Rating of the best entrance doors with thermal break for 2020

Entrance doors are an indispensable element for the protection of both apartments and private houses. The most reliable option is metal, but not all of them are suitable for use in cold weather. Special devices - thermal breaks will help to solve the existing difficulties. To find out which option is suitable for a particular room, the rating of the best entrance doors with a thermal break for 2020 will help.

What is thermal break

Metal entrance doors have long proven themselves for their strength, reliability, resistance to damage, and ease of maintenance. The main problem of such products in Russian conditions is exposure to cold temperatures. Due to the fact that metal is a material with high heat conductivity, problems arise with heating the room, freezing doors.

Traditional heaters placed inside the structure are not always able to resolve the issue, because metal parts are still in contact with each other (for example, at the place of welding or fastening of the outside and inside of the box). A thermal break can correct the situation. It is a layer of material with poor heat conduction that insulates parts of the metal from each other, is placed between them, tightly fitting.

The thermal break can be of different sizes, configurations, located in different parts of the door. It can be in the form of a narrow strip, a wide part, long or short, flat or voluminous. Thermal break can be both in a single copy, and in several for 1 item. In some cases, the part can be removed by disassembling, or peeled off, in others, the desired fragment is mounted into a metal fragment even before it is bent in shape. In such a situation, you cannot remove the gap.

Why do you need a thermal break

A great difficulty in installing metal doors in Russian conditions is the high thermal conductivity of the metal. In the cold season, the outer part, which is located in the entrance or on the street, cools down a lot, while the room part heats up. As a result, the door may freeze and condensate may form. A similar situation can be observed on plastic windows.

Moisture affects the safety, technical indicators of the door itself, and also ends up inside the locks, fittings, causing damage. In addition, heat is lost in the room. As a result of the installation of insulation, the situation does not change completely. The so-called "dew point" is often simply displaced inside the door itself, because, despite the interlayer, the outer and inner parts of the doors touch each other at the point of attachment, form "cold bridges".

The solution to this difficulty is the thermal break, which insulates the outer and inner layers.This interlayer is installed in various parts of the door, usually the frame or the leaf itself, prevents contact between the outer and inner layers of metal, as a result of which each part remains at its own temperature. Also, the thermal part solves the following tasks:

• prevents the outflow of heat into the corridor (to the street);
• reduces electricity bills, because you do not have to turn on the heater (if it is possible to regulate the flow of heating separately to the apartment, it reduces the cost of it);
• the metal door does not freeze from the inside, frost does not form on it, and condensation does not form;
• locks, fittings last longer;
• has anti-corrosion treatment.

Door types

In addition to the separation options provided for all entrance doors (for example, single- or double-leaf, swing, or sliding, by metal thickness, type of locks, insulation options), models with a thermal break have their own classification. The types of such models depend on the criterion underlying the separation.

By the number of elements, there are:

• with 1 insulating insert (usually on a canvas or box);
• with 2 inserts (in the canvas and in the box);
• with a large number of thermal breaks (installed in the leaf, box, stiffeners, near door handles, etc.)

By connection:

• Bolt. It involves fastening by means of steel bolts and nuts, or rivets. Most models are equipped with this option, although in this case the contact between the external and internal metal parts remains through the steel elements (albeit on a minimal area).
• Through a thermal insert. The thermal break has no fasteners, after installing the structure of the canvas, the box, an insulating substance is poured into the necessary zones, which hardens.
• Through micro-incisions. At the junction of the outer and inner metal parts, many closely spaced holes are made using laser cutting. Thus, a reduction in the area of ​​the "cold bridges" is achieved. This method is quite rare, customer reviews note its low efficiency.

Integrity:

• thermal breaks that can be removed;
• stationary, flowing into the cavity and solidifying, or added at the stage preceding the bending of the sheet (they are one with it).

By the number of layers:

• 1;
• 2 or more interconnected.

By material:

• PVC. In the form of a thermal break, it is a cavity filled with air, or a solid part. Durable material that also has low noise and moisture permeability. Thermal conductivity depends on the type of material. Not recommended for a country house in very cold winters, it can be used for an apartment with access to the entrance or to the site, not the street.
• Izolon. This is foamed polyethylene, which has a porous-cellular structure. It can be foil on one or both sides, it is often used in combination with other materials. It has low vapor and water permeability, and is responsible for sound insulation. Thermal conductivity - 0.031-0.037 W / m * ° С.
• Expanded polystyrene. It is a polystyrene granules filled with gas, sintered together. This is a type of foam. It has low water and vapor permeability, thermal conductivity is 0.028-0.037 W / m * ° С.
• Cork (crushed, compressed tree bark for technical purposes). It has a honeycomb structure, the internal space is filled with a gaseous mixture. This structure allows for low thermal conductivity. Thermal conductivity is 0.0363-0.13 W / m * ° C. This material also provides sound insulation, waterproof, does not lose shape. Natural cork is not harmful to health.
• Wood. Natural breeds are rarely used because have a high cost. Additional moisture protection required. Thermal conductivity depends on the specific breed, on average from 0.095 to 0.4 W / m * ° C.
• Foil penofol is an inexpensive material consisting of polyethylene foam covered with aluminum foil on 1 or 2 sides. It is used more often only as an additional layer of insulation, namely as a heat insulator.Possesses low permeability to moisture, steam, sound. Flexible, requires fixation. Thermal conductivity - 0.037-0.052 W / m * ° С.
• MDF (or medium density fiberboard). It is a small wood shavings that have undergone heat treatment and gluing. Protects against heat loss, sound transmission. Less resistant to moisture than other materials (except wood). Thermal conductivity - 0.064-0.12 W / m * ° C.
• Mineral wool. A melt product of broken glass, sand, rocks or blast furnace slag. Contains clay, dolomite, limestone as impurities, formaldehyde resin as a binder for components. After melting, the viscous mass is placed in a centrifuge, where it is broken into individual fibers and covered with resins. It protects well against noise, allows steam to pass through, and requires additional waterproofing. The question of the health risks of resins and fibers remains controversial. Thermal conductivity, depending on the type, is equal to 0.035-0.07 W / m * ° C. The indicator gradually increases due to moisture penetration (by 50% over 3 years) if there is no waterproofing.

How to choose the right model

In order to choose the best doors with a thermal break, you need to focus on the following recommendations:

• models should be with several elements, at least in a box and a canvas, and even better in stiffeners, a handle, etc.;
• variants should not have eyes, other cut-in elements, because they increase the number of "cold bridges";
• preferable locks with a lever mechanism, especially those in the "pockets" that do not touch either the inner or the outer contour, or having "curtains" on the outside;
• if the material from which the gap is made does not have good moisture-repellent properties, it must be provided with additional insulation from moisture;
• foil tears additionally reflect heat;
• it is worth considering the thermal conductivity of the material, some types are more expensive and require greater thickness, while others achieve the same result in insulation at lower costs;
• options with a powder coated exterior with anti-corrosion treatment perform better;
• do not choose laser cut tears;
• it is imperative to take into account the temperature conditions recommended for operation, especially when choosing a model for a house with access to the street;
• there should be no defects, chips or other damage on the surface;
• expensive models are equipped with additional functions, for example, heated canvas, such options better cope with the purpose;
• the thickness of the metal must be at least 1.5 mm;
• the door should have high-quality insulation, preferably from several layers;
• the presence of a seal along the contour will reduce heat loss;
• interior decoration is better to choose from wood with moisture treatment;
• do not purchase fiberglass models for an apartment.

When choosing, you should be guided by the standard characteristics for doors: width of the leaf, opening side (right or left), box dimensions, etc. The door can be ordered online in the online store, but it is better to independently inspect the option you like, if possible, visually assess the presence, type of thermal breaks.

When choosing, it is necessary to evaluate how well the popular models are made, cope with the tasks in the opinion of buyers. Also, what to look for in the first place is the reputation of the manufacturer. Top manufacturers:

• Torex;
• Termo;
• Guardian;
• Groff;
• Condor;
