Entrance doors for a private house insulated

The choice of an appropriate entrance door should not be dictated solely by a sense of aesthetics. It is much more important to consider the technical characteristics. Of course, the doors are the first things that guests will see, so we care about their appearance, but their main task is to ensure the safety of housing, residents, isolation of the inside of the house from adverse external factors - rain, wind, cold, noise. They should be warm, safe. This requires significant costs, quality is reflected in the price.

How to buy entrance doors, metal or other materials, what to look for, so as not to be mistaken in the choice and provide the necessary insulation of housing from external weather factors? Our article is devoted to these questions.

In addition to ensuring security, the entrance door to a private house should be insulated, protecting the home from external factors:

  • cold,
  • wind,
  • noise.

Doors must be resistant to prolonged exposure to sunlight.

Heat insulation, heat transfer coefficient

In terms of thermal comfort, properly insulated exterior doors can reduce heat loss by 30% or more. With poor insulation, heat disappears from the premises as a result of uncontrolled excessive ventilation.

In order not to be mistaken, before you make the final decision on the purchase of a particular model, ask the sales assistant if the model you like is isolated. Insulation is estimated by heat transfer coefficient.

The heat transfer coefficient, denoted by the symbol U, indicates the amount of heat per unit of time per 1 m² of surface. The lower the heat transfer coefficient, the better the isolated housing.

Attention! The manufacturer can specify the coefficient for the entire door with the box or only for those panels where its value is more favorable. Therefore, this should pay attention.

For external doors, the optimal heat transfer coefficient is no more than 1.7 W / m²K.

Manufacturers whose products meet the requirements of the standard in order to increase the attractiveness and confidence in the product provide the appropriate certificates to customers confirming the quality of the products.For a standard exterior door, the heat transfer coefficient should not exceed 2.6 W / m²K.

What affects the insulation?


The level of insulation is influenced by several factors:

  1. the main type of material of which the door is made;
  2. web design;
  3. rebate;
  4. seals;
  5. the presence of glazing;
  6. correct installation;
  7. fittings.

How to choose street entrance doors? Pine models are much warmer than oak. A warmer, thicker fabric with a large amount of thermally insulating material (polystyrene, mineral wool, polyurethane foam) is warmer. The door needs to be precisely adjusted to the door frame to protect it from the cold, it is necessary to seal the threshold part carefully.

An important structural element that has a significant impact on the final insulation - rebate. The fold is a ledge formed on the edge of the web, thanks to which the structure is more hermetic. Consider the factors affecting the insulation, more.

Materials and insulation


Doors are made of various materials. The most common materials are:

  • solid wood;
  • steel;
  • aluminum;
  • plastic - the material is not widely used for the production of door leaf, even if it is characterized by high thermal, acoustic insulation, but is sometimes found on the market.

The entrance warmed metal doors make, as a rule, of steel. Steel plates of the sheet are painted or covered with veneer, beautifully imitating natural wood, its texture.

Filling the metal web is made from heat and sound insulation materials:

  • mineral wool;
  • polystyrene foam;
  • freon polyurethane foam.

The choice is wide. Each material has strengths and weaknesses.

Wooden doorscharacterized by:

  • high acoustic insulation;
  • aesthetic, elegant appearance;
  • do not work with variable humidity;
  • exposed to rain, snow, high humidity;
  • installed only on a covered porch, under the visor;
  • weakly resistant to mechanical damage, easily broken.

Steel modelscharacterized by the following parameters:

  • very resistant to mechanical damage;
  • heavy;
  • Exterior metal doors consist of 2 sheets of sheet metal, between which insulating materials are placed, therefore it is difficult to ensure high parameters of heat insulation, the heat transfer coefficient is 1.5-2;
  • high resistance to cracking.

PVC modelshave the following characteristics:

  • high sound absorption;
  • high thermal insulation - use polyurethane foam filler;
  • ease of assembly;
  • combustibility;
  • poor stability;
  • low resistance to cracking;
  • after damage to PVC, it is difficult to recover, but they have many positive aspects:

Glazing, window

In the canvas there may be a window through which the hallway lighting will significantly improve. The larger the window, the lower the insulating properties of the door in this place. Glazing perform narrow, made using special glass with thermal insulation. Often, anti-burglar glass is used to increase safety in glazing.

Compactors, acoustic protection

A reliable door should have seals mounted on the perimeter of the canvas frame. Seals protect housing from wind, thermal bridges. High-quality seals have excellent sound insulation - the smallest gap around the perimeter of the frame, the sash will significantly impair the ability of the structure to absorb sound.

Acoustic isolation is determined by the symbol Rw. The higher the acoustic insulation coefficient, the better.Exterior door models are presented on the market, in which the Rw index is very high, even for constructions equipped with glazing.

Silence, comfort in the rooms guarantees Rw in the range of 30-35 dB.

Such models have windows made of 2 sheets of glass 4-6 mm thick, the space between them is filled with a special gas that improves the insulating properties. If good insulation is required, it is advisable to look for an option among models with pressure seals.

Fittings

Buying a new door, you should not use old accessories. Modern accessories for carpentry work is performed with high precision, is one with the product. By adjusting the old fittings to the new carpentry, the heat-insulating properties are reduced, a bad visual effect is created.

Proper installation is a prerequisite for thermal insulation.

Proper installation plays an important role in ensuring proper thermal insulation for entrance doors. Special attention should be paid to the protection of sensitive areas where the frame is connected to the wall. Professionals recommend that the so-called "warm installation", which is done at the appropriate stage of construction.

Wooden doors are installed after wet construction work inside the building - after the application, drying of plaster.

After installation, it is necessary to protect the canvas with insulation from moisture, sunlight using:

  • vapor barrier tape - from the premises;
  • vapor permeable - from the street.

To close thermal bridges, it is better to insulate all joints with:

  • polystyrene,
  • mineral wool.

The threshold must be isolated using:

  • bitumen tape,
  • other waterproof material.

Lobby

Very effectively affects the reduction of heat loss in the building lobby. Hall does not allow direct mixing of indoor and outdoor air. In the lobby in winter the temperature is slightly lower than in other rooms. As a result, the door leaf is not exposed to such a sharp temperature difference, acting inside the building and outside.

To avoid unpleasant sensations after frost gets into the rooms, the lobby is not heated, specifically keeping the temperature slightly lower than in other rooms, or heated to a minimum.

Dimensions

  • Widthdepends on the use of the door.Choosing the front door, pay attention to the sufficient width so that people could freely pass through them, bring furniture and equipment. Standard width is 90 cm.
  • Height. The standard is considered to be at least 201 cm high. The door opening is at least 6-7 cm larger.

Resistance to cracking

Doors are offered in different resistance classes (Rc from 1 to 6). The higher the value, the better, the resistance to cracking increases.

  • Choosing a lower class model, you should expect only basic protection. When hacked, a thief will not have to strain too much by cracking the door leaf.
  • The model of high quality, high-class resistance to cracking is difficult to open, the robber using powerful tools will be helpless.

Conclusion

Exterior doors are required for each dwelling. Guests see them at the first contact, they must look good and have the right parameters. The front door should be chosen carefully. The right choice will help reduce heat loss, provide low heating bills. Before buying, you need to check 3 basic parameters: heat insulation, acoustic protection, resistance to cracking.It is also important what material the canvas is made of. There is no perfect door leaf. It is important that the selected models have the most important parameters.
