excellent value for money and quality.
2. Doors show themselves well even in severe frosts.

But buyers identified and major shortcomings:

1. High price.
2. Expensive door installation and maintenance services.
3. Often installation is made by incompetent workers, after which the effect of thermal fracturing is not felt.

And of course, attention should be paid not only to internal materials, but also external. Here everything depends on your preferences and the possibilities of the wallet. You can make an exclusive design that will emphasize the style of your house. The interior finish of the door can be made of wood, chipboard or laminate board.

Installation

Be sure the door should exactly fit your doorway. To do this, you need to turn to the help of the gauger, but you can also do this yourself. And then everything is simple. Order the door of the size you need and wait for the installation wizard.

Advice! It is not necessary to install the entrance door with thermo rupture by one's own hands. Especially it concerns the situation when it is necessary to do this on the border "street-house". All work should be carried out by specialists in order to obtain an ideal tightness.

Now you know that thermo-interrupt doors are the best option for a private house that does not have a vestibule. You can always forget about the accumulated condensate and permanent drafts.
