No apartment or private house can be imagined without a front door. It not only protects us from uninvited guests, but is also able to keep warm. Today I want to focus on individual buildings. This is where the problems arise. Let's look at the doors with a thermal break. Consider their features and specifications.
Know-how on the doorstep
To begin with, it is worth telling what a thermal break is, and for this you need to remember the law of physics. It says: all materials are able to give and receive heat. This transfer is made from a warm region to a cold one. Steel entrance groups are no exception. When it is cold outside and the house is warm, heat transfer begins, and here the cold gradually penetrates into the room.
To somehow reduce the process of heat transfer, they resort to using a thermal break. Simply put, this is an element of the inside of the door, which is characterized by low thermal conductivity.
You might never see thermal break doors, but you experience this effect every day, for example:
- put on a kitchenpotholder before picking up something hot;
- put on warm clothes before going out on a snowy street.
Application
This effect in the manufacture of entrance doors began to be used not so long ago. Prior to that, it was replaced by a second partition. To be more precise, it was an additional door that created the very barrier and absorbed all the cold air. This method has not gone anywhere, but just to replace the bulky structures, the installation of which takes a lot of effort, time and money, an alternative has come. New products look aesthetically pleasing and hold heat well.
Production
Surely you will be interested to know what a thermal break door consists of. Reviews show that more and more often it is these models that become sales leaders. And if you look inside it, you can see the following:
- Outer metal sheet with decor.
- Cork fiber.
- Polyurethane foam.
- Folgoisolon.
- Styrofoam.
- Inner metal sheet.
The thermal break in this design is foil isolon, which is laid in the middle of the inner space of the door leaf.
Certification
When you go to a store, don't buy the first door you see. It's time to study all the technical documentation. High-quality doors must be manufactured in accordance with GOST 31173. This information must be provided to you by the sales assistant. And also for a product of this qualityyou must provide additional information. Namely:
- Documents for door testing. All certified products must have such conclusions. In them you will find all the test results in the field of sound insulation, heat dissipation, reliability and air circulation. The total number of checks should be about 8 points.
- Separate act of testing heat-conducting properties. The door passes the test, during which the temperature balance must be maintained: on one side of the product, the temperature should be about -20 degrees, on the other - +20. There can be no heat leaks, this is required by the standards.
If the manufacturer has all the documents available, then you can safely purchase such a door with a thermal break.
Features
Now we should tell you about the merits of such an entrance door. These include:
- minimized heat loss;
- reduced energy costs;
- door can be used for a long time.
Also, I would also like to note that there are no shortcomings in such a door. Is only a high cost, but its quality is worth it. The price for such a product starts from 22,000 rubles.
Additional materials
We are getting acquainted with such an interesting product, without which no building can be imagined. What does a thermal break door look like? The photo will show you in more detail what a quality product looks like.
When listing heat-insulating materials, we did not mentionfiberglass. With it, the door is cheaper. But at the slightest fire, fiberglass burns strongly and releases toxic substances.
View matters
All entrance doors with a thermal break have low thermal conductivity and original design. Reviews of people speak about the popularity of such models. Here's what users say about them:
- Great value for money.
- Doors perform well even in severe frosts.
But buyers also identified major flaws:
- High cost.
- Expensive door installation and maintenance services.
- The installation is often done by incompetent workers, after which the thermal break effect is not felt.
And of course, attention should be paid not only to internal materials, but also to external ones. It all depends on your preferences and wallet capabilities. You can make an exclusive design that will emphasize the style of your home. Door trim on the inside can be made of wood, chipboard or laminate board.
Installation
Be sure the door must fit exactly under your opening. To do this, you need to contact the help of a measurer, but you can do this procedure yourself. And then everything is simple. Order the door of the size you need and wait for the installer.
Advice! Do-it-yourself entrance door with a thermal break should not be installed. This is especially true when it is necessary to do this at the street-house boundary. All work mustbe carried out by specialists to obtain a perfect tightness.
Now you know that thermal break doors are the best option for a private house that does not have a vestibule. You can forget about the accumulated condensate and constant drafts forever.
