With the arrival of cold weather from the owners who have a reliable input metal doors a global problem appears. The appearance of the door is worsening – water drops appear on it, hoarflash, ice on the inner surface. Changes atmosphere of residential premises. If you insulate the front door, then all this can be avoided. You can solve this task yourself without attracting specialists.
Materials and tools
Modern materials allow any home to protect from cold.
For insulation of metal structures use:
- mineral wool;
- polyurethane foam;
- Foil isolon, foam;
In addition to insulation, a manual plumbing tool will be needed:
- roulette, pencil;
- screwdriver, screwdriver;
- Drill with metal drills;
- scissors or sharp knife;
- sewn, hacksaw, electrolovik;
- sandpaper, scotch;
- glue (liquid nails), screws – self-tapping screws;
- acetone or alcohol.
- MDF – decorative panels or slabs;
- Decorative film with a pattern repeating wood texture;
- paints and varnishes;
- dermatin, imitating skin.
You can not neglect the safety technique.
When performing locksmith, it is important to have:
- Polymer coating gloves;
- glasses to protect the eyes from mechanical particles, fragments;
- Respirator to protect the respiratory organs.
What insulation is better?
The safety of heat in your home depends on the quality heat-insulating material. When it is elected, it is important to take into account the design of metal doors and the location of their location.
Styrofoam Received by foaming (gas filling) polymers. One of the cheapest materials. Has excellent thermal insulation properties, not afraid of dampness and saves the form. Polyfoam will well keep warm on the door in the apartment. In a private house, he will not be reliable enough, but if it is supplemented by the mounting foam and foil isolon, he will serve for many years. In case of fire, chemical compounds harmful to human health.
For good sound insulation, there are enough plates with three centimeters thick.
Polystyrene foam – material obtained from polystyrene and other styrene copolymers. More expensive than foam. Moisture-resistant insulation having thermal insulation and sound insulation properties. Denser foam plastic, wear-resistant, safe for health. There are refractory modifications.
Polystyrene – Material obtained by polymerization of styrene. It has dielectric properties, hard, has high thermal insulation properties, moisture resistant.
The materials listed above are ideally suited as the insulation of the input door of the private house, the country house. They will greatly provide protection against moisture and frost.
Mineral wool – inorganic fibrous material. Effective as insulation. In the same price category as foam. Depending on the fiber, it is divided into groups: glass wool, slag and stone (basalt). It is made of natural non-combustible materials, environmentally friendly. Sold in the form of rolls or plates. If it is used to insulate the door in a private house, water-repellent material is required.
Polyurene Foolder – Material that refers to gas-filled polymers. This group includes: foam rubber, ready-made thermal insulation panels, mounting foam. Porolon has good thermal insulation and sound insulation properties. When burning is highly toxic, refers to strongly combustible substances. Exception is the foam rubber special purpose CMHR. It is distinguished by special elasticity and fire safety.
Foil Isolon, Penophol – Eco-friendly material. In the process of its manufacture, foil and foamed polyethylene are used. This is a modern, popular, economical, wear-resistant, moisture-resistant insulation. Has excellent soundproof properties.
Thermal insulation door frame with their own hands
For high-quality insulation of the entrance door, it is important to carry out the necessary work on the insulation of the box. It happens that workers, in a hurry to install the door, leave noticeable gaps between the box and sides of the doorway. When you start warming up your door, you must fill all the slots of the mounting foam. After it freezes, all discover parts must be cleaned. Joints to attach and put in order.
After that, it is necessary to eliminate the possible gaps between the metal door and the box. To do this, we purchase a ribbon silicone seal (can be foam). On the perimeter of the door box doors process alcohol or acetone. In those places where they come into contact, we glue the seal. In order to stick it exactly in the corners, we take out of two tapes of the sealant, sharp knife or scissors carefully cut off at an angle of 45 degrees, remove the cut parts, and the edges of the seals are tightly pressed in the corner. Check the doorway for draft.
Stages of iron model
The sequence of action during the trim of the old door depends on its design. If the design is more modern and metal panels are attached to the base screws, insulation is carried out internally. Getting started to inner warming, remove the metal structure, put onto the working surface. We unscrew the screws and remove the metal panel (so that the screws are unscrewed well, lubricate them with machine oil). Roulette remove the dimensions of the internal cells of the door.
Carefully measure the insulation material and cut off. Be sure to cut the place under the door lock and the eyes. For old doors, foam or foil stone wool are remarkably suitable. We process the inner surface of the old design with glue (liquid nails) and glue the prepared insulation. If the slots are left between the old door and insulation, fill in their mounting foam. It is necessary to work carefully, squeezing the mounting foam to small portions. It is important to follow, so that it does not get on the mechanism of the battle lock. For additional sound insulation between the insulation and metal sheet, we launch foil isolon. Close the design of the metal web and screw the screws.
If the old door is made by fixing metal panels with welding, then proceed to the warming of the old door, applying an external method. Preparing wooden bars 20 (30) x20 mm. We measure the parameters and cut the rails at the required length. With the help of a drill, we do the holes of the future mount in the metal canvase. We collect the foundation of harvested wooden bars and fastened self-drawing to a metal sheet.
Preparing the insulation for the specified sizes. We swell and glue the insulation in the cells between the rails. Fix MDF panel or slab screws. Additionally, for sound insulation outside or from the inside, you can handle the door dermatitin. To do this, clamping dermatin and brackets fix. Lubricate with glue (liquid nails), the lining and the bending of dermatina and tightly press to the metal canvase. This work is painstaking. In the last stage, install door locks, knobs, eyes. Return the finished door to the place.
When the single-layer metal door is trimmed, it is necessary to measure cells between rigidity ribs. Cut the inner material for the specified size. Meritally glue the insulation in the cavity. Slots and minor gaps by eliminating using mounting foam. Decorating the MDF-panel.
Improve the characteristics of Chinese products
Chinese production door is an unintended design. For her insulation, remove the door, put horizontally. Remove the handles, eyes, castles. Then begin to fix the frame and ribs of stiffness both with the inner and the outside. Therefore, we choose a wooden beam with a thickness of 20 * 20 mm, or more (repel from the thickness of the insulation material). If you wish, you can weld the metal base, attach it with self-strains or weld to the door of the door, the joints of the joints are filled with the mounting foam.
Next step – laying insulation. If fibrous materials are selected (mineral wool, stone wool), spread the water-repellent material in size more than the cavity of the base, about 200 mm, fasten the glue (liquid nails) and weathered the wool, pre-cut a slightly larger web size than the size of the base cells, and cover the other layer of water-repellent material. The edges of the film tightly convert to the top layer and fix the scotch.
Insulation cover with a foil or foil with a foil side into the room. So improve sound insulation doors. Polyfoam, polystyrene foam, polystyrene, the isolon follicated in waterproofing does not need, as they themselves have water-repellent properties. Next, we measure the distance between the ribs between the ribs, we cut a slightly larger insulation than necessary to avoid the formation of the cavity between the insulation and the basis of the door. We glue the insulation in the cavity glue (liquid nails).
Attached to the surface of the base asking the mounting foam in the joints of the joints. The next step is to decorate the design sheet of MDF panel or alternative material. It is important to remember that the decorative panel must be attached from the bottom up. Fix, put locks, eyes and handles, hang the door. Now the door retains heat at home, and also protects against noise.
Warming without dismantling is produced in three ways. The first is suitable for metal doors with removable panels. To do this, unscrew screws, starting with the bottom, moving upstairs. Unscrew not all screws, put the metal door to the stand. Gently promote the insulation treated with glue (liquid nails), fix. For this method, foil isolon is suitable. Screw the screws. The door is ready.
The second method is suitable for solid metal doors. On top of the holes, pre-making sure that there are no more holes and gaps. We take any crumbly insulation (non-combustible bulk wool, granulated foam, vermiculitis, sawdust). Fall asleep it into the holes, tapping the door to achieve full filling of the cavity. This method is absolutely not suitable for doors with battle locks. After filling on the holes we put the plugs.
The third method is an external insulation. Fully follow the phased method of fastening the external method. You can stick insulation on the inner surface of the door.
The appearance of the entrance door always emphasizes the owner status. Therefore, in a private house, requirements are especially high. It is important to take care of a worthy image. Metal doors market are saturated with a variety of products. I am glad and the fact that the doors can be ordered by personal project.
And yet, how nice to work on the design itself! We offer several ideas for decorating metal doors with their own hands. The design of the door in the apartment is interested in the fact that the outside can be decorated so as not to attract someone else’s attention. The simplest, affordable way is the design of a metal door with bright fittings. Outside, you can attach new numbers, put stylized handles, loops, locks.
For those who prefer natural materials, we can recommend attaching the inner side of the door of MDF panels or simple wooden slats. The design and color of the metal door of the private house, as well as the form depend on what style house or cottage is built. For fittings you can use forged parts, use stained glass windows, glass splashes. And instead of a modern call, you can hang a handle-pouch, gong.
